Operation

FREE-WHEELING AND
TRACTION DRIVE LOCK

For easy turning when pushing the snowthrower, you
can disengage the traction drive at one or both wheels
by using the Traction Lock Pins (See Figures 14 & 15.)

1. Turn the unit off, remove the Engine Key, and discon-

nect the spark plug wire.

2. To DISENGAGE the traction drive lock, insert the

Traction Lock Pin through the outer hole in the axle.
(See Figure 14).

3. To ENGAGE the traction drive lock, insert the pin

through the hub and axle (See Figure 15). If the hole
in the hub is not aligned with the inner hole in the
axle, push the snowthrower until the holes align and
install the Traction Lock Pin.

NOTE: When snowthrowing with the full width of the
auger, for best drive performance engage both wheels.
For easier turning when not using the full width of the
auger, engage one wheel and use the engaged side as
the snow contact side for the auger.

AFTER EACH USE

Normal use of the snowthrower may result in a build-up
of packed snow in and around the starter cord housing
and around engine controls. Heat from the engine will
usually prevent the snow from freezing solid while the
unit is running, but after the engine is shut down, some
snow may continue melting from engine heat, and later
freeze around some moving parts as the unit cools.

After each period of use, follow these steps 

to prevent

freeze-up caused by ice formation in and around the
engine controls and external parts. 

1. Before shutting off the engine, pull the starter rope

out 2 - 3 times, and allow it to rewind slowly. This will
help clear packed snow from the starter cord area. 

2. Stop the engine by moving the Throttle Lever (See

Figure 11) down, or by pulling out the Engine Key.

3. Disconnect the spark plug wire, and position it away

from the spark plug.

4. Brush snow and ice from the snowthrower. Be sure to

clear engine and snowthrower controls, discharge
chute, worm and chute rod gears, clutch rod areas,
and anywhere else snow has accumulated.

5. Always remove the Engine Key and store in a safe

place to prevent unauthorized use.

6. If the snowthrower is kept in a cold shelter, fill the fuel

tank to prevent condensation. Do not store near
sparks or flame.

Note: The Engine Owner’s Manual contains further infor-
mation on preventing ice formation and freeze-up.

WARNING

Never store snowthrower, with gasoline in engine
or fuel tank, in a heated shelter or in enclosed,
poorly ventilated enclosures. Gasoline fumes may
reach an open flame, spark or pilot light (such as
a furnace, water heater, clothes dryer, etc.) and
cause an explosion.

Handle gasoline carefully. It is highly flammable
and careless use can result in serious fire
damage to people and property.

Drain fuel into an approved container outdoors
away from open flame or sparks.
