PRESETTING OF CLAMPING JAWS

MAKE SURE ALL FOUR CLAMPING JAWS ARE
POSITIONED IDENTICALLY (FIG. 3.1-1, ITEMS 1 OR
2). OTHERWISE THE RIM MIGHT NOT BE
CLAMPED PROPERLY, COME OFF THE CHUCK
AND HURT THE OPERATOR!
Operation Manual
A Depress first pedal from the left smoothly up to
the centre position. If the pedal is released the
clamping jaws stop in the position they have reached
at the time.
B Set the clamping diameter according to the
dimensions of the rim.
Rim diameters are shown in inches on the turntable (A,
Fig. 3.1-1). The setting diameter (scale on the jaw -B-
corresponding to the scale on the turntable -A-) depends
on the position of the jaws (1 or 2, Fig. 3.1-1).

H. To reposition the jaws free the lock pin by applying
pressure on the lever (C) on the right side of each
jaw. Slide the jaws towards the required position
and release the lever: make sure the jaw is now
locked firmly. Repeat the procedure on all the
turntable jaws.
With the jaws in position 1 (1, Fig. 3.1-1), the operative
diameter is exactly as indicated by the scale (A-B)
on the turntable.
With the jaws in position 2 (2, Fig. 3.1-1), add 4" to the
value represented by the scales to obtain the
effective setting diameter.
N.B.: Turntable capacity can be changed before
pedal control.
WARNING!!
EACH JAW NEEDS TO BE SET AT THE SAME
POSITION.
