Before Starting
Installing the Discharge Chute
1. Position the chute deflector onto the discharge chute
and align the mounting holes (Fig. 5).
For safe and efficient use of your appliance, use only an
extension cord recommended for outdoor use. Use only a
2.5 mm2 extension cord up to 25 m long.

Warning
5
Contact with water while operating the
snowthrower can cause electric shock, resulting in
personal injury or death.
6
Don’t handle the plug or the appliance with wet
hands or while standing in water.

Warning
The electrical cord can get damaged, causing a
shock or fire.
Thoroughly inspect the electrical cord before
using the snowthrower. If the cord is damaged, do
not operate the snowthrower. Repair or replace
the damaged cord immediately. Contact an
Authorized Service Dealer for assistance.

Operation
• To adjust the discharge chute, rotate the chute crank
clockwise to move the discharge chute to the left;
counterclockwise to move it to the right.
Check the condition of the snowthrower before operating
it to ensure that the rotor turns freely.
Note: The chute crank makes a noise as you turn the
crank. This is normal.
To adjust the height of the snow stream, raise or lower
the chute deflector handle (Fig. 8).
Starting and Stopping
1. To start the rotor, squeeze the control bar (Fig. 7).

Operating Tips
Warning
Warning
A gap between the discharge chute and the chute
deflector may allow the snowthrower to throw
snow and objects in the direction of the operator.
Thrown objects could cause serious personal
injury.
If snowthrower hits an object while in operation,
the object could be thrown in operator’s or
bystander’s direction. Thrown objects could cause
serious personal injury.
• Do not force the chute deflector too far forward
so that a gap appears between the discharge
chute and chute deflector.
• Do not overtighten the locknuts that hold the
chute deflector in place.
Keep the area to be cleared free of all objects
which may be picked up and thrown by the rotor
blades.
• Always keep children and pets away from the area of
operation.
• Begin removing snow near the electrical outlet and
work outward. Blow back and forth, not away from
and toward the outlet.
• Keep the area to be cleared free of stones, toys, or
other objects which the rotor blades can throw. Such
items could be covered by snowfall and go unnoticed.
If the snowthrower strikes an object during operation,
stop the snowthrower, unplug the extension cord,
remove the obstruction, and check the snowthrower for
damage.
• When turning at the end of a swath, step over the cord
and turn the snowthrower.
• Always overlap each swath and discharge the snow
downwind when possible.
8
• When operating the snowthrower, keep the wheels
1 inch (2.5 cm) off the pavement by tipping the
snowthrower forward. This helps prevent the snow
from building up on the wheels.
• To shave down large banks of snow, lift the
snowthrower by the primary and secondary handles
(Fig. 9) and place the snowthrower on the bank. Let
the weight of the snowthrower shave down the bank in
a back-and-forth motion.
• After clearing the snow, let the motor run for a few
minutes so that moving parts don’t freeze. Then shut
off the motor, wait for all moving parts to stop, and
wipe the ice and snow off the snowthrower. Rotate the
chute crank several times to remove the snow.

Maintenance
2
Important All electrical repairs should be performed
only by an Authorized Service Dealer.
Note: Determine the left and right sides of the
snowthrower by standing in the normal operating position.
Warning
1516
If the extension cord is plugged into the
snowthrower, someone could accidentally operate
snowthrower while you are performing
maintenance on it, causing serious personal
injury.
Figure 9
1. Primary handle
2. Secondary handle
• When clearing steps, hold the snowthrower by the
primary and secondary handles and use a swinging or
sweeping motion.
Disconnect the extension cord before you perform
any maintenance.
Warning
Lubricating the Snowthrower
When using the secondary handle, never direct
the snow discharge chute at the operator or
bystanders. The snowthrower can throw objects
and cause serious personal injury.
You do not need to lubricate the snowthrower; all the
bearings were lubricated at the factory for the life of the
snowthrower.
When using the secondary handle, always turn the
discharge chute in the opposite direction from
where you or bystanders are standing.
• Keep the extension cord clear of obstructions, sharp
objects, and all moving parts. Do not pull sharply on
cord or abuse it in any manner. Frequently inspect the
extension cord for damage that may result in an
electric shock. If the extension cord becomes
damaged, replace it.
• In cold and snowy weather conditions, some controls
and moving parts may freeze. Therefore, when any
control becomes difficult to operate, stop the motor,
disconnect the extension cord, and check for frozen
parts. Do not use excessive force when trying to
operate frozen controls. Free all the controls and
moving parts before operating.

Replacing the Scraper
2. Use a 5/16-inch Allen wrench to turn the rotor shaft
clockwise (left-hand thread) while holding the rotor
(Fig. 12).
