Handling Method
A. Fix the gear case firmly to the engine side so that it
is not affected by the large impact when the
motor starts.
Standard gap between the pinion and ring gear
is 3-5mm.
Use a wire of specified thickness and tighten it
firmly. Insufficient tightening causes larger
contact resistance and makes starting difficult.
B. Precautions for starting
a. Ensure battery is charging. Insufficient
charging will make starting more difficult.
b. After the engine has started, turn switch to
run mode.
c. When it is difficult to start the engine by the
starting switch, turning it frequently will
decrease the battery electricity. In such a
case, turn off the switch once and then keep
it on for about 10 seconds. Repeat this proce-
dure several times.
d. Never turn on the starting switch while the
engine is operating.
- Disassembly and Reassembly (Typical)
A. Remove the solenoid (magnetic switch).
B. Remove the dust cover and take out the E ring
and thrust washer, where fitted. Remove the
rear cover and brush holder.
