Checking throttle valve
If the control cable is bent or caught, the throttle valve does not con-
tact with the idle adjusting screw, and it prevents the engine from
proper idling. In such a case, reposition the control cable to ensure
proper valve movement.

Inspecting bolts, nuts and screws and other parts
Retighten loose bolts, nuts, etc.
Check for fuel and oil leakage.
Replace damaged parts with new ones for safety operation.
Cleaning engine, cooling air inlet
Keep engine clean by wiping down with a cloth rag.
Keep the cylinder fins free of dust or dirt. Dust or dirt adhering to the
fins may cause engine overheat and piston seizure.
Blowing air is taken in from the air inlet vent. When airflow drops
down during operation, stop engine and inspect the air inlet vent for
any blockages. Clean it if necessary. Such a blockage may cause
overheat and damage the engine.
Replacing gaskets and packings
Replace gaskets and packings if the engine is disassembled.
Any maintenance of adjustment work that is not included and
described in this manual is only to be performed by Authorized
Service Agent.

WARNING:
When draining the fuel, stop the engine and
wait for the engine to cool down. Failure to do so may cause
burns or fire.
