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. – Set the engine level, remove oil cap (Fig. 1), and check to see whether or not there is oil in the range between the upper limit and lower limit marks of the oil pipe (Fig. 2). – Top up with oil to upper limit mark if oil is insufficient (oil level is close to lower limit mark) (Fig. 3).
● Do not replace oil with the engine in a tilted position. Note ● Filling with oil while engine is tilted leads to overfilling which causes oil contamination and/or white smoke. 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.
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 EM2650UH, EM2651UH NOTE: Be careful not to trap clothing, etc., in the buckle.
