Fuel Filter
WARNINg
Gasoline and its vapors are extremely flammable and explosive. Fire
or explosion can cause severe burns or death.
• Keep gasoline away from sparks, open flames, pilot lights, heat,
and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks
or leaks. Replace if necessary. See a Sears or other qualified
service dealer to replace fuel line.
• Before replacing the fuel filter, drain the fuel tank or close the fuel
shut-off valve.
• Replacement parts must be the same and installed in the same
position as the original parts.
• If fuel spills, wait until it evaporates before starting engine.
To Drain the Fuel:
1. Locate the fuel filter, which is routed on the left side of the engine
between the fuel tank and the carburetor, and may be attached to
the engine with a tie strap.
2. Cut the tie strap, if present, then pinch the in-line clamp on the
fuel filter with a pair of pliers.
3. Slide the clamp up the fuel line.
4. Remove the in-line fuel line and drain the fuel into an approved
container.
To Replace the Fuel Filter:
1. Before replacing the fuel filter, drain the fuel tank or close the fuel
shut-off valve. Otherwise, fuel can leak out and cause a fire or
explosion.
2. Use pliers to squeeze tabs on the clamps, then slide the clamps
away from the fuel filter. Twist and pull the fuel lines off of the fuel
filter. See Figure 23.
3. Check the fuel lines for cracks or leaks. Replace if necessary.
4. Replace the fuel filter with an original equipment replacement
filter.
5. Secure the fuel lines with the clamps.

Muffler
Temperature of muffler and nearby engine areas may exceed 150˚ F
(65˚C). Avoid contact with these areas.
Inspect muffler periodically, and replace if necessary. Replacement
parts for the muffler must be the same and installed in the same
position as the original parts. See the Parts List manual included with
this tractor.
Clean Engine
Do not use water to clean engine parts. Water could contaminate fuel
system. Use a brush or dry cloth.
• Daily or before every use, clean grass, chaff or accumulated
debris from engine. Keep linkage, spring, and controls clean.
• Keep area around and behind muffler free of any combustible
debris.
• Keeping engine clean allows air movement around engine.
• Engine parts should be kept clean to reduce the risk of overheat-
ing and ignition of accumulated debris.
Carburetor Adjustment
The carburetor on this engine is not adjustable.
Hydrostatic Transmission
The hydrostatic transmission is sealed at the factory and is mainte-
nance-free. The fluid level cannot be checked and the fluid cannot be
changed.
battery
Battery posts, terminals, and related accessories contain lead and
lead compounds, chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after handling.
The battery is sealed and is maintenance-free. Acid levels cannot be
checked and fluid can not be added.
• Always keep the battery cables and terminals clean and free of
corrosive build-up.
• After cleaning the battery and terminals, apply a light coat of
petroleum jelly or grease to both terminals.
If removing the battery for cleaning, disconnect the NEGATIVE
(Black) wire from its terminal first, followed by the POSITIVE (Red)
wire. When re-installing the battery, always connect the POSITIVE
(Red) wire to its terminal first, followed by the NEGATIVE (Black)
wire. Be certain that the wires are connected to the correct terminals;
reversing them could result in serious damage to your engine's
alternating system.
