MAINTENANCE & ADJUSTMENTS

If the lever releases before 60 lbs., using 
the supplied L-shaped hex wrench, turn 
the adjustment screw (B) located on the left 
side of the latch block counter-clockwise to 
increase the engagement of the brake release 
latch with the brake lever. Repeat step 1 and 
adjust until the correct tension is indicated 
on the calibrator.
If the tension indicated in step 1 is greater 
than 60 lbs., turn the adjustment screw clock-
wise to reduce the engagement of the brake 
release latch with the brake lever. Repeat 
step 1 and adjust until the correct tension is 
indicated on the calibrator.

Loosen the 1.5 mm locking set screw (A) 
located on the side of the latching block as 
shown. The set screw is used to hold the 
adjustment screw in place.

Tension Calibration Procedure

Set the tension to 60 lbs. as indicated by the 
linear scale and rotary knob. Place the string 
on one end of a tension calibrator into a string 
clamp and secure. Place string located on 
the other end of the calibrator into the string 
tensioner and apply tension. If the brake lever 
releases before or after 60 lbs., the tension 
head should be calibrated as follows.

Adjusting the Frame Support Posts

Loosen the lock bolts of the frame support 
posts and space them apart with the frame 
support slides separated by the approximate 
length of the racquet head. Although it is not 
required, it is good practice to center the sup-
port posts on the turntable. Lock one of the 
posts in position by tightening the lock bolt and 
position the other post until the frame support 
slide is positioned near the inside surface of 
the racquet frame. Securely tighten the lock 
bolt of the second support post.

Caution

: To avoid racquet damage, the 

center posts should not contact the racquet prior to locking down the support posts.

MOUNTING THE FRAME

Tightening the Frame Supports

Tighten the Frame Support Slides by turn-
ing the adjustment knob clockwise until 
snug against the racquet frame and slight 
resistance is felt.

Caution:

 Overtightening the Center Supports 

will stretch the head of the racquet and could 
cause racquet damage.  

Frame Shoulder Support Adjustment

Being sure the shoulder supports are free 
to swivel in their mountings, simultaneously 
rotate the shoulder support adjustment knobs 
clockwise until both shoulder supports gently 
and squarely contact the frame.
