R
3.6 TEMPORARY REAR FITTING OF THE
OPERATOR
Fit the two vibration damper bushings (C13 pos. 4) to above and
below the mounting.
Fit the operator to the mounting with the vertical pin (C14 pos. 5),
after greasing abundantly.
!
Warning
Handle the operator with care during assembly.
3.7

FRONTAL POSITIONING OF THE OPERATOR

If it has been decided to use the maximum useful length of the
rod (distance A+B = useful piston stroke length) then the supplied
template needs to be used, in the following way:
• Fit the key (C15 pos. 1) to the release screw and turn in an
anti-clockwise direction to release the operator manually.
• Fully extend the rod slowly.
Ensure the length of the extended rod is 285 mm
(C18).
• Withdraw the rod of 5 cm.
• Protect the rod (C16 pos. 2).
• Withdraw the rod up to the edge of the template, and check that
there is about 5 mm clearance between the rod washer and
the operator plug.
• Clean the welding zone for the front mounting perfectly with a
suitable tool (C17 pos. 4); be especially sure to remove any traces
of paint or zinc coating.
!
Warning
To use the close delay function, it is necessary to fi x the operator
with fully extended rod.
After having extended the rod fully, withdraw it up to the safety
distance (5 mm). Otherwise, a malfunction of the operator
itself could occur.
• Check the strength of the mounting zone; if necessary, fi t
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 from the vicinity and protect
it from fl ying sparks.
Rest a spirit 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 the weld residue with the template
used for the positioning (C19 pos. 3) and protecting the ball joint
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 fl ange with the correct plug; complete the welding,
covering the pin (C20 pos. 5) (using a clean cloth or adhesive tape)
to protect it from weld residue, and then clean off the residue with
a wire brush (C20 pos. 6).
!
Warning
• Whilst 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 render the operator unusable.
• During welding, the operator must be disconnected from
the electricity supply.
