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.

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
rotation and forward motion. As the unit starts to move, maintain a firm hold on the bandies and guide the snow
thrower along the cutting path. Do not attempt to push the unit. "-,
6. To disengage the drive mechanism: Release the power
clutch lever. Set the wheel drive control lever to the NEUTRAL position. Set the impeller/auger drive control
lever to the OFF position.
A DANGER
