POSITIONING THE FRONT MOUNTING
Spread grease on the threaded stem of the ball joint (C14
pos.1), fi t the ball joint, along with its nut (C14 pos.2) and
to the operator arm, screwing on to about halfway along
the thread. Insert the pin (C14 pos. 4) into the ball joint,
without fi tting the snap ring.
Fit the fork (C14b pos.1) to the base of the operator with
its pin (C14b pos.2) and fi x in place with the two snap
rings (C14b 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 fl ying sparks.
Rest a water level (C16 pos.1) on the operator body
(C16 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 (C17 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 fl ange with the correct
plug; complete the welding, covering the pin - using a
clean cloth or adhesive tape
from weld residue, and then clean off the residue with a
wire brush (C20 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 (C19).
