Scraper Blade

The scraper blade allows the back of the housing to keep better contact with the surface being cleared. It also prevents damage to the housing from normal wear.

IMPORTANT: DO NOT allow Scraper Blade to wear too far or Auger/Impeller housing will become damaged.

Runners

The runners control the distance between the scraper blade and the ground. Adjust runners equally to keep blade level with the ground. Refer to Pre-Starton page 12 for recommended settings.

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.Check Function of Clutches

If clutches do not engage or disengage properly, adjust or repair before operation. See Attachment Clutch/Brake Adjustment on page 19 and Traction Drive Clutch Adjustment on page 21

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.

If clutches do not engage or disengage properly, adjust or repair before operation (see Attachment Clutch/Brake Adjustment on page 19 and Traction Drive Clutch Adjustment on page 21).

4. Check Axle Lock

Use the axle lock pins to lock or unlock the wheels. Lock both wheels to increase traction; unlock one wheel to allow for easier turning of the unit.

5. Check Runners

Check and adjust Runners (Runners on page 16). Allow 1/8 in. (3 mm) between scraper blade and hard, smooth surface(s). Allow 1-1/4 in. (30 mm) between scraper blade and uneven or gravel surfaces.
