Traction Control / Auger Control Lock
The cams on the ends of the control rods which
interlock the traction drive and auger drive controls
must be lubricated at least once a season or every 25
hours of operation. The cams can be accessed beneath
the handle panel. Use a multi-purpose automotive
grease.
Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
IMPORTANT:
When following instructions in separate
engine manual for draining oil, be sure to protect frame
to avoid oil dripping onto transmission parts.
SECTION 7: SERVICE
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.
Engine
Refer to the separate engine manual packed with your
unit for all engine related maintenance procedures.
Augers
• The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If you hit a hard
foreign object or ice jam, the snow thrower is
designed so that the bolts may shear.
Refer to Figure 13.
• If the augers will not turn, check to see if the bolts
have sheared. Replacement shear bolts and hex
lock nuts have been provided with the snow
thrower. When replacing bolts, spray an oil
lubricant into shaft before inserting new bolts.
IMPORTANT:
NEVER replace the auger shear bolts with
standard hex bolts. 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.
Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the
snow thrower are subject to wear. They should be
checked periodically and replaced when necessary. To
remove the skid shoes, proceed as follows:
• Remove the six carriage bolts, bell washers, and
hex nuts which attach them to the snow thrower.
• Reassemble new skid shoes with the six carriage
bolts, bell washers (cupped side goes against skid
shoes) and hex nuts. Make certain the skid shoes
are adjusted to be level.
To remove shave plate, remove the carriage bolts, bell
washers, and hex nuts which attach it to the snow
thrower housing. Reassemble new shave plate, making
sure heads of the carriage bolts are to the inside of the
housing. Tighten securely.
Belt Removal And Replacement
Auger Belt
• Remove the plastic belt cover by removing the two
self-tapping screws. See Figure 16.
• Drain the gasoline from the snow thrower.
Figure 16
• Tip the snow thrower forward so that it rests on its
auger housing and remove six self-tapping screws
from the frame cover underneath the snow thrower.
• Roll the belt off the engine pulley. See Figure 17.
Figure 17
• Unhook the idler spring from the hex bolt on the
auger housing. See Figure 18.
