Air Cushioned Dead Head Assembly
Refer to Figures 10 and 11. The air-cushioned dead
head is for use on very small radius grinding. When
connected to a source of shop air (80-90 psi), the
belt rides on a cushion of air to decrease head and
belt wear. The dead head is easy to use, and adapts
to any of the available radius tips.

Assembly of Pedestal
Unpacking
The grinding machine pedestal is shipped separately
from the grinding machine. Transport the shipping
containers to the installation site before unpacking.
Unpack the pedestal and grinding machine. Locate and
open the plastic bag containing four 5/16-18 socket
head cap screws. Verify that that there are two screws
1-inch long and two screws 1-3/4 inches long (Figure
16, View A).
Securing the Pedestal
WARNING: BOLTING THE PEDESTAL TO THE
FLOOR IS STRONGLY RECOMMENDED. THE
PEDESTAL IS BOLTED TO THE FLOOR TO
ELIMINATE THE POSSIBILITY OF TIP-OVER
WHILE THE MACHINE IS BEING OPERATED.
FAILURE TO DO SO CAN RESULT IN INJURY
TO THE OPERATOR AND/OR OTHER NEARBY
PERSONNEL.
The pedestal has four mounting holes in its base.
Use these mounting holes to secure the pedestal to
the floor before installing the grinder. Shims should
be used to level the pedestal before the attaching
bolts are tightened.
Assembly
WARNING: THE MACHINE MOUNTING PLATE IS
NOT CENTERED ON THE LEG OF THE PEDES-
TAL. THIS OFFSET EVENLY DISTRIBUTES
THE WEIGHT OF THE GRINDING MACHINE.
Small Diameter Contact Wheels
Small diameter contact wheels are useful for grinding
or contouring difficult, hard to reach areas (refer to
Figure 15). The small diameter contact wheels are
available in several sizes. Refer to Figure 14 for a
listing of small diameter contact wheels.
Figure 15: Contouring Using Small
Diameter Contact Wheel
Figure 14: Small Diameter Contact Wheels.
MAKE SURE THE GRINDING MACHINE IS
CORRECTLY POSITIONED AND SECURED TO
THE PEDESTAL BEFORE LEAVING THE
MACHINE UNATTENDED. FAILURE TO COR-
RECTLY POSITION AND SECURE THE MA-
CHINE COULD RESULT IN THE MACHINE
TIPPING OVER, CAUSING INJURY TO PER-
SONNEL.
There are four mounting holes in the mounting plate on
the pedestal. The holes on the motor side of the machine
are approximately 20 inches apart. The holes on the
belt-guard side of the machine are located approximately
½-inch from the corners of the plate. When correctly
installed, all four screw holes in the machine base plate
and belt guard will align with the holes in the mounting
plate of the pedestal.
Mounting Procedure
A. Using two people or a hoisting device, lift the grind-
ing machine and set it on the pedestal. Align all
four screw holes in the machine base plate and
belt guard with the holes in the mounting plate of
the pedestal (Figure 16, View B).
B. Open the grinding belt guard door (Figure 16, View
C). Install two 5/16-18 x 1-inch long screws in the
base of the grinding belt guard. Install screws
finger-tight.
C. Install the two 5/16-18 x 1-3/4-inch long screws in
the screw holes on the motor side of the machine
base (Figure 16, View D). Tighten all four screws.
