MAINTENANCE INSTRUCTIONS
ENGINE LUBRICATION
CAUTION: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or adjusting any
part of your snow thrower.
1. Change oil in crankcase after first two hours of
operation:
(a) Place pan for collecting used oil at rear of unit,
and remove drain cap from drain pipe at rear
base of engine (Fig. 34).
FIG. 34
(b) Tilt snow thrower back and drain oil into pan.
(c) Replace drain cap.
2. Refill crankcase to "FULL" mark on dipstick (ap-
proximately 1 pint) with SAE. 5W-30 multi-grade
all weather oil (Fig. 13).
DO NOT OVERFILL.
3. Always check oil level before using unit, or after
every 5 hours of operation. Add oil as required to
bring level to "FULL" mark.
4. Change oil every 25 hours of operation, or once
a season, whichever comes first.
SPARK PLUG MAINTENANCE
1. Remove spark plug and inspect it each time oil is
changed. Electrodes should be kept clean and free
of carbon; accumulation of carbon or oil will reduce
engi ne efficiency.
2. Check the spark plug gap using a feeler gauge.

3. Before installing spark plug, lightly coat threads
with graphite grease to ensure easy removal of plug
in future.
4. To ensure easy starting and efficient engine per-
formance, replace spark plug at beginning of each
season. (Refer to engine parts list for correct re-
placement types).
NOTE: Just as your automobile needs professional
mechanical maintenance from time to time, so does
your air-cooled engine. Replacement of the spark plug
and ignition points is made necessary by normal use.
SNOW THROWER LUBRICATION
CAUTION: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or adjusting your
snow thrower.
1. After every 8 hours operation, lubricate the following
parts of your snow thrower with light machine oil
(S.A.E. 10 or 20):
(a) Transmission
control linkage.
(b) Discharge chute controls.
(c) Carburetor linkage on engine.
(d) Drive chains.
2. In addition, remove drive chains at end of each
season's use and immerse in light oil (S.A.E. 10
or 20). Allow chains to drain, then wipe dry with
cloth and re-assemble to unit.
3. At least once a season, apply a coating of chassis
grease between flange at base of discharge chute.
Greasing this area prohibits accumulation of ice
on chute bearing surface on chassis (Fig. 10). which
would prevent effective chute operation.
