SERVICE AND MAINTENANCE

Checking Spark Plug

Check spark plug yearly or every 100 operating hours

Clean area around spark plug.

1. Remove and inspect spark plug.

2. Replace spark plug if porcelain is cracked or if electrodes are

3. pitted, burned or fouled with deposits

Check electrode gap with a feeler gauge and set gap to .030

4. (0.76mm) if necessary. See Figure 14.

Reinstall spark plug and tighten securely.

NOTE: A resistor spark plug must be used for replacement. Contact a Sears Parts and Repair Center for a replacement spark plug.

Carburetor

If you suspect your carburetor needs adjusting, see a Sears Parts and Repair Center. Engine performance should not be affected at altitudes up to 7,000 feet (2,134 meters). For operation at higher elevations, contact a Sears Parts and Repair Center.

Engine Speed

WARNING

Avoid serious injury or death, DO NOT modify engine in any way. Tampering with the governor setting can cause the engine and equipment to operate at unsafe speeds. NEVER tamper with factory setting of engine governor. Running the engine faster than the speed set at the factory is dangerous.

LUBRICATION

Gear Shaft

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

Carefully pivot the snow thrower up and forward so that it rests on

1. the auger housing.

Remove the lower frame cover from the underside of the snow

2. thrower by removing the four self-tapping screws which secure it.

Apply a light coating of engine oil (or 3-in-1 oil) to the hex shaft.

3. See Figure 15.

NOTE: When lubricating the hex shaft, be careful not to get any oil on the aluminum drive plate or rubber friction wheel. Doing so will hinder the snow thrower’s drive system. Wipe off any excess or spilled oil.

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

Once a season, lubricate the eye bolt bushing and the spiral with 3-in-1 oil.

Auger Shaft

At least once a season, remove the shear pins on auger shaft. Spray lubricant inside shaft, and around the spacers and flange bearings found at either end of the shaft. See Figure 16.

SERVICE AND MAINTENANCE

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:

Remove the four carriage bolts and hex flange nuts which secure

1. them to the snow thrower.

Reassemble new skid shoes with the four carriage bolts (two on

2. each side) and hex flange nuts. Refer to Figure 17.

To remove shave plate:

Remove the carriage bolts and hex nuts which attach it to the

1. snow thrower housing.

Reassemble new shave plate, making sure heads of carriage

2. bolts are to the inside of housing. Tighten securely.

ADJUSTMENTS

Drive Control

When the drive control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight. Also, if there is excessive slack in the drive cable or if the unit experiences intermittent drive while using, the cable may need to be adjusted. Check the adjustment of the drive control as follows:

With the drive control released, push the snow thrower gently

1. forward. The unit should roll freely.

Engage the drive control and gently attempt to push the snow

2. thrower forward. The wheels should not turn. The unit should not roll freely.

With the drive control released, move the shift lever back and

3. forth between the R2 position and the F5 position several times. There should be no resistance in the shift lever.

If any of the above tests failed, the drive cable is in need of adjust-

4. ment. Proceed as follows:

Loosen the lower hex nut on the drive cable bracket. See Figure

18. Position the bracket upward to provide more slack (or downward

6. to increase cable tension).

Retighten the lower hex nut.
