Check and clean the spark plug daily or every 8 operating hours.
- Only use the supplied universal wrench to remove or install the spark plug.
- The gap between the two electrodes of the spark plug should be 0.7 to
0.8 mm. If the gap is too wide or too narrow, adjust it. If the spark plug is
clogged with carbon or fouled, clean it thoroughly or replace it. Use an exact
replacement.

- Supply grease through the grease nipple every 50 operating hours. (Shell
Alvania No. 3 or equivalent)

Otherwise an insufficient grease supply will cause a machine trouble.
Cleaning the fuel filter (suction head in the fuel tank)
WARNING: Inflammables strictly prohibited

suction head through the tank opening.
Replace the felt filter if it has hardened, been contaminated or be clogged.

carburetor. Otherwise an insufficient fuel supply will cause the engine start
failure and limited maximum speed.
Replacing the fuel pipe

Check and clean the fuel pipe daily or every 10 operating hours.
Replace the fuel pipe every 200 operating hours or every year regardless of
operating frequency. Otherwise fuel leakage may lead to fire.
If you find any leakage during inspection, replace the oil pipe immediately.
