Important:
Do not clean the spark plug.
Always
replace the spark plug when it has a black coating,
worn electrodes, an oily film, or cracks.
2.
Check the gap between the center and side electrodes
(Figure 29) and bend the side electrode if the gap is
not correct.
Installing the Spark Plug
1.
Install the spark plug and metal washer. Ensure that
the air gap is set correctly.
2.
Tighten the spark plug to 15 ft-lb (20.4 N-m).

Maintenance
Draining the Fuel Tank
Drain the fuel tank when you will not be using the machine
for more than 30 days.
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.
2.
Disengage the blades (PTO).
3.
Set the parking brake.
4.
Stop the engine and wait for all moving parts to stop.
5.
Remove the ignition key.
6.
Open the hood.
7.
Squeeze the ends of the hose clamp together and slide
it up the fuel line toward the fuel tank (Figure 30).
