CHAPTER
I
TROUBLE SHOOTING
1. Worn or broken belts
A. Check pulley alignment
B. Belt fingers not set within
1/16 1/8 of belt
when the drive
belt is
engaged
C. Idlers loose or frozen up due
to lack
of
lubrication
D. Substitute belts used
E. Loose pulleys
F. Loose or broken idler spring
G. Belt cover removed from
unit
H. Auger or impeller jammed
2. Augers won't turn
A.
Auger shear pins broken
Note: Do not use substitute shear pins. These
are special pins that will break when items
other than snow are jammed into the augers.
Substitute pins may be too hard and dam-
age may result to the augers or auger gear
case
B.
Worn or broken belt
C.
Internal damage to auger gear case
D. Sheared roll pin-auger
pulley
A. Worn or
broken belt
B. Check traction lever adjustment
C. Check friction disk
D. Check wheel drive gear case
E. Wheel pins broken or missing
F. Idler spring off or broken
3. Unit doesn't move
CHAPTER II
ADJUSTMENTS
CLUTCH ROD
Place shift lever in the neutral (N) position. Attach
lower end of control rod into center hole of shift arm
and secure with spring clip (Fig. 1). Try pushing
Snow Thrower
forward and backward. Wheels
should turn. Pull shift lever back into the reverse
(R) position and put shift lever into the forward (F)
position to see
if these positions are approximately
the
same distance from the neutral (N) position. If
they are, no further adjustment should be required.
I f reverse is further away from neutral than for-
Fig. 1
ward, move lower end of control rod down one hole
in shift arm. If forward is further away from neutral
than reverse, move lower end of control rod up one
hole in shift arm
Place shift lever in the neutral
(N) position and
start engine. Keep hands and feet away from auger
and chute, and be certain the auger clutch is in the
"off" position. Try forward and reverse positions to
make sure the traction shift lever is properly ad-
justed when your Snow Thrower is running;
if
not,
adjust again according to
the instructions above.
With shift lever in forward position unit should
move ahead; with shift lever in reverse position
unit should back up; and with shift lever in neutral
position unit should show no signs
of moving in
either direction. Stop engine before removing lower
end of control rod from shift arm or when making
any other adjustment.
SKID ADJUSTMENT
The skids (Fig.
2),
mounted on each side
of the
auger housing, adjust the distance the scraper blade
is raised above the ground surface. When removing
snow from a gravel or uneven surface, it is advisable
to keep the scraper blade as high above the surface
as possible to prevent possible damage to the auger.
On a, blacktop or concrete surface, keep the scraper
blade as close to the surface as possible. To adjust
skids, raise Snow Thrower a few inches off the
ground and loosen the nuts securing the skids to the
auger housing. Move skids
up
or
down to desired
position and tighten nuts securely. Adjust both skids
to the same height to keep the auger level.
BELT
ADJUSTMENT
Traction Drive and Impeller Drive. No adjustment
required. These belts have a spring loaded idler
which makes them self-adjusting. Periodically check
idler to be sure it
is
operating freely
and provid-
ing tension.
I f belts come off from pulleys
make sure that the-
pulleys are not loose and that the idler is not dis-
torted. Idler should hit squarely on the belts.
With drive engaged, belt fingers should be within
1/16" to 1/8" of belts.
