Opening aid - Electric actuator LA36:

Chapter 04: Assembling the opening aids

The LA36 electric actuator is equipped with internal limit switches that switch off 

the actuator in the stop positions. Accordingly, there are no special 

requirements for limit switch polling even on the control side.

1. First, the e-controller (available from Hailo as an option) should be fitted into 

the space provided, and the wiring to the cover put in place.

2. Next, the mounting bracket with the pre-mounted nuts and washers is 

screwed to the frame on the hinge side.

The bracket must be self-supporting to the back against the concrete!

3. The actuator is attached to the frame bracket with the motor side (as shown 

in the images below) at the bottom, using the screw, nut and anti-removal bolt.

Tighten the nut only to the point where the anti-removal bolt does not stick 

against the frame bracket!

4. Next, use the e-controller to extend the actuator fully until it reaches the stop 

position, so that the piston rod can be installed at the attachment point of the lid 

(using the screw, nut and spacer tubes).

Only tighten the nut to a point where the screw can still be rotated!

Note: Covers equipped with an LA36 actuator may have additional gas-

pressurised springs, depending on the size. These are needed for even opening 

and as protection against overloading the actuator in the event of heavy lid 

weights.

The gas-pressurised springs are installed as described on page 5.
