ASSEMBLY OF ENGINE AND SHAFT CAUTION: Before doing any work on the brush cutter, always switch off the motor and pull the spark plug connector off the spark plug. Always wear protective gloves! CAUTION: Start the brush cutter only after having assembled it completely. – After checking the parts, fasten the drive shaft to the engine with four bolts M6 x 30 (1). (1) – Mount the stand by two screws M5 x 12 (2).
MOUNTING OFOF HANDLE For BH3600 MOUNTING HANDLE – Place the handle with the throttle lever on the handle holder on the right side (to be held by the right hand) and the other on the left side. – Fit the handle edge to the handle holder groove, and provisionally fix the upper side (3) of the handle holder by four bolts M5 x 25 (4). – Adjust the handle to an angle easy to manipulate, and tighten the bolt (4) uniformly on the right and left sides.
MOUNTING OF CONTROL CABLE – Remove the air cleaner cover. – Place the control cable (1) in the adjusting bolt (2), and shift the swivel (3) so that the cable will be put in the swivel groove. At this time, the round-hole side of the swivel will be oriented toward the inner wire end-metal fitting. – Release the swivel, and confirm that the inner wire-end metal fitting will be placed in the hole. – Mount the air cleaner cover.
MOUNTING OF PROTECTOR – 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. CAUTION: The appropriate protector must always be installed, for your own safety and in order to comply with accident-prevention regulations. Operation of the equipment without the guard being in place is not permitted.
MOUNTING OF CUTTER BLADE Turn the machine upside down, and you can replace the cutter blade 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. – Loosen the nut (1) (left-hand thread) with the socket wrench and remove the nut (1), cup (2), and clamp washer (3). (1) (2) (3) (4) Mounting of cutter blade With the hex wrench still in place.
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. Detachment – In an emergency, pull the release belt (1) strongly upward, and you can detach the machine from you. Be extremely careful to maintain control of the machine at this time. Do not allow the machine to be deflected toward you or anyone in the work vicinity.
3) 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. Carburettor Primer Pump 4) Recoil starter – Pull the start knob gently until it is hard to pull (compression point). Then, return the start knob, and pull it strongly. – Never pull the rope to the full.
STOPPING 1) Release the throttle lever (6) fully, and when the engine rpm has lowered, set the I-O switch (1) to STOP the engine will now stop. 2) Be aware that the cutting head may not stop immediately and allow it to slow down fully. STOP I-O switch (1) Throttle lever (6) ADJUSTMENT OF LOW-SPEED ROTATION (IDLING) When it is necessary to adjust the low-speed rotation (idling), perform it by the carburetor adjusting screw. CHECKUP OF LOW-SPEED ROTATION – Set the low-speed rotation to 3000min-1.
SERVICING INSTRUCTIONS CAUTION: Before doing any work on the brush cutter, always stop the engine and pull the plug cap off the spark plug (see “checking the spark plug”). Always wear protective gloves! To ensure a long service life and to avoid any damage to the equipment, the following servicing operations should be performed at regular intervals. Daily checkup and maintenance – Before operation, check the machine for loose screws or missing parts.
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. 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. POINTS ON OIL – Never discard replaced engine oil in garbage, earth or sewage ditch.
CLEANING OF AIR CLEANER DANGER: INFLAMMABLES STRICTLY PROHIBITED Interval of Cleaning and Inspection: Daily (every 10 operating hours) – Turn the choke lever to the full close side, and keep the carburetor off from dust or dirt. – Remove the air cleaner cover-fixing bolts. – Pull the cover lower side and detach the air cleaner cover. – If oil adheres to the element (sponge), squeeze it firmly.
CLEANING OF FUEL FILTER WARNING: INFLAMMABLES STRICTLY PROHIBITED Interval of Cleaning and Inspection: Monthly (every 50 operating hours) Fuel filter (1) Hose clamp Fuel pipe Suction head in the fuel tank – The fuel filler (1) of the suction head is used to filler the fuel required by the carburetor. – A periodical visual inspection of the fuel filter is to be conducted. For that purpose open the tank cap, use a wire hook and pull out the suction head through the tank opening.
STORAGE WARNING: When draining the fuel, be sure to stop the engine and confirm that the engine cools down. Just after stopping the engine, it may still hot with possibility of burns, inflammability and fire. ATTENTION: When 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.
