general Recommendations
1. Always observe safety rules when performing any maintenance.
2. The warranty on this snow thrower does not cover items that have
been subjected to operator abuse or negligence. To receive full
value from the warranty, operator must maintain the snow thrower
as instructed in this manual.
3. Periodically check all fasteners and hardware to make sure these
are tight.
WARNING: Before servicing, repairing, lubricating or
inspecting, disengage all controls and stop engine. Wait
until all moving parts have come to a complete stop.
Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the snow thrower are

Augers
CAUTION: NEVER replace the auger shear pins with anything
other than OEM replacement shear pins. Any damage to the
auger gearbox or other components, as a result of doing so, will
NOT be covered by your snow thrower's warranty.
WARNING: Always turn off the snowthrower's
engIne and remove the key prior to replacing shear
pins.
• The augers are secured to the spiral shaft with two shear pins and
cotter pins. If the auger should strike a foreign object or ice jam, the
snow thrower is designed so that the pins MAY shear.
• If the augers will not turn, check to see if the pins have sheared.
When replacing pins, spray an oil lubricant into shaft before insert-
ing new pins.
Lubrication
1. Lubricate pivot points on the auger control and drive control with a
light engine oil once a season. See Figure 9.
2. Lubricate the face of the auger idler bracket with a light weight cold
weather lubricant at least once a season. See Figure 9.
