5.4 WINCH ADJUSTMENT
Unwind the supplied chain completely and join one of it its ends
to the one already fitted to the winch, without cutting the service
clip. Use one of the supplied links, selecting from those in steel (see
figure 7 ref. A) or from those in plastic (see figure 7 ref.B).
The plastic links must be assembled. Tighten the steel links accura -
tely, to allow the chain to move perfectly, inside the winch.
Cut the chain to size, without allowing the lower part of the ring
it forms from touching the floor, and making sure that it is wound
around itself (see figure 8).
Assemble the other side of the chain, in the same way as in figure 7.
Cut the service clip only when the chain is installed.
Adjust the screw of the balancing spring (see figure 9) so that the
winch support disappears completely inside the plastic enclosure
(see figure 10).
Check if the traction of just one of the chain sections causes the
winch to engage and, if the winch returns to its idle position when
it is released.
Tighten the securing nut and make sure that operator activation
is not inhibited or interrupted by the tripping of the winch safety
microswitch.
We advise you to provide an anchoring point for the lower part of
the chain so that it cannot hinder the transit of people or of ope -
rating means. Apply the sticker indicating the opening and closing
directions, in a clearly visible way.
If you are using the chain extension kit, replace the balancing
spring (fig. 9 ref. 3) with the one contained in the kit. If you are
using plastic joints, we advise you to glue them together during
assembly (see fig. 7 ref. B).
