Professional repair of a defect drive can only be performed at the
manufacturer’s factory or manufacturer-certifi ed specialist company.
Unauthorized opening or manipulation of the drive terminates warranty.
1. Exchange defect drives or have them repaired by the manufacturer.
2. In case of problems during installation or normal operation the

To ensure continuous function and safety of the drive periodic maintenan-
ce by a specialist company is required at least once a year (as mandated
by law and recommended by manufacturer). Operational readiness must
be checked regularly. Frequent inspection of the system for imbalance
and signs of wear or damages of cables and fastening elements must be
performed.
During maintenance contaminations must be removed from the drive.
Fastenings and clamping screws must be checked for tightness. Test runs
during the opening and closing procedure of the devices must be per-
formed.
The drive itself is maintenance-free. Defect devices may only be repaired
in our factory. Only spare parts of the manufacturer may be used. When
the connection cable of this device is damaged it must be replaced by the
manufacturer or his customer service or a similarly qualifi ed person to
avoid endangerment.
It is recommended to conclude a maintenance contract. A sample main-
tenance contract can be downloaded from the homepage of
Firm a
UMÜlleR
a
UMatIc
GmbH
(

).
While cleaning the windows, drives may not have direct contact with
water or cleaning agents. Drives must be protected from dirt and dust
during the construction phase or renovations.
Maintenance process
1.
Open or extend power-operated casement completely.
2. Completely disconnect the system from the mains and secure it
against automatic or manual activation.
3. Check windows and fi ttings for damages.
4. Check all mechanical fastenings (if required, observe information on
torques in installation instructions).
5. Check electric drives for damages and contaminations.
6. Check connecting cables (drive cable) for:
- tightness of the cable screw
- functionality of the strain relief
- damages
7. Check the mobility of hinges and fi ttings and re-adjust or apply
lubricant, e.g. silicone spray (observe the instructions of the manu-
facturer of this window system).
8. Check peripheral seal, remove contaminations or replace.
9.
Perform cleaning to maintain functionality (e.g. clean extending
elements of the drive, such as chains or spindles by damp wiping them
with acid or lye-free agents and drying them and, if required, lubricate
them with cleansing oil e.g., Ballistol).
10. Turn on operating voltage.
11.
Open and close the power-operated window via the operating
voltage (functional test).
12. If available, check and re-adjust protection systems of the safe guard
fi xture.
13. Check the intactness of the CE label at the power-operated system.
14.
Check the intactness of warning instructions and labels at the
respective drive.
15. Perform a risk assessment in accordance with Machinery Directive
2006 / 42 / EG, if required, e.g. after modifying the machine.
