Standard Front Cone Mounting
A wheel should be centered by the outer side of the
hub only when the inner surface will not provide an
accurate surface to center on.
Figure 8 - Front Cone Mounting
1. Select the cone that best fits the center hole in
the wheel.
2. Lift the wheel onto the shaft and slide it back
against the shaft faceplate.
3. Slide the cone onto the shaft and into the center of
the wheel. You will need to lift the tire to seat the cone
in the center hole.
4. Install the hub nut (without pressure cup) onto the
shaft. Tighten it securely against the cone. The hub nut
must engage the threads for at least four full turns.
Note: If the hub nut will not tighten completely
because of a lack of threads, use an additional cone as
a spacer between the mounting cone and the hub nut.
The wheel must be forced firmly against the faceplate.
Alternate Mounting
If the wheel has a protruding outer hub which will not
permit the use of the pressure cup, or the cup will not
permit the hub nut to engage at least four turns of the
shaft, this alternate method should be used.
1. Select the cone that best fits the center hole in the
wheel. Slide the cone onto the shaft with the large end
towards the faceplate.
2. Lift the wheel onto the shaft and center it on the
cone.
3. Use the small nylon spacer (no-mar ring) or a
centering cone to press against the outer wheel hub.
4. Install the hub nut (without the pressure cup) onto
the shaft. Tighten securely.

Pneumatic Shaft (PL Version Only)
Use the most appropriate mounting method for the
wheel, but instead of using a hubnut use the pneumatic
sleeve. When the pneumatic sleeve is in place, press
down on the positioning pedal to mount the wheel on
the shaft.

Important: Always be sure to remove the wheel
assembly from the pneumatic shaft before disconnect-
ing the air supply from the machine.
