Click-Type Torque (Sensing) Wrenches
OPERATING INSTRUCTIONS FOR MICROMETER
ADJUSTABLE TORQUE SENSING WRENCHES
This Torque Sensing Wrench is designed with the user in
mind. It automatically signals by SOUND and IMPULSE when
your desired torque is reached. This wrench is the result of
many years of research by Cooper Power Tools and if given
proper care should provide many years of satisfactory service.
This wrench is calibrated for both right hand (clockwise) and
left hand (counter clockwise) torque application. The TCI-
600FRN and TCI-7250R are calibrated right hand only.

TO SET AT A TORQUE:

To Unlock: Pull back the automatic Lock Collar and hold in
the rearmost position.
While holding the Lock Collar in this position advance the
Handle up the Barrel by turning it in a clockwise direction. (To
move the Handle down the Barrel turn it in a clockwise
direction.) The Barrel is marked in even increments of torque
and one complete turn of the Handle will advance the torque
one complete barrel increment.
If the Barrel is marked in increments of ten, each complete
turn of the Handle would advance one Barrel increment, i.e.
from 10 to 20. The Sleeve Die is marked around the
circumference with the intermediate increments between the
10 and the 20.
The Sleeve Die markings start at 10 and are evenly divided
into ten marks. Every other mark is numbered. To set at an
even Barrel increment the zero marking on the Sleeve Die
should line up with the down center of the Barrel marking (See
Fig.2) Now by advancing the Handle one Sleeve Die mark you
have increased the torque an amount equal to 1/10th the
increase between two Barrel increments (see Fig. 3).
If the Barrel increments were 10, 20, etc. and the original

setting was 10, by moving the Handle on Sleeve Die
increment you increase the torque an amount equal to 1 and
your total torque would be equal to the Barrel marking plus the
Sleeve Die marking or 10 plus 1 equals 11. If you turned the
Handle four Sleeve Die marks in a clockwise direction from
zero you have advanced the torque 4 increments and your
total torque (if the original setting was 10) would be 10 plus 4
equals 14 (See Fig.4).

TO RELOCK:

When you have lined up a Sleeve Die marking with the line
down the center of the Barrel, you can release the Lock Collar
and it will automatically move forward and lock the Handle to
the Barrel.

TO USE:

Attach the appropriate socket wrench, or adapter to the torque
wrench square drive and apply the wrench to the fastener to
be tightened. Hold the torque wrench by the padded handle at
the end of the wrench and tighten the fastener. As the final
tightening of the faster is approached, apply force with a
steady, smooth action.
Do not apply force by holding any part of the wrench, other
than the padded handle. Do not use an extension or other
lever aid on the handle. When the set torque is reached, the
wrench will momentarily release with a feel impulse and
audible click. The wrench will move freely through a small arc
of approximately two (2) degrees. At this point the set torque
has been achieved and force on the handle must be released.
The wrench will automatically snap back to it's original
position and be ready for the next torque application.
Note: When set at the lower torque range, the audible signal
will be much lower. However, there is an audible sound which
in conjunction with the feel impulse should present no difficulty
in operating the wrench at low scale settings.
