2. Inspection and Adjustment
(4) Inspection and adjustment of governor lever and accelerator
The governor lever and accelerating devices
(accelerating lever, pedal, etc.) of the machine unit are
connected by an accelerating wire or rod. If the wire
becomes stretched or the connections loose, the
deviation in the position may result and make
operation unsafe. Check the wire periodically and
djust if necessary.
a
Do not strongly move the accelerating wire or
accelerating pedal. It may deform the governor lever
or stretch the wire to cause irregular engine speed
control.
Checking and adjusting procedure are as follows.
1) Check that the governor lever of the engine
makes uniform contact with the high idling and
low idling limiting bolt when the accelerating
devices is in the high idling speed or low idling
speed position.
2) If either the high or the low idling speed side does
not make contact with the limiting bolt, adjust the
accelerating wire.
Loosen the accelerating wire fixing nut and adjust
the wire to contact with the limitng bolt.
Never release the limiting bolts. It will impair the
safety and performance of the product and functions
and result in shorter engine life.
(5) Air cleaner cleaning and element replacement
B
eware of dirt from air blowing
Wear protective equipment such as goggles to protect your eyes when
blowing compressed air. Dust or flying debris can hurt eyes.
The engine performance is adversely affected when
the air cleaner element is clogged by dust. So
periodical cleaning after disassembly is needed.
1) Undo the clamps on the dust pan and remove the
dust pan.
2) Loosen the wing bolt on the element and pull out
