    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 (20 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.
    6.  Press down the auger clutch lever (16 in fig. 1). The snow 
    thrower now moves forward or backwards depending on 
    the gear you have chosen.
    7. One-hand-control.
    For manual models only; Never actuate the gear 
    lever when the one-hand-control or the drive lever 
    is actuated. This will serious damage the friction 
    wheel.
    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 the tool supplied.
    5.9 AFTER USE
    1.  Check for loose or damaged parts. If required, change 
    damaged parts.
    2.  Tighten loose screws and nuts.
    3.  Brush all the snow from the machine.
    4.  Move all the controls backwards and forwards a few 
    times.
    5.  Put the choke in position   
    6.  Disconnecting the starting cable from the spark plug.
    Do not cover the machine while the engine and 
    silencer are still warm.

    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 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. 
    6.3 SPARK PLUG
    Check the spark plug once a year or every hundred hours of 
    use.
    Clean or change the plug if the electrodes are 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. 
    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.
    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 (S in fig. 12)
    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. 
    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
    7 SERVICE AND REPAIRS
    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.

    7.9 DIFFERENTIAL (966 D)
    7.9.1 Description
    In the differential the drive force is transferred from the chain 
    drive to the right and left shafts via two free wheels, one for 
    each shaft.
    This means that the outer wheel can rotate faster than the in-
    ner wheel on bends.
    With the differential the snow thrower is as easy to drive 
    around bends as straight forward.
    The differential also makes the snow thrower easier to handle 
    on hard surfaces, for example in the garage or in the store.
    7.9.2 Replacing the differential
    See fig. 36.
    The differential (A) is replaced according to the following 
    instructions:
    1.  Remove the ignition key.
    2.  Lift the snow thrower forward and rest in on the auger 
    housing.
    3. Disassemble the wheels.
    4. Loosen the screws (3) and dismantle the bottom plate (2).

    9. Pull out the shafts from the differential and remove the 
    differential.
    10. Check the chains. Replace if required. The chains shall 
    not be lubricated. They are factory lubricated. Excessive 
    grease can spoil the friction if it reach the friction wheel 
    or the friction disc.
    11. Check the bearings for dissonance and uneven friction at 
    rotation. Replace if required.
    12. Reassemble all parts in the reverse order.7.10 HYDROSTAT (1171 HST, 1381 HST)
    7.10.1 Description
    See fig. 32.
    The hydrostatic power-transmission transfers the power from 
    the motor to the driving wheels with stepless ratio forwards 
    as well as backwards. 
    The unit consists of a hydraulic pump and a hydraulic motor. 
    The hydraulic pump can be set with an angle positioned disc 
    to pump different amount of oil.
    A big angle of the disc gives a big stroke to the peripheral 
    located pistons and such a big oil flow.
    A small angle gives a small stroke and such a small oil flow.
    By angeling the disc over to the other side, the oil will flow 
    in the opposite direction and the machine moves backwards.
    The oil flow is then conducted to a hydraulic motor. The 
    hydrauic motor has a fixed angle positioned disc to which the 
    peripheral located pistons push. This makes the unit, where 
    the pistons are located, to rotate.
    7.10.2 0Troubleshooting
    See fig. 33-35.
    At malfunction in the hydrostat, in first-hand check the 
    following:
    1. The by-pass valve shall be in closed position. I.e. the 
    lever (K) in fig. 35 shall be in its forward position in the 
    machines´ direction of travel.
    2. The speed lever (J) shall be able to move between its end 
    positions when actuating the handlebar speed lever. Ev. 
    adjustments is performed at the link (7) in fig. 7.
    3. Check that the driving belt is intact. See 7.6.
    4. Check the oil level. See below.
    7.10.3 Replacing the hydrostat
    See fig. 33-35.
    The hydrostat, (B) in fig. 33, can be replaced according to the 
    instructions below:
