Lubrication

Engine

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

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.

Augers

The augers are secured to the spiral shaft with shear pins and cotter pins. See Figure 6-2. If you hit a foreign object or ice jam, the snow thrower is designed so that the pins will shear.

1.If augers do not turn, check to see if 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

Avoid oil spillage on rub- ber friction wheel and aluminum drive plate.

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.
