3. Lift cover off. Clean cover thoroughly.
4. Carefully remove preĆcleaner. If preĆcleaner is dirty,
carefully wash it in a solution of liquid soap and warm
water. Rinse in clear water. Allow to dry thoroughly
before using.
5. If paper cartridge is dirty, clean the paper filter by
tapping it gently on a flat surface. If very dirty,
replace cartridge.
IMPORTANT: Do not oil pre-cleaner or paper
cartridge. Do not use pressurized air to clean
paper cartridge.
6.
Reinstall preĆcleaner over paper cartridge.
Reinstall air cleaner cover and tighten securely in
place with two (2) knobs.
IMPORTANT: Do not operate engine without air
cleaner element otherwise extreme engine wear
and damage will likely result.
REPLACING SPARK PLUG
Use a CHAMPION RC12YC spark plug or equivalent.
Correct air gap is 0.5 mm (0.020"). Remove plug after
every 25 operating hours and check its condition.
1. Stop engine and wait for it to cool. Pull wire off
spark plug (Fig. 10).
2. Clean around spark plug and remove plug from
cylinder head.
IMPORTANT: Replace a cracked, fouled, or dirty
spark plug. Do not sand blast, scrape, or clean
electrodes because engine damage could result
from grit entering cylinder.
3.
Set air gap at 0.5 mm (0.020") (Fig. 21). Install
correctly gapped spark plug and gasket seal. Tighten
plug firmly to 19 N m (14 ft-lb).

DRAINING GASOLINE
1. Stop engine and wait for engine to cool. Pull wire
off spark plug (Fig. 10).
Note: Drain gasoline from a cold engine only.
2. Remove cap from fuel tank and use pump-type
syphon to drain fuel into clean gas can.
Note: This is the only procedure recommended for
draining fuel.
CHANGING CRANKCASE OIL
Change oil after the first 5 operating hours and after
every 50 hours thereafter. Since warm oil drains
better and carries more contaminants than cold, run
engine for several minutes before draining oil.
1. Drain gasoline. Refer to Draining Gasoline section.
2. Run engine until it dies. Try starting engine once
more to make sure gas is out of carburetor.
3. Pull wire off spark plug (Fig. 10).
4. Lift discharge door and remove grass bag. Drain
gasoline from fuel tank: refer to Draining Gasoline,
page 15.
5. Remove dipstick from oil fill tube and place a drain
pan next to left side of mower.
6. Tip mower on its left side, allowing oil to drain into
drain pan (Fig. 22).
7. When oil is drained, return mower to upright
position and add fresh oil to engine. Refer to Fill
Crankcase With Oil, page 7.
