SHIFT ROD ADJUSTMENT

To adjust the shift rod, remove the cotter pin which secures the shift rod to the shift lever. For proper adjustment, refer to FINAL ADJUSTMENTS on page 6.

SKID SHOE ADJUSTMENT

The space between the shave plate and the ground can be adjusted. Refer to Skid Shoe Adjustment (See Figure 8) on page 6.

CARBURETOR ADJUSTMENT

WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and mufflers.

Minor carburetor adjustment may be required to compensate for differences in fuel, temperature, altitude and load.

Refer to the separate engine manual packed with your unit for carburetor adjustment information.

NOTE: Failure to comply with suggested maintenance and lubrication specifications on pages 10 and 11 will void warranty.

SECTION 8: LUBRICATION

WHEELS

Oil or spray lubricant into bearings at wheels at least once a season. Remove wheels, clean and coat axles with a multi-purpose automotive grease. See Figure 15.

CHAINS AND SHIFTING MECHANISM

Remove lower cover. Oil all chains, sprockets, bearings, the hexagonal shaft, round shaft, and shifting mechanism at least once a season. Use engine oil or a spray lubricant. Avoid getting oil on rubber friction wheel and aluminum drive plate.

CHUTE DIRECTIONAL CONTROL WORM

The worm gear on the chute directional crank should be greased with multi-purpose automotive grease.

HEX SHAFT

Lubricate the hex shaft with a good all-weather multi- purpose light grease at least once a season or after every 25 hours of operation (available from an authorized service dealer or an automotive store.) See Figure 15.

If for any reason your transmission was disassembled and the auger cable disconnected, make sure when reassembling to pass the cable above the hex shaft before reconnecting to the auger actuator bracket.

WARNING: When following instruc- tions in separate engine manual for draining oil, be sure to protect frame to avoid oil dripping onto transmission parts.

IMPELLER PULLEY

The impeller pulley should be lubricated once a season. Refer to exploded view of parts, found in the back of the book, for correct location.

AUGER SHAFT

Remove auger bolts on auger shaft, see Figure 16. Oil or spray lubricant inside shaft.

ENGINE

Refer to engine manual for engine lubrication instructions.
