Troubleshooting Information
KMR 1250 B, LPG, D
Adjust parking brake
Note:
With the parking brake released, there must
be NO braking effect, and the wire and cas-
ing cable (1) must be fully relaxed.
The parking brake is required to securely hold
the unit in place when applied on a grade of 25%,
and with the unit loaded to capacity.
At the same time, tension (X) of the pull spring (7)
may not extend by more than 5 to 10 mm (0.20-
0.40 in).
Brake adjustment is accomplished with adjust-
ing nut (5).
-
Starting with serial no. 10600, a pull
spring is installed on the operating lever
(9). This ensures a more easy movement
of the brake when the operating lever (9)
is actuated.
