STEEL RACK  WELDON FASTENINGS
i
Rack thickness: 8 mm for leaves weighing up to 400
kg max, 12 mm for leaves weighing more than 400 kg.
1. Screw 3 spacers onto each element of the rack,
positioned so that they touch the top of the slots.
Open the leaf manually.
2. Rest an element on the pinion. Check that it is hori-
zontal and secure it to the leaf using a screw clamp.
3. Weld the first spacer to the leaf and then move the
leaf with the rack resting on the pinion. Make sure
that it is horizontal and weld on the other spacers.
i
Protect the gearmotor from weld spatter. DO NOT con-
nect the earth of the welder to the gearmotor.
4. Move the leaf. Connect the next element (use
screw clamps and a support). Rest it on the pinion,
make sure that it is horizontal, and weld the spa-
cers. Remove the clamps and repeat the procedure
to complete the rack.
i
If an element of the rack has to be shortened, cut it with
an angle grinder so that you leave two fastening points.
