3.8 TEMPORARY REAR FITTING OF THE
OPERATOR
Fit the two vibration damper bushings (C12 pos. 4) to
above and below the mounting.
Fit the operator to the mounting with the vertical pin
(C13 pos. 5), after greasing abundantly.
!
Warning
Handle the operator with care during assembly.
3.9 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:
• Remove the plug (B3 pos. 6) from the release fl ange
(B3 pos. 28) to gain access to the release valve (if
the operator is fi tted with one), storing it in a clean
place for future use.
• Withdraw the rod completely, with a slow
movement, loosening the operator manually
by turning the release valve (B3 ref. 5-5/1).
Ensure the length of the extended rod is 285
mm (C14).
• Place the template (C14 pos. 1) on the rod so that it
rests against the ledge of the fl ange (C14 pos. 2).
• Reinsert 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 (C15 pos. 3); be especially sure to
remove any traces of paint or zinc coating.
!
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 from the
vicinity and protect it from fl ying sparks.
!
Warning
To use the close delay function, it is necessary to fi x the operator with fully extended rod.
!
Warning
After having extended the rod fully, withdraw it up to the safety distance (5 mm).
Otherwise, a malfunction of the operator itself could occur.
Rest a spirit level (C16 pos. 4) on the operator body (C16 pos. 5) 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
and protecting the ball joint with a clean cloth (C17 pos. 1).
