SAFE OPERATION PRACTICES

This symbol points out important safety instructions which, if not followed, could endanger the

personal safety and/or property of yourself and others. Read and follow all instructions in this manual before attempting to operate your snow thrower. Failure to comply with these instructions may result in personal injury. When you see this symbol—heed its warning.

Your snow thrower was built to be operated according to the rules for safe operation in this manual. As

DANGER:

This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it should be maintained in effective working order by the operator.

In the State of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester for the muffler is available through your nearest Sears Authorized Service Center (See the REPAIR PARTS section of this manual.)

with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. If you violate any of these rules, you may cause serious injury to yourself or others.

TRAINING

• Read this owner’s guide carefully in its entirety before attempting to assemble or operate this machine. Be completely familiar with the controls and the proper use of this machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.

Final Adjustments

Adjusting Auger Control

• To check the adjustment of the auger control, push forward the left hand clutch grip until the rubber bumper is compressed. There should be slack in the clutch cable.

• Release the clutch grip. The cable should be straight. Make certain you can depress the auger control grip against the left handle completely.

• If adjustment is necessary, loosen the hex jam nut and thread the cable in (for less slack) or out (for more slack).

• Recheck the adjustment. Tighten the jam nut against the cable when correct adjustment is reached.

Adjusting Traction Drive Control

• To check the adjustment of the traction drive control and shift lever, move the weight transfer lever to the transport position (shown in Figure 18 on page 13) and the shift lever all the way forward to sixth (6) position.

• With the traction drive control released, pull the triggers up to the handle and then push the snow thrower forward to check that the tracks turn.

• Squeeze traction drive control against the handle and pull the starter. The tracks should turn.

• Now release the traction drive control and pull the starter again. The unit should not move.

• Before proceeding with adjustment, make sure that the spark plug is disconnected.

• If the traction drive control needs adjustment, loosen the jam nut on the traction drive cable and thread the cable one turn. Recheck adjustment and repeat as necessary.

• Tighten the jam nut to secure the cable when correct adjustment is reached.

NOTE: Cables are out of adjustment if augers continue to turn when auger clutch is released and/or machine continues to run when drive clutch is released. For more details, refer to the Service and Adjustment section.

Adjusting Skid Shoe

The space between the shave plate and the ground can be changed by adjusting the skid shoe.

• Return weight transfer lever to normal position before adjusting skid shoes.

• For close snow removal, adjust skid shoes higher to minimize gap between the shave plate and the ground.

• For snow removal from uneven ground like gravel, adjust skid shoes downward to create sufficient clearance between the bottom edge of the shave plate and the ground. See Figure 16.

NOTE: It is not recommended that you operate this snow thrower on gravel as loose gravel can be easily picked up and thrown by the auger causing an injury or damage to the snow thrower. However, if you do have to use the snow thrower on gravel, put the weight transfer lever to transport position.

• Adjust skid shoes by loosening the four hex nuts and carriage bolts and moving skid shoes to desired position. Make certain the entire bottom surface of skid shoe is against the ground to avoid uneven wear on the skid shoes. See Figure 16.

• Retighten nuts and bolts securely.

Before Starting Engine

Fill Gas

WARNING: Gasoline is flammable and cau-

tion must be used when handling or storing it.

Do not fill fuel tank while the snow thrower is running, when it is hot or when it is in an enclosed area.

Keep your snow thrower away from any open flame or an electrical spark and do not smoke while filling the fuel tank.

Never fill the fuel tank completely. Fill the tank to within 1/4"-1/2" from the top to provide space for expansion of fuel.

Always fill the fuel tank outdoors and use a funnel or spout to prevent spilling.

Make sure to wipe off any spilled fuel before starting the engine.

• Store gasoline in a clean, approved container and keep the cap in place on the container.

• Make sure that the container from which you pour the gasoline is clean and free from rust or other foreign particles.

• Fill fuel tank with clean, fresh, unleaded grade automotive gasoline.

• At the end of the job, empty the fuel tank if the snow thrower is not going to be used for 30 days or longer. See storage instructions on page 24 of this manual.

CAUTION: Experience indicates that alcohol blended fuels (called gasohol) or those using ethanol or methanol can attract moisture which leads to separation and formation of acids during storage.

Acidic gas can damage the fuel system of an engine while in storage.

To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See storage Instructions for additional information.

Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

Cold Start

NOTE: If the unit shows any sign of motion (drive or

augers) with the clutch grips disengaged, shut the engine off immediately. Readjust as instructed in the “Final Adjustments” section on page 11.

WARNING: The electric starter must be properly grounded at all times to avoid possibility of electric shock which may injure the operator.

• Determine whether your house wiring is a threewire grounded system. Ask a licensed electrician if you are not certain.

WARNING: If your house wiring system is not a three-wire grounded system, do not use this electric starter under any conditions.

• If your house wiring system is grounded and a three-hole receptacle is not available at the point the snow thrower starter will normally be used, one should be installed by a licensed electrician.

• When connecting the power cord, always connect cord to starter on engine first, then the other end into a three-hole grounded receptacle.

• When disconnecting the power cord, always unplug the end from the three-hole, grounded receptacle first.

• Attach spark plug wire to spark plug.

• Make sure that the auger drive and the traction

drive levers are in the disengaged RELEASED position.

• Move throttle control lever to FAST position.

• Remove the keys from the plastic bag. Push key

into the ignition slot. Make sure it snaps into place. Do not turn key. Save the second key.

• Rotate the choke knob to FULL choke position.

• Connect power cord to switch box on engine.

• Plug the other end of the power cord into a

three-hole, grounded 120 volt A.C. receptacle.

WARNING: Do not use primer while starting the engine with an electric starter.

• Push down on the starter button until the engine starts. Do not crank for more than 10 seconds at a time. This electric starter is thermally protected. If overheated, it will stop automatically and can be restarted only when it has cooled to a safe temperature (a wait of about 5 to 10 minutes is required).

• When the engine starts, release the starter button and slowly rotate the choke to OFF position. If the engine falters, rotate the choke to FULL and then gradually to OFF.

• Disconnect the power cord from the receptacle first and then from the switch box on the engine.

• Allow the engine to warm up for a few minutes because the engine will not develop full power until it reaches operating temperature.

• Operate the engine at full throttle (FAST) when throwing snow.

Warm Start

• If restarting a warm engine after a shut down, rotate choke to OFF instead of FULL and press the starter button.

B. Recoil Starter

Make sure that the engine has sufficient oil and the auger drive and the traction drive levers are released.

• Move throttle control to FAST position.

• Push key into the ignition slot so that it snaps

into place. Do not turn key. Remove plastic bag and keep the second key in a safe place.

• Rotate choke control to FULL choke position.

• Push the primer button while covering the vent

hole. Remove your finger from the primer between primes. Do not prime if temperature is above

F; prime two times between 50o F and 15o F;

and prime four times below 15

• Pull the starter handle rapidly. Do not allow the handle to snap back, but allow it to rewind slowly while keeping a firm hold on the starter handle.

• As the engine warms up and begins to operate evenly, rotate the choke knob slowly to OFF position. If the engine falters, return to FULL choke, then slowly move to OFF choke position.

• Allow the engine to warm up for a few minutes because the engine will not develop full power until it reaches operating temperature.

• Operate the engine at full throttle (FAST) when throwing snow.

Warm Start

• If restarting a warm engine after a temporary shut down, rotate choke to OFF instead of FULL and do not prime. Press the starter button.

Frozen Recoil Starter

If the starter is frozen and will not turn the engine, proceed as follows:

• Pull as much rope out of the starter as possible.

• Release the starter handle and let it snap back

against the starter.

• If the engine still fails to start, repeat the first two steps. If continued attempts do not free starter, follow the electric starter procedures to start.

• Avoid possible freezing of recoil starter and the engine controls.

Operating Snow Thrower

To Engage Drive

• With the engine running near top speed, move shift lever to one of six FORWARD positions or two REVERSE positions. Select a speed appropriate for the snow conditions that exist.

Use slower speeds until you are familiar with the operation of the snow thrower.

• Squeeze the traction drive clutch grip against the right handle and the snow thrower will move. Release it and the drive motion will stop.

To Engage Augers

• To engage augers and start snow throwing, squeeze the left hand auger clutch grip against the left handle. Release to stop augers.

• While the auger control is engaged, squeeze the traction drive control to move, release to stop. Do

not shift speeds while the drive is engaged.

NOTE: This same lever also locks the auger control so

you can turn the chute crank without interrupting the snow throwing process.

• Release the auger control; the interlock mechanism should keep the auger control engaged until the traction drive control is released.

• Release the traction drive control to stop both the augers and the track drive.

WARNING: To stop the auger, both levers must be released.

To Throw Snow

CAUTION: Check the area to be cleared for foreign

objects. Remove, if any.

• Move weight transfer lever to the right, then backward or forward to the desired position.

• Start the engine following Starting Instructions.

• Rotate the discharge chute to the desired

direction, away from bystanders and/or buildings. Move the chute distance control forward or backward to adjust the distance the snow is to be thrown.

• Select the speed according to the snow condition.

CAUTION: Never move the shift lever without first releasing the drive clutch.

• Engage the auger control and traction drive control levers following the preceding instructions.

• The interlock feature will allow you to remove your left hand from the auger control lever.

• When clearing the first pass through the snow, control the traction speed of the snow thrower according to the depth and condition of snow.

• To turn the unit left, squeeze left trigger; to turn right, squeeze right trigger.

• On each succeeding pass, readjust the chute deflector to the desired position and slightly overlap the previously cleared path.

• After the area is cleared, stop the snow thrower following instructions given below.

Operating Tips

NOTE: Allow the engine to warm up for a few minutes

as the engine will not develop full power until it reaches operating temperature.

Warning: The temperature of muffler and surrounding areas may exceed 150

these areas.

• For most efficient snow removal, remove snow immediately after it falls.

• Discharge snow downwind whenever possible. Slightly overlap each previous swath.

• Set the skid shoes 1/4" below the scraper bar for normal usage. The skid shoes may be adjusted upward for hard-packed snow. Adjust skid shoes downward when using on gravel or crushed rock.

• Clean the snow thrower thoroughly after each use.

F. Avoid

Before Stopping

• Run engine for a few minutes to help dry off any moisture on engine.

• To avoid possible freeze-up of the starter, follow these steps:

Recoil Starter

a. With the engine running, pull the starter rope

with a rapid, continuous full arm stroke three or four times.

Electric Starter

a. Connect power cord to switch box, then to

120 Volt AC receptacle.

b. While the engine is running, push the starter

button and spin the starter for several seconds.

c. Disconnect power cord from the receptacle

first, then from the snow thrower.

NOTE: The unusual sound from pulling the starter rope in the case of the recoil starter, or from spinning the starter in the case of the electric starter, will not harm the engine.

To Stop The Snow Thrower

• To stop the track, release the traction drive lever on the snow thrower.

• To stop throwing snow, release auger drive lever and drive lever, if engaged.

• To stop the engine, push throttle control lever to OFF and pull out the ignition key. Do not turn key.
