CLEANING OF FUEL FILTER
API
WARNING:
• Shut off the engine. Keep away from open flames. Do
not smoke.
Interval of Cleaning and Inspection: Monthly (every 50
operating hours)
The fuel filter is used to filter the fuel required by the car-
buretor. A periodical visual inspection of the fuel filter is
to be conducted.
1. Open the fuel tank cap, use a wire hook and pull out
the suction head through the tank opening.
2. Remove the hose clamp and pull out the fuel filter
from fuel pipe.
3. Wash the fuel filter with kerosene.
4. After washing, reassemble it.
5. If the filter is hard or clogged up, replace it with new
one.
Replace the fuel filter at least quarterly to ensure an
enough fuel supply to the carburetor. Otherwise an insuf-
ficient fuel supply may cause the engine start failure and
limited maximum speed.
After checking, cleaning or replacing, fix the fuel filter
onto the fuel pipe with the hose clamp.
Push the fuel filter in all the way to the bottom of the fuel
tank. (Fig. 13)
REPLACEMENT OF FUEL PIPE (Fig. 14)
WARNING:
• Shut off the engine. Keep away from open flames.
Interval of Cleaning and Inspection: Daily (every 10
operating hours)
Replacement: Annually (every 200 operating hours)
Replace the fuel pipe every year, regardless of operating
frequency. Fuel leakage may lead to fire.
If any leakage is detected during inspection, replace the
fuel pipe immediately.
INSPECTION OF BOLTS, NUTS AND SCREWS
– Retighten loose bolts, nuts, etc.
– Check the fuel cap and oil cap for tightness. Check for
fuel and oil leakage.
– Replace damaged parts with new ones for safety
operation.
CLEANING OF PARTS
– Always keep the 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 piston seizure.
