The gas strut is assembled and set up to operate at a pre-determined force value and should
not be adjusted. If the force is too strong, then a small amount of gas may be released from

spring requiring recharging by the manufacturer.
11.4 Powered Gate
Note:
The power closer used on the gate is the same as that used on powered fire doors. Refer to
the notes in section 11.2 before assembling the gate linkage.
2) With the gate installed in the frame, drill the corner upright to suit the gate frame
dimension as shown below. Fit the linkage to the corner upright using the nutserts and
fixings provided.
3) Ensure the plastic filler piece for the cover is in place then fit the spigot to the closer.
Note: Do not tighten the spigot fully at this stage. It should be just clear of the splines
and free to rotate.
4) Secure the linkage to the spigot using the M6 x 20 countersunk screws
5) Now ensure the spigot engages fully with the splines in the closer and tighten the
centre bolt, using a hexagonal key through the access hole in the linkage arm; it may
be necessary to swing the gate open until it coincides with the next position
6) Apply just enough opening pressure on the door (against spring tension) to reduce the
load on the locking screw and remove the screw. The screw should be stored in the
