Fuel Shut-Off Valve IMPORTANT: The fuel shut-off valve MUST be in the closed position prior to transporting the unit. The fuel shut-off valve 1 has two positions: Open (1): Use this position to run the unit. Closed (2): Use this position to service, transport, or store the unit. 2 PRE-START 1. Frozen Impeller IMPORTANT: Before starting engine, check impeller to be sure it is not frozen. To check impeller: 1. With ignition key switch in "Stop" position, squeeze Attachment Clutch Lever to Engaged position. 2. Pull Recoil Starter Handle. 3. If Impeller is frozen, (cannot pull Starter Handle) move unit to a heated area and thaw to prevent possible damage. 2.

See Attachment Clutch/Brake Adjustment on page 25 and Traction Drive Clutch Adjustment on page 27. 3. Check Dual Handle Interlock Without the engine running, press down (engage) both clutch levers. Release attachment clutch lever. Attachment clutch should remain engaged until traction clutch lever is released, then both clutches must disengage.

Check Axle Lock (926056) Use the axle lock knob to lock or unlock the right side differential. Lock the differential to engage both tracks and increase traction; unlock the right side to allow for easier turning of the unit (see Differential Lock on page 15). 5. Check Skid Shoes Check and adjust Skid Shoes (See Skid Shoes on page 23). Allow 1/8 in. (3 mm) between scraper blade and hard, smooth surface(s). Allow 7/8 in.

STARTING AND SHUT OFF WARNING: FAILURE TO FOLLOW INSTRUCTIONS could result in personal injury and/or damage to unit. DO NOT attempt to start your unit at this time. Read entire Owner/Operator Manual and the Engine Manual first. IMPORTANT: Allow unit and engine to adjust to the outdoor temperature before clearing snow. Before shut-off, run the attachment a few minutes to prevent impeller freeze-up. NOTE: Try out each control without the engine running to see how it works and what it does. Manual Start 1. Turn discharge chute straight ahead. 2. Make sure that the traction clutch and attachment drive clutch levers are fully disengaged. 3. Push Primer Bulb 2 or 3 times for cold engine.
