Safety instructions for cleaning

Cleaning
To ensure problem-free machine cooling, the air ducts (ventilation grilles, channels, cooling
fins, tubes) must be free of pollution.
Explosion hazard
It is forbidden to clean the machine in an explosive atmosphere. This can result in death,
serious injury or material damage.
Surfaces can become statically charged and discharge to ignite potentially explosive
atmospheres.
8.1.4

Machines with textile fan covers

In order to guarantee an essentially unobstructed flow of cooling air containing fluff, remains
of materials or similar dirt, machines with a fan cover for textile applications have a larger air
discharge cross-section between the edge of the cover and the cooling ribs of the machine
frame.
These machines have a warning sticker on the fan cover.
8.2 Stoppages
Overview
If the machine remains out of service for an extended period of time (> 1 month), it should be
commissioned regularly (around once a month) or, at the very least, the rotor should be
turned. Please refer to the instructions in the section titled "Switching on" before
recommissioning the machine. If a rotor locking device has been fitted to the machine, you
must remove it before the rotor starts to turn.
NOTICE
Restricted motor function
If not used for longer periods of time, material damage or complete motor failure can occur.
If the motor is out of service for a period of more than 12 months, then environmental
effects can damage the motor.
Apply suitable corrosion protection, preservation, packing and drying measures.
