Adjusting the air gap
View "X" on the brake.
1 Loosen the locking screws (6) by half a turn.
2 Turn the cap screws (8) into the magnetic body
(9) anti-clockwise.
3 By turning the locking screws (6) clockwise,
move the magnetic body (9) towards the
anchor plate (10) using a feeler gauge until
nominal air gap "a" is reached (see table).

check the trolley wheels
check lubrication of the driving pinion
buffers - check correct position and wear
electric motor* - check the brake lining

Service
14.1
Electric motor
For the motor it is sufficient to keep the cooling airways clean and monitor the roller bearing and its
lubrication status.
A high temperature fat must be used if the roller bearing is replaced.
CAUTION!
Brake linings and surfaces must always be clean and fat-free. Even very small amounts of dirt can reduce
the braking moment considerably.
14.2
Pneumatic motor
The pneumatic motor must be lubricated continuously by a maintenance unit.
If not otherwise agreed, the maintenance unit must be installed by the customer.
Should a maintenance unit be part of the consignment, the oiler must be filled with oil before the first start.
After longer periods of standstill, gummy oil or slight rust may lead to the fact that the motors do not start at
once or do not perform well. In most cases, this problem can be resolved by adding a few cubic meters of
cleaning oil or paraffin into the supply hose and carrying out a test run. Afterwards, fill the same quantity of
oil into the hose and repeat the procedure to ensure that the oil is well distributed. The lubrication is then
carried out by the oiler of the maintenance unit.
Recommendation:
Should longer periods of standstill be foreseen, insert some cm³ of oil into the air supply hose after the last
use of the unit and let the motor run shortly. This will prevent corrosion.
