Returning to the Original Track Position:
To set the track positioning of the drafting machine, loosen
the tightening nut (M), rotate the screw, and tighten the nut again
(see Figure 8 and inset).
Maintenance:
The drawing board and drafting machine should be cleaned from time to time using a damp, soft cloth. Never clean the surface with
harsh chemicals, alcohol, solvents, etc. If the drafting machine is not used for lengthy period, do not leave the vertical and horizontal
brakes in the locked position as this may cause warping of the bearings. Screws and nuts should be tightened with great care, as per
the instructions above. Lubrication or non-routine maintenance should only be carried out by qualified staff.
Alignment & Drawing of Lines:
Lock the vertical sliding block using brake (D). Draw a straight line with
a pencil resting on the supporting edge moving the vertical track to the
right (see Figure 7a).
Align drawing edge (H) with the line already drawn. Do so by loosening
knob (K) and tighten it up again once the line is drawn (see Figure 7b).
To align drawing edge (J), loosen knob (L), turn the drawing head by
90°, and tighten the knob once complete (see Figure 7b).
