Maintenance T 3000-3500
The maintenance intervals must be decided individually as they are dependent
on the application and the frequency of use. We recommend maintenance at
least once every six months.
1. Check the balancing springs. In case of a faulty spring, all springs must be
replaced simultaneously.
2. Check that the boom is perfectly balanced by the springs (see page 25).
3. Check barrier housing and boom for accidents and damage and replace
where necessary.
4. Ensure that the potential earthing cable is still connected to the housing
and to the door.
5. Check that the operating instructions are complete.
6. Check that all safety equipment works properly (induction loops,
photoelectric barriers, power reversal,...).
7. Check that the barrier is still secure on the foundation.
8. Perform a visual inspection and tighten screws where necessary.
9. Grease the guide bars using multi-purpose grease (temperature range -
30°C to +70° C). Remove excess grease.
