WARNING: The optional electric starter is equipped with a grounded three-wire power cord and plug, and is designed

to operate on 120 volt AC household current. It must be used with a properly grounded three-prong receptacle at all times to avoid the possibility of electric

shock. Follow all instructions carefully prior to operating the electric starter.

If you have a grounded three-prong receptacle, proceed as follows:

1. Plug the extension cord into the outlet located on the engine’s surface. Plug the other end of extension cord into a three-prong 120-volt, grounded, AC outlet in a well-ventilated area.

2. Rotate choke control to FULL choke position (for a cold engine start).

6. As the engine warms, slowly rotate the choke control to the OFF position. If the engine falters, quickly rotate the choke control back to FULL and then slowly into the OFF position again.

7. When disconnecting the extension cord, always unplug the end at the three-prong wall outlet before unplugging the opposite end from the snow thrower.

Recoil Starter

1. Rotate choke control to FULL choke position (cold engine start).

NOTE: If the engine is already warm, place choke control in the OFF position instead of FULL.

2. Push the primer two or three times for cold engine start, making sure to cover vent hole in the center of the primer when pushing.

NOTE: DO NOT use primer to restart a warm engine after a short shutdown.

NOTE: Additional priming may be necessary if the temperature is below 15° F. (-9° C).

3. Grasp the recoil starter handle and slowly pull the rope out. At the point where it becomes slightly harder to pull the rope, slowly allow the rope to recoil.

4. Pull the starter handle with a firm, rapid stroke. Do not release the handle and allow it to snap back. Keep a firm hold on the starter handle and allow it to slowly recoil.

5. As the engine warms, slowly rotate the choke control to the OFF position. If the engine falters, quickly rotate the choke control back to the FULL position and then slowly into the OFF position again.

NOTE: Allow the engine to warm up for a few minutes after starting. The engine will not develop full power until it reaches operating temperatures.

If your home electrical system is grounded, but a three-hole receptacle is not available, do not use your snow thrower’s electric starter.

NOTE: If the engine is already warm, place choke control

in the OFF position instead of FULL.

3. Push the primer two or three times for cold engine start, making sure to cover vent hole in the center of the primer when pushing.

NOTE: DO NOT use primer to restart a warm engine after a short shutdown.

4. Push starter button to start engine.

1. To engage augers and start snow throwing, squeeze the left hand auger control against the left handle. Release to stop augers.

2. While the auger control is engaged, squeeze the drive control to move, release to stop. Do not shift speeds while the drive is engaged.

Auger Control Test

Perform the following test before operating your snow thrower for the first time and at the start of each winter. Check the adjustment of the auger control as follows:

1. When the auger control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight.

2. In a well-ventilated area, start the snow thrower engine as instructed on the previous page. Make sure the throttle is set in the FAST position.

3. While standing in the operator’s position (behind the snow thrower), engage the auger.

4. Allow the auger to remain engaged for approximately ten (10) seconds before releasing the auger control. Repeat this several times.

5. With the throttle control in the FAST (rabbit) position and the auger control in the disengaged “up” position, walk to the front of the machine.

6. Confirm that the auger has completely stopped rotating and shows NO signs of motion. If the auger shows ANY signs of rotating, immediately return to the operator’s position and shut off the engine. Wait for ALL moving parts to stop before re-adjusting the auger control.

7. To readjust the control cable, loosen the upper hex nut on the auger cable bracket. See Figure 4-2.

8. Position the bracket upward to provide more slack (or downward to increase cable tension).

9. Retighten the upper hex nut.

10. Repeat Auger Control Test to verify proper adjustment has been achieved.

WARNING

The muffler, engine and surrounding areas become hot and can cause a burn 150°F (65°C). Do not touch.

When selecting a Drive Speed, use the slower speeds until you are comfortable and familiar with the operation of the snow thrower.

NEVER reposition the shift lever (change speeds or direction of travel) without first releasing the drive control and bringing the snow thrower to a complete stop. Doing so will result in premature wear to the snow thrower’s drive system.

NOTE: This same lever also locks auger control so you

can turn the chute control without interrupting the snow throwing process.

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

4. Release the drive control to stop both the augers and the wheel drive. To stop the auger, both levers must be released.

The space between the skid shoes and the ground can be adjusted.

• For close snow removal on a smooth surface, raise skid shoes higher on the auger housing.

• Use a middle or lower position when the area to be cleared is uneven, such as a gravel driveway.

To adjust the skid shoes:

1. Loosen the four hex nuts (two on each side) and carriage bolts. Move skid shoes to desired position.

2. Make certain the entire bottom surface of skid shoe is against the ground to avoid uneven wear on the skid shoes.

3. Retighten nuts and bolts securely.

NOTE: Some models are equipped with reversible skid shoes and may be turned over to increase their lifespan. See Figure 5-7 and 5-8.

WARNING

Loose gravel can be picked up and thrown by the auger, causing injury to the operator and bystanders and/or damage to the snow thrower and surrounding

property.

Chute Bracket Adjustment

If the spiral at the bottom of the chute directional control is not fully engaging with the chute assembly, the chute bracket can be adjusted. To do so:

1. Loosen the two nuts which secure the chute bracket and reposition it slightly. See Figure 5-9.

2. Retightening the nuts.

Tire Pressure

Before operating, check tire pressure and reduce pressure to between 15 psi and 20 psi. If the tire pressure is not equal in both tires, the unit may not travel in a straight path and the shave plate may wear unevenly.

WARNING

Before lubricating, repairing, or inspecting, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop.

Lubrication

Engine

Refer to the separate engine manual packed with your unit for all engine lubrication instructions.

Gear Shaft

The gear (hex) shaft should be lubricated at least once a season or after every 25 hours of operation.

1. Carefully pivot the snow thrower up and forward so that it rests on the auger housing.

2. Remove the lower frame cover by removing the two screws which secure it.

3. Apply a light coating of an all-weather multi-purpose oil to the hex shaft. See Figure 6-1.

NOTE: Avoid getting oil on rubber friction wheel and aluminum drive plate.

Wheels

At least once a season, remove both wheels. Clean and coat the axles with a multipurpose automotive grease before reinstalling wheels.

Chute Directional Control (optional)

Once a season, the joystick should be lubricated with petroleum jelly, linseed oil, mineral oil, paraffin wax or 3-in-1 oil.

Auger Shaft

At least once a season, remove the shear pins on auger shaft. Spray lubricant inside shaft, around the spacers. Also lubricate the flange bearings found at either end of the shaft. See Figure 6-2.

Keep all grease and oil off of the rubber friction wheel and aluminum drive plate.

Shave Plate and Skid Shoes

The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. They should be checked periodically and replaced when necessary. To remove skid shoes:

1. Remove the four carriage bolts and hex flange nuts which secure them to the snow thrower.

2. Reassemble new skid shoes with the four carriage bolts (two on each side) and hex flange nuts. Refer to Figure 6-3.

To remove shave plate:

1. Remove the carriage bolts and hex nuts which attach it and the skid shoes to the snow thrower housing.

2. Reassemble new shave plate, making sure heads of carriage bolts are to the inside of housing. Tighten securely.

Auger Belt Replacement

To remove and replace your snow thrower’s auger belt, proceed as follows:

1. Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. See Figure 6-4.

Figure 6-4

NOTE: Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap.

2. Carefully pivot the snow thrower up and forward so that it rests on the auger housing. Remove the frame cover from the underside of the snow thrower by removing four self-tapping screws which secure it. See Figure 6-5.

3. Roll the auger belt off the engine pulley. See Figure 6-6.

4. a. Loosen and remove the shoulder screw which

acts as a belt keeper. See Figure 6-7.

b. Unhook the support bracket spring from the

frame.

5. Remove the belt from around the auger pulley, and slip the belt between the support bracket and the auger pulley. Reassemble auger belt by following instructions in reverse order. See Figure 6-8.

NOTE: Do NOT forget to reinstall the shoulder screw and reconnect the spring to the frame after installing a replacement auger belt and to remove the piece of plastic from under the gas cap.

Maintaining

Your Snow

Thrower

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multiviscosity oils also result in higher oil consumption when used above 32ºF (0ºC). Check your snow thrower’s engine oil level more frequently to avoid possible engine damage from running low on oil.

NOTE: Do not sandblast spark plug. Spark plug should be cleaned by scraping or wire brushing and washing with a commercial solvent.

IMPORTANT

NEVER replace the auger shear pins with standard pins. Any damage to the auger gearbox or other components, as a result of doing so, will NOT be covered by your snow thrower’s warranty.

NEVER replace the auger shear pins with standard hex pins. Any damage to the auger gearbox or other components as a result of failing to do so will NOT be covered by your snow thrower’s warranty.

Figure 6-9

Augers

• The augers are secured to the spiral shaft with two shear pins and cotter pins. If the auger should strike a foreign object or ice jam, the snow thrower is designed so that the pins may shear. Refer to Figure 6-9.

• If the augers will not turn, check to see if the pins have

sheared. One set of replacement shear pins has been provided with the snow thrower. When replacing pins, spray an oil lubricant into shaft before inserting new pins.

Drive Belt Replacement

To remove and replace your snow thrower’s auger belt, proceed as follows:

1. Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. See Figure 6-9.
