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 8.
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 7.
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.
