Cleaning the motor
Explosion hazard due to overheating of the machine caused by a layer of dust
Deposits of dust have a thermally insulating effect, causing the machine to overheat. The
maximum surface temperature of the machine is not adhered to. The dust is ignited as a result,
causing an explosion. Death, serious injury and material damage will result.
• Regularly remove dust from the machine.
• Do not allow dust layers thicker than 5 mm to build up.
• Only switch the machine on when the dust has been removed.
NOTICE
Dust deposits cause higher housing temperatures
Dust deposits prevent heat from being radiated.
Keep the drive free from dirt and dust.
NOTICE
Cleaning with a high-pressure cleaning appliance
Water penetrates the geared motor. Seals are damaged.
Do not use a high-pressure cleaning appliance to clean the geared motor.
Do not use tools with sharp edges.
De-energize the drive unit when cleaning the drive unit.
