MOUNTING OF HANDLE CAUTION: Before doing any work on the Petrol Brushcutter, always stop the engine and pull the spark plug connector off the spark plug. Always wear protective gloves! CAUTION: Start the Petrol Brushcutter only after having assembled it completely. For machines with bike handle models – Loosen knob (1). (1) – Place handle (4) between handle clamp (2) and handle holder (3).
MOUNTING OF PROTECTOR To meet the applicable safety provisions, only the tool/ protector combinations as indicated in the table must be used. Be sure to use genuine MAKITA cutter blades or nylon cutting head. Protector for metal blades Metal blade – The cutter blade must be well polished, free of cracks or breakage. If the cutter blade hits against a stone during operation, stop the engine and check the blade immediately. – Polish or replace the cutter blade every three hours of operation.
MOUNTING OF CUTTER BLADE OR NYLON CUTTING HEAD Turn the machine upside down, and you can replace the cutter blade or nylon cutting head easily. – Insert the hex wrench through the hole in the gear case and rotate the receiver washer (4) until it is locked with the hex wrench. (4) Hex wrench – Loosen the nut (1) (left-hand thread) with the socket wrench and remove the nut (1), cup (2), and clamp washer (3).
BEFORE START OF OPERATION Inspection and refill of engine oil – Perform the following procedure, with the engine cooled down. – While keeping the engine level, remove the oil gauge, and confirm that the oil is filled within the upper and lower limit marks. When the oil is in short in such a way that the oil gauge touches the oil only by its tip, in particular with the oil gauge remaining inserted in the crankcase without screwing-in (Fig. 1), refill new oil near the port (Fig. 2).
Point 2 in Replacement of oil: “If oil spills out” – If oil spills out between the fuel tank and engine main unit, the oil is sucked into through the cooling air intake port, which will contaminate the engine. Be sure to wipe out spilt oil before start of operation. REFUELING Handling of fuel It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refueling must be performed in a sufficiently ventilated room or in the open air.
CORRECT HANDLING OF MACHINE Attachment of shoulder strap – Adjust the strap length so that the cutter blade will be kept parallel with the ground. Buckle For EBH252U, EBH253U NOTE: Be careful not to trap clothing, etc., in the buckle. EBH252U EBH253U Detachment For EBH252L, EBH253L – In an emergency, push the notches (1) at both sides, and you can detach the machine from you. Be extremely careful to maintain control of the machine at this time.
2) Set the I-O switch (1) to OPERATION. CLOSE 3) Choke lever Close the choke lever. Choke opening: – Full closing in cold or when the engine is cold. – Full or half opening in restart just after stop of operation. 4) Primer pump Continue to push the primer pump until fuel enters into the primer pump. (In general, fuel enters into the primer pump by 7 to 10 pushes.) If the primer pump is pushed excessively, an excess of gasoline returns to the fuel tank.
B: Startup after warm-up operation 1) Push the primer pump repeatedly. 2) Keep the throttle lever at the idling position. 3) Pull the recoil starter strongly. 4) If it is difficult to start the engine, open the throttle by about 1/3. Pay attention to the cutter blade which may rotate. Attention in Operation When the engine is operated upside down, white smoke may come out from the muffler.
NYLON CUTTING HEAD Most effective cutting area The nylon cutting head is a dual string trimmer head capable of both automatic and bump & feed mechanisms. The nylon cutting head will automatically feed out the proper length of nylon cord by the changes in centrifugal force caused by increasing or decreasing rpms. However, to cut soft grass more efficiently, bump the nylon cutting head against the ground to feed out extra cord as indicated under operation section.
– Align the protrusion on the underside of the cover with the slots of the eyelets. Then push cover firmly onto the housing to secure it. Cover Protrusion Slot of eyelet SERVICING INSTRUCTIONS CAUTION: Before doing any work on the Petrol Brushcutter, always stop the engine and pull the plug cap off the spark plug (see “checking the spark plug”).
3) Place waste or paper near the oil refill port. Waste or paper 4) Detach the oil gauge, and drain oil, tilting the main unit toward the oil refill port. Drain oil in a container for orderly disposal. 5) Keep the engine level, and feed new oil up to the edge of the oil refill port. In refill, use a lubricant refill container. 6) After refill, securely tighten the oil gauge. Insufficient tightening of the oil gauge will lead to oil leakage.
CHECKING THE SPARK PLUG – Only use the supplied universal wrench to remove or to install the spark plug. – The gap between the two electrodes of the spark plug should be 0.7 - 0.8 mm (0.028” - 0.032”). If the gap is too wide or too narrow, adjust it. If the spark plug is clogged or contaminated, clean it thoroughly or replace it. CAUTION: Never touch the spark plug connector while the engine is running (danger of high voltage electric shock). 0.7 mm - 0.8 mm (0.028” - 0.

Just after stopping the engine, it may still hot with possibility of burns, inflammability and fire. ATTENTION: W hen the machine is kept out of operation for a long time, drain up all fuel from the fuel tank and carburetor, and keep it at a dry and clean place.
