As a general rule, you clamp steel Wheels internally (Clamps push out against Wheel) and custom
and mag Wheels externally (Clamps push in against outside Rim edge). Check with your supervisor
if you are unclear about which method to use for a particular set of Wheels.
To clamp externally : If necessary, use the Clamps Foot Pedal to move the Clamps all the way
out
(they may be all the way out already ) , position the Wheel between the Clamps, then press
down
on the Clamps Foot Pedal to move the Clamps
in
until the Wheel is being firmly held in
place.
To clamp internally
: If necessary, use the Clamps Foot Pedal to move the Clamps all the way
in (they may be all the way in already), position the Wheel over the Clamps, then press down on
the Clamps Foot Pedal to move the Clamps out until the Wheel is being firmly held in place.
Note : The Clamps Foot Pedal works as follows: If the Clamps are in the middle of the
Turntable, pressing down and releasing the Clamps Foot Pedal moves them all the way
out. If the Clamps are all the way out, pressing down and releasing the Clamps Foot
Pedal moves them all the way back in.
• Clamp Adjustment Knobs . Move the Clamp between three different positions within the
Clamp Mechanism to accommodate Wheels of different sizes.
To move a Clamp
: Pull out and hold out the Clamp Adjustment Knob closest to the direction
you want to move the Clamp, slide the Clamp in the desired direction, release the Clamp
Adjustment Knob. If you want to move the Clamp again in the same direction, repeat the same
procedure with the other Clamp Adjustment Knob. If the Clamp is in the center position, you can
only move the Clamp one position in either direction.
