To adjust the discharge chute and
the discharge chute deflector

snow throwing distance.
b) Move the remote control lever down to increase
the snow throwing distance.
To adjust the skid plates
The skid plates prevent damage to the bottom of the
snow thrower. Adjust the skid plates (A) when the
locknut (B) is loose, or the skid plate is not at the correct
distance from the ground. No adjustment is necessary
for standard installation.
1. Loosen the locknut (B) with a 13 mm (½ in.) open
wrench.
2. Move the skid plates (A) up or down.
a) On flat surfaces set the distance between the
scraper bar and the ground to 5-6 mm (0.2-0.25
in).
b) On rough surfaces set the skid plates (A) in a
position where the scraper bar is above the top
of the ground.
WARNING: Make sure that gravel
and stones do not go into the
product. Objects that eject at high
speed can cause injury.
3. Tighten the locknut (B).(Fig. 61 )
To use the drift cutters (if equipped)
Use the drift cutters to cut through snowdrifts deeper
than the front of the product.
1. Loosen the adjustment nuts (A) on both sides of the
product to allow each drift cutter (B) to be raised to
its highest position.(Fig. 62 )
2. Tighten the nuts.
3. Lower the drift cutters after use.
To adjust the height of the auger
bucket (for ST 424T/427T/430T only)
1. Push the lever (A) down. (Fig. 63 )
2. Move the handles (B) up or down to adjust the height
of the auger bucket .
3. Release the lever (A) to lock the auger bucket in
position.
Note: The auger bucket can be set to an unlocked
position. This lets the auger bucket adapt to the terrain.
To set the auger bucket to the unlocked position, push
the lever (A) down and to the right.
To prevent freeze-up after use
Note: Controls and moving parts can be blocked by ice.
Do not apply much force to the controls. If you cannot
operate a control or a part, start the engine and let it
operate for some minutes.
1. Start the engine and let it operate for some minutes.
Stop the engine and wait for all moving parts to stop.
2. Remove snow and loose ice from the product.
3. Remove snow and loose ice from the base of the
discharge chute.
4. Turn the discharge chute deflector to the left
direction and to the right direction to remove ice and
water.
5. Set the key to the "OFF" position.
6. If the product does not have an electric starter, pull
the starter rope handle several times to remove ice
and water.
To get a good result
• Always run the engine at full throttle or near full
throttle.
• Always adapt the speed of the product to the snow
situation and adjust the speed with the drive speed
control lever. Make sure that the product throws
snow evenly.
• It is easier and more efficient to remove snow
immediately after it falls.
• Always throw snow downwind whenever possible.
• On flat surfaces, like asphalt roads, raise the skid
plates up to 5-6 mm (0.2-0.25 in) off the ground.
• The scraper bar is reversible. When it becomes worn
almost to the edge of the housing, reverse it.
Replace the scraper bar if it is damaged, or if both
sides are worn.
• Do not dispatch the chute deflector if it is clogged.
• If the product does not move forward due to
unforeseen circumstances, release the drive
engagement immediately or move the ON/OFF key
to the "OFF" position.
