Not STH 953 W: For transportation, the tyres may show a higher level of air pressure. Check air pressure in the tyres; adjust it if required (approx. 1 bar).

Adjust the machine to suit the snow and ground conditions

Setting the working position

(machines with track drive) Figure 4

Choose a suitable position using the adjustment lever (1). - Position I: For heavy and icy snow. Auger is pressed to the ground. - Position II: For normal snow conditions. - Position III: To clear uneven paths or to transport the machine. The auger has a greater distance to the ground.

Adjusting the clearing plate (only STH 953 W)

Figure 10

If the machine is sitting on even ground, the auger (1), clearing plate (2), and wheels (3) must touch the ground simultaneously.

A clearing plate that is adjusted too high will cause the snow to be thrown to the rear. A clearing plate that is positioned too low will wear faster. Tilt the appliance rearward. Loosen nuts (5). Adjust the clearing plate higher or lower (as required) and reattach. Tilt the machine backwards, check adjustment, and repeat if necessary.

Adjusting the skids

Not STH 953 W

Figure 7

The landing skids (1) can be used to adjust the distance between the ground and the clearing plate (5) in such a way that no parts of the ground (such as soil or stones) are picked up.

Machines with track drive: Set the gear lever to position II. Loosen the nuts (2) on both sides of the appliance. Adjust the landing skids according to the underground surface: set them lower for uneven or loose paths; higher for even roads and paths. Fasten the landing skids with nuts (2) in such a way that they uniformly touch the ground from the bottom.

Operation

Safety instructions

Danger

Risk of injury!

• Keep persons, especially children, and pets away from the hazardous zones.
• Operate the machine only in a safe and perfect working condition.
• Check the area where the machine is to be used and remove all objects that can get picked up and thrown out by the machine.
• Work only with adequate lighting.
• Only use the machine in walking speed.
• Work slowly and safely especially on uneven or loose paths and while reversing.
• Adjust the distance between the snail casing and the underground floor in such a way that the appliance does not pick up any foreign bodies (such as stones).

Danger

Risk of suffocation on account of carbon monoxide! Only operate the combustion engine while out in the open.

Note

Follow the national/ local regulations for the usage times (ask the local authorities, if required).

Danger

Long hours of using the appliance can cause circulation problems in the hands on account of vibrations.

It is not possible to specify a generally valid operation time, since this depends on several factors:

• Proneness to blood circulation deficiencies (cold, numb fingers). Low ambient temperature. Wear warm gloves to protect hands. -A firm grip impedes blood circulation.
• Continuous operation is worse than an operation interrupted by pauses.

In case of regular, long-term operation of the device and in case of repeated occurrence of the symptoms (e.g. cold, numb fingers) please consult a physician.

Tips for clearing the snow

• Clear up immediately after the snowfall; otherwise, the lower layer becomes ice and makes clearing difficult.
• If possible, clear the snow in the direction of the wind.
• Clear the snow in such a way that the clearing tracks overlap a little.

Working on slopes

△Danger

Risk of injury! Danger of tipping if gradient is too high. - Do not use the appliance on slopes with an inclination greater than 20% . Work slowly and cautiously, especially while changing the direction of travel. - Drive up and down the slope - never diagonally to the slope. - Pay attention to hurdles - do not work close to the inclination.

Setting the direction and distance of throw

Figure 9

Danger

Risk of injury! Do not direct the flap (2) of the discharge shaft (3) towards persons, animals, windows, cars and doors.
