Engine
Refer to the separate engine manual packed with your
unit for all engine maintenance procedures.
Augers/Shear Bolts
The augers are secured to the auger shaft with two
shear bolts and hex lock nuts. Refer to Figure 14. If you
hit a foreign object or ice jam, the snow thrower is
designed so that the bolts may shear.
If the augers will not turn, check to see if the bolts have
sheared. Two replacement shear bolts and hex lock
nuts have been provided with the snow thrower. For
future use, order kit number OEM-710-0890 which
contains four replacement shear bolts and
accompanying hex lock nuts.
NEVER replace the auger shear bolts with
IMPORTANT:
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 throwers warranty.
Grease Fittings
Disconnect the spark plug wire
Traction Control / Auger Control Lock
The cams on the ends of the control rods which
interlock the traction drive and auger drive levers 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.
Gear Case
The gear case is lubricated with grease at the factory.
Every 25 hours or once a season, remove the vent plug
located on the top of the gear case. If necessary, use a
grease gun on the gear case grease fitting. Lubricate
using Shell Alvania grease EPR00, part number 737-
0168. Refer to Figure 14.
Do not overfill the gear case. Damage to
IMPORTANT:
the seals could result. Be sure the vent plug is free of
grease in order to relieve pressure.
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.
Refer to Figure 6.
To remove the skid shoes, remove the six carriage
bolts, belleville washers and hex nuts (three on each
side) which attach them to the snow thrower.
Reassemble the new skid shoes making sure that the
bolts and washers are reinstalled correctly. Also, make
certain the skid shoes are adjusted so the flat surface is
sitting level on the ground. The skid shoes can be
rotated on this machine 180° so both flat surfaces of the
skid shoe can be utilized for wear.
To remove the shave plate, remove the carriage bolts,
belleville washers and hex nuts which attach it to the
snow thrower housing. Reassemble the new shave
plate, making sure the heads of the carriage bolts are to
the inside of the housing. Tighten securely.
