clockwise direction as viewed from the bottom of the
mower.
NOTE: Make certain all parts are replaced in the exact
order in which they were removed.
8. Torque the blade bolt down using a torque wrench (not
provided) to ensure the bolt is properly tightened.
9. The recommended torque for the blade bolt is 48–55
Nm (35–40 ft.lb.).
NOTE: We do not recommend sharpening the blade,
but if you do, be sure the blade is balanced before
reinstalling.
REPLACING THE WHEELS
See fi gure 14.
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.
CLEANING THE AIR FILTER
See fi gure 12.
For proper performance and long life, keep the air fi lter
clean.
1. Remove the air fi lter cover by pushing down the latch
while gently pulling out the cover.
2. Remove the air fi lter and clean it in warm soapy water.
Rinse and let dry completely.
3. Apply a light coat of engine oil to the air fi lter, then
squeeze it out using an absorbent cloth or paper towel.
4. Reinstall the air fi lter into the air fi lter base.
5. Replace and secure the air fi lter cover.
NOTE: The filter should be replaced annually for best
performance.
WARNING
A leaking fuel cap is a fi re hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable fi lter 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 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.
