PROBLEM
POSSIBLE CAUSES
CORRECTIVE ACTION
Auger stops turning.
Nylon shear pin is probably broken. Replace shear pin (for identification, see
parts list "Snowblower").
The reduction chain is broken or the
connecting link is unlocked.
Remove both chain guards. Inspect & repair
chain if needed (for identification, see parts
list "Snowblower").
Fan stops turning.
Shear bolt is probably broken.
Replace shear bolt (for identification, see
parts list "Snowblower").
Snowblower stops turning. One of the two belts is probably
damaged or broken.
Check both belts and replace damaged belt
(s) (for instructions, see belt replacement in
Maintenance section).
Belt has burn marks in
specific places.
Lack of tension on belt.
Snowblower engaged when
plugged.
Adjust manual clutch cable or replace springs
if stretched.
To obtain the proper tension, the distance
between the coils of the spring should
be .25’’ (1/4’’).
If not, remove the bolt, sleeve and the spring
from the original hole and reinstall them in the
second hole. (See Maintenance section, Belt
installation, adjustment and replacement).
Make sure the auger & the fan are not frozen
or plugged before engaging.
Height when snowblower is raised
Should not exceed 4 inches off ground. Make
adjustment as per instructions in owner’s
manual.
Belt snapping, shredding
or burning
Not original shear bolts
Use original shear bolts
Not original belts
Always use original belts. See parts
breakdown in subframe/drive mechanism
manual for part number.
Imperfections in pulleys
Verify that pulleys are smooth, have no rust
spots or weld burrs. Sand down pulleys or
replace.
Interference
Make sure that belt does not come into
contact with any other part, bolts, guides
etc... when engaged.
Improper tension
Make proper adjustment, verify if springs are
stretched from use, if so, replace springs.
Check in which hole on the tension arm of the
snowblower, the spring is installed. There is
too much tension.
Belt has flipped on its side
When installing new belt, have snowblower
run under supervision for a few minutes. Turn
everything off and verify that belt has not
turned on its side. If so, remove belt and re-
install in opposite fashion to rectify the bad
twist the belt has taken.
