1. Preparations before ground drilling start-up

Check the oil level of the engine, place the engine in a horizontal position, and clean around the filling port. Remove the oil ruler, wipe the oil with a clean cloth, then pierce it from the bottom of the oil, take the oil ruler again, and check the scale of the oil ruler. If the oil level is too low, the oil should be increased, always increasing to the upper marking in the dipstick. Note: Low oil level will cause engine trouble, but oil level should not exceed the upper scale, too much oil will cause power decline and smoke.

Check whether the filter element of the air filter is blocked or not. If necessary, it must be maintained. Note: Never use the engine without air filter, otherwise, it will speed up engine wear. Check the fuel tank, you must use pure gasoline.

2. Drilling and extinguishing

When the engine starts, the fuel switch should be pulled to the opening position, and the choke valve switch should be pulled to the choke valve position. Note: If the engine is in the heat engine or the air temperature is high, do not use the choke valve, should be the throttle azimuth pulled to the fast azimuth to start. When starting, the starting rope will be pulled out gently until resistance is felt and then pulled agilely. Move the throttle to the stop position, then turn the fuel switch to the close position.
