Installing the Spark Plug
1. Install the spark plug and metal washer. Make sure that
the air gap is set correctly.
2. Tighten the spark plug to 15 ft.-lb. (20 N
⋅
m).
3. Push the wire onto the spark plug (Fig. 24).
4. Close the hood.
Checking the Tire Pressure
Maintain the air pressure in the front and rear tires at 20 psi
(138 kPa). Check the pressure at the valve stem after every
25 operating hours or yearly, whichever occurs first
(Fig. 26). Check the tires when they are cold to get the most
accurate pressure reading.

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 so that the left front side is slightly
lower than the right side to ensure that the fuel tank
drains completely. Then disengage the PTO, set the
parking brake, stop the engine, and remove the ignition
key.
2. Open the hood and locate the fuel filter (Fig. 27).
3. Squeeze the ends of the hose clamp together and slide it
up the fuel line toward the fuel tank (Fig. 27).
4. Pull the fuel line off of the filter (Fig. 27) and allow
gasoline to drain into a gas can or drain pan.
Note: Now is the best time to install a new fuel filter
because the fuel tank is empty.
5. Install the fuel line onto the filter. Slide the hose clamp
close to the filter to secure the fuel line and filter.
