Selecting a Traction Unit The capabilities of the machine may vary depending on the size and type of traction unit. Traction Unit Function Requirements and Recommendations Hydraulic system The traction unit must have a rear-attachment hydraulic system with an open center auxiliary hydraulic valve. A 4-wheel-drive vehicle improves performance on hills. Towing capacity When fully loaded, the machine can weigh up to 7,000 kg (15,432 lb). Do not go beyond the limitations of the traction unit.

Set the electric brake, refer to Adjusting the Brake Controller (page 22). g273356 Testing the Hydraulic Connections Important: Test the hydraulic connections before hydraulics operating the machine for the first time. 1. Check the hydraulic-fluid level in the reservoir of the traction unit and add fluid if needed; refer to the traction unit operator’s manual.

Set up the brake controller; refer to the installation and operating instructions of the brake controller. motion. • Using the machine demands attention. Failing to operate tow vehicle safely may result in an accident, tip-over of the tow vehicle, and serious injury or death.
Slope Safety • Do not carry loads that exceed the load limits of the machine or the tow vehicle. • Slopes are a major factor related to loss of control • The stability of loads can vary—for example, high and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, do the following: loads have a higher center of gravity.
• Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. • Always keep the traction unit in gear when going down slopes. Do not coast downhill (applicable only to gear-drive units). Using the Rear-Jack Leg Use the rear jack leg to support the machine when you disconnect it from the traction unit.

Turning the Machine Power On/Off Towing the Machine Perform the following steps when towing the machine: • Before operating the machine, stow the jack and EH Models rear jack leg. When finished working with the machine, always press the E-STOP button (Figure 29) to disable the electrical system. When beginning work with the machine, you must pull the E-STOP button back out before turning on the handheld remote.
Right Valve Operating the Hydraulic Control Valves The right valve controls optional attachments. • To turn on the optional attachment, pull on the SH Models control lever. There are three hydraulic control valves located on the left fender of the machine (Figure 30). Important: Do not pull the option lever into the ON position without an option mounted. This can damage the floor motor and stop the machine. • To turn off the option, return the control lever to the center position.
Handheld Remote Operating the Hydraulic Controls and Options EH Models Remote Control System The remote control system consists of a handheld remote, a +12 to +14.4 VDC Base Unit, and a wire harness.

Lubrication Grease Specification No. 2 lithium grease Lubricating the Bearings and Bushings g272505 Service Interval: Every 50 hours When operating the machine in extremely dusty and dirty conditions, lubricate the bearings and bushings daily. Lubricate grease fittings immediately after every washing, regardless of the interval specified. g272506 Figure 45 1. Hydraulic-cylinder support 1. Wipe the grease fitting clean so foreign matter cannot be forced into the bearing or bushing. 2.
Drive System Maintenance Checking the Tire and Wheels Service Interval: Before each use or daily 1. Check the tire air pressure is 172 kPa (25 psi) for 84 cm (33 inch) tires and 207 kPa (30 psi) for 81 cm (32 inch) tires, or as recommended by the tire manufacturer. 2. Check the tires for excessive wear or visible damage. 3. Check that the wheel bolts are tight, and none are missing. g014132 Figure 48 Changing Tires Changing an Outside Tire g014133 1. Engage the parking brake of the traction unit.
4. Chock the tires at the opposite side of the damaged tire. 5. On the side with the damaged tire, remove the 4 bolts and 4 locknuts securing the walking beam suspension bearings to the chassis. Brake Maintenance Inspecting the Electric Brakes Loosen but do not remove the outside wheel nuts to provide clearance for bearing bolts. 6.
Inspecting the Brake Shoes and Linings • Brake anchor pin • Actuating arm bushing and pin • Areas on the backing plate that are in contact with Service Interval: Monthly the brake shoes and magnet lever arm When a brake shoe becomes worn, replace both shoes on each brake, and both brakes on the same axle. This ensures that the brakes remain balanced. • Actuating block on the actuating arm Important: Do not allow grease to contact the brake linings, drums, or magnets.
Checking the Hydraulic System Hydraulic System Maintenance Service Interval: Before each use or daily Hydraulic System Safety 1. If you find a leak, tighten the fitting, or replace or repair the damaged part. • Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor. 2. • Ensure that all hydraulic-fluid hoses and lines are Check the hydraulic hoses for wear or damage.
Maintaining the Conveyor Belt Optional Attachments Checking the Optional Attachments Checking the Conveyor Belt and Rollers Service Interval: Before each use or daily • Check that the quick attach brackets are secure Service Interval: Every 40 hours and that the safety clips are installed. Monthly Replace any missing safety clips. • Check that the conveyor belt tracks straight on the • Check that the optional attachment is securely rollers and it does not slip.
WARNING Operating the conveyor belt with the guards and covers removed can cause serious injury. Use extreme caution around moving parts with safety guards removed. 6. Turn on the conveyor belt. 7. If belt slips, tighten the tension bolts evenly (with machine off) half a turn and check if the belt slips again. Continue until the belt moves without any slippage. 8. Give both tensioning bolts another half turn. At this point you should have proper tension. 9.
Note: The front idler roller is supported by two pillow block bearings sitting in an upper and lower guide (one set on each side of the machine). 7. Support the front idler roller. 8. Go to the right front corner and remove the locking collar that holds the pillow block bearing on the shaft. Do this by backing off the set screws and turning the locking collar counterclockwise. Using a hammer and punch, tap the locking collar counterclockwise until it releases from the shaft. 9.
Installing the Belt 6. To install a new belt, reverse the above instructions, but keep in mind the following important notes and instructions. Check that the chain is sufficiently lubricated, and the sprockets are secure to the shafts. 7. Replace the rear conveyor drive guard. Important: The conveyor belt is designed to work primarily in one direction. Ensure that the painted arrow in the middle of the belt is pointing toward the rear of the machine (looking down from above).
Maintaining the Hopper and Rear Gate Cleaning Checking the Conveyor Seals and Rear Gate Seal Salts, road tar, tree sap, fertilizers, or chemicals may damage the painted finish of the machine. Wash off these deposits as soon as possible with detergent and water. Additional cleaners or solvents may be needed, but ensure that they are safe for painted surfaces. Washing the Machine Service Interval: Before each use or daily Check all rubber seals for damage or wear.
10. If removed, install the belt cleaning scraper assembly. Storage Ensure that the scraper is as vertical as possible but contacts the belt. Before storing the machine for the season: 1. Park the machine on a hard, level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine. 2. Remove the handheld remote. 3. Remove the batteries from the remote. 4. Thoroughly wash the machine; refer to Washing the Machine (page 52).
Troubleshooting Checking Fault Codes EH Models If the Diagnostic LED indicates that there is a system fault (refer to Diagnostic LED Function (page 19)), check the fault codes to determine what is wrong with the machine. Entering Diagnostic Mode and Checking the Codes 1. Push the E-STOP button down to turn off the power. 2. Pull the tethered cap off the two diagnostic, shunt connectors (Figure 58, A). 3.
