Resharpening The Cutting Tool - Makita RBC413U Instruction Manual

Starting the warm engine
– As described above, except without moving the choke lever (choke lever remains in the down position).
Stopping
1) Release the throttle lever (2) 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.
OPERATION OF THROTTLE LEVER
With the throttle lever main unit held by hand (with the lock-off lever pushed), pull
the throttle lever to increase the engine rotation.
Release the throttle lever to let the engine run idle.
Release the hand from the throttle lever main unit. The lock-off lever returns
automatically so that the throttle lever is not pulled by mistake.
IDLE ADJUSTMENT
– Never attempt to make engine adjustments while the unit is running and strapped
to the operator. Always make engine adjustments with the unit resting on a flat,
clear surface.
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 Idle speed
– Idle speed should be set to 2,600 min
If necessary correct it by means of the idle adjustment screw (the blade or the
nylon cutting head must not turn when the engine is on idle.)
Turning in the screw clockwise will cause an increase in the engine speed,
whereas turning the screw counterclockwise will reduce the engine speed.
