•
First, the milling spindle must be swivelled fully forwards via
the control (po45.5°)

It must now be possible to move the V-belt pulley by hand. By turning it, you can now check whether
the brake is dragging, which means that it has been adjusted too excessively.

•
Now turn the brake release switch back to “
Normal Operation
”.
•
Start the spindle motor and wait until the machine has reached full speed.
•
Then switch off the machine and check the braking time to standstill.

If the braking time is still over 10 seconds, repeat the adjustment procedure (see section
and check the adjustment again.
•
If the adjustment was not successful, please contact the customer service of the manufacturer.
If rattling noises occur in the area of the fan blade when turning the motor, please contact cus-
tomer service. Possibly the brake lining is worn out.
