Changing Oil
Change engine oil after first two hours of operation and every 25 hours
thereafter.
In order to change oil, you will have to first drain the used engine oil
from the engine and then refill with fresh oil.
1. Drain oil while engine is warm. Remove oil drain plug located at
the bottom of the recoil starter of the engine. Catch oil in a suitable
container.
2. When engine is drained of all oil, replace drain plug securely.
3. Remove the dipstick from the oil fill. Pour fresh oil slowly through
the plug. Replace dipstick.
4. Check and make sure that the level of oil is up to the FULL mark on
the dipstick.
NOTE: Although multi-viscosity oils (5W30, 10W30, etc.) improve
starting in cold weather, they could also result in higher oil consumption when used above 32˚ F. Check your snow thrower’s engine oil
level more frequently to avoid possible engine damage from running
low on oil.
Check Chute Cables
Once a season or every 25 hours of operation, whichever is earlier,
check whether chute cables have slackened. Adjust if necessary,
following instructions on page 17.
Check Augers
The augers are secured to the spiral shaft with two shear pins and
cotter pins. See Figure 10. If you hit a foreign object or ice jam, the
snow thrower is designed so that the pins may shear.
1. If the augers do not turn, check to see if the pins have sheared.
2. Replace the pins if needed. Two replacement shear pins and
cotter pins have been provided with the snow thrower. Spray an oil
lubricant into shaft before inserting new pins and securing with new
cotter pins.
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.
Check Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the snow thrower are
subject to wear. Check these periodically and replace as necessary.
Replacing Skid Shoe
1. Remove four carriage bolts and lock nuts which attach two skid
shoes to the snow thrower on two sides. See Figure 12.
Check Spark Plug
Check spark plug yearly or every 100 operating hours.
1. Clean area around the spark plug base.
2. Remove and inspect the spark plug.
3. Replace the spark plug if electrodes are pitted, burned, fouled with
deposits or the porcelain is cracked.
4. Check electrode gap with a feeler gauge and set gap to .030
(0.76mm) if necessary.
NOTE: A resistor spark plug must be used for replacement. Contact a
Sears Parts and Repair Center for a replacement spark plug.
Figure 12
2. Reassemble new skid shoes with the same hardware. Make certain
the skid shoes are adjusted to be level.
Replacing Shave Plate
1. After removing both skid shoes, remove four carriage bolts and lock
nuts which attach shave plate to the snow thrower housing. See
Figure 12.
2. Reassemble new shave plate, making sure heads of the carriage
bolts are to the inside of the housing. Tighten securely. Re-install
skid shoes.

Adjustments
WARNING: Never attempt to clean chute or make
any adjustments while engine is running.
Auger Control
To adjust the auger control, refer to Auger Control Test, on page 12.
Shift Cable
If the full range of speeds (forward and reverse) cannot be achieved,
refer to the figure to the left and adjust the shift cable as follows:
1. Place the shift lever in the fastest forward speed position.
2. Loosen the hex nut on the shift cable index bracket. See Figure 20.
3. Pivot the bracket downward to take up slack in the cable.
4. Retighten the hex nut.
5. Check for correct adjustment before operating the snow thrower.
Chute Control
Once a season or every 25 hours of operation, whichever is earlier,
check whether the four-way chute control™ cables have slackened. If
the chute does not rotate fully or its pitch cannot be moved up or down,
the chute control cables will have to be adjusted.
To adjust these cables, proceed as follows:
1. To tighten cable, loosen the top nut and tighten the bottom nut on
the cable.
2. Adjust equally on both sides by working on both cables. See Figure
21.
Figure 21

SERVICE & 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.
Check the adjustment of the drive control as follows:
1. With the drive control released, push the snow thrower gently
forward. The unit should roll freely.
2. Engage the drive control and gently attempt to push the snow
thrower forward. The wheels should not turn. The unit should not
roll freely.
3. With the drive control released, move the shift lever back and forth
between the R2 position and the F6 position several times. There
should be no resistance in the shift lever.
4. If any of the above tests failed, the drive cable is in need of adjust
ment. Proceed as follows:
5. Loosen the lower hex nut on the drive cable bracket. See Figure 22.
6. Position the bracket upward to provide more slack (or downward to
increase cable tension).
7. Retighten the lower hex nut.
Skid Shoes
The space between the skid shoes and the ground can be adjusted.
See Figure 23.
• 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.
