MAINTENANCE & ADJUSTMENTS

Adjusting the Tensioner Brake

After  stringing  many  racquets,  the  brake 
of the tensioner may need to be adjusted. 
With the brake lever engaged in the latch, 
insert the 5mm allen wrench into the bolt (A) 
located at the base of the brake lever.  It can be 
accessed through the hole on the face of the 
tensioner cover (above the ‘GAMMA’ logo).

Note: 

The tensioner cover does not need to 

be removed for the adjustment.  The cover 
has been removed in the pictures for illustra-
tion purposes.

To tighten the braking mechanism, turn the 
set screw (A) counter clockwise by about 1/8 
turn. Re-tighten the allen screw (B) on the 
back side of the tensioner frame and check 
for  brake  tightness.  The  tensioner  should 
move freely along the track with the brake 
lever engaged and should hold tension with 
the brake lever released. If more adjustment 
is needed, repeat steps above until properly 
adjusted.

While holding the 5mm brake lever adjust-
ment bolt (A), loosen the hex bolt (B) located 
on the back side of the tensioner frame with 
the 4 mm allen wrench. 

Note:

 The hex bolt should only be loosened  

and must not be completely removed.
