Clamp Head Installation
The post of the string clamp head and tube of
the string clamp base are treated with grease
to provide protection against corrosion during
shipping. Remove any excessive grease with
a clean cloth prior to use. The post and tube
may also be cleaned with isopropyl alcohol.
After this type of thorough cleaning, the post
and tube should be treated with a light coating
of machine oil to protect the surfaces against
corrosion and to ensure smooth operation.
ASSEMBLY INSTRUCTIONS
Installing the Tensioner
Remove the button head screw and washer
located at the end of the tensioner bar with
the 3 mm hex wrench provided. Slide the

the bar with all of the bearings and the drive
gear with the gear track. Replace the screw
and washer into the end of the tensioner bar.
Note:
The tensioner bar is equipped with
a tensioner travel stop to limit travel of the
tensioner along the bar. See page 10 for

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 6mm 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 6mm 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.
