3.1 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!
A Depress fi rst 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).
Fig. 3.1-1
C 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
fi rmly. 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.
