5. RACK FITTING
5.1.
Release the unit and open the gate completely .
5.2.
Fit the bolts to each section of rack using the provided blocking screw. Make
sure the bolts are placed in the upper part of the holes (See Fig. 7) ;
5.3.
Lay the section of rack on the pinion of the operator as in Fig. 8 so that it
results parallel to the pavement guide of the gate and tack weld the central bolt B
to the gate (Fig. 9).
Manually slide the gate to set the bolt C close to the pinion and tack weld them;
repeat with bolt A.
5.4.
Repeat this method for all the pieces of rack that require to be fitted.
5.5.
Check all the rack pieces are perfectly alined and placed correctely
(serrations in phases). When fitting the next section of rack use a third piece as
shown in Fig. 10 to ensure a good mesh.
5.6.
Set the rack 0,06 in higher to avoid the gate weight loading on the pinion (Fig.
11).
Notice: Keep a gap of about 0,02 in between pinion cog and gear rack tooth.
5.7.
Slide the gate back and forth to check that the rack always stays in the middle
of the pinion. If required adjust the length of the spacers.
