J. Initial operation and maintenance
Initial operation
Attention!
Power operated windows, doors and gates for industrial use have
to be checked before initial operation or if necessary, but at least
once a year by a specialist (with written documentation)!
Maintenance instructions
Please observe the following points in order to guarantee a faultless function:
• Check the separate counterbalance of the door regularly.
The door has to be moved easily by hand if the operator is disengaged.
• The door system, especially cables, springs and fixing components have to be
checked regularly for signs of wear, damages or for faulty balance.
• The function of automatic cut-out 'open' and 'close' has to be checked
regularly.
• Test monthly, if the operator reverses when the door meets an obstacle of
50 mm that is lying on the floor.
Correct, if necessary, the adjustment of the reversion function and test it
again, because a wrong adjustment could be dangerous.
Caution!
The door system must not be used during repair or adjustment
works. A fault in the system or a wrongly balanced door may
cause injuries.
