steering trigger to turn right. (Fig. 63)
To stop the product
1. Move the throttle control (A) to the STOP
position. (Fig. 64)
2. Remove the ON/OFF key.
To use the throttle control
Slide the throttle control (A) to change the
amount of fuel used. Always operate the engine
at full throttle. (Fig. 64)
To use the fuel switch
Slide the fuel switch (A) to open or close the fuel
valve. Operate the product with the fuel switch in
the OPEN position. (Fig. 65)
To use the choke control
Slide the choke (A) to open or close the choke
valve. Use the choke to start a cold engine. (Fig.
66)
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. 67)
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. 68)
2. Tighten the nuts.
3. Lower the drift cutters after use.
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
chute.
4. Turn the 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.
7. If the product has an electric starter, connect the
product to power and push the start button once
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.

Maintenance
Introduction
When the product is in use, bolts can loosen
and components can become worn. This can
cause malfunction like incorrect tolerance clearance,
increased oil consumption, or misalignment of
various components. Do regular maintenance on the
product to prevent malfunction.

Note: It is not necessary to add grease or to do
other maintenance to the gearbox.
To do a general inspection
Make sure that all nuts and screws on the
product are tightened correctly.
To do a check of the oil level
CAUTION: A too low oil level can
do damage to the engine. Do a check of
the oil level before you start the product.
1. Put the product on level ground.
2. Remove the oil tank cap with the attached
dipstick.
3. Clean the oil from the dipstick.
4. Put the dipstick fully into the oil tank to give a
correct picture of the oil level.
5. Remove the dipstick.
6. Examine the oil level on the dipstick.
7. If the oil level is low, fill with engine oil and do a
check of the oil level again.
To replace the engine oil
1. Run the engine a few minutes to make the oil
warm. Warm oil flows better and includes more
contaminants.
WARNING: The engine oil is
hot. Avoid skin contact with the used
engine oil.
2. Put the product on level ground.
3. Remove the ON/OFF key.
4. Put a container below the oil drain plug.
5. Remove the oil drain plug, tip the product and
drain the used oil in the container.
6. Put the product back to the operating position.
7. Install the oil drain plug and tighten it by hand.
8. Fill the engine with oil, see
To fill the engine with
oil on page 13
.
1Replace the oil after the first 20 h, 50 h, 100 h and then every 100 h.
2See Technical data for correct tire pressure.
3Check and clean spark plug before use each year.
16 2081 - 001 - 09.02.2023
To lubricate the product
Lubricate the pivot points (A) with oil.
Lubricate the engine (B) with oil.
Apply a small amount of lithium grease to the
interlock bosses (C) at the beginning of each
season or every 25 hours of use. (Fig. 69)
Muffler
The muffler keeps the noise levels to a minimum and
sends the exhaust fumes away from the operator.
Do not use the product if the muffler is missing or
defective. A defective muffler increases the noise
level and the risk of fire.
WARNING: The muffler becomes
very hot during and after use and when
the engine operates at idle speed. Be
careful near flammable materials and/or
fumes to prevent fire.
To examine the spark plug
CAUTION: Always use the
recommended spark plug type. Incorrect
spark plug type can cause damage to
the product.
Examine the spark plug if the engine is low on
power, is not easy to start or does not operate
correctly at idle speed.
To decrease the risk of unwanted material on the
spark plug electrodes, obey these instructions:
a) Make sure that the idle speed is correctly
adjusted.
b) Make sure that the fuel mixture is correct.
c) Make sure that the air filter is clean.
If the spark plug is dirty, clean it and make
sure that the electrode gap is correct, refer to
Technical data on page 23
. (Fig. 70)
Replace the spark plug if it is necessary.
To inspect the augers and the
scraper bar
1. Before each use, inspect the augers and the
scraper bar for wear.
2. If the edge of the scraper bar is worn, reverse the
scraper bar. If the scraper bar has damages or is
worn on both edges, replace it.
3. If the edges of the augers are worn, contact an
authorized service center to replace them.
To replace the auger shear pins
The auger shear pins protect the product from
damage. The auger shear pins break if an object
comes into the moving parts.
CAUTION: Use only original
equipment shear pins supplied with the
product.

spark plug cable.
3. Align the hole in the auger hub (B) with the hole
in the auger shaft (C) and install a new ¼ - 20 x 2
shear pin (A).
4. Install a ¼-20 locknut (D) on the shear pin and
tighten. (Fig. 71)
5. Put the ON/OFF key in the ignition and connect
the spark plug cable to the spark plug.
To replace the impeller shear pins
The impeller shear pins protect the product from
damage. The impeller shear pins break if an object
comes into the moving parts.
CAUTION: Use only original
equipment shear pins supplied with the
product.
1. If an impeller shear pin breaks, stop the engine
and wait for the moving parts to stop.
2. Remove the ON/OFF key and disconnect the
spark plug cable.
3. Align the hole in the impeller hub (A) with the
holes in the impeller shaft (B) and install a new
¼-20 shear pin (C).
4. Install a ¼-20 locknut (D) on the shear pin and
tighten. (Fig. 72)
5. Put the ON/OFF key in the ignition and connect
the spark plug cable to the spark plug.
To examine the tires
Keep the tires free of fuel, oil and chemicals to
prevent damage to the rubber.
Keep the tires away from stumps, stones, ruts,
sharp objects and other objects which can cause
damage to the tires.
Keep the tire pressure correct, see
Technical
data on page 23
.
