eNGINe OIL CHANGING INSTruCTIONS
Drain the engine oil when th engine is warm . Warm oil drains
quickly and completely .
1 . Turn the fuel valve to the OFF position to reduce the
possibility of fuel leakage .
2. Place a suitable container next to the engine to catch the
used oil .
3 . Remove the oil filler cap/dipstick and drain the oil into the
container by tipping the engine toward the oil filler neck .
Please dispose of used motor oil in a manner that is
compatible with the envirionment . We suggest you take
used oil in a sealed container to your local recycling center or
service station for reclamation . Do not throw into the trash,
oust it on the ground, or pour it down a drain .

mark on the dipstick with the recommended oil .
running the engine with a low oil level
