8 Maintenance
8.1 Safety instructions
Warning! Risk of injury: Improper adjustment and setup work can lead to serious bodily injury or mate-
rial damage. For this reason this work may only be carried out by authorised, trained personnel who are
familiar with the operation of the machine and in strict observance of all safety instructions.
• Before beginning any maintenance work on the ma-
chine, switch it off and secure it against accidentally
being switched on again.
• Before commencing any work with the machine, in-
spect it to ensure that it is complete and in technically
good condition.
• Ensure that there is sufficient space to work around
the machine.
• Keep the work area orderly and clean. Components
and tools that are not put in their correct place or put
away may be the cause of accidents!
• Install the safety equipment according to the instruc-
tions and check that it functions properly.
Warning! Danger – electric current: Work on electrical fittings may only be carried out by qualified person-
nel and in strict observance of the safety instructions.
8.2 Drive belts
Check periodically that all screws are tight and also
check the condition of the protective equipment.
Following the first few operating hours, the belt tension
has to be controlled, as the belt will extend. To check the
tension, press inwards onto the belt in the middle with a
weight of 3-4 kg.
The belt deflection should not be more than 5-6 mm. To
readjust the belt, open the screws and readjust the ten-
sion with the screw.
It is important to always maintain the correct belt tension,
as belts which are too loose will weaken the drive power
and the brake power and belts which are overtightened
will lead to overheating.
