ANNUAL CHECK

BGR 232 directive "Windows, doors and main doors with mechanical
operation" is applied. It can be obtained from the National Insurance
Institute for Industrial Accidents of your trade association or from us
on request.
Maintenance interventions on windows, doors and main doors
with mechanical operation must be performed only by personnel
authorised by the company, having the necessary experience and
skills (BGR 232).
NOTE: all the technical characteristics indicated refer to a temperature falling between ­5°C and +40°C. • Nice reserves the right to
change all the modifications to the product it deems necessary at any time, but keeping the functions and intended use unaltered.
We recommend using 20 rpm gearmotors for doors with vertical movement with conical cable winder drum.
For non-balanced sectional doors we recommend using RDF series gearmotors with parachute device.
When assembling gearmotors with 31.75 mm diameter shaft from the left, the tab is to be blocked only with a shoulder collar
because fixing with a screw could break the shaft.
Only suspended assembly is allowed for "light chain" gearmotors (fig. 4).

Information for whoever carries out the checks
Gearmotor:
The mechanism is maintenance­free and it is provided with
permanent lubrication. Absolutely no rust must form on the output
shaft.
Fixings:
Make sure that the fixing screws are all in the correct position and
in perfect condition.
Balancing by weights (e.g. in the sectional main doors):
The door must be balanced in all the positions (see the door
assembly instructions) when balancing is done with weights
according to the procedures prescribed by the standards.
Brake (if present):
During the annual check perfect brake operation is to be ascertained.
In the case of heavy wear of the brake pads, it is necessary to
replace the complete brake. Before replacement, disconnect the
cables connected to the electric card.
