- Check the work area door and window pane
Orientation
Inspection and maintenance of the work area door includes several steps:
- Inspection of the window pane for damage.
- Checking the safety label on the window pane (replacement interval 8 years).
- Checking/adjusting or replacing, if necessary, the wipers.
- Check the work area door for smooth opening/closing.
- Automatic work area door (optional). Hydraulic valves and motor, control panel,
rack and spur gear. (for hydraulic door drive)
- Automatic work area door (optional – electric door drive – follow the
manufacturer’s documentation).
The window pane consists of three panes. The inner pane made of tempered glass,
the central pane made 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 window pane.
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 window pane is damaged, it must be replaced. This is
necessary regardless of the extent of damage. Even with minimal
damage, the impact resistance of the pane 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 soiling or chip deposits in the wipers.
Check the guide rails of the work area door. The guide bars must be checked and
cleaned regularly so that the work area door can be moved without much effort.
Procedure
1. Check window pane for damage.
2.
Clean the outer pane with a soft cloth or sponge and glass
cleaner or soap and water. Do not use abrasive or alkaline
cleaners (e.g., benzene, acetone or carbon tetrachloride) and no
sharp tools or sharp objects (such as razor blades or
screwdrivers).
Clean outer pane.
3. Clean inner pane.
4. Check wipers. Remove and clean the wipers. If the wipers are severely
deformed or damaged, they must be replaced. To clean the door panels evenly,
be sure to reinstall the wipers after their removal aligned in parallel and ensure
that they snugly contact the work area door.
