CHECKING TIRE PRESSURE

The air pressure in each tire (Figure 8) should be 20 psi (136 kPa) and should be equal for both tires for best per- formance. Be sure to keep caps on valves to prevent entry of debris into the valve stem when tires are filled.

AUGER GEAR CASE LUBRICATION

1.Place the snowthrower on a level surface.

2.Remove the pipe plug (A, Figure 9).

3.Check the lubricant level. It should be level with the lower edge of the plug opening. If not, add Simplicity Winter Weight Worm Gear Oil (available from your dealer).

4. Re-install pipe plug, and tighten securely.
