NOTE: DO NOT ALTER SPEED ADJUSTMENT SCREW BEFORE COMPLETING INSTALLATION
Step 1 - Fix gatepost bracket to the gatepost using a temporary clamp and using the
dimensions shown on page 2.
Step 2 - Using one of the hexagon headed securing pins, place one end of the fitting bar to
the gatepost bracket hole farthest away from the gatepost. Fix the gate bracket to the fitting
bar using the other hexagon headed securing pin, and then swing the bar and the bracket
around to the gate, ensuring that the brackets are horizontally in-line with each other. Fix to
gate using a temporary clamp. Remove the fitting bar.
Step 3 - Open the gate to 90 degrees and make sure the distance between the centres of the
gatepost bracket hole and gate bracket hole are 22 in. or more. If you have an in-line hinge
arrangement check that the two holes closest to the gate post have a distance 22 in. or more
between hole centers. If you have an offset hinge arrangement check that the two holes
farthest from the gate post have a distance of 22 in. or more between hole centers.
Step 4 – After confirming the gate-opening angle is sufficient; mark the fixing holes for the
two mounting brackets on the gatepost and gate. Drill and tap the fixing holes in the
gatepost and gate, and fix the mounting brackets to the gatepost and gate. Alternatively,
weld brackets to gatepost and gate.
Step 5 - Grease the nylon spacers and hexagon headed securing pins. Open the gate until
the holes on the mounting brackets align with the holes in the gate closer cylinder. Then fit
the gate closer cylinder and spacers to the mounting brackets on the gatepost and gate using
the hexagon headed stainless steel securing pins making sure the speed adjustment screw is
facing away from the gate.
Step 6 - Turn the speed adjustment screw on the closer counter-clockwise and the gate will
begin to close automatically.
Step 7 – Test that the gate opens and closes correctly and that the hand force needed to
open the gate is appropriate. If the hand force is too much, open the gate a little, turn the
closing speed adjustment screw fully clockwise to hold the closer slightly compressed, remove
the hexagon headed securing pin from the gatepost bracket and move the closer one hole
nearer to the gatepost. Refit the hexagon headed securing pin. Repeat steps 6 and 7 until
gate operates correctly, and finally, adjust the closing speed.
Step 8 - Fit a mechanical stop to restrict the gate’s opening angle. To do this, open the gate
to a position where the distance between centers of the hexagon headed fixing pins is 22 in.
or more. Set the gate’s mechanical stop to restrict the opening at this point.
Step 9 - Check all bracket fixings are secure. Fit M6 socket button head screws and washers
into the underside of the hexagon headed stainless steel securing pins using a thread locking
liquid.
Step 10 - If the brackets have been welded, paint brackets and gate parts as necessary.
Finally, coat the eyelets, exposed parts of the stainless steel fixing pins and socket button
screws with a layer of grease. The gate closer is now ready for use.
Step 11 – Review the maintenance instructions on the following page and ensure that regular
maintenance is completed on the gate closer.
