SERVICE AND MAINTENANCE

3.Measure the plug gap with a feeler gauge. Correct as necessary by bending side electrode. See Figure 15. The gap should be set to .02-.03 inches (0.60-0.80 mm).

4.Check that the spark plug washer is in good condition and thread the spark plug in by hand to prevent cross-threading.

5.After the spark plug is seated, tighten with a spark plug wrench to compress the washer.

NOTE: When installing a new spark plug, tighten 1⁄2-turn after the spark plug seats to compress the washer. When reinstalling a used spark plug, tighten 1⁄8- to 1⁄4-turn after the spark plug seats to compress the washer.

CAUTION

The spark plug must be tightened securely. A loose spark plug can become very hot and can damage the engine.

LubricationGear Shaft

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

1. To prevent spillage, remove all fuel from tank by running engine until it stops.

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

the auger housing.

3. Remove the lower frame cover from the underside of the snow thrower by removing the four self-tapping screws which secure it.

4. Apply a light coating of engine oil (or 3-in-1 oil) to the hex shaft. See Figure 16.

	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	Figure 16
	with a multipurpose automotive grease before reinstalling wheels.	Figure 16

	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 17.
