POTENTIAL HAZARD
If gasoline is spilled on a hot engine, it
could ignite.
WHAT CAN HAPPEN
Contact with burning gasoline could cause
serious personal injury.
HOW TO AVOID THE HAZARD
Drain gasoline from a cold engine only.
2. Remove cap from fuel tank (Fig. 6) and use
pump-type syphon to drain fuel into clean gas
can.
Note: This is the only procedure
recommended for draining fuel.

Change Engine Oil

Change oil after the first 5 operating hours and then
after every 50 hours or every season. Change oil
while engine is warm.
Note: Change oil every 25 hours when
operating under heavy load or in high
temperatures.
POTENTIAL HAZARD
Tipping mower may cause fuel leakage
from carburetor or fuel tank.
WHAT CAN HAPPEN
Gasoline is extremely flammable, highly
explosive and under certain conditions can
cause personal injury or property damage.
HOW TO AVOID THE HAZARD
Avoid fuel spills by running engine dry or
remove gas with hand pump, never siphon.
1. Stop engine and pull wire off spark plug (Fig. 8).
2. Drain gasoline from fuel tank. See Drain
Gasoline section.
Note: The oil should be warm before
draining. Warm oil flows better and
carries more contaminants than cold
oil.
3. Even though the gasoline has been drained from
the engine, enough fuel should be left in the
carburetor bowl and fuel line to start the engine.
Reinstall the spark plug wire onto the spark
plug. Start the engine and let it run until it runs
out of fuel. Briefly running the engine will warm
up the oil.
4. Pull wire off spark plug.
5. Remove dipstick from oil fill tube and place a
drain pan next to left side of mower.
6. Tip mower on left side.
7. Drain oil from oil fill tube at dipstick (Fig. 17).
Drain oil into appropriate container. Dispose of
oil properly. Recycle per local codes.
8. Turn mower upright.
9. Fill crankcase to FULL line on dipstick with
fresh oil. See Before Starting chapter, Oil section
for specifications.
10. Check oil level and reinstall dipstick.
11. Wipe up any spilled oil.

Spark Plug

A spark plug that is dirty, pitted, carbon-covered or
has worn electrodes may cause hard starting and poor
operation.
Remove plug after every 25 operating hours and
check its condition. Replace spark plug every 100
operating hours or every season. Use a Champion
RC12YC spark plug or equivalent.
1. Stop engine and pull wire off spark plug (Fig. 8).
2. Remove spark plug and clean with a wire brush,
removing carbon build-up. DO NOT SAND
BLAST. Check condition of plug for cracks and
damaged or worn electrodes. Replace if
necessary.
