SAFE OPERATION PRACTICES SAFE HANDLING OF GASOLINE To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately. OPERATION 1. Do not put hands or feet near rotating parts, in the auger housing or chute assembly. Contact with the rotating parts can amputate hands and feet. 2.
SAFE OPERATION PRACTICES 17. Disengage all control levers, stop engine, remove the safety key or disconnect spark plug wire before you leave the operating position (behind the handles). Wait until the auger comes to a complete stop before unclogging the chute assembly, making any adjustments, or inspections. 5. Snow blower shave plates and skid shoes are subject to wear and damage.

Secure chute control head to chute support bracket with clevis pin (d) and bow-tie cotter pin (e) removed in Step 1 (Figure 31).
ASSEMBLY 6. Push chute control rod toward the control panel until hole in rod lines up with middle hole in chute control coupler and insert hairpin clip (a) removed in Step 1 (Figure 34). c a a c Figure 34 NOTE: There is a reference hole provided at rear end of control rod to help know when holes are vertical. NOTE: Hole furthest from chute control head is used to achieve further engagement of chute control rod into coupler, if required. Refer to Adjustments, Overhead Chute Control on page 15.
ASSEMBLY SKID SHOES (IF APPLICABLE) Select models require the installation to the provided skid shoes. DRIFT CUTTERS (IF EQUIPPED) The drift cutters are mounted inverted at the factory for shipping purposes. 1. Using the two carriage bolts (a) and hex flange nuts (b) and flat washers (if equipped) (c), secure the skid shoes to the auger housing (d). Hand tighten hex flange nuts (Figure 39). Non-Adjustable 1.
ADJUSTMENTS b b OVERHEAD CHUTE CONTROL (IF EQUIPPED) If chute fails to remain stationary during operation, preload of chute can be adjusted by tightening hex nut found on front of chute control head. 1. To increase preload, tighten hex nut (a) clockwise in ¼ turn intervals. The chute control rod (b) will need to be held stationary when tightening the nut (Figure 44).
ADJUSTMENTS 7. To readjust the auger control cable, loosen upper hex screw (a) (Figure 47). a a a b b b b b d c c c c Figure 47 8. Position auger control bracket (b) upward to provide more slack in cable (Figure 47). Figure 46 NOTE: 3-Stage model shown. 9. Re-tighten upper/rear hex screw (a). 4. Adjust the shave plate to one of 2 mounting positions. Reinstall and securely tighten all carriage bolts, nuts and skid shoe hardware from Step 3 (Figure 46). 10.
ADJUSTMENTS SHIFT ROD (IF EQUIPPED) If full range of speeds (forward and reverse) cannot be achieved, adjust shift rod as follows: 1. Place shift lever in fastest forward speed position. 2. Remove hairpin clip (a) and washer (b) from adjustment ferrule on shift rod and pull it out from shift lever (Figure 49). DRIVE CONTROL (IF EQUIPPED) When drive control lever is released and in disengaged “UP” position, cable should have very little slack. It should NOT be tight.
