Maintenance
The operation and component life of this machine
are very dependent on regular maintenance and
proper lubrication. The frequency of lubrication
recommended is based on normal conditions.
Severe or unusual conditions may determine actual
service requirements.
CAUTION:
Exercise all safety precautions before attempting
to service this equipment by securely blocking any
hydraulic controlled implement and use the
“Mandatory Shut-down Procedure” (section 1,
page 2).
•
After service has been performed, be sure to
restore all guards, shields, and covers to their
original positions.
•
Before working under any hydraulically
controlled implement, be certain it is securely
blocked!
•
Always wear safety goggles or glasses when
working on hydraulic systems to avoid eye
injury and never check for hydraulic leaks by
using your hand. If injured by escaping fluid,
consult a doctor at once! Serious reaction or
infection can occur if proper medical treatment
is not obtained immediately.
WARNING:
The driveline and components on these
snowblowers are set-up to run at 540 or 1000
RPM with shear bolts placed at the appropriate
connections to protect the equipment if it
becomes clogged and can not run. Refer to figure
1, items #1 & #2 for location of shear bolts.

Lubrication:
•
Never attempt to lubricate the snowblower
with the engine running. Always be sure to
exercise the “Mandatory Shut-down Procedure
(section 1, page 2).
•
Check oil levels at the beginning of each
season, before each use and every 25 hours of
operation thereafter. The gearbox should be
drained and refilled to a (1/2) half full level of
SAE 90 gear lubricant at the end of each
season.
•
When the snowblower gear case is overfilled,
oil will be forced out breather vent, and
possibly damage seals.
•
Lubricate the auger chain with heavy duty
lubricant every 4 hours of operation and after
each adjustment. Maintain approximately one
inch of deflection for proper adjustment.
•
Grease the PTO u-joints every 8 hours of
operation and separate the PTO halves to coat
sliding surfaces with oil every 24 hours of
operation.
•
Spout bands, gears and worm gears should be
kept greased at all times.
•
Grease all bearings every 25 hours.
WARNING:
Keep all guards, shields, and
decals in place
