6.2 OIL CHANGE
Change the oil the first time after 2 hours of operation, and
subsequently every 50 hours of operation or once a season.
Change oil when the engine is warm.
The engine oil may be very warm if it is drained off
directly after the engine is shut off. So allow the
engine to cool a few minutes before draining the
oil.
1. Lean the snow thrower slightly so that the oil draining
plug (14 in fig. 1) is the lowest point of the engine.
2. Unscrew the oil draining plug.
3. Let the oil run out into a container.
4. Screw back the oil draining plug.
5. Fill with new oil: See BEFORE STARTING above for
type and amount.
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: LD F5TC or equivalent.
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.
6.5 TYRE PRESSURE
The air pressure should be equal in both tires for best
performance. Be sure to keep caps on valves to prevent entry
of debris into the valve stem when tires are filled.
Recommended air pressure: 1.2 bar.
6.6 LUBRICATION
No service must be carried out before:
- The engine has stopped.
- The cable has been disconnected from the spark
plug.

6.6.1 Linkages
See fig. 15. Lubricate the linkages below every 10:th hour of
use and before long time storage. Use 10W oil.
• Lever bearings
• Drive belt tension arm
• Auger belt tension arm
6.6.2 Gearbox
No parts inside the gearbox are 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.
For long time storage the above-mentioned parts should be
lightly wiped with an oily rag to prevent rust.

7 SERVICE AND REPAIRS
