STEEL RACK - WELD-ON FASTENINGS
!
Welding must be carried out in a workmanlike manner. Safety may
be affected if it is carried out badly.
1. Prepare all the elements of the rack that are required for the length
of the leaf (
 1 6
):
- screw 3 spacers onto each element of the rack
- position the spacers so that they touch the top of the slots,
this will allow future adjustments if the guide were to move
downwards (
 1 6
-1)
-
if an element of the rack needs to be shortened, cut it using an
angle grinder away from the slot (
 1 9
).
2. Open the leaf manually.
3. Rest an element of the rack on the pinion. Make sure that it is
level using a spirit level and fasten it to the leaf using a screw
clamp (
 1 7
).
4. Weld the first spacer to the leaf (
 1 7
-1), then move the leaf with
the rack resting on the pinion. Make sure that it is horizontal and
weld on the other spacers.
!
Protect the gearmotor from weld spatter. DO NOT connect the earth
of the welder to the gearmotor.
5. Move the leaf. Rest the next element of the rack on the pinion so
that it touches the previous element.
- Line up the teeth by resting them on an element of the rack and
assemble temporarily using screw clamps (
 1 8
).
6. Make sure that it is horizontal using a spirit level. Weld the spacers
(as in step 4). Remove the screw clamps.
7. Repeat from step 5 for all elements of the rack.
