when the clutch lever is up (= disengaged).If it does, 
contact an authorised service station. 
8.6 FRICTION WHEEL

8.7 DIFFERENTIAL (SN 1129)
8.7.1 Description
In the differential the drive force is transferred from the chain 
drive to the right and left shafts via two free wheels, one for 
each shaft.
This means that the outer wheel can rotate faster than the in-
ner wheel on bends.
With the differential the snow thrower is as easy to drive 
around bends as straight forward.
The differential also makes the snow thrower easier to handle 
on hard surfaces, for example in the garage or in the store.
8.7.2 Replacing the differential (SN 1129)
See fig. 31.
The differential (A) is replaced according to the following 
instructions:
1.  Lift the snow thrower forward and rest in on the auger 
housing.
2. Disassemble the wheels.
3. Loosen the screws (3) and dismantle the bottom plate (2). 
See fig. 20.
4. Disassemble the bearing housings (B) with bearings at 
both sides.
5. Loosen the intermediate shaft (C) by disassembling the 
bearing screws (D) at both sides.
6. Slacken the chain tension by loosening the support 
bearing attachment (E). The support bearing attachment 
is loosened by disassembling the two screws at the top.
7. Remove the chain from the differential.
8. Pull out the shafts from the differential and remove the 
differential.
9. Check the chains. Replace if required. The chains shall 
not be lubricated. They are factory lubricated. Excessive 
grease can spoil the friction if it reach the friction wheel 
or the friction disc.10. Check the bearings for dissonance and uneven friction at 
rotation. Replace if required.
11. Reassemble all parts in the reverse order.
8.8 REPLACING THE SHEAR BOLTS 
The auger is fastened to the shaft by special bolts (20 in fig. 
14) that are designed to break if something gets stuck in the 
auger housing.
Always use genuine spare parts. Other types of 
bolts could cause serious damage to the machine.
1.  Stop the engine.
2.  Disconnect the starting cable from the spark plug.
3.  Ensure all the rotating parts have stopped.
4.  Remove the object that has fastened in the auger.
5.  Lubricate the auger shaft (see above).
6. Align the holes in the shaft and the auger.
7. Remove the defective bolt parts.
8.  Assemble the new genuine bolt.
8.9 ADJUSTMENT THE DRIVING BANDS
Valid for SNT 929, SNT 1129, see figur 27
If the machine is driven unevenly or if the driving bands slip, 
these shall be checked/adjusted as follows:
1. Lift the band in the middle.
2. Measure the distance between the driving band and the 
upper part of the support plate. The distance shall be 30 
mm. 
3. If necessary, adjust at the screw (3).
8.10 HEADLAMP BULB
Only 27 W original spare part bulb is allowed to be 
used. Bulbs with higher power will damage the 
headlamp.
The headlamp bulb is fitted to the headlamp by a bayonet 
socket. See fig. 32. To replace the bulb proceed as follows:
1. Turn the bulb about 30° CCW and pull it out.
2. Release the plastic locks at each side of the bulb and pull 
off the cable connection from the bulb.
3. Fit the new bulb in the reverse order.

9 STORAGE
Never store the snow thrower with petrol in the 
tank in a confined area with bad ventilation. Petrol 
fumes could reach open flames, sparks, cigarettes 
etc.
If the snow thrower is to be stored for a longer period than 30 
days, the following measures are recommended:
1.  Empty the petrol tank.
2.  Start the engine and let it run until it stops due to lack of 
fuel.
Empty the petrol tank outdoors when the engine is 
cold. Do not smoke. Empty into a container 
designed for petrol.
3.  Change the engine oil if it has not been done for 3 
months.
4.  Remove the spark plug and empty a little engine oil 
(about 30ml) in the hole. Crank the engine a couple of 
times. Screw back the spark plug.
5.  Clean the whole snow thrower thoroughly.
6.  Lubricate all the parts as shown in LUBRICATING 
above.
7.  Inspect the snow thrower for damage. Repair if 
necessary.
8.  Touch up any paint damage.
9.  Rust protect the metal surfaces.
10. Store the snow thrower indoors if possible. 
10 IF SOMETHING BREAKS
