DRIVE BELT, MAN
7.5.1 Replacing the drive belt, Man
See fig. 18, 19.
1. Dismantle the auger belt as described above.
2. Remove the left wheel.
3. Remove the locking ring (C) from the swing plate shaft
(D). Pull out the shaft.
4. Remove the spring (H).
5. Replace the belt (I). NOTE! Only genuine STIGA belts
are to be used.
6. Check that the tension pulley (A) is in line with the belt
(I).
7. Reassemble the spring (H), shaft (D) and locking ring
(C).
8. Check that the underside of the disc drive plate (Q) is
situated between the marks (N). See fig. 24.
NOTE! If the machine still does not drive properly,
recheck the location of the disc drive plate (Q).
9. Reassemble all parts in the reverse order.
7.5.2 Adjustment of drive belt, Man
The belt has a spring-loaded tension pulley. Adjustment is
not required. If the belt slips, change it.
7.6
DRIVE BELT, HST
7.6.1 Replacing the drive belt, HST
See fig. 20, 21.
1. Dismantle the auger belt as described above.
2. Loosen the beltguides (J, L) at the motor pulley.
3. Work off the used belt and fit the new. NOTE! Only
genuine STIGA belts are to be used.
4. Assemble the belt guides (J, L) at the motor pulley.
Adjust the belt guide according to the instructions below.
5. Reassemble all parts in the reverse order.
6. Adjust the control wire as described further “7.7”.
7.6.2 Adjusting the drive belt, HST
1. Dismantle the belt cover (1) by loosing the screw (2). See
fig. 16.
2. Adjust the tension pulley (A in fig. 20) until a belt play of
about 45 mm. See fig. 23.
Do not overtighten the belt. This will damage the
belt and the bearings. Always check the belt
tension according to the instructions below before
using the machine.
3. Check the adjustment according to the instructions
below.
4. Reassemble the belt cover. See fig. 16.
7.6.3 Check the drive belt, HST
1. Disconnect the wheel locks.
2. Set the speed lever in the neutral position. Do not activate
the clutch lever.
3. Start the engine and move the speed lever slow forwards.
If the drive shafts rotate, the belt is too tight, and the
tension pulley (A in fig. 20) shall be loosened and moved
from the belt.
4. If the tension pulley was moved redo the adjustment and
the check as described above.
7.7
ADJUSTING THE CONTROL WIRES
When the belts are adjusted or replaced, the control wires
must also be checked/adjusted (see below).
7.7.1 Adjusting auger wire
1. Remove the ignition key.
2. Dismantle the belt cover (1) by loosing the screw (2). See
fig. 16.
3. Actuate the auger drive lever and observe the tension
pulley. When the auger lever is in its half way of
movement against the handle, the pulley movement shall
stop against the belt (the pulley is allowed to move a few
mm during the last half of movement of the lever). See
fig. 25.
4. If necessary, unhook the spring and adjust the wire at the
screw, connected to the spring. See fig. 26.
5. Reassamble all parts in the reverse order.
7.7.2 Adjusting drive wire, Man
1. Remove the ignition key.
2. Lift the snow thrower forward and rest in on the auger
housing.
3. Loosen the screws (3) and dismantle the bottom plate (2).
See fig. 15.
4. Actuate the auger drive lever and observe the friction
disc. When the auger lever is in its half way of movement
against the handle, the friction disc shall touch the
friction wheel. See fig. 28.
5. If necessary, unhook the wire at the adjusting plate and
replace the wire in a suitable hole. See fig. 27.
6. Reassamble all parts in the reverse order.
7.7.3 Adjusting drive wire, HST
The drive wire, HST has no adjustment. The clutch is
adjusted with the belt tensioning pulley. See “7.6.2”.
7.8
FRICTION WHEEL, MAN
If the snow thrower does not move forward/backward the
problem could be the driving belt, driving control wire or
friction wheel. Check the friction wheel as follows.
7.8.1 Checking the friction wheel
1. Remove the ignition key.
2. Lift the snow thrower forward and rest in on the auger
housing.
3. Loosen the screws (3) and dismantle the bottom plate (2).
See fig. 15.
3. Put the gear stick in neuitral position.
4. With the gear stick in the neutral position, the centre of
friction wheel shall correspond with the centre of the
friction disc. See fig. 29.
5. Adjustments are carried out as described below.
6. Reassemble in the reverse order.
7.8.2 Adjusting the friction wheel
1. Loosen the friction wheel linkage and set the friction
wheel until the measurement in position 4 above is
obtained.
2. If the friction wheel is heavy worn and adjustments
cannot be carried out satisfactorily, replace in accordance
with the following instructions.
3. Otherwise reassemble in the reverse order after adjusting.
