1. Stop the engine and disconnect the spark plug wire.
Allow the blade to come to a complete stop.
2. Turn the product on its side (air fi lter facing up).
3. Wedge a block of wood between the blade and the
mower deck to prevent the blade from turning.
● Installing: See figure 12a.
● Removing: See figure 12b.
NOTE: Do not wedge the block of wood between the
blade and the plastic cover.
4. Using a 16 mm wrench or socket (not provided), loosen
the blade bolt by turning the bolt in a counterclockwise
direction as viewed from the bottom of the product.
5. Remove the blade bolt, spring washer, and blade.
6. Place the new blade on the shaft. Make sure it is
installed with the curved ends pointing up toward the
mower deck and not down toward the ground.
7. Replace the spring washer, and blade bolt on the shaft.
Finger tighten the bolt by turning in a clockwise direction
as viewed from the bottom of the product.
NOTE: Ensure 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 40–45
Nm.
NOTE: Do not sharpen the blades; replace with new
item. Blades need to be properly balanced to avoid
damage and personal injury.
CLEANING THE AIR FILTER
See figure 13.
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.
FUEL CAP
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 figure 14.
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 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 the product upright and refi ll 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 15.
The spark plug must be properly gapped and free of
deposits in order to ensure proper engine operation. To
check:
1. Remove the spark plug boot.
2. Clean any dirt from around base of the spark plug.
3. Remove the spark plug using a 13/16 in. spark plug
socket (not provided).
4. Inspect the spark plug for damage, and clean with a
wire brush before reinstalling. If the insulator is cracked
or chipped, spark plug should be replaced.
NOTE: Use the recommended E7RTC spark plug for
replacement.
5. Measure the plug gap. The correct gap is 0.71 mm -
0.79 mm. To widen the gap, if necessary, carefully bend
the ground (top) electrode. To lessen the gap, gently tap
the ground electrode on a hard surface.
6. Seat the spark plug in position; thread in by hand to
prevent cross-threading.
7. Tighten with wrench to compress the washer. If the
spark plug is new, use 1/2 turn to compress the washer
appropriate amount. If reusing an 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 the spark plug boot.
MAINTAINING THE DRIVE GEAR
See figure 16.
To ensure smooth operation of the wheels, the wheel
assembly should be cleaned before storage.
1. Remove the hub cap.
2. Remove the nut and the wheel and set aside.
3. Remove the dust cover, e-ring, washer, pins, and the
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.
