Maintenance 

The 750 Operator 

 
The FAAC recommended maintenance schedule varies 
according to the frequency of use of the operators, 
whether lightly used operators (once or twice an hour) 
or heavily used operators (many cycles per hour). 
 
 

Check the oil. 

To check the oil level correctly, remove the oil filler cap 
on the top of the power unit. A dip stick is attached to 
the bottom of the cap for checking the oil level as 
shown in Figure 24. 
 
 

Light duty use: check once per year 

 

Heavy duty use: check every 6 mo 

 
 
Change the oil. 

Changing the oil completely in the hydraulic system of 
the 750 Operator requires removing the power unit and 
drive unit from their installed positions unless you are 
able to pump the oil out of both units.  
 
 

Light duty use: change every 4 yr 

 

Heavy duty use: change every 2 yr 

 

 

Figure 24. When you check the oil, make 
sure the oil level falls between the 
minimum and maximum marks on the oil 
dip stick 

 

 
Check the pressure settings. 

 

Light duty use: check once per year 

 

Heavy duty use: check every 6 mo 

 

Check all reversing devices. 

Every six months, you should verify that all installed 
reversing devices work properly.  

The Control Panel 

The control panel requires no maintenance. 

 

 
 

Troubleshooting 

 WARNING! 

Before you do any work on the control panel, be sure to turn off the main power. 

Problem: The gate does not respond to an activating 
signal. 
 
Solution: 

Verify that you have correctly wired the operator to the 
control panel. 
 
Verify that the LED DL3 is on. If it is not illuminated, 
then check the fuses on your control panel. 
 
If the LED DL3 is not illuminated and your fuses are 
okay, then the stopping device is being triggered and is 

preventing the gate from responding to your signal. If 
you have no stopping device installed, then be sure you 
have installed a jumper across the appropriate terminals. 
 
Verify that your activating device works properly. Either 
DL1 or DL2 (depending on your gate design) should 
illuminate when you signal the gate to close (or open) 
and LED DL3 should be on. If  either DL1 or DL2 does 
not illuminate when you signal the gate, then the 
problem may be in your activating device. Short across 
the appropriate terminals. If the short causes the gate to
