Safety information

General safety information

Get to know your machine

Only trained adults may operate the machine, never children.
Read and understand the operating manual and safety instructions for the machine. Learn its use and limitations as well as its inherent potential dangers.
You must familiarise yourself with the controls and proper operation. You must know how to stop the machine and shut down the controls quickly.
Do not attempt to operate the machine until you fully understand how to properly operate and maintain the engine and how to avoid accidental injury and/ or property damage.

Working range

Never start or allow the engine to run in an enclosed area. The exhaust gases are dangerous because they contain carbon monoxide, an odourless and deadly gas. Only operate this unit in a well-ventilated outdoor area.
Never operate the machine when visibility is poor.
Never operate the machine on steep terrain.

Personal safety

Do not operate the machine while under the influence of drugs, alcohol or medication as they will impair your ability to use the machine prperly.
Dress appropriately. Wear long trousers, boots and gloves. Do not wear loose clothing, shorts or jewellery of any kind. Fix long hair in place so that it is above shoulder height. Keep hair, clothing and gloves away from moving parts. Loose-fitting clothing, jewellery or long hair may become caught in the moving parts.
Use safety equipment. Always wear safety goggles, hearing protection, safety gloves and safety shoes which may be used for the appropriate conditions.
Check your machine before starting. Safety devices must be in their intended location and be in perfect condition. Make sure that all nuts, pins, etc. are tight. Disengage all clutches and put the engine in neutral before starting it.
Never operate the machine it if needs to be repaired or is not in perfect condition. Replace damaged, missing or defective parts before use. Check
the fuel system for leaks. The machine must always be in a safe operating condition.
Never make any unauthorised changes to the safety devices. Check that they are operating properly on a regular basis.
Do not use the machine if the throttle does not turn the engine on or off. Any petrol-driven machine that cannot be operated with the throttle is dangerous and must be replaced.
Get accustomed to checking whether the tool and adjustment key have been removed from the machine before starting it. An adjustment key or tool which is left on a rotating part of the machine can result in bodily injuries.
Remain vigilant and use the machine with common sense.
Do not operate the machine barefooted, with sandals or similar light footwear. Wear safety shoes that protect your feet and improve your grip on slippery surfaces. Always maintain your footing and balance. This gives you better control over the machine in unexpected situations.
Avoid unintentionally starts. Ensure that the engine ignition is in the OFF position before transporting the machine or carrying out any maintenance or repair work on the unit. Transporting or performing maintenance or repair work on a machine with the ignition on can cause accidents.

Fuel safety

Fuel is extremely flammable and its vapours can explode if they are ignited. Be careful during use in order to reduce the risk of serious bodily injuries.
When filling up or draining the fuel tank, use a proper fuel tank in a clean, well ventilated area outdoors. Do not smoke or allow sparks, naked flames or other ignition sources near when adding fuel or operating the unit. Never refill the fuel tank in enclosed spaces.
Keep earthed conductive objects, such as tools, away from live electrical parts and connections to avoid spark formation or arcing. These events could ignite fuel vapours.
Always switch off the engine and let it cool down before refilling the fuel tank. Never remove the fuel tank cover or add fuel while the engine is running or hot. Never operate the machine if there is a leak in the fuel system.
Where practical, remove the machine from the truck or trailer and refuel on the ground. If this is not possible, refuel the machine on the trainer with a portable container and not with a fuel nozzle.
Slowly loosen the fuel tank cover to release any pressure in the tank.
The fuel nozzle must remain in secure contact with the fuel tank or container opening the entire time until the end of the refuelling process. Do not use any device that locks the fuel nozzle open.
Never put too much fuel in the fuel tank. Do not fill the tank more than 12.5 mm (1/2”) below the bottom end of the filling nozzle to allow for space to expand because the heat of the engine and/or sun causes the fuel to expand.
Put all fuel tank and container covers back on again tight and wipe off any spilled fuel. Never operate the unit if the fuel tank cover is not tight.
You must not start the engine if fuel has been spilled. Move the machine away from the area of the fuel spillage and prevent creating any ignition sources until the petrol gases have dissipated. If fuel has been spilled on you or your clothing, this can result in serious bodily injuries if ignited. Therefore, wash and change your clothing immediately.
Store fuel in containers which are specifically designed and approved for this purpose.
Never refill the container in a vehicle or on a truck or trailer with combustible cladding. Before refilling, always position the container on the floor and far enough away from your vehicle.
Store fuel in a cool, well-ventilated place, at a safe distance from sparks, naked flames or other sources of ignition.
Never store fuel or machines with fuel in the tank in a building where vapours could reach sparks, naked flames or other ignition sources such as water heaters, ovens, clothes dryers or similar. Allow the engine to cool before storing the machine in enclosed spaces.

Use and care of the machine

Never pick up or carry the machine while the engine is running.
Do not exert any force on the machine. Use the machine for its intended purpose only.
Do not change the settings on the speed control and do not allow the engine to overrev. The speed control controls the maximum safe operating speed of the engine.
Avoid contact with hot fuel, oil, exhaust gases and hot surfaces. Do not touch the engine or exhaust silencer. These parts become extremely hot during use. They also remain hot for a long time after the unit has been switched off. Allow the engine to cool before carrying out maintenance or making adjustments.
If the machine hits a foreign object, stop the engine, disconnect the ignition cable, check the machine thoroughly for damage and repair any damage before restarting and operating the machine again.
If the machine starts to make unusual noises or vibrations, switch the engine off immediately, disconnect the ignition cable and determine the cause. Unusual noises or vibrations are normally a sign of a defect.
Only use spare parts and accessories approved by the manufacturer. Non-observance can result in bodily injuries.
Service the machine. Check for misalignment or jamming of moving parts, breakage of parts and other faults that could impair the operation of the machine. If the machine is damaged, have it repaired before use. Many accidents are caused by poorly maintained equipment.
The engine and silencer must remain free of grass, leaves and excess greases or carbon accumulations to reduce the risk of a fire.
Never pour or splash water or any other liquids onto the unit. Keep handles dry, clean and free of residues. Clean the machine after every use.
Follow the relevant waste disposal laws and regulations for petrol, oil etc. to protect the environment.
Keep the unused machine out of the reach of children and do not allow persons who are not familiar with the machine or the instructions to operate the machine. The machine is dangerous in the hands of untrained operators.
Have your machine repaired by qualified repair personnel using only identical spare parts. This ensures that the safety of the machine is upheld.

Specific safety rules

Do not operate the machine without wearing appropriate winter clothing.
Do not use the machine on a roof.
Do not allow the engine to run indoors except when starting the engine and transporting the snowblower in and out of a building. Open doors to the outside; exhaust gases are dangerous.
Always check the distance to the top and sides carefully before operation. Always watch out for traffic when operating the machine on streets or curbs.
Check the area to be worked thoroughly. Keep the working area clean and free of toys, foot mats, newspapers, sledges, boards, wires and other foreign objects that you could trip over or may be ejected from the feed screw. Look for weak spots on docks, ramps, or floors.
Plan your snowblower route to avoid discharging towards persons or into areas where property damage may occur.
Do not use the machine in the vicinity of slopes, ditches or mounds. The machine may suddenly fall if a wheel goes over the edge of a cliff or ditch or the edge collapses.
Bystanders, children and pets must keep a distance of at least 23 m (75 feet). If anyone approaches you, stop the unit immediately.
Use an earthed extension cable and connection socket for all machines with electrical drive engines.
Check the clutch and brake function frequently. Adjust them and repair if necessary. All movements of wheel drives and feed screws must be quickly stopped when the control lever is actuated.
The engine and the machine must be able to adjust to the outside temperature before snow is cleared.
Watch out for hidden dangers and traffic.
Do not overload the capacity of the machine by trying to clear the snow too quickly.
Do not throw the snow higher than necessary.
Adjust the height of the feed screw housing to prevent gravel or grit being sucked into the feed screw.Use extreme caution when operating.
Be careful in order to prevent slipping or falling, in particular when operating in reverse gear. Never operate the machine at high transport speeds on slippery surfaces. Always look down and behind you before and while moving backwards.
Do not operate the machine on steep slopes. Do not clear snow across slopes. All movements on slopes must be slow and gradual. Do not suddenly change speed or direction. Proceed slowly in order to prevent stopping or changing direction on slopes. Avoid starting or stopping on slopes. Do not park the machine on a slope unless absolutely necessary. When parking on a slope, the wheels must always be blocked.
Disconnect the power transmission to the feed screw when transporting or idle.
Release all control levers and stop the engine before leaving the operating position (behind the steering rod). Wait until the feed screw has come to a complete standstill before emptying the ejection shaft and making any changes or checks.
Hands making contact with the rotating parts in the ejection shaft is the most common cause of injury associated with the snow blower. Do not empty the ejection shaft if the engine is running. Switch the engine off before emptying the shaft and remain behind the steering rod until all moving parts have stopped. Never put your hands in the ejection or collection openings. Always use the cleaning tool to empty the ejection opening.

Residual risks
The machine has been built according to the state-of the-art and the recognised technical safety requirements. However, individual residual risks can arise during operation.

Health hazard due to electrical power, with the use of improper electrical connection cables.
Before performing setting or maintenance work, release the start button and pull out the power plug.
Furthermore, despite all precautions having been met, some non-obvious residual risks may still remain.
Residual risks can be minimised if the “Safety information” and the “Proper use” together with the operating manual as a whole are observed.
Avoid accidental starting of the machine: the operating button may not be pressed when inserting the plug in an outlet. Use the tool attachment that is recommended in this operating manual. This is how to ensure that your machine provides optimum performance.
Keep your hands away from the work area, when the machine is in operation.

Start up

ATTENTION!
Always make sure the device is fully assembled before commissioning!
**** Before starting the engine, check the oil level and ensure that the engine is in perfect condition.

Cold start – Electric starter 230V

The engine is equipped with a 230V electric starter as well as a recoil starter. The electric starter has a three-wire power cable and a connector and has been designed so that it works at the voltage specified on the plate.

Insert the safety ignition key into the ignition slot until you hear a click. Do not turn the key.
Ensure that fuel valve is in the OPEN position.
Move the choke control to the FULL position.
Squeeze the aspirator two or thee times. If the temperature is below -25°C, additional ventilation may be necessary. If the temperature is above 10°C, no ventilation is necessary.
Some snow engines are not equipped with ventilators because ventilation is not necessary for such engines.
Connect the extension cable to the engine.
Plug the other end of the extension cable into the earthed socket.
Push the start button until the engine starts.
**** In order to prevent damage to the electric starter, do not let it run continuously for more than
5 seconds with each start attempt. Wait 10 seconds between attempts.
If the engine starts, release the start button and move the choke control slowly to the OFF position.
Disconnect the extension cable from the connection socket first, then from the engine.

Cold start – Recoil starter

Ensure that fuel valve is in the OPEN position.
Insert the safety ignition key into the ignition slot until you hear a click. Do not turn the key.
Move the choke control to the FULL position.
Squeeze the aspirator two or thee times. If the temperature is below -25°C, additional ventilation may be necessary. If the temperature is above 10°C, no ventilation is necessary.
Excessive ventilation can result in too much fuel getting into the cylinder which prevents the engine from starting. If this does occur, wait a few minutes before attempting another start and do not press the ventilator.
Hold the recoil starter handle firmly and pull the rope slowly until you feel resistance. Allow the rope to recoil slowly.
Pull the rope quickly and forcefully with a consistent movement. The starter rope must not recoil quickly.
Repeat steps 5 and 6 until the engine starts.
If the engine starts, release the recoil starter handle and move the choke control slowly to the OFF position.

Warm start

Follow the steps above, wherein the choke control remains in the OFF position and do not use the aspirator.
The engine needs a few minutes to warm up otherwise it cannot reach its full power until it reaches normal operating temperature.
In the event of snow and cold, control and moving parts may freeze. Do not use too much force when trying to operate frozen controls. If you experience difficulties operating a control or part, start the engine and let it run for a few minutes.

Snowblowing tips

It is easier and more efficient to clear snow immediately after is has fallen. The best time to clear snow is early in the morning. At this time, the snow is normally dry and has not been exposed to direct sunlight and warm temperatures. The cleared paths should overlap somewhat to ensure all the snow is cleared.
With large areas, start in the middle and clear the snow to each side so that the snow is not cleared repeatedly. In the event of heavy snow, reduce the width of the snow clearing by ensuring that the paths overlap and that you move slowly. The snow should be cleared in the direction of the wind where possible. The engine must remain clean and free of snow during use. This encourages ventilation and increases the durability of the engine. Let the engine run for a few minutes after clearing the snow so that the moisture on the engine dries and moving parts do not freeze. Switch on the feed screw/ drive wheel so that the remaining snow is removed from inside the housing. Turn the ejection shaft so that it does not freeze. Stop the engine, wait until all moving parts have come to a standstill and remove any ice and snow from the snowblower. With the engine switched off, pull the recoil starter handle several times so that the recoil starter does not freeze.

Cleaning

Attention!

Always shut the engine down and remove the spark plug connector before carrying out any cleaning work.
We recommend that you clean the device directly after every use.
Wipe swarf and dust off the machine from time to time with a cloth.
Clean the device at regular intervals using a damp cloth and a little soft soap. Do not use any cleaning products or solvents; they could attack the plastic parts of the device. Make sure that no water can penetrate the device interior.

Transport

Between work areas

Set the throttle to slow or into the partial load position.
Push on the steering rod sufficiently so that the front part of the unit is raised from the ground a little.
Activate the drive clutch without activating the feed screw clutch.

Freewheel (Fig. 15 + 16)
Use the axle pin in order to use the drive or freewheel.
Unlock a wheel so that the unit can be turned easier or unlock both wheels for freewheeling.
In order to unlock a wheel, slide it inwards and insert the axle pin through the outer axle hole but not through the wheel hub.
In order to block a wheel, slide it outwards and insert the axle pin through the hole in the wheel hub and the outer axle hole.
**** Always switch the engine off, remove the key and close the fuel valve when transporting the unit on a truck or trailer. Do not transport the machine while the engine is running.
Take special care when loading or unloading the unit onto or from a trailer or truck.
Fasten the unit chassis onto the transport vehicle. Never fasten the unit to rods or bars which could be damaged.
Freewheel

Storage

At the end of the season or when the snowblower will no longer be used for the next 30 days, comply with the storage instructions.

Allow the engine to run with the fuel valve closed until the fuel lines and the carburettor are empty and it stops due to a lack of fuel.
Remove the safety ignition key and let the engine cool down.
Lubricate the machine as instructed. (see lubrication).
Clean the engine and the outside of the snowblower thoroughly.
Repair all rusted or chipped paint surfaces; grind the effected areas before applying paint and a corrosion protection agent in order to protect the metallic parts from rust.

Motor
Engine oil change
After 20 operating hours, the 1st oil change must be carried out. It must take place after 100 operating hours thereafter. The engine oil should be heated slightly (approx. 50°C) before carrying out oil changes. This makes it more viscous so that it flows more easily. If necessary, run the engine for a brief period.

Remove the right wheel drive on the oil outlet side by pulling out the axle pin and draining it into a suitable pan (min. 1 l) positioned below.
Open the oil drain screw and filing nozzle (dipstick) and allow the oil to drain completely.
Close the oil drain screw again and tighten it hand-tight.
Top up oil with a funnel, check the oil level with the dipstick and seal it again.
Recommended engine oil SAE 10W-30 or 10W-40 (depending on the operating temperature). Dispose of the used oil properly at a local used oil collection point. Dumping used oil in the soil or mixing it with waste is prohibited.
Please follow points 1-3 above to drain the engine oil and close the filling port (dipstick). When draining the petrol, close the fuel valve first, then open the tank cap and let the petrol completely drain into a sufficiently large container by tilting it or suctioning it out. Then, close tank cap again. Attention! No smoking and no open flame. Risk of explosion!

Lubrication (Fig. 28 + 29)
Feed screw transmission
The transmission has been filled with lubricant at the factory up to the appropriate level. No additional lubricant is required unless there are signs of a leak or repair work has been carried out on the transmission. If lubricant is required, use GL-5 or GL-6, SAE-95, EP transmission oil lubricant. Do not use synthetic oil.
Lubrication

General lubrication
Lightly lubricate all moving parts of the machine at the end of the season or every 20 operating hours.

Do not allow lubricant or oil to get onto the brake lugs, brake discs or belts. Do not oil the machine too much; excess oil can get into the drive and result in the drive belt slipping.
When lubricating the feed screw shaft, remove the clevis pin to apply oil to the inside of the shaft and the spacers and flange bearings which are at both ends of the shaft.
Remove the wheels in order to lubricate the wheels.
