After every 100 hours running, the fuel tank and filter strainer must be cleaned. Open the fuel tank cover, take out the filter
strainer and clean it with brush. Take off the fuel tank, clean inside of the tank and remove the dirt and water attached on the
internal surface of the tank. Reassemble the tank and fit the strainer, then fill in new fuel oil till the oil level reaching the red
basic line.
After running every two years, check the ageing condition of the oil tube. If there is any ageing, hardening or crack, it must be
replaced. Tighten the replaced oil tube joints and check its leakage.
Maintenance before stopping use for long time
For some reasons, if the engine is not used for a long time, it must be maintained one time before is stored: A Take off the
fuel tank, drain out all fuel and clean the dirt and water inside of the tank. Open th fuel cock, unscrew the drain plug at the
bottom of carburettor, drain out fuel in carburettor thoroughly, and then, screw the drain plug to original position. B Unscrew
the drain plug at the bottom of the crankcase and drain out the lubrication oil in crankcase thoroughly, then tighten the drain
plug. C Clean the outer surface of the gasoline engine with clean cotton, remove the dirt and dust etc., then store the gaso-
line engine in a clean and dry place where is in good ventilation condition. D Turn crankshaft and make the gasoline piston
stopping at upper limit position in order to avoid ai entering in. Disposing wasted oil: Pleas use a special container to collect
wasted oil from gasoline engine and send to local wasted oil station for disposing. Don’t pour everywhere.
Transportation & Storage
Lightly handle in the loading and unloading, keep upright and don’t incline. Strictly prohibit bumping and protect from
drenching in the transportation. The gasoline engine should be stored in the clean, ventilating, moisture-proof and damp-
proof place. If storing the engine for a long time:
1. Store the gasoline engine in the clean, ventilating, moisture-proof and damp-proof place.
2. Drain the fuel completely out of the machine (including machine oil in the oil bath type air cleaner).
