Cleaning the Engine
Never clean the engine when it is running! Never clean with a bucket of water or a hose. Water
can get inside the working parts of the engine and cause a short circuit or corrosion.
Always try to use the engine in a cool, dry place. If the engine becomes dirty, clean the exterior
with a damp cloth, a soft brush, vacuum or pressurized air.
Checking the Oil
Check the oil level of the engine according to the Recommended Maintenance Schedule in Figure
7. The engine is equipped with an automatic shutoff to protect it from running with low oil
pressure. The engine should be checked before each use for proper oil level. This is a critical step
for proper engine starting.
To check or add oil, follow these steps:
1. Make sure the engine is on a level surface. Clean around oil fill.
2. Remove the oil filler/dipstick cap and check oil level.
