Resharpening The Cutting Tool - Makita EM2500U Instruction Manual

– Run the engine for approximately one minute at a moderate speed before applying full throttle.
Note: – If the starter handle is pulled repeatedly when the choke lever remains at "
fuel intake.
– In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry the
electrode section of the spark plug.
Caution during operation:
If the throttle lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 min
higher speed than required and at an approximate speed of 6,000 - 8,000 min
Starting the warm engine
– Same as above, except without moving the choke lever (choke lever remains in the position "
STOPPING
– Release the throttle lever (4) fully, and when the engine rpm has lowered,
push the I-O switch (1) to "O" position the engine will now stop.
– Be aware that the cutting head may not stop immediately and allow it to slow
down fully.
ADJUSTMENT OF LOW-SPEED ROTATION (IDLING)
The cutter blade or the nylon cutting head should not run when the control lever is fully released. If necessary, adjust the idle rpm using the idle
adjusting screw.
Checking the Idling speed
– Idle speed should be set to 3,000 min
If necessary correct it by means of the idle screw (the blade or the nylon
cutting head must not turn when the engine is on idle).
Screwing in the screw (1) will cause an increase in the engine speed,
whereas backing off the screw will reduce the engine speed.
