SAFETY PRECAUTIONS Intended use Power Cut wear protective goggles (C) or visor when using the Power Cut. Use the Power Cut cutoff saw outdoors only, for trimming and cutting suitable materials, using cutting discs rated for this machine. Improper use: Never use the cutoff saw cutting discs for grinding or sanding (using the side of the cutting disc to remove material). The disc can break! Never use the Power Cut with saw blades, cutter blades, brushes etc.
- Always wear safety shoes or boots (G) with steel toes, non-skid soles, and leg protectors when working with the Power Cut. Safety shoes equipped with a protective layer provide protection against cuts and ensure a secure footing. - Always wear a work suit (H) of tough material with sufÞcient ßame-retardant qualities whenever working with the cutoff saw. Fuels / Refuelling - Go to a safe, level place before refuelling.
Cutoff discs - The protection hood must always be on! Change discs only with the engine off! - There are two basic types of cutoff discs: - For metal (hot cutting) - For masonry (cold cutting) NOTE: When using diamond cutoff discs, always make sure to observe the "direction of rotation" markings. Diamond discs should only be used for cutting masonry/brick/ concrete etc. - Cutoff discs are intended only for radial loading, i.e. for cutting.
Kickback and lock-in - - - - - When working with the Power Cut there is a danger of kickback and lock-in. Kickback occurs when the top of the cutting disc is used for cutting (15). This causes the Power Cut to be thrown back toward the user with great force and out of control. Risk of injury! To prevent kickback, observe the following: Never cut with the section of the cutting disc shown in Þgure 15.
When using synthetic resin cutting discs, always observe the following: Cutting masonry and concrete IMPORTANT! CAUTION: Always wear approved respiratory protection! - Synthetic resin cutting discs can absorb moisture. This moisture can cause the disc to become unbalanced at high speed. This imbalance can cause the disc to break. - Do not cool resin cutting discs with water or other ßuids.
In wet cutting, the disc is wetted at an equal rate on both sides by a trickle of water. MAKITA offers the right accessories for all wet cutting applications (see also "SPECIAL ACCESSORIES"). - Remove foreign objects such as sand, stones and nails found within the working area. Caution: Watch out for electric wires and cables! The rapid rotation of the cutting disc at the point of contact throws fragments out of the cut groove at high speed.
Maintenance - Before performing maintenance work switch off the Power Cut (27) and pull out the plug cap. - Always check the Power Cut before using it to make sure that it is in good working order. In particular, make sure that the cutting disc is properly mounted. Make sure that the cutting wheel is undamaged and suitable for the job it will be used for. - Operate the Power Cut only at a low noise and emission level. For this ensure the carburetor is adjusted correctly.

PUTTING INTO OPERATION CAUTION: Always turn off the engine and pull off the spark plug cap before doing any work on the Power Cut! Always wear protective gloves! CAUTION: Start the Power Cut only after complete assembly and inspection. For the the following work, use the assembly tools included with delivery: 1. 13/19 AF combination wrench 2. Allen key 3. Carburetor adjustment screwdriver 4.
Tightening the V-belt / Checking V-belt tension IMPORTANT: Exact V-belt tension is essential for maximum cutting performance with minimum fuel consumption. Improper V-belt tension will result in premature wear to the V-belt and V-belt wheel or damage to the clutch bearing. If the Power Cut is new or the V-belt has been replaced, retighten the V-belt after the Þrst hour of operation! NOTE: The two fastening nuts (11) must be loosened before tightening the V-belt or checking the tension.
MAKITA high-performance two-stroke engine oil (50:1) is available in the following sizes to suit your individual requirements: 100 ml order number 980 008 606 1 l order number 980 008 607 NOTE: For preparing the fuel-oil mixture Þrst mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Shake the Þnished mixture thoroughly before pouring it into the tank.
Starting the engine if necessary This model is Þtted with a semiautomatic decompression valve (1) to make starting easier. Press the rubber cover until you can feel it engage. This pushes in the deompression valve behind it. This in turn reduces the compression, so that it takes less force to pull the starter cord to accelerate the engine to its starting speed. The high pressure in the combustion chamber after the Þrst ignition automatically closes the decompression valve.
Cold starting: Grasp front handle Þrmly with one hand and press the Power Cut against the ground. Place left toe in the rear handguard. Push the combination switch (6) up (choke position). This will automatically activate the half-throttle lock. NOTE: If the Power Cut is mounted on the trolley, do not operate the gas lever (throttle) on the side of the trolley! Pull the starter cable out slowly until you feel resistance (piston is now just before top dead center). Press in the decompression valve (5).
Adjusting the carburetor NOTE: The grinding parts are equipped with an electronic ignition to limit the speed. At the factory the idling speed has been set to approx. 2500 rpm, but the running-in process of a new engine may require slight readjustment of the idling speed. Adjustments to the adjusting screws (L) and (H) may only be made by an authorised MAKITA service centre. Accordingly, the holes for the two screws are sealed shut.
MAINTENANCE CAUTION: Before doing any work on the Power Cut turn off the engine, remove the cutting disc, pull the plug cap off the spark plug and wear protective gloves! CAUTION: Start the Power Cut only after complete assembly and inspection.
Cleaning the protection hood Over time, the inside of the protective hood can become caked with material residue (especially from wet cutting), which if allowed to accumulate can hinder the free rotation of the cutting disc. For this reason the hood must be cleaned out from time to time. Take off the cutting wheel with spring washer and remove the accumulated material from inside the hood with a strip of wood or similar implement. Clean the shaft and all removed parts.
CAUTION: Turn off the engine before cleaning the air Þlter! Never clean out the air Þlter with compressed air! Do not clean the pre-Þlter and inner Þlter with fuel. The service life of the engine depends on the condition and regular maintenance of the Þlter elements.
Replacing the spark plug 7 8 CAUTION: Do not touch the spark plug or plug cap if the engine is running (high voltage). Switch off the engine before starting any maintenance work. A hot engine can cause burns. Wear protective gloves! The spark plug (Order No. 965 603 021) must be replaced in case of damage to the insulator, electrode erosion (burn) or if the electrodes are very dirty or oily. Remove the Þlter cover and hood. See Cleaning / changing the air Þlter. Pull the plug cap (7) off the spark plug.
Replacing the starter cable 14 18 15 Remove four screws (14). Remove starter housing (15). Insert a small screwdriver through the cooling slits on the back of the starter housing. Push aside the tabs (16) slightly and carefully remove the air guide (17) from the starter housing (15). Proceed in the order (A - B - C - D). 16 If replacing a starter cable that has not come apart, it will Þrst be necessary to de-tension the return spring on the cable drum.
Replacing the return spring Remove the starter housing (see “Replacing the starter cable”). Take the air guide off the starter housing (see “Replacing the starter cable”). De-tension the return spring on the cable drum (see “Replacing the starter cable”). Take off circlip (1) (circlip pliers, see “Accessories”). 5 Remove the cable pulley (2). Evenly lever the return spring (4) out of the catch using a screwdriver or similar tool.
Cutting attachment in central / side position NOTE: The Power Cut is delivered with the cutting attachment mounted in the middle position (1). For cutting up against obstacles, such as curbs or walls, the cutting attachment can be mounted to one side (2). Use this position only when actually necessary, and afterwards return the cutting attachment to the middle position In this position the Power Cut has better balance, is easier to guide, and is not as fatiguing for the operator.
Press the cutting attachment (13) onto the drive arm in the side position. Guide the V-belt (14) over the V-belt pulley (15). NOTE: The illustration shows the V-belt for models EK7300, EK7301. 13 Put the guard plate (16) on. 15 14 18 Screw on nuts (17) and tighten by hand. To tighten the V-belt see ”Tightening the V-belt / Checking Vbelt tension”. Screw in and tighten the screw (detail X, only for EK8100). Tighten the nuts (17) Þrmly with the combination wrench. Replace the grip (18) as shown.
