) on the side of the frame with light oil at least once a season.
Auger Bearings
Every season lubricate the auger bearings (

4. Avoid getting oil on the friction wheel rubber and aluminum drive plate.
Drive/Auger Control Lock
The cams on the ends of the control rods which interlock the drive and auger

SERVICING
WARNING:
Before servicing, repairing, or inspecting, disengage all clutch levers and stop
engine.
Wait until all moving parts have come to a complete stop.
Disconnect spark plug wire and ground it against the engine to prevent
unintended starting.
Always wear safety glasses during operation or while performing any
adjustments or repairs.
ENGINE
Refer to the separate engine manual packed with your unit for all engine
maintenance procedures.
AUGERS
The augers are secured to the spiral shaft with two shear pins (
a, fig.20
) and
cotter pins (
b,fig.20
). If you hit a hard foreign object or ice jam, the snowthrower
is designed so that the pins may shear.
If the augers will not turn, check to see if the pins have sheared. Replacement
shear pins and cotter pins have been provided with the snowthrower. When
replacing bolts, spray an oil lubricant into shaft before inserting new pins.
IMPORTANT: NEVER replace the auger shear pins with standard pins. Any
damage to the auger gearbox or other components as a result of doing so will
not be covered by your snowthrower’s warranty.
SHAVE PLATE AND SKID SHOES
The shave plate and skid shoes on the bottom of the snowthrower are subject to
wear. They should be checked periodically and replaced when necessary.
To remove skid shoes, remove four carriage bolts and flange lock nuts.
(S
ee fig.18
)
To remove the shave plate (
oo, fig.20
), remove the carriage bolts ( mm,
fig.20 ) and flange lock nuts ( nn, fig.20
) which attach the shave plate to the
snowthrower housing.
Reassemble the new shave plate, with heads of carriage bolts to the inside of
the housing. Tighten securely.
