Section 5: Maintenance

Lubrication

At the beginning and end of each season or after every 25 hours of operation, lubricate the unit as recommended below:

1.Lightly oil both the deflector chute cap pivot points (D, Fig. 5-3).

2.Lightly oil the discharge chute control rod pivot points where the control rod enters the control panel bearing

(E, Fig. 5-4), the support tab

(F, Fig. 5-4), and the support on the left rear of unit housing (G, Fig. 5-6).

3.Remove the left wheel (H, Fig. 5-3). Clean the wheel shaft and apply multi- purpose grease to the wheel shaft. Reinstall the left rear wheel.

4.Apply oil to the bearings on sides of the auger shaft (J, Fig. 5-3).

5.Clean dirt and old grease from the flange at the bottom of the discharge chute (K, Fig. 5-3). Apply multi-purpose grease to the worm gear (C), toothed portion of flange and the flange.

6.Lightly lubricate the handlebar control levers at pivot points (M, Fig. 5-4) with oil or a non-silicone spray. Do not get oil or lubricating spray on levers.

7.Lightly oil the pivot points on the gear shift control lever (N, Fig. 5-4).

8.Remove the two shear bolts (C, Fig. 5-

7)from the auger shaft, then lubricate the four auger grease fittings (O, Fig. 5-7) using a grease gun. Rotate auger three or four times. Reinstall shear bolts, torque to 11 ft-lbs (15Nm).

9.Check the auger gear case oil level :

a.Place the unit on a smooth, level surface. Unscrew the plug

(P, Fig. 5-7) from the front of gear case.

b.Inspect plug hole. Oil should just begin to seep out of the hole. Add SAE 90 gear oil if necessary until oil just begins to flow out of hole. Let the excess oil drain out of the gear case.

c.Reinstall the plug (P).

multi-purpose grease to the shafts (R

and S, Fig. 5-5). Prevent grease from

contacting rubber drive wheel (T) or

drive disk (U). If grease should contact

these parts, wipe clean to avoid

slippage and assure proper operation.

Move shift lever between high speed

and reverse settings to spread grease

along shafts. Replace bottom cover.

Wheel Drive Disc Adjustment

Due to wear, the wheel drive control disc may begin to slip when wheel drive lever is engaged. To adjust wheel drive disc:

1.Pull the wheel drive control arm (V, Fig. 5-6) down completely.

2.Measure and note the distance between the coiled ends of the spring (W, Fig, 5-6).

3.Squeeze wheel drive control lever (X, Fig. 5-3) against handlebar. Measure
