Checking and adding oil
1. Shut engine off. Unscrew oil fill
cap/dipstick (AM, Fig. 6-1) and wipe with
clean, lint-free cloth.
2. Re-insert and firmly screw dipstick
into oil fill tube (AL), then unscrew and
check oil level. Level should be between
FULL and ADD marks on dipstick. Add oil
as necessary.
NOTE: DO NOT overfill. Damage to
engine seals may result.
Changing oil
IMPORTANT: After the first two hours of
use, change engine oil.
After initial change, change oil every 25
hours of operation or at end of each
snowthrowing season.
1. To change engine oil, start and run
engine to operating temperature.
2. SHUT ENGINE OFF.
3. Fold a piece of cardboard approxi
mately 3" X 6" (7.5 X15 cm) in size length
wise into a shallow V-shape (see Fig. 6-2).
4. Loosen BUT DO NOT REMOVE engine
oil drain plug cap (AK, Fig. 6-1). Place
folded cardboard beneath drain as shov^/n
in Fig. 6-2.
5. Place a suitable container (minimum
capacity: 1 quart) underneath end of card
board to catch draining oil. Slowly,
unscrew oil drain plug cap. Allow oil to run
down cardboard and into container. After
oil stops draining, reinstall oil drain plug
cap.
6. Unscrew oil fill cap/dipstick and wipe
with a clean, lint-free cloth. Insert a clean
funnel into oil filler tube.
7. Add fresh, clean oil of correct type
(see engine owner's manual) through
funnel and into oil filler tube. Engine will
hold approximately 26 ounces of oil.
Check oil level.
NOTE: DO NOT overfill. Overfilling
engine may damage engine seals.
8. Wipe up oil spills and drips immedi
ately. Dispose of oil in accordance with local
regulations.
Spark Plug
Yearly or after every 100 hours of opera
tion, remove, clean and inspect spark plug.
Clean plug by scraping (don't wire brush
or sandblast) deposits and residue away.
Replace spark plug with new one of same
type (see engine owner's manual) if elec
trodes are pitted or burned or if porcelain
is cracked.
If your unit came equipped with a resistor-
type spark plug when new, always replace
with a resistor-type spark plug. Refer to
the engine owner's manual.
Before installing spark plug, set electrode
gap to 0.030" (0.80mm). See Fig. 6-3.
