Lubrication
Every 10 Hours (Figure 14)
1. Lubricate the Zerk fittings (1) every ten
hours with a grease gun.
2. Each time a shear bolt is replaced, the auger

3. Lubricate all pivot points.
Every 25 Hours)
Chains
1. (Figure 1) Move the speed shift lever (6) to
first gear.
2. Remove the gas from the gas tank. Stand
the snow thrower up on the front end of the
auger housing (4).
WARNING: Drain the gasoline
outdoors, away from fire or flame.
3. (Figure 22) Loosen the bolts (3) on each
side of the bottom panel (2).
4. Remove the bottom panel (2).
5. (Figure 15) Lubricate the chains (5) with a
chain type lubricant.
6. Wipe the hexshaft and sprockets (6) with
5W30 motor oil.
NOTE: If grease or oil come in contact
with the disc drive plate (1) or the friction
wheel (3), damage can result. Clean off
any oil or grease with a alcohol base
solvent.
7. (Figure 22) Install the bottom panel (2).
8. Tighten the bolts (3) on each side of the
bottom panel (2).
Items Not To Lubricate (Figure 15)
1. Do not lubricate the hex shaft and
sprockets (6). All bearings and bushings are
lifetime lubricated. For storage, put a slight
amount of 5W−30 motor oil on a cloth and
wipe the hex shaft and sprockets (6) to
prevent rust.
2. If grease or oil comes in contact with the
disc drive plate (1) or the friction wheel
(3), the friction wheel (3) can be damaged.
Make sure to thoroughly clean the disc drive
plate (1) and the friction wheel (3).
CAUTION: Any greasing or oiling of the
above components can cause
contamination of the friction wheel (3). If
the disc drive plate (1) or the friction
wheel (3) become contaminated with
grease or oil, damage to the friction wheel
will result.
3. The auger gear case is lubricated at the
factory and does not require additional
lubrication. If for some reason the lubricant
leaks out, have the auger gear case checked
by a factory authorized service center.
