The scratch guard may be installed on the clamping cup to protect aluminum rims from being marred, but should not be used on steel
wheels.
FRONT CONE MOUNTING PROCEDURE
This procedure utilized a tapered cone inserted from the front side of the wheel instead of the backside as previously described.
Select the proper wheel-mounting cone by placing it in the center bore of the wheel to be balanced. Choose the cone that contacts
the wheel nearest the center of the cone.
Mount the wheel with the inner rim facing the balancer. Place the wheel-mounting cone on the spindle with the small end of the cone
facing the front of the wheel.
Install the wing nut and pressure ring assembly onto the spindle shaft against the wheel and secure the entire assembly by firmly
tightening the wing nut.
Heavy wheel centering may benefit by pulling the tire away from the hub face at top dead center while tightening the wing nut. This
helps the wheel to overcome gravity against the hub or spacer.
PRESSURE RING
The pressure ring should be used to prevent the wing nut from directly contacting an adaptor or a cone.
It may also be used in place of a pressure cup if space is limited between the wheel and the end of the spindle.
