Note: The electrical starting motor has overload protection. The motor stops automatically when overheated. It will not restart until it has cooled, which takes about 5 - 10 minutes.

5.6 STOPPING

1. Release both clutch levers. Note. If the snow thrower

continues rotating - see ADJUSTING THE CONTROL WIRES below.

2. Push the throttle to idling position . Let the engine run

on idle a few minutes to melt the snow.

3a. Machines without an electric starter:

With the engine running, pull out the start handle a few times to prevent the starting apparatus from freezing. An unusual rattling noise occurs. This does not damage the engine.

3b. Machines with an electric starter:

With the engine running, keep the start button pressed in for a few seconds to prevent the starting motor freezing (see above for connecting electric cable). An unusual rattling noise occurs. This does not damage the engine.

4. Push the throttle to the bottom to position .

5. Remove the ignition key. Do not turn the key!

If the machine is left unattended, stop the engine and remove the ignition key.

5.7 STARTING

1. Start the engine as above. Let the engine run a few

minutes to warm before use.

2. Set the chute deflector.

3. Turn the adjustment lever and set the deflector to throw the snow in the direction of the wind.

For manual models; The gear stick must not be moved if the driving clutch lever is depressed.

4. Set the gear/speed lever to a suitable position.

5. Press down the auger clutch lever (16 in fig. 1) to activate the auger and discharge fan.

Watch out for rotating auger. Keep hands, feet, hair and loose clothing away from any moving parts on the machine.

The machine is equipped with one-hand-control. This means as follows:

1. Press down the left and the right lever.

2. Now, the right lever can be released to manoeuvre the snow throwing direction, snow throwing length and for the HST model, the speed.

3. When the left lever is released, the one-hand-control is deactivated and the right lever will also be released.

5.8 DRIVING TIPS

1. Always run the engine on full throttle or next best.

The silencer and surrounding parts become very hot when the engine is running. Risk of burns.

2. Always adapt the speed to the snowy conditions. Regulate the speed with the gear stick not the throttle.

3. Snow is more effectively removed directly after falling.

4. Always throw the snow in the direction of the wind if possible.

5. Adjust the shoes with the screws (13 in fig. 1) to suit the ground conditions:

- On flat ground, e.g. asphalt, the shoes should be about 3 mm under the scraping blade.

- On uneven ground, e.g. gravel paths, the shoes should be about 30 mm under the scraping blade.

Always adjust the shoes so that gravel and stones are not fed into the snow thrower. There is a risk for personal injury if these are thrown out at high speed.

Ensure the shoes are adjusted the same on both sides.

6. Adapt the speed so that the snow is thrown in an even stream.

If snow fastens in the chute do not try to remove it before:

- Releasing both clutch levers.

- Stopping the engine.

- Removing the ignition key.

- Disconnecting the cable from the spark plug.

- Do not put your hand inside the chute or auger. Use a wooden stick.

ENGLISH

5.9 AFTER USE

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

11.

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.

Machine Pressure

966 D 1.4 bar 1171 HST 1.0 bar 1381 HST 1.0 bar

6.5 CARBURETTOR

The carburettor is factory set. If adjustment is required, contact an authorised service station.

6.6 LUBRICATION

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.

ENGLISH

6.6.4 Chute worm gear

See fig. 13. If the discharge chute is difficult to operate, first lubricate the

pinion gear (B) and ring gear (A). If it is still difficult to operate, adjust as follows:

1. Loosen the nut (C), which holds the pinion gear bracket in the slotted hole.

2. If the pinion gear is too tight against the ring gear, move it away slightly and then retighten the nut.

3. Check the operation again.

Note! If the discharge chute will not stay in position, adjust the pinion gear (B) closer to the ring gear (A).

6.6.5 Hexagonal shaft, Man

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.

For long time storage the above-mentioned parts should be lightly wiped with an oily rag to prevent rust.

6.6.6 Hydrostat, HST

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
