Operational Precautions,

OPERATING CONTROLS

Operating controls (figures 8 & 9) and their functions are as
follows:

• Power Clutch Lever - The power clutch lever controls

forward or reverse motion of the unit when the wheel

drive control lever is in the appropriate position. When
the operator's hand is removed from the power clutch

lever, tension is removed from drive belts, therefore
unit motion and impeller/auger rotation stop. Engage

slowly but firmly and all the way down against hand
grip.

• Impeller/Auger Drive Control Lever - Used to disen-
gage power to impeller/auger without interfering with

power to drive wheels. Pull up to engage. Push down to

disengage. NOTE: Power clutch lever must be in re-

leased (disengaged) position before impeller/auger
lever position is changed.

e Throttle Control Lever - This snowthrower is equipped

with a control panel mountedthrottle control lever used
to control speed of engine, There are three positions on

the throttle control - Stop - Slow - Fast.

O Wheel Drive Control Lever - Used to select desired unit

speed or direction. Choice of five forward speeds, neu-
tral and reverse.

_) Chute Deflector Lever- The distance snow will be dis-

charged can be adjusted by raising chute deflector
(figure 8) for more distance, or lowering for less dis-
tance. Pull lever up to top notch for most distance. Push

lever down to bottom notch for least distance.

When removing snow from rock or unpaved construction;
we suggest you raise the front of the machine with the skids.
To raise the machine with the skids:

1. Loosen the skid mounting nuts (figure 7) and push the

skid down until the front of the machine is raised to desired

height. Retighten mounting nuts.

2. Set skid on other side at same height. NOTE: Be sure

that front of unit is set at same height on both sides.

DANGER

Be certain to maintain proper ground clearance for
your particular area to be cleared. Objects such as
gravel, rocks or other debris, if struck by the

impeller/auger, may be thrown with sufficient force
to cause personal injury or property damage.

Do not put hands in or near the deflector chute while

the engine is running.

CHUTE CONTROL ROD

SNOW THROWER OPERATION

The most effective use of the snow thrower wilt be

establishsd by experience, taking into consideration the

terrain, wind conditions and the depth and weight of the

snow. It is the wind conditions and building location which
will determine the direction of the discharge chute. Since the
wind will tend to blow the discharged snow back into the
cleared area, it wilt be necessary to change the chute

direction to offset this condition. NOTE: Do not throw snow
towards a building as hidden objects could be thrown with

sufficient force to cause damage.
To engage the self-propeINng drive mechanism, proceed as

follows:

1. Start the engine as described in paragraph To Start

Engine.

2. Using the chute control rod (figure 9), position the

discharge chute so as to discharge the snow with the wind.

3. Select proper speed for snow conditions as outlined

below and set wheel drive control lever to desired position.

A. Number 1 position is for extra deep, wet, heavy

SROW,

B. Number 2 position is for deep, wet, heavy snow.

Experience will help make choice between position
1 and 2.

C. Number 3 position is for light fluffy snow.
D. Number 4 position is mainly for transporting unit

over bare or plowed areas, but may be used for very

light snow.

E. Number 5 position is for transporting unit over bare

or plowed areas.

4. Set the impeller/auger control lever to the ON position.

5. Press the power clutch lever to begin impeller/auger
