- Check work area door 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.
- 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 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.
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 viewing glass 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 be able 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.
