- Check work area door (optionally with electr. drive) and viewing glass
Orientation
Inspection and maintenance of the work area door includes several steps:
- Inspection of the viewing glass for damage.
- Checking the safety label on the viewing glass (replacement interval 8 years).
- Checking/adjusting or replacing, if necessary, the wipers.
- Checking the work area door for smooth opening/closing.
- Check functions of the automatic work area door (optional - electric door drive -
Follow manufacturer's documentation from Langer & Laumann ).
The viewing glass consists of three panes. the inner pane of tempered glass, the
central pane of polycarbonate, and the outer pane also made of polycarbonate. The
inner pane is relatively resistant. It can be cleaned with any commercially available
cleaning agents. Only the center pane is essential for the impact resistance of the
viewing glass.
The polycarbonate panes are subject to natural aging and therefore must be
subjected to regular visual inspection. Through contact with cooling lubricant, the
aging process is accelerated even further.
If the viewing glass is damaged, it must be replaced. This is
necessary regardless of the extent of damage. Even with minimal
damage, the impact resistance of the glass can no longer be
guaranteed.
Heavily soiled or damaged wipers may cause damage to the inner pane. Moreover,
it may be possible that the work area door can be moved only with considerable
effort due to heavy soling or chip deposits in the wipers.
Regularly check and clean the guide rails of the work area door.
Check function of the automatic work area door with electric drive (option like open/
close) with different speeds with or without obstacle detection check.
Requirement
The automatic work area door can be tested only when the machine
is switched on and fully functional.
Be sure that the wipers have been checked before testing the
automatic work area door. Be sure to remove any chip nests and
make sure that the wipers have been cleaned and attached to the
plates.
