1. In order to prevent spillage, remove the fuel from
the tank by closing the fuel valve and running the
engine until it stops. Then, open the tank cover
and let the petrol completely drain into a suffi -
ciently large container by tilting the machine or
using a hand pump. Then, close tank cap again.
2. Remove the two screws that hold the belt cover
and place the cover to one side.
3. Remove the belt as follows:
• Unwind the feed screw belt from the engine
roller.
• Turn the tensioning roller to the right to reduce
the tension.
• Lift the belt from the engine roller.
4. Carefully turn the snowblower up and forward so
that it stands on the feed screw housing.
5. Remove the frame cover from the underside of
the snowblower by removing the screws which
hold the cover.
6. Slide the drive belt from the roller and between
the friction wheel and friction wheel disc.
7. Remove the belt and put the new one back on by
proceeding in reverse order.
Holding the drive clutch lever down makes it easier to
reinstall the belt.
If an assistant is available, you can also disconnect
the feed screw housing from the frame unit in order to
replace the belt.
1. Switch the engine off, remove the key, disconnect
the ignition cable and allow the unit to fully cool
down.
2. Remove the belt cover.
3. Remove the shaft gear cover and pull the shaft
blocking cable, the baffle cable and the ejection
shaft control rod.
4. Remove the cover downwards in order to avoid
bending when tipping the unit.
5. Remove the screws that attach the feed screw
housing to the frame (two on each side). Tip the
feed screw housing and frame so that they sep-
arate.
6. Replace the feed screw belt or the drive belt.
7. Tip the feed screw housing and frame so that they
fold together and secure them with the bolts.
Holding the feed screw clutch lever down makes it
easier to connect the feed screw housing and frame.
8. Place the belt(s) on the engine roller(s).
9. Refit the shaft blocking cable, the baffle cable and
the ejection shaft control rod.
10. Refit the shaft gear cover.
Friction wheel replacement (Fig. 24 - 27)
If the snowblower does not move forward when the
drive clutch is engaged and adjusting the clutch con-
trol cable does not remedy the problem, the friction
wheel may need to be replaced.
Attention! No smoking and no open flame. Risk of ex-
plosion!
Lubrication (Fig. 28 + 29)
Feed screw transmission
The transmission has been filled with lubricant at the
factory up to the appropriate level. No additional lu-
bricant is required unless there are signs of a leak or
repair work has been carried out on the transmission.
If lubricant is required, use GL-5 or GL-6, SAE-95,
EP transmission oil lubricant. Do not use synthetic oil.
General lubrication
Lightly lubricate all moving parts of the machine at
the end of the season or every 20 operating hours.
• Do not allow lubricant or oil to get onto the brake
lugs, brake discs or belts. Do not oil the machine
too much; excess oil can get into the drive and re -
sult in the drive belt slipping.
• When lubricating the feed screw shaft, remove the
clevis pin to apply oil to the inside of the shaft and
the spacers and flange bearings which are at both
ends of the shaft.
• Remove the wheels in order to lubricate the wheel
shaft.
Repair
Feed screw belt (Fig. 17 - 20)
If the feed screw belt is worn, full of oil or otherwise
occupied, proceed as follows in order to change the
belt.
1. In order to prevent spillage, remove the fuel from
the tank by closing the fuel valve and running the
engine until it stops. Then, open the tank cap and
let the petrol completely drain into a sufficiently
large container by tilting the machine or sucking it
out. Then, close tank cover again.
2. Remove the two screws that hold the belt cover
and place the cover to one side.
3. Unwind the feed screw belt(s) from the engine
roller.
4. Carefully turn the snowblower up and forward so
that it stands on the feed screw housing.
5. Remove the frame cover from the underside of
the snowblower by removing the screws which
hold the cover.
6. Remove the belt(s) from the feed screw roller and
slide the belt(s) between the mounting bracket
and the feed screw roller.
7. Replace the feed screw belt by carrying out the
instructions in reverse order.
Drive belt (Fig. 21 - 23)
If the drive belt is worn, full of oil or otherwise occu-
pied, proceed as follows in order to replace the belt.
