6.2OIL 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 to the right 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.

6.3SPARK PLUG
Check the spark plug once a year or every hundred hours of use.
Clean or change the plug if the electrodes are burned. The engine manufacturer recommends: RC124YC or equivalent.
Correct spark gap:
The spark plug is accessible under the protection plate in fig. 11.
6.4TYRE 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. The recommended air pressures are shown in the table below.
Machine | Pressure |
|
|
966 D | 1.4 bar |
|
|
1171 HST | 1.0 bar |

6.5CARBURETTOR
The carburettor is factory set. If adjustment is required, contact an authorised service station.
6.6LUBRICATION
No service must be carried out before:
-The engine has stopped.
-The ignition key has been removed.
-The 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.
6.6.1 Discharger
Lubricate the discharger flange and the adjustment lever worm gear every 10:th hour of use and before long time storage.
6.6.2 The auger shaft
Lubricate the auger shaft lubricating nipples with a grease gun every 10th hour of use (fig. 12). 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.
6.6.3 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 Benalene #900 Grease or similar.
