Stop Adjustment

CC7847-UN-25SEP98
Right Side - Narrow Adjustment; Left Side - Wide
Adjustment
A - Stop
B - Sheave Side
C - Shim
D - Shim
IMPORTANT: Sheave with larger diameter hole must be next to
spring and away from shims.
If stop (A) bounces while falling into place between sheave
sides (B), the area is too WIDE. Remove shims (C) as required.
If stop does not fall all the way in between sheaves, the area
is too NARROW. Add shim (D) as needed.

Check Stop Adjustment

CC7848-UN-05OCT98
A - Stop
B - Sheave Side
C - Shim
If blade of stop (A) drops between sheave sides (B) snugly without
bouncing, the number of shims (C) is correct.
