SUMMARY OF SAFETY PRECAUTIONS FOR LIFTING IN DIGGING MODE DANGER AVOID DEATH Unsafe use of the excavator while making rated lifts could cause serious, potentially fatal injuries or extensive damage to the machine or nearby property. Do not let anyone operate the machine unless they've been properly trained and understand the information in the Operation and Maintenance Manual. To lift safely while in Digging Mode, the following items must be evaluated by the operator and the work site crew.
WARNING AVOID DEATH OR SERIOUS INJURY If you need more information or have any questions or concerns about safe operating procedures or working the excavator correctly in a particular application or in the specific conditions of your individual operating environment, please consult your local DOOSAN representative. UNAUTHORIZED MODIFICATIONS Any modification made without authorization or written approval from DOOSAN can create a safety hazard, for which the machine owner will be held responsible.
Safety Features Be sure that all guards and covers are installed in their proper position. Have guards and covers repaired immediately if damaged. Be sure that you understand the method of use of safety features such as safety lock lever and the seat belt, and use them properly. Never remove any safety features. Always keep them in good operating condition. Failure to use safety features according to the instructions in the Operation and Maintenance Manual could result in serious bodily injury.
Clothing and Personal Protective Items Secure long hair, and avoid loose clothing and jewelry. These items have the tendency to catch on controls or protrude into parts and cause serious injury or death. Do not wear oily clothes. They are flammable. Full eye protection, a hard hat, safety shoes and gloves may be required at the work site. While working on the machine, never use inadequate tools. They could break or slip, causing injury, or they may not adequately perform intended functions.
Recommendations for Limiting Vibrations 1. Select the right machine, equipment and attachments for a particular application. 2. Replace any damaged seat by a DOOSAN genuine part. Keep the seat maintained and adjusted. 3. • Adjust the seat and suspension for the weight and size of the operator. • Inspect and maintain the suspension and adjustment mechanisms of the seat regularly. Check that the machine is properly maintained. • Tire pressure, brakes, steering, linkages, etc. 4.
Mounting and Dismounting Before getting on or off the machine, if there is any oil, grease, or mud on the handrails, steps, or track shoes, wipe it off immediately. Always keep these parts clean. Repair any damage and tighten any loose bolts. Never jump on or off the machine. In particular, never get on or off a moving machine. These actions may lead to serious injury.
Precautions When Handling Fluids at High Temperature Immediately after operations are stopped, the coolant, engine oil, and hydraulic oil are at highest temperatures and the radiator and hydraulic tank are still under pressure. Attempting to remove cap, drain the oil or coolant, or replacing the filters may lead to serious burns. Always wait for the temperature to go down, and follow the specified procedures when carrying out these operations.
Injury from Work Equipment Do not enter or put your hand, arm or any other part of your body between movable parts, such as between the work equipment and cylinders, or between the machine and work equipment. If the control levers are operated, the clearance between the machine and the work equipment will change and this may lead to serious damage or personal injury. If going between movable parts is necessary, always position and secure the work equipment so it cannot move.
Protection from Falling or Flying Objects On work sites where there is a danger that falling or flying objects may hit the operator's cabin select a guard to match the operating conditions to protect the operator. Working in mines, tunnels, deep pits or on loose or wet surfaces could produce danger of falling rock or hazardous flying objects. Additional protection for the operator's cabin could be required in the form of a FOPS (Falling Object Protective Structure) or window guards.
Accumulator The pilot control system is equipped with an accumulator. For a brief period of time after the engine has been stopped, accumulator will store a pressure charge that may enable hydraulic controls to be activated. Activation of any controls may enable the selected function to operate under force of gravity. When performing maintenance on the pilot control system, the hydraulic pressure in the system must be released as described in "Handling of Accumulator" on page 4-78.
BEFORE STARTING ENGINE Work Site Precautions Before starting operations, thoroughly check the area for any unusual conditions that could be dangerous. Check the terrain and condition of the ground at the work site, and determine the best and safest method of operation. Make sure the ground surface is as hard and horizontal as possible before carrying out operations. If there is a lot of dust and sand on the work site, spray water before starting operations.
If the ground collapses, the machine could fall or tip over resulting in serious injury or death. Remember that soil after heavy rain, blasting or after earthquakes, is weakened. Newly laid earth and the soil near ditches is typically loose. It can collapse under the weight of vibration of your machine and cause your machine to tip over. Install the head guard (FOPS) if working in areas where there is a danger of falling rocks.
Engine Starting Walk around your machine before getting in the operator's cabin. Look for evidence of leaking fluid, loose fasteners, misaligned assemblies or any other indications of possible equipment hazard. All equipment covers and machinery safety guards must be in place, to protect against injury while the machine is being operated. Look around the work site area for potential hazards, people or property that could be at risk while operation is in progress.
Before Operating Machine If checks are not carried out properly after starting the engine, it can result in a delay in discovering abnormalities in the machine, and this may lead to personal injury or damage to the machine. Carry out the checks in an open area where there are no obstructions. Do not let anyone near the machine when carrying out the checks. • Check the operating condition of the equipment, and the movement of the bucket, arm, boom, travel, and swing systems.
Seat Belt Check seat belt daily for correct function. Inspect seat belt system more often if machine is exposed to severe environmental conditions or applications. Conduct the following inspections and replace seat belt system as necessary: 1. Check webbing. If system is equipped with a retractor, pull webbing completely out and inspect full length of webbing. Look for cuts, wear, fraying, dirt and stiffness. 2. Check buckle and latch for correct operation. 3.
MACHINE OPERATION When Swinging or Changing Direction of Travel Before operating the machine or the work equipment, always observe the following precautions to prevent serious injury or death. • Start and operate the machine only while seated. • When changing travel direction from forward to reverse or from reverse to forward, reduce speed early and stop the machine before changing travel direction. • Sound the horn to warn people in the area.
Travel Precautions Never turn the starting switch to "O" (OFF) position when traveling. It is dangerous if the engine stops while the machine is traveling. It will be impossible to operate the steering. TRAVEL POSTURE Attachment control levers should not be operated while traveling. Do not change selected travel mode (FAST/SLOW) while traveling. Fold in work equipment so the outer end of the boom is as close to the machine as possible, and is 40 - 50 cm (16 - 20 in) aboveground. 40 ~ 50 cm (16 ~ 20 in.
Traveling on Slopes Never jump onto a machine that is running away to stop it. There is a danger of serious injury. Traveling on slopes could result in the machine tipping over or slipping. 20~ 30 C m On hills, banks or slopes, carry the bucket approximately 20 - 30 cm (8 - 12 in) above the ground. In case of an emergency, quickly lower the bucket to the ground to help stop the machine. Do not travel on grass, fallen leaves, or wet steel plates.
Prohibited Operations Do not dig the work face under an overhang. This can cause the overhang to collapse and fall on top of the machine. FG000368 Figure 23 Do not carry out deep digging under the front of the machine. The ground under the machine may collapse and cause the machine to fall. Working heavy loads over loose, soft ground or uneven, broken terrain can cause dangerous side load conditions and possible tip over and injury. Travel without a load or a balanced load may also be hazardous.
Precautions for Operation Be careful not to mistakenly travel too close to the edge of a cliff. Use the machine only for its main purpose. Using it for other purposes will cause failures. To ensure a good view, always do the following: • When working in dark areas, attach working lights and front lights to the machine. If necessary, set up lighting at the work site. • Stop operations when the visibility is poor, such as in fog, mist, snow, and rain.
Roll Over Protective Structure (ROPS) The operator's cabin is a ROPS certified structure for protecting the seat-belted operator. It absorbs the impact energy of a rollover impact. Do not allow machine weight (mass) to exceed certified value on certification plate. If weight is exceeded, the ROPS structure will not be able to fulfill its safety function. Do not increase machine weight beyond certified value by modifying machine or by installing attachments on machine.
Protecting Cabin from Falling Object (Optional) In a work site where falling objects or flying objects are expected, be sure to install adequate protective devices for covering the cabin. 1 When using a breaker, be sure to install the front window protection guard (1, Figure 29). FG014374 Figure 29 In a work site where falling rocks can cause damage and possibly crush personnel, or in a mining operation, be sure to install the falling object protective structure (2, Figure 30).
Operate Carefully on Snow, Ice and in Very Cold Temperatures In icy cold weather avoid sudden travel movements and stay away from even slight slopes. The machine could skid off to one side very easily. Snow accumulation could hide or obscure potential hazards. Use care while operating or while using the machine to clear snow. Warming up the engine for a short period may be necessary, to avoid operating with sluggish or reduced working capacity.
Parking Machine Avoid making sudden stops, or parking the machine wherever it happens to be at the end of the workday. Plan so the excavator will be on firm and level ground away from traffic and away from high walls, cliff edges and any area of potential water accumulation or runoff. If parking on inclines is unavoidable, block the crawler tracks to prevent movement. Lower the bucket or other working attachment completely to the ground, or to an overnight support saddle.
MAINTENANCE Warning Tag Alert others that service or maintenance is being performed and tag operator's cabin controls – and other machine areas if required – with a warning notice. OSHA mandated control lever lockout can be made with any OSHA certified lockout device and a length of chain or cable to keep the safety lever in the fully lowered, nonnative position. Warning tags, for controls are available from DOOSAN distributors.
Proper Tools Use only tools suited to the task. Using damaged, low qualify, faulty, or makeshift tools could cause personal injury. There is a danger that pieces from, chisels with crushed heads, or hammers, may get into your eyes and cause blindness. HDO1037L Figure 36 Use of Lighting When checking fuel, oil, battery electrolyte, or window washing fluid, always use lighting with antiexplosion specifications. If such lighting equipment is not used, there is a danger of an explosion.
Burn Prevention When checking the radiator coolant level, stop engine, let the engine and radiator cool down, then check the coolant recovery tank. If the coolant level in the coolant recovery tank is near the upper limit, there is enough coolant in the radiator. Loosen the radiator cap gradually to release the internal pressure before removing the radiator cap. If the coolant level in the coolant recovery tank is below the lower limit, add coolant. Cooling system conditioner contains alkali.
Welding Repairs IMPORTANT When disconnecting or connecting connectors between ECU and engine, or connector between ECU and the machine, always disconnect the battery to prevent damage to ECU. If you do not follow this procedure, the ECU will be damaged and/or the engine will not operate properly. When performing welding repairs, perform welding in a properly equipped place. Repairs must be performed by a qualified welder.
Treatment for Electrical Welding to the Body Structure To prevent damage to ECU by electrical welding, please observe the following procedures: 1. Open the door of the battery cover. 2. Detach the cover after loosening the bolts on the battery. 3. Detach the positive and negative terminal cables from the battery. 4. Detach the undercover, and after that detach the connector (1) from the ECU that are installed at the engine. FG000312 Figure 40 5. Proceed with welding. 6.
Precautions for Removal, Installation, and Storage of Attachments Before starting removal and installation of attachments, decide on the team leader. Do not allow anyone except the authorized workers close to the machine or attachment. Place attachments that have been removed from the machine in a safe place so they do not fall. Put up a fence around the attachments and take other measures to prevent unauthorized persons from entering.
Prevention of Crushing and Cutting You should always have at least two people working together if the engine must be run during service. One person needs to remain in the operator's seat, ready to work the controls or stop the machine and shut off the engine. Unless you are instructed otherwise, never attempt adjustments while the machine is moving or while the engine is running. Stay clear of all rotating parts and moving parts. Keep objects away from moving fan blades.
Action When Abnormality Is Found During Inspection If any abnormality is found during inspection, always carry out repairs. In particular, if the machine is used when there are still problems with the brake or work equipment systems, it may lead to serious injury. If necessary depending on the type of failure, please contact your DOOSAN distributor for repairs.
Waste Materials Physical contact with used motor oil may pose a health risk. Wipe oil from your hands promptly and wash off any remaining residue. X Used motor oil is an environmental contaminant and may only be disposed of at approved collection facilities. To prevent pollution of the environment, always do the following: • Never dump waste oil in a sewer system, rivers, etc. • Always put oil drained from your machine in containers. Never drain oil directly onto the ground.
BATTERY Battery Hazard Prevention Battery electrolyte contains diluted sulfuric acid and batteries generate hydrogen gas. Hydrogen gas is highly explosive, and mistakes in handling them can cause serious injury or fire. To prevent problems, always do the following: • Do not smoke or bring any flame near the battery. • When working with batteries, ALWAYS wear safety glasses and rubber gloves. • If you spill battery electrolyte on yourself or your clothes, immediately flush the area with water.
Boost Starting or Charging Engine Batteries If any mistake is made in the method of connecting the booster cables, it can cause an explosion or fire. Always do the following: • Turn off all electrical equipment before connecting leads to the battery. This includes electrical switches on the battery charger or boost starting equipment. • When boost starting from another machine or vehicle do not allow the two machines to touch. Wear safety glasses or goggles while required battery connections are made.
TOWING Precautions When Towing Cloth If any mistake is made in the method of selecting or inspecting the towing wire or in the method of towing, it may lead to serious personal injury. Always do the following: • Always use the method of towing given in this Operation and Maintenance Manual. Do not use any other method. • Use leather gloves when handling the wire rope.
SHIPPING AND TRANSPORTATION Obey State and Local Over-the-Road Regulations Check state and local restrictions regarding weight, width and length of a load before making any other preparation for transport. The hauling vehicle, trailer and load must all be in compliance with local regulations governing the intended shipping route. Partial disassembly or teardown of the excavator may be necessary to meet travel restrictions or particular conditions at the work site.
EXCAVATOR RATED LIFT CAPACITY TABLES WARNING AVOID DEATH OR SERIOUS INJURY Let everybody be away from the boom cylinder. While lifting operation, boom, arm, bucket hoses might burst and then high-pressure oil will be ejected at high-speed. If that failure mode takes place, handling weight or front structure might fall by its gravity to the ground to cause fatal injury to the person. When changing the hoses record the part numbers of the hoses to factory log book.
Avoid traveling with a suspended load. Before swinging (or if required, traveling), bring the load into an arm position (radius and height) that has a safer weight capacity rating and adequate movement clearance. The operator and all work site personnel must be thoroughly familiar with safety instructions and procedures within this Operation and Maintenance Manual.

ENGINE COOLING SYSTEM General Keeping an engine's cooling system in peak operating condition can have many benefits in keeping a machine in good operating condition. A properly functioning cooling system will improve fuel efficiency, reduce engine wear, and extend component life. Always use distilled water in the radiator. Contaminants in tap water neutralize the corrosion inhibitor components. If tap water must be used, Refer to "Table of Standards for Allowed Tap Water" on page 4-74.
Types of Antifreeze Ethylene Glycol - DOOSAN Genuine Antifreeze Solution (for all seasons) Ethylene glycol is a very hazardous material to human beings, animals and environment. Drain of coolant must be disposed of by an authorized waste material treatment service provider. The color does not provide a standard. Unauthorized coolant may have the same color. Please check the label on the container. Use genuine product. IMPORTANT Do not mix solutions from different manufacturers.
Antifreeze Concentration Tables Ethylene Glycol - DOOSAN Genuine Antifreeze Solution (for all seasons) (2,000 Hour/1 Year) Ambient Temperature Cooling Water Antifreeze -20°C (-4°F) 67% 33% -25°C (-13°F) 60% 40% -30°C (-22°F) 56% 44% -40°C (-40°F) 50% 50% NOTE: The concentration shall be kept at 50% and in worst case at 30% minimum for the least corrosion resistance. NOTE: Replacement cycle of the DOOSAN Genuine Product is 2,000 hours or one year.
FUEL TRANSFER PUMP (OPTIONAL) IMPORTANT Dry operating fuel pump for more than fifteen seconds can cause wear and/or damage to pump. • Cooling and lubrication of pump is achieved by fuel passing through pump. If pump is dry operated, heat generated by moving parts will cause damage to pump rotors, vanes and seals. Do not operate pump for more than fifteen minutes at a time. • Continuous usage of pump over recommended time interval will cause overheating of motor and will result in causing motor damage.
WARNING AVOID DEATH OR SERIOUS INJURY If there are any sign of leakage while operating transfer pump, inspect the following components to prevent any fires or hazardous fuel spills. • Check all hoses leading to and from the transfer pump. • Check all hose clamps. • Check transfer pump inlet port. The transfer pump is used to transfer fuel from a refueling source to the fuel tank. A check valve is installed in the inlet hose to prevent fuel from flowing back from fuel tank to source.
1. Remove strainer cap (4, Figure 124) from strainer (3) on end of inlet hose (5). NOTE: Keep strainer cap (4, Figure 124) in a safe location to reseal strainer (3) after refueling is complete. 2. Insert inlet hose (5, Figure 124) into refueling tank. 3. Turn fuel pump switch (Figure 125) inside of battery box on front side to "I" (ON) position. NOTE: Transfer pump rate of flow is approximately 35 lpm (9.24 U.S. gpm). Use extra care not to overfill fuel tank so fuel does not over flow. 4.
HANDLING OF ACCUMULATOR WARNING AVOID DEATH OR SERIOUS INJURY Even though the engine is stopped, the hydraulic accumulators for the pilot system are still charged. Do not disconnect any pilot system hoses until accumulator pressure has been released from the circuit. To release pressure, turn the starter switch to "I" (ON) position and operate all hydraulic control levers and forward/reverse travel levers.
TRACK TENSION WARNING AVOID DEATH OR SERIOUS INJURY Measuring track tension requires two people. One person must be in the operator's seat, operating the controls while the other person makes dimensional checks. Block frame to make sure the machine won't move or shift position during service. Warm up the engine to prevent stalls, park the excavator in an area that provides level, uniform ground support and/or use support blocks when necessary.
4. A track that is properly adjusted may have a different sag according to the track options. Contact your dealer for information. Terrain Type Distance "A" Normal 275 ~ 305 mm (10.8 ~ 12.0 in) WARNING AVOID DEATH OR SERIOUS INJURY The track adjusting mechanism is under very high-pressure. NEVER release grease pressure too fast. The track tension grease valve should never be loosened more than one (1) complete turn from the fully tightened down position. Bleed off grease pressure slowly.
VENTING AND PRIMING HYDRAULIC SYSTEM Main System Pump NOTE: If pump is run without sufficient oil in the main hydraulic pump, damage can occur. Always vent pump of air after draining hydraulic system. 1. With the engine stopped, remove vent plug (Figure 130) to see if any oil is present. 2. If oil is not present, fill pump with oil through port (Figure 130). 3. Install vent plug (Figure 130) first. 4. Start engine and run it for several minutes at low idle engine speed.
Swing Motor IMPORTANT If the air is not vented from the system, it will cause damage to the swing motor and bearings. NOTE: Perform this only when oil has been drained from swing motor. 1. Stop engine. 2. Disconnect drain hose and fill swing motor case with hydraulic oil. 3. Connect the drain hose. 4. Start engine and set throttle at "LOW IDLE" and swing upper structure slowly two full revolutions to the left and right.
