WORKING SURFACES
If the bare working surfaces of the machine become rusty, tarnished
or damaged, they may be readily reconditioned. Any raised burrs
should be filed off flush, and the surfaces rubbed with P200 emery
paper. Finally apply a spray-on anti-rust such as CRC 5.56 or RP7.
HINGE LUBRICATION
If the Magnabend
TM
sheetmetal folder is in constant use, then grease
or oil the hinges once per month. If the machine is used less, then it
may be lubricated less frequently.
Lubrication holes are provided in the two lugs of the main hinge
plate, and the spherical bearing surface of the sector block should
also have lubricant applied to it.
ADJUSTERS
The adjusters at the ends of the main clampbar are to control the al-
lowance for the thickness of the workpiece between the bending -edge
and the bending beam. The adjusters are factory-set to give a thick-
ness allowance of 1 mm when the adjusters indicate "1". To reset
this, proceed as follows:
1. Hold the bending beam at 90.
2. Insert a small piece of 1 mm sheetmetal at each end between the
bending-edge and the bending beam.
3. Ignoring the indicating marks, adjust the adjusters until the 1 mm
pieces are just lightly "nipped" between the bending -edge and the
bending beam.
4. Using a 3 mm Allen key, carefully loosen the grub -screw to free
the knurled ring of one of the adjusters. Then rotate the ring till
the indicating slit indicates "1". Do this without rotating the inner
body of the adjuster. Then re-tighten the grub-screw.
5. Reset the other adjuster in the same manner.
The spring-loaded lifting balls in the underside of the adjusters may
stick if dirt or rust-forming moisture gets in. If this happens, remedy
it by pressing the ball in and out with a blunt tool while spraying in a
penetrating lubricant such as CRC 5.56 or RP7.
