CAUTION: Always stop engine before changing de-
flector position. Keep hands away from chute and
deflector when impeller is operating.
The type and depth of snow will also influence distance
snow can be thrown.
10. OPERATING ADJUSTMENTS
CAUTION: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or adjusting
your snow thrower.
DRIVE BELT
All V-Belts stretch a certain amount during normal
use. Consequently, the snow thrower drive belt will
probably require adjustment after the first five hours
of operation. Belt adjustment is required whenever the
primary clutch lever drops below the warning line on
the back plate.
NOTE: Failure to adjust drive belt as required will
result in excessive belt wear.
TO TIGHTEN DRIVE BELT
1. Remove four self-tap screws (G) and one locknut
(H),
and remove belt cover (Fig. 19).
FIG. 19
2. Loosen four bolts
(J)
securing back plate to engine
(Fig. 19).
3. Loosen four engine mounting bolts at base of engine,
(Fig. 14).
4. Engage primary clutch lever ("IN" position), and
move engine toward rear of unit until primary clutch
lever rests approximately
in the centre of slot (above
warning line).
5. Tighten engine bolt securely, making sure rear base
line of engine is in alignment with rear of chassis.
6. Check alignment of five holes in belt cover with four
holes in back plate (G), and bolt (H). Slide back
plate backwards or forwards until hole alignment
is obtained. Tighten four bolts
(J)
securing back
plate to engine.
7. Replace belt cover using four self-tap screws at
(G) and locknut at (H). Tighten securely.
SHIFT CONTROL ROD ADJUSTMENT
The "NEUTRAL" position of the snow thrower trans-
mission has a wide range and, in some cases, the
transmission may remain in "Forward" or "Reverse"
position when the shift control rod is moved into the
"Neutral" range at the handle plate. This may not
become apparent until used in heavy snow. If this
situation occurs, stop engine and proceed with the
following adjustments:
If your unit stays in "Forward" Drive position when
shift control rod is moved into neutral range, adjust
flange nuts at lower end of shift rod: (Fig. 5 to 8).
(a) Loosen upper flange nut.
(b) Tighten lower flange nut up toward transmission
control bracket one or two turns. This will, in
effect, shorten the shift control rod.
(c) Tighten upper flange nut down onto transmission
control bracket.
If your unit stays in "Reverse" drive when shift control
rod is returned to neutral range, adjust flange nuts on
lower shift control rod: .
(a) Loosen lower flange nut.
(b) Tighten
upper flange nut down onto transmission
control bracket one or two turns. This will, in
effect, lengthen the shift control rod.
(c) Tighten lower flange nut up against transmission
control bracket.
GROUND CLEARANCE ADJUSTMENT (Fig. 20)
Slots in skids provide adjustment up or down. To in-
crease or decrease ground clearance of impeller hous-
ing prop up front of unit using a piece of wood or
similar object and loosen two Ys -16 nuts on each skid.
Raise or lower the skids to desired height.
In icy or packed snow conditions, runners on skids
FIG. 20
may force the unit to ride on top of snow, preventing
effective snow removal. When this occurs, remove
skids and invert them so that knife edges of skids
will cut through snow.
CHAIN ADJUSTMENTS (Fig. 21)
Correct chain tension is of vital importance in obtain-
ing efficient performance. To obtain chain tension as
illustrated in Fig. 21, each chain should be adjusted
by following the steps below:
