6.3 SPARK PLUG
Check the spark plug once a year or every hundred hours of
use.
Clean or change the plug if the electrodes are burnt. The
engine manufacturer recommends: Champion RC12YC.
Correct spark gap: 0.7/-0.8 mm
6.4 CARBURETTOR
The carburettor is factory set. If adjustment is required,
contact an authorised service station.
7 LUBRICATION
No service must be carried out before:
The engine has stopped.
The ignition key has been removed.
- The starting cable has been disconnected from
the spark plug.
If the instructions say that the machine is to be lifted at the
front and rested on the auger housing then the petrol tank
must be emptied.
Empty the petrol tank outdoors when the engine is
cold. Do not smoke. Empty into a container
designed for petrol.
7.1 DISCHARGER
Lubricate the discharger flange and the adjustment lever
worm gear every 5th hour of use and before long time
storage.
7.2 THE AUGER SHAFT
Lubricate the auger shaft lubricating nipples with a grease
gun every 10th hour of use (fig 11). Always lubricate the
shaft when changing the shear bolts.
Dismantle the bolts for long time storage. Lubricate with the
grease gun and then rotate the auger freely on the shaft before
replacing the bolts.
7.3 WORM GEAR
The worm gear if filled with special lubricant at the factory.
Refilling is not normally required.
Loosen the plug once a year and check if the worm gear
contains lubricant (fig 12).
If it is leaking or has been repaired it must be refilled with
lubricant. The worm gear holds 92 grams of lubricant at the
most.
Use Shell Darina 1, Texaco Thermatex EP1, Mobiltem 78,
Benalene #372 Grease or similar.
7.4 HEXAGONAL SHAFT
The hexagonal shaft, chain sprocket and chains are not to be
lubricated. All bearings and bushings are permanently
lubricated and require no maintenance.
Lubricating these parts will only result in the grease getting
on to the friction wheel and disc drive plate, which could
damage the rubber clad friction wheel.
7.5 GENERAL ABOUT DRIVE BELTS
The drive belts should be checked and adjusted once per
season and replaced when needed. This should all be done at
an authorised service station.

8.1 ADJUSTING THE SCRAPER BLADE
The scraper blade gets worn after a lot of use.
Adjust the scraper blade (always together with the shoes)
The scraper blade is reversible so can be used on both sides.
8.2 ADJUSTING THE DRIVE BELTS
The drive belts should be checked (and adjusted if required)
for the first time after 2 – 4 hours use and then the middle of
each season. They should thereafter be checked twice a year.
When the belts are adjusted or changed, the control wires
must also be adjusted (see below).
8.2.1 The drive belt for driving (A in Fig. 17)
The belt has a spring-loaded tension pulley. Adjustment is
not required. If the belt slips, change it.
8.2.2 The auger drive belt (B in Fig. 17)
1. Remove the belt protective cover (1) by loosening the
screws (2). See fig. 14.
2. Loosen the tension-pulley (C) and move it about 3mm
towards the belt (fig. 17).
3. Tighten the tension pulley nuts.
4. Check the belt tension by pressing down the auger clutch
lever. With a finger, you should be able to push the belt
about 12 - 13 mm without any great power (fig 16).
5. Repeat the above procedure if further adjustment is
required.
6. Reassemble the belt protection. See fig 14.
8.3 ADJUSTING THE BELT GUIDE
1. Remove the spark plug protection.
2. Remove the belt protective cover (1) by loosening the
screws (2). See fig. 14.
3. Activate the auger clutch lever (A in fig 7).
4. Check the distance between the belt guide and the belt.
The distance should be 3 mm. See fig 13.
5. If adjustment is required, loosen the screw to the belt
guide and set the correct distance.
6. Tighten the screw properly.
7. Reassemble the belt protection.
