The operation of any powered outdoor equipment can result

in foreign objects being thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields before beginning snow thrower opera-

tion. We recommend Wide Vision Safety Mask for over spectacles or standard safety glasses, available at

SEARS Retail or Catalog Stores. Familiarize yourself with the equipment and with the

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

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

following precautions"

1, Move impeller/auger drive control lever to

OFF position.

2. Move wheel drive control lever to NEUTRAL

position.

3. Move throttle lever to STOP position.

4. Turn key to OFF position.

5. Remove spark plug.

6. Do not place your hands in the auger or

discharge chute. Use a pry bar. The engine compression could cause the auger to rotate sharply when lodged item is removed, if above precautions

are not followed.

7. To move unit backwards: Place wheel drive control

lever in REVERSE position and press the power clutch lever. To stop backward motion: Release pressure from power

clutch lever. Return wheel drive control lever to NEUTRAL position.

ENGINE SERVICE

Unless the operator is fully qualified to make engine adjustments and repairs, it is recommended that such work

be done by technicians trained to work on snow thrower type gasoline engines.

The Engine Repair Parts section of this manual contains a

list of engine rep{acement parts and illustrations to assist the

trained technicians in making repairs and ordering proper

replacement parts.

The snow thrower should be immediately prepared for

storage at the end of the season or if the unit is to be un-used for 30 days or more.

ENGINE STORAGE

DANGER

Never store engine with fuel in tank indoors or in enclosed, poorly ventilated enclosures, where fuel fumes may reach an open flame, spark or pilot light

as on a furnace, water heater, clothes dryer, etc.

Gasoline, if permitted to stand un-used for extended periods (30 days or more), may develop gummy deposits which can adversely affect the engine carburetor and cause engine malfunction, To avoid this condition, proceed as follows:

._r_//// /

UNIT STORAGE

1. Clean the unit thoroughly; remove all debris and wipe

the unit dry.

2. Inspect ti_e snow thrower for worn or damaged parts,

tighten all loose hardware.

3. Oil all points described in paragraph Lubrication.

4. Store the snow thrower in a protected area and cover

the unit for additional protection. A yearly checkup or tuneup by the SEARS Service

Department is a good way of insuring that your snow thrower will provide maximum performance for the next

season.

DANGER

Handle gasoline carefully, It is highly flammable and

careless use could result in serious fire damage to your person and/or property.
