2. Install spark plug onto spark plug cap.
3. Set the oil switch to the “ON” position. Ground the negative (—) electrode (i.e. threaded part) of the

generates, which is very dangerous.
■ Fire may be caused if fuel spilled around the spark plug, so make sure that you test after draining off
fuel completely.
■ Fuel inside cylinder will be burnt if the spark plug is near the hole, so please turn off the engine first.
Pull the recoil starter several times to release the unborn gas in the cylinder.
