manufacturer of your mower. Using a blade not
approved by the manufacturer of your mower is
hazardous and could result in serious injury, damage
your mower, and void your warranty.
WARNING
Drain the fuel
fi
rst before tilting the mower to replace
the blade.
1. Stop the engine and disconnect the spark plug wire.
Allow blade to come to a complete stop.
2. Turn the mower on its side (carburetor facing up).
3. Wedge a block of wood between the blade and mower
deck to prevent the blade from turning.
4. Using a 9/16-in. wrench or socket (not provided), loosen
the blade bolt by turning the bolt in a counterclockwise
direction as viewed from the bottom of the mower.
5. Remove the blade bolt, lock washer,

on the shaft. Finger tighten the bolt by turning in a
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.

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

gure 9.
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.

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
