5.6 Starting
Never aim the snow at bystanders.
Always stop the engine before unclogging.
Always wear eye protection when operating the
snow thrower.
1. Start the engine as above.
2. Set the height of the deflector (5, 9:L). Upwards gives a
longer throwing distance and downwards gives a shorter
throwing distance.
3. Set the discharge chute with the lever (5, 9:E) so that the
snow is thrown downwind.
4. Start the auger and propulsion by activating the auger
drive lever (5, 9:M).
5. Stop working by releasing the
auger drive lever (5, 9:M).
6. Any unclogging can easily be carried out with a piece of
wood or similar after the engine has stopped.
The propulsion of the snow thrower starts when the auger
touchs the ground. To facilitate propulsion, raise the
handlebar a little. Do not push the snow thrower.
Attention! If the auger continues to rotate even though the
auger drive lever (5, 9:M) has been released, adjust the wire.
See ‘Maintenance’.
Attention! If the auger does not start even though the auger
drive lever (5, 9:M) has been activated, adjust the wire. See
‘Maintenance’.
5.7 Operating tips
1. Clear away the snow immediately after snowfall.
2. For complete snow clearance, slightly overlap each
clearance pass.
3. If possible, discharge the snow downwind.
4.6. In strong wind, lower the deflector to direct the
discharged snow close to the ground, where it is less
likely to blow into unwanted areas.
5. For safety and to prevent damage to the snow thrower,
keep the area to be cleared free of stones, toys and other
foreign objects.
6. The snow thrower’s capacity depends on the depth and
density of the snow. Learn how the snow thrower works
in different snow conditions.
5.7.1 Dry and normal snow
Snow up to 20 cm deep can be removed quickly and easily
by clearing at an even speed. For snow or drifts of a greater
depth, lower your speed and let the machine work at its own
pace.
Plan for downwind discharge of the snow.
5.7.2 Wet, packed snow
Drive slowly forward. Avoid to use the scraping blade to
remove remaining packen snow and ice. Hoeing will lead to
fatigue failure in the auger housing.
5.8 After use
1. Allow the engine to run for a few minutes after each snow
clearing operation to allow ice and snow on the snow
thrower to melt away.
2. Check that there are no damaged or loose parts. Repair/
replace parts if necessary.
3. Tighten loose screw joints.
4. Shut off the choke.
5. Remove the spark plug cable from the spark plug.
6. Clean the snow thrower after each use. Wash off with
water to remove salt or other chemicals. Wipe the snow
thrower dry
6 MAINTENANCE
Before carrying out maintenance work,
disconnect the cable from the spark plug.
6.1Oil change
Change the oil the first time after 2 hours of operation, and
subsequently every 25 hours of operation or at least once a
season. Change oil when the engine is warm.
The engine oil is very hot immediately after the
engine is shut off. Allow the engine to cool before
draining the oil. Risk of burns.
1. Remove the oil filler cap (5, 9:U) and dipstick. The
oil is drained by dismantling the plug (7, 10:V).
2. Place a container on the floor for the oil to run into.
3. Install the plug (7, 10:V).
4. Stand the snow thrower up and fill with new oil. See
“Before starting”.
Check that the plug is correctly tightened. If it
comes loose during operation, the engine will be
destroyed.
6.2 Spark plug
Before disconnecting the spark plug, clean around its
mounting.
Replace the spark plug once a year or every hundred hours of
use.
Spark plug: Champion RV 19 LM or equivalent.
Tightening torque: 24-27 Nm.
Electrode distance: 0.7-0.8 mm
6.3 Carburettor
The carburettor is factory set. If adjustment is required,
contact an authorised service station.
7 LUBRICATION
Before carrying out maintenance work, disconnect
the cable from the spark plug.
SNOW SN 522:
Lubricate the adjustment lever’s gear and the discharge chute
before storing the snow thrower for the summer. Use a
clinging type of grease, e.g. Lubriplate.
8 SERVICE AND REPAIRS
8.1 Adjusting cable (SN 522)
The auger drive lever’s cable is adjusted at the factory. Any
adjustment is carried out as follows:
1. Unhook the cable at the auger drive lever (5:M).
2. Remove the casing and disconnect the cable from the
appropriate hole in the plate. See figure 12.
3. Reinstall the cable in the new hole as required. Replace
the casing, hook the cable onto the auger drive lever.
