Note
Each time before you readjust the brake linkage (2a, 2b), the thickness of the lining on the
brake shoes must be checked. The thickness of the lining must still be at least 2 mm.
1. Disconnect the brake linkage (2b) from the brake lever (4).
2. Loosen the counter nuts (1) on the brake linkage (2a).
3. Turn the brake linkage (2a) until the brake lever path a1 is about 30 mm on activation.
Note
The compensation lever (11) must be flush both in the oblong hole (I), and in the upper part (II)
of the support (12) for the following settings.
4. Disconnect the brake linkage (2a) from the brake lever (5).
5. Then mount the brake linkage (2b) on the brake lever (4) again (note the length of the brake
lever (RL)).
6. Loosen the counter nuts (3) on the brake linkage (2b)
7. Turn the brake linkage (2b) until the brake lever path a2 is about 30 mm on activation.
8. Then mount the brake linkage (2a) on the brake lever (5) again (note the length of the brake
lever (RL)).
9. Activate the brake. When you do this, the cylinder stroke X must be between 25 mm and 50
mm.
Note
If the cylinder stroke X is too great, readjust the brake linkage (2a and 2b) (increase the length
of the brake linkage).
After the brake linkage (2a, 2b) has been readjusted, check whether
• the wheels turn freely when the brake is released. If they do not, the brake linkage
(2a, 2b) must be readjusted (shorten the brake linkage),
• until the threading overhang (6) of the brake linkage (2a, 2b) on the clevises is
min.=0 mm.
If the minimum threading length (6) (min. = 0 mm) cannot be reached, the brake
lever (4, 5) should be moved on the brake shafts against the operating direction (7).
10. Tighten counter nuts (1, 3) on the brake linkages (2a, 2b).
Note
Make certain that all safety equipment is mounted.
