5.4 Clamping / unclamping the
wheel
The electric controller is so designed that after
turning on the mains switch the clamping jaws
remain in their instantaneous position and any
change must be effected intentionally by actuating
the pedal.
5.4.1 Clamping the wheel
CAUTION: HAND CRUSHING HAZARD. COMPLY
WITH THE MOVEMENTS INDICATED.
Note:
Before clamping the wheel make sure the contact
surfaces on wheel adaptor and rim are free from
dirt and grease.
• Move the clamping jaws to unclamped position
(Fig. 5-5).
• Slide the centring cone or centring ring (chosen
function of centre bore diameter of the wheel) on
the main shaft (Fig. 5-6).
• Bring the wheel near to the centring cone or ring.
• WITH YOUR LEFT HAND hold the wheel vertical.
• WITH YOUR RIGHT HAND, grip the plastic
sleeve of the selected clamping adapter, fit it
on the shaft and press firmly against the wheel
(Fig.5-7).
• Press the clamping sleeve and clamping means
firmly against the wheel and lift the pedal (Fig.
5-8).
• Check for proper clamping prior to the measuring run.
Notes
If the pedal is actuated once again during the clamping
process, clamping is interrupted and the clamping jaws
return to unclamped position. Clamping can also be
interrupted by operation of the STOP or the ESC key.
Spin can be started only when the wheel is clamped
and the wheel guard closed.
5.4.2 Unclamping the wheel
Note:
While the jaws unclamp, hold the wheel so that it
will not tilt when unclamped.
• Lift the pedal (Fig. 5-8).
• Remove the clamping sleeve from the chuck.
• Remove the wheel.
