NOTES FOR THE INSTALLER

7.0     Maintenance

Information

Periodically check the proper functioning of the operator. Do 
this check at least every 12 months

Warning

!

Maintenance must be performed only by skilled technicians.

Warning

!

Before doing any maintenance job, turn the operator off by 
means of the differential switch of the electric system.

•    Grease the joints with graphitized grease every year. 
•    Check the general condition of the gate structure. 
•   Check the mechanical resistance of hinges, operator mountings 

and stops. 

•    Ensure the installed safety devices are in working order (photocells, 

rubber barriers,…) and adjust the thrust force at the end of the 
gate leaf (max. 147 N).

•   Ensure the electrical system and the differential switch are 

effi cient.

•    Check the setting of the pressure relief valve. 
•    Check the tightening of the safety lock. 
•   Depending on the use of the operator, check the oil level of 

the system.
