FUEL CAP
WARNING
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable filter and a
check valve. A clogged fuel cap will cause poor engine
performance. If performance improves when the fuel cap
is loosened, check valve may be faulty or clogged. Replace
fuel cap if required.
CHANGING THE ENGINE OIL
See figure 12.
Ensure the fuel tank is completely empty before tipping the
unit over otherwise fuel will leak out.
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 fill cap/dipstick.
2. Tip mower onto its side and allow oil to drain from the oil
fill hole into an approved container.
3. Place mower upright and refill with oil following the
instructions in the Adding/Checking Oil section.
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 figure 13.
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 LG F7RTC or LD F7RTC.
5. Measure plug gap. The correct gap is 0.71 mm -
0.79 mm. 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 figure 14.
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.
REPLACING THE WHEELS
See figure 15.
WARNING
Only use replacement wheels approved by the
manufacturer of your mower. Using wheels not approved
by the manufacturer of your mower is hazardous and
could result in serious personal injury.
1. Stop the engine and disconnect the spark plug wire.
Allow blade to come to a complete stop.
2. Remove the hub cap.
3. Remove the nut from the wheel axle, then remove the
wheel.
4. Replace with new wheel and reinstall nut to secure.
