• Proceed by fi xing the other components of the rack as
shown (Fig.21).
!
Warning
Always check with a template (Fig.22 A) that the pitch
between the bar linkages is kept even.
If the fi t is imperfect and it is impossible to maintain the
correct pitch, then you need to adjust them.
• Proceed as given in the previous points.
3.3.2 Galvanized steel rack
Fitting:
Fixing is made using the threaded bolts welded on the gate
mount. It is recommended to weld the bolts along their entire
circumference.
!
Warning
DO NOT weld the rack sections directly on the gate panel
and DO NOT weld adjacent parts one to the other or the
free space between them (any following adjustments would
be impossible).
Keep the negative lead of the welder CLEAR OF the gear
motor.
NEVER WELD WHEN THE GEARED-MOTOR IS
CONNECTED TO THE MAINS.
ALWAYS PROTECT THE WELDINGS WITH A ZINC-BASED
RUST-PREVENTER SPRAY.
• Throw the gate open.
• Fix the spacers to the steering rack with screws and
washers (Fig.23) making sure to drive them right in the
middle of the slot.
• Position the initial section of the steering rack on to the
pinion of the gear motor, move the spacers in contact with
the gate and align the fi rst slot with the vertical axis of the
pinion, then fi x the spacer to the gate with a welding spot
(Fig.24).
• Unlock the gear motor (see paragraph) and move the gate by
hand until the second spacer is aligned with the vertical axis
of the pinion, then fi x the spacer to the gate with a second
welding spot (Fig.25).
• Move the gate beyond the fi rst section of the steering
rack.
• Fit a 20 cm-long section (Fig.26) to the steering rack. Near
the second section of rack to the fi rst one by bringing it in
contact with the piece used as ruler. Poition the fi nal part
of the second rack section onto the gear motor pinion by
moving the gate by hand.
• Position the spacers of the second rack section onto the
gate and fi x them with two welding spots.
• Repeat the steps above with all elements of the steering
rack you necessitate, then weld in position all spacers on
the gate: weld them along their entire circumference.
