WARNING
After connecting the engine to the working machine and arranging the wire, unfasten the lock
nut, and adjust the play on the throttle wire at 0.5 to 1.0 mm using the adjusting screw. Re-
tighten the lock nut.
Unless sufficient play is retained, the working machine may fail to stop even if the throttle
lever is returned.

Consult your dealer when it is necessary to adjust the low-speed revolution.
If the low-speed revolution is increased too much, the main unit may fail
to stop even if the throttle lever is returned.
• A larger play on the throttle wire could cause starting trouble.
• A larger play on the throttle wire could cause unexpected increase in the
revolution speed if the wire runs out the guide accidentally.
