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).
