6.4 Checking the motor brake
Due to wear on the brake linings, the braking effect of the motor
brake may decrease over time.
In this case the motor brake has to be readjusted.
WARNING!
Risk of injuries
The motor brake is a major safety element of the machine. For
this reason, the machine must in no event be operated without
any functional motor brake and only with mounted fan runner co-
ver.
•
Have the motor checked and readjusted regularly.
•
Do not continue using the machine if the motor brake is de-
fective.
1.
Switch on the motor.
2.
Once the motor has reached full speed, allow the motor to run
for a further 30 seconds.
3.
Switch off the motor and measure the time taken for the motor to
come to a complete standstill.
4.
Check that the motor comes to a complete standstill within
10 seconds of being switched off. Otherwise readjust the motor
brake!
The motor brake must bring the motor to a standstill within 10 se-
conds of it being switched off. If this time is exceeded, the motor
brake must be readjusted!
