To change oil and filter:

Route oil drain hose and valve through hole in base. See engine manual and engine maintenance label for oil/filter change in- formation.

To replace primary (canister) fuel filter:

Turn filter counterclockwise. Re- move filter.

Fill new filter with fresh fuel. Apply thin coat of fuel to gasket on new fil- ter. Install new filter and turn clock- wise.

Inspect fuel lines, and replace if cracked or worn.

To drain water from fuel system:

See engine manual.

To replace secondary (in-line) fuel filter:

Note direction of fuel flow as indi- cated by arrow on side of filter. Re- move fuel line clamps and discon- nect fuel lines from fuel filter. Re- place filter, reconnect fuel lines, and reinstall clamps.

To drain sludge from fuel tank:

! Beware of fire. Do not smoke and keep sparks and flames away from drained fuel. Dis- pose of drained fuel in an en- vironmentally-safe manner. Do not leave unit unattended while draining fuel tank.

! Properly lift unit and secure in a level position. Use ade- quate blocks or stands to support unit while draining fuel tank.
