8.1 Maintenance

Motors
Excessive dirt, chips or dust can negatively influence the motor functions. In ex-
treme cases lead to motor loss. Clean the cooling fins of the motors at regular
intervals (after one year at the latest) to reach a sufficiently high heat emission
surface. If the cooling fins are partially covered with dirt, sufficient heat dissipa-
tion via the ambient air is no longer ensured.
Insufficient heat dissipation can have undesirable consequences:
Danger! Electric voltage! Operations in the vi-
cinity of live parts are extremely dangerous.
Personal and material damage during mainte-
nance work in operation!
Hot surfaces with temperatures over 70 °C may
cause burns!
