Information for whoever carries out the checks
Gearmotor:
The mechanism is maintenance free 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.
TECHNICAL SPECIFICATIONS
NOTE: all the technical characteristics indicated refer to a temperature falling between -5°C and
+40°C. •
DAS 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.
