POSITIONING THE FRONT MOUNTING
Spread grease on the threaded stem of the ball joint (C16 pos. 1), fit the ball joint, along with
its nut (C16 pos. 2) and to the operator arm, screwing on to about halfway along the thread.
Insert the pin (C16 pos. 4) into the ball joint, without fitting the snap ring.
Fit the fork (C16b pos. 1) to the base of the operator with its pin (C16b pos. 2) and fix in place
with the two snap rings (C16b pos. 3).
!
Warning
• Check the strength of the mounting zone; if necessary, fit a strengthening plate of
the correct size; the strengthening plate is especially important with gate leaves
made from thin sheet steel.
• When cleaning the mounting zone for the operator front mounting, remove the
operator and protect it from flying sparks.
Rest a water level (C18 pos. 1) on the operator body (C18 pos. 2) and level the operator.
Weld the front mounting of the rod to the gate leaf with two weld-points, protecting the rod
from weld residues with a clean cloth (C19 pos. 4).
Withdraw the jointed head of the operator from the front mounting; completely remove the
operator itself from its temporary mountings, close off the flange with the correct plug; complete
the welding, covering the pin - using a clean cloth or adhesive tape (C19b pos. 5) - to protect it
from weld residue, and then clean off the residue with a wire brush (C19b pos. 6).
!
Warning
• While welding the points on the front mounting with the electrode, always cover the
rod with a clean cloth; a splinter of molten metal can cause irreparable damage to
the machined surface and make the operator unusable.
• During welding, the operator must be disconnected from the electricity supply.
After cooling, apply a coat of rustproof paint to the welded zone.
3.5 FINAL INSTALLATION OF THE OPERATOR

3.5.1 Mechanical fixing

Fix both ends of the operator to the respective mountings.
Front fixing
Spread graphitized-type grease on to the frontal anchorage pin of the ball joint.
Spread graphitized-type grease on to the ball joint.
Fit the jointed head to the pin and fix in place with the snap ring.
Rear fixing
Fix the operator to the rear mounting using the fork pin (C20 pos. 3) and the relevant lock
nut (C20 pos. 4).
With the gate leaf fully closed, re-check that the rod comes out from the operator of the
defined measure.
