Do not
use the snowthrower on a roof.
•
Do not touch the engine while it is running or soon
after it is stopped because the engine will be hot
enough to cause a burn. Do not add oil or check the
oil level in the crankcase when the engine is running.

Perform only those maintenance instructions described
in this manual. Before performing any maintenance,
service, or adjustment, stop the engine, remove the key

bracket (Fig. 4).
9.
Check the adjustment (refer to steps 2 and 3 above).
After extended use, the drive belt may wear and lose its
proper belt tension. Improper belt tension causes belt
slippage and decreases the performance under a heavy
load. Belt slippage may occur after two or three seasons of
normal usage (10 to 15 hours). If the drive belt slips
(continuously squeals) under a heavy load, increase the
belt tension by repositioning the spring end in the bottom
hole of the control bar bracket (Fig. 4).
Using the incorrect adjusting hole in the control bar
bracket can reduce the drive belt life. Occasional belt
slippage (squealing) may occur in extremely wet
conditions due to moisture in the drive system. T
