Fuel Tank

Draining The Fuel Tank
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
1. Park the machine on a level surface, to assure fuel
tanks drain completely. Then disengage the power take
off (PTO), set the parking brake, and turn the ignition
key to "OFF" to stop the engine. Remove the key.
2. Close fuel shut-off valve (Fig. 44).
3. Loosen the hose clamp at the fuel filter and slide it up
the fuel line away from the fuel filter (Fig. 44).
4. Pull the fuel line off fuel filter (Fig. 44).
5. Open fuel shut-off valve for left and right tanks. Allow
gasoline to drain into a gas can or drain pan. (Fig. 44).
Note: Now is the best time to install a new fuel filter
because the fuel tank is empty.
6. Install the fuel line onto the fuel filter. Slide the hose
clamp close to the fuel filter to secure the fuel line
(Fig. 44).

Servicing the Spark Arrester

Inspect the spark arrester every 50 hours for damage, such
as holes in the screen, and for build-up on the screen. If it
is damaged, replace it with a new spark arrester. If it is
dirty, remove it and clean the screen with a wire brush
and/or soak it in solvent.

Greasing and Lubrication

Lubricate the machine when shown on the CHECK
SERVICE REFERENCE AID decal (Fig. 45). Grease
more frequently when operating conditions are extremely
dusty or sandy.
Grease with No. 2 general purpose lithium base or
molybdenum base grease.
How to Grease
1. Disengage the power take off (PTO) and turn the
ignition key to "OFF" to stop the engine. Remove the
key.
2. Clean the grease fittings with a rag. Make sure to
scrape any paint off the front of the fitting(s).
3. Connect a grease gun to the fitting. Pump grease into
the fittings until grease begins to ooze out of the
bearings.
4. Wipe up any excess grease.
Where to Add Grease
Lubricate the grease fittings as shown on the CHECK
SERVICE REFERENCE AID decal (Fig. 45).
