CHANGING THE ENGINE OIL
See fi gure 13.
Engine oil should be changed after every 25 hours of use.
Change the oil while the engine oil is still warm, but not hot.
This allows the oil to drain quickly and completely.
1. Remove the oil fi ll cap/dipstick.
2. Tip mower onto its side and allow oil to drain from the oil
fi ll hole into an approved container.
3. Place mower upright and refi ll with oil.
NOTE: Used oil should be disposed of at an approved
disposal site. See your local oil retailer for more
information.
MAINTAINING THE SPARK PLUG
See fi gure 11.
The spark plug must be properly gapped and free of
deposits in order to ensure proper engine operation. To
check:
1. Remove spark plug boot.
2. Clean any dirt from around base of spark plug.
3. Remove spark plug using a 13/16 in. spark plug socket
(not provided).
4. Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE: If replacing, use the following recommended
plugs are Torch E7RTC is NGK BPR6HS.
5. Measure plug gap. The correct gap is 0.028 − 0.031 in.
To widen gap, if necessary, carefully bend the ground
(top) electrode. To lessen gap, gently tap ground
electrode on a hard surface.
6. Seat spark plug in position; thread in by hand to prevent
cross-threading.
7. Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn for
proper washer compression.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.
8. Reinstall spark plug boot.
MAINTAINING THE DRIVE GEAR
See fi gure 15.
To ensure smooth operation of wheels, the wheel assembly
should be cleaned before storage.
1. Remove the nut and wheel and set aside.
2. Remove dust cover, e-ring, washer, pins, and wheel
gear. Clean any dirt from these items and the end of
the drive shaft by wiping with a dry cloth. If necessary,
rubbing alcohol may be used to remove any stubborn
dirt.
WARNING
Do not lubricate any of the components of the wheel.
Lubrication may cause the wheel components to fail
during use, which could result in mower damage and/or
serious personal injury to the operator.
3. Reinstall wheel gear with the arrows facing the front
of the mower. Reinstall pins, washer, e-rings, and dust
cover.
4. Reinstall wheel and nut. Tighten nut to secure.
