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 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.

SPARK 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: 0.7-0.8 mm.
The spark plug is accessible under the protection plate in fig.

6.4 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. The
recommended air pressures are shown in the table below.

Original instructions for use
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. 10). 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 (S in fig. 10)
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. 10).
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.
6.6.4 Mechanism for chute rotation
See fig. 21.
Remove the cover.
If the chute is difficult to operate, first lubricate the gear (A).
If it is still difficult to operate, adjust accordingly to one or
both of the following:
• Loosen the chute retainer screws a 1/4-turn.
• Loosen the nuts (B) and adjust the mesh between the
motor gear and the chute gear. Tighten the nuts when
adjustment is finished.
6.6.5 Hydrostat
The hydrostatic transmission is factory-filled with oil at the
delivery. If it not has been opened (permitted to authorised
personell only) and if no leakage exist, there is no need for
filling-up. Normally, there is no need for oil change in the
transmissio.
