5.1 OPERATOR WORK POSITION
The operator - supplied with a chain-operated manual motion
device - must be installed in the position shown in figure 4. In the
absence of the winch, the operator can be installed in any position.
If you wish to install the remote release control, first check that the
release lever does not interfere with the operator’s external parts.
The securing plate can be installed on any of the operator’s two
sides.
5.3 INSTALLING THE OPERATOR
•Release the operator with the appropriate lever.
•Fit the securing plate on the operator without tightening the screws.
•Engage the power take-off on the drive shaft.
•Position the operator (see paragraph 5.1) and rest the plate on
the support (wall or metal structure) on which you have decided
to secure it (see figure 6.).
•Tighten the screws without forcing them, while resting the plate
on the support.
•Trace the position of the installation holes.
•Remove the operator.
•Carry out the securing preparation work.
•Insert the first key securing bush and the key itself in the shaft (see
fig.2 ref. 8 and 9).
•Re-install the operator with the plate released.
•Secure the plate to the support, tighten the fastening screws on
the operator to a maximum torque of 18Nm and insert the second
key securing bush.
•Secure the two bushes after positioning them in contact with the
operator’s power take-off.
•Lock the operator.
If you wish to weld the securing plate to the support, do the wel -
ding with the operator uninstalled, and protect the drive shaft in
the power take-off engagement zone. If the operator cannot be
removed, it must be protected.
