Changing the Engine Oil

Change oil when the engine is warm. Refer to the oil specification
to select the proper grade for your operating environment.
1. Remove the oil drain bolt with a 12 mm socket
(not included) and extension.
2. Allow the oil to drain completely into an appropriate container.
3. Replace the oil drain bolt.
4. Add oil according to Add Engine Oil in Assembly section.
DO NOT OVERFILL. Oil not included for routine maintenance.
5. Dispose of used oil at an approved waste management
facility.

Once oil has been added, a visual check should show oil
about 1-2 threads from running out of the fill hole. If using the
dipstick to check oil level, DO NOT screw in the dipstick while
checking.
As a general rule of thumb the oil level is full when it can be
visually seen on the middle-top threads in the port, always fill
on flat level ground never tip to fill, over filling will damage the
engine and result in voiding any warranty.
