stand design. The legs must be assembled
to the Lower Column before use. Remove
all parts from the shipping carton to confirm
that contents match the parts list.
Align the holes in the Leg Flange with the
matching holes in the Lower Column. Se-
cure the leg with one M8x30 flat head screw
through the upper hole, and one M8x35
socket head cap screw through the bottom
hole. Repeat this procedure for the three
remaining legs.

MOUNTING THE FRAME
Mounting Stand Adjustment
When mounting a racquet, adjust the
Mounting Stands so that the white Racquet
Supports on top of the Mounting Stands fit
inside the hoop of the racquet. Lower the
racquet over the Racquet Supports and
adjust the Mounting Stands until the sup-
ports just make contact with the inside sur-
face of the racquet at the head and throat.
There is an arrow on the face of each Ad-
justment Knob on the Turntable indicating
the turning direction that will “Tighten” the
mounting points by moving the 2pt Mount-
ing Stands further apart to bring the Racquet Supports closer to the inside surface of the
racquet at the head and throat. Turning the knobs in the opposite direction will move the
Mounting Stands closer together and will allow the Racquet Supports to move away from
the racquet frame.
Adjusting the Inner Racquet Supports
The white Racquet Supports are adjustable to accom-
modate all racquets and provide maximum support to
the racquet frame. Screw the pads up or down so they
contact the frame at a maximum height without blocking
the grommet holes.
Racquet Hold Down Clamp Operation
With the lever in the up position, insert the Racquet Hold
Down Clamp Pin into the hole in the center of the Mount-
ing Stand. Lower the Hold Down Clamp until it just makes
contact with the surface of the racquet. Using slight palm
pressure on the Hold Down Clamp depress the racquet
Hold Down Lever completely to secure the racquet frame
to the Mounting Stand.

20
MOUNTING THE FRAME
Special Throat Mounting
Racquets with a bridge that is thinner than
the rest of the frame or are tapered from
head to throat require special mounting
to ensure the frame is not damaged. The
white Support Pads need to be moved
from the inside of the racquet bridge to the
throat of the racquet.

String Clamp Operation
The String Clamps are a dual action design
where the String Clamp and Clamp Base
operate independently of one another.
Toclampastring,lifttheStringClampandplace
the string between the jaws and depress the
String Clamp Lever to secure the string. The
clampingpressureappliedtothestringshould
be adjusted to provide sufficient pressure to
securethestringwhensubjectedtothedesired
pulling tension. The textured surface of the
teeth provide for increased friction between
theclamps and thestring toallowfor reduced
clamping pressure while securing and holding the string under tension.
Note that excessive pressure can damage both the strings and String Clamp.
Clamp Base Operation
TolocktheClampBasetotheTurntable,rotate
the Clamp Base locking lever clockwise until
it locks into place. Note that to lock the clamp
base lever, the string clamp must be lifted up
to disengage the release mechanism located
