General maintenance instructions
The basic requirement for a safe operation of the machine/system is its regular
maintenance. The work set out in the inspection lists must be carried out and the
indicated maintenance intervals must be kept. Maintenance also includes a
regular cleaning according to the operating conditions.
Maintenance work must be carried out by skilled personnel only.
How to maintain motors
Motors have to be maintained according to the manufacturer's instructions. The
documents are included in the annex to these operating instructions.
How to maintain gear units
Gear units have to be maintained according to the manufacturer's instructions.
The documents are included in the annex to these operating instructions.
How to order spare parts
The spare parts list and spare parts drawings are included in a separate chapter
at the end of the operating instructions. The spare parts list includes the data of
the order so as to ensure a correct attribution of the spare parts.
In case of inquiries or orders, please send a copy of the spare parts list including
information on the spare parts required to our spare parts department. You will
find the address in the introduction at the beginning of the operating instructions.
Chain drive
In order to achieve an efficient power transmission and the usual service life of
the chain, the correct chain tension and the indicated lubrication intervals must
be kept. The elongation of new chain drives is especially strong at the beginning
of their operating time. Therefore, the chain tension is to be checked more often
within this time. When the chain is taken up, the chain sag must be about 1 to 2
% of the centre distance. An excessive tension of the chain drive reduces the
service life of the drive components.
The sprocket wheels must be aligned and the shafts must remain parallel when
the chain drive is taken up.
Warning!
Risk of crushing between sprocket wheel and chain!
Work must be carried out only by skilled personnel when the machine is discon-
nected! Re-mount all safety covers after having completed the work!
