	washers (AB, Figure 5-1) and remove
	belt cover from unit.
2.	Squeeze the auger drive control lever
	(AL, Figure 5-7) against handlebar.
3.	Using a flashlight, look down through
	the pulleys and belts (Figure 5-6).
	Check gap between brake arm (A,
	Figure 5-11) and belt (B). The gap
	should measure between 1/16" and
	1/8" (1.5–3 mm).
4.	To adjust gap: Loosen nut (C, Figure
	5-11). Hold bolt (D) in place and rotate
	nut (E) until proper clearance is ob-
	tained. Secure nut (C).
5.	Reinstall the belt cover.

SKID SHOES/SCRAPER BLADE

The unit should be adjusted so the collec- tor (auger/impeller) housing and the scraper blade (N, Figure 5-12) are 1/8" (3

mm)above the surface to be cleared. If the unit is used to clear gravel or uneven surfaces, this adjustment should be in- creased so gravel or other foreign objects are not scooped into the auger. To adjust the collector housing/scraper blade height:

1.Move the unit onto a level surface.

2.With the engine stopped and the spark plug wire disconnected, loosen the hardware securing the skid shoes (M, Figure 5-12).

3.Adjust skid shoes until they are in the correct position to support collector (auger/impeller) housing and scraper

blade (adjust both skid shoes equally to prevent uneven snow removal).

4.Tighten the hardware to lock the skid shoes (M, Figure 5-12) into the proper position.

5.The scraper blade (N, Figure 5-12) can also be adjusted. Adjust scraper blade

(N) at carriage bolts. Adjust bottom edge of scraper blade so it is parallel with bottom edge of auger.

SLIP DIFFERENTIAL

ADJUSTMENT

1.With the engine stopped and the spark plug wire disconnected, remove hub cap (AQ, Figure 5-13) at end of wheel shaft on right side of unit.

2.Remove outer (AR, Figure 5-13) and inner jam nuts (AS) and both pairs (four single disc springs) of disc springs (AT). Inspect springs and re- place them if they are worn.

3.Reinstall disc springs (AT, Figure 5- 13) and inner jam nut (AS). Tighten jam nut (AS) by hand until it contacts the disc spring, then tighten (AS) 1 to 1-1/4 turns more. DO NOT force nut more than 1-1/4 turns or differential will not work (unit will be difficult to turn).

4.Secure the inner nut (AS, Figure 5-13) in place, while tightening the outer nut (AR).

5.Reinstall cover (AQ, Figure 5-13).

When storing the unit for more than 90 days, follow these procedures to help keep the unit in good condition for future use:

•Clean dirt, grime and grease from the unit and engine.

•Perform routine lubrication as in- structed earlier in this section.

•Service the engine according to the Storage instructions in the engine manual. Add a fuel stabilizer to the fuel tank, according to the instructions provided with the stabilizer. Change the engine oil.

•On units so equipped, rotate the fuel shut-off valve to the “OFF” position.

•Thoroughly inspect the unit for any loose, damaged, or missing parts. Repair or replace the parts as neces- sary. Check all nuts, bolts and other fasteners for tightness and tighten as necessary.

•Touch-up scratches and chipped paint to prevent corrosion.

•Store the unit on a level surface, out of the reach of children.
