SUGGESTIONS

Proper use of this professional torque wrench will give you
complete satisfaction in its performance and reliability. Following
are some helpful tips:

1. Greater torque accuracy is assured by gripping it properly.
Grasp the GRIP, not the SHAFT, and pull smoothly.

2. Each torque wrench is lubricated before leaving the factory. If it
has not been used for some time, it should be operated several
times to re-distribute the lubricant within the working
mechanism.

3. Never attempt to turn the GRIP when the LOCK RING is in the
"LOCK" position.

4. Never set for higher or lower torque values than those indicated
on your wrench.

5. For greater accuracy, clean all thread surf
burrs on the fasteners being used.

6. WARNING- Never use your torque wrench to apply more
torque than its rated capacity.

7. It is not necessary to return this wrench to its lowest calibrated
value after use unless it is to be stored for an extended period
of time.

DO NOT OVERTORQUE

aces and remove any

This torque wrench is certified to be calibrated prior to
shipment to accuracy of +/-4% in the right hand direction on
readings 20% to 100% of capacity. On readings below 20% of
capacity, the accuracy is +/- two scale increments

CERTIFICATION

REPAIR AND CALIBRATION SERVICE

All torque wrenches should have periodic accuracy checks

and recalibration as required. This should be done at least
once a year or every 5000 torque application cycles,
whichever comes first.

Recalibration is also recommended after any abnormal
handling. For service send the wrench to one of the
Warranty Centers listed above of contact our Customer
Service department at [phone] for a list of additional

OPERATING INSTRUCTIONS

1. STUDY THIS BOOKLET CAREFULLY
BEFORE ATTEMPTING TO OPERATE THIS
WRENCH.

2. NEVER APPLY MORE TORQUE THAN THE
MAXIMUM SCALE SETTING.

3. This Torque Wrench is designed for manual
tightening of threaded fasteners only. DO
NOT USE IT AS A NUT-BREAKER OR FOR
ANY OTHER PURPOSE.

4. Over torqued or defective fasteners and
sockets may suddenly break. Ratchets on
plain drives that are improperly engages,
worn out, damaged or over torqued, may
slip or break. TO PREVENT INJURY, KEEP
PROPER FOOTING AND BALANCE AT ALL
TIMES.
PLACES FROM WHICH YOU MAY FALL OR
SLIP OR AROUND ROTATING MACHINERY.

5. This wrench will not prevent you from
applying more torque than set, it is not a
torque limiting tool. Learn how different
amounts of torque “feel”, so you will reduce
the possibility of damage and/or injury due
to accidental over torquing.

6. APPLY FORCE TO THE GRIP ONLY. DO
NOT USE “CHEATER BARS” (A Piece of
pipe placed over the hand grip for more
leverage).

7. There are no user-serviceable components
inside the wrench. Disassembling the
wrench or making any adjustments will
result in the lo

EXAMPLES OF TORQUE SETTINGS

NOTE: Many models have both American Standard and Metric

scales on the same wrench.
The MAIN SCALE American Standard graduations are on the

front of the SHAFT and the THIMBLE SCALE graduations are
closest to the beveled edge. The MAIN SCALE Metric

graduations are on the reverse side of the SHAFT and the
THIMBLE SCALE Metric graduations are below the American
Standard graduations.

EXAMPLE - STANDARD
For a torque setting of 94 foot pounds,
rotate GRIP until the "0" on the
THIMBLE SCALE is aligned with the
"90" on the "FT.LB." MAIN SCALE.

Continue rotating GRIP clockwise until
the "4" on the THIMBLE SCALE is
aligned with the center line on the
"FT.LB." MAIN SCALE. The wrench is
now set at 94 foot pounds. Put the
LOCK RING in the lock position before
using.

EXAMPLE - METRIC
For a torque setting of 105.8 Newton
meters rotate the GRIP until the "0" on
the THIMBLE SCALE is aligned with the

104.4 on the "N.m" MAIN SCALE.
Continue rotating the GRIP clockwise

until the 1.4 on the Metric THIMBLE
SCALE is aligned with the center line of
the "N.m" MAIN SCALE.

The wrench is now set at 105.8 N.m
(104.4 +1.4=105.8). Put the LOCK
RING in the lock position be fore using.

HOW TO APPLY TORQUE

1. This Micrometer Adjustable Torque Wrench is designed so that
when force is properly applied to the handgrip, an audible signal
and/or impulse feel will indicate that the desired torque has been
attained. DO NOT-pull beyond this point.

CAUTION: The audible signal and/or impulse feel is an indicator
that the proper torque has been attained. Over torquing beyond
these signals could cause fastener failure.

Additionally, when wrench is set at low end of the torque range, the
degree of signal and impulse will be less than when set at the high
end of the range. Therefore, care must be taken at low end of scale
to hear signal or feel impulse.

2. To properly apply torque, attach socket securely on torque
wrench square drive and position socke t on th e fastener so that
tilting will not occur. Grasp the center of hand grip and apply a
force perpendicular (90 degrees ) to the torque wrench body and
perpendicular (90 degrees) to the center line of the square drive,
socket, and fastener.

NOTE: The common center line of the square drive, socket and
fastener must be maintained while applying a steadily increasing
force as shown in Figure in order to insure accurate torque readings
via an audible signal or impulse feel.

WARNING: Do not tilt torque wrench handle during torquing
operation. Tilting of torque wrench handle can result in inaccurate
torque and/or over-torq uing damage.

2. Turn the fastener down with a smooth and even force applied
to the handle of the torque wrench (as described in fig.). As
turning resistance increases pull more slowly. To assure
accuracy, the fastener must be in motion when the torque
measurement is made.

WARNING: USE OF NON-AXIAL EXTENSIONS THAT CHANGE
THE EFFECTIVE LENGTH OF THE TORQUE WRENCH SUCH
AS CROWFOOT ATTACHMENTS OR UNIVERSAL JOINTS WIL L
CHANGE THE TORQUE BEING APPLIED. DO NOT USE UNTIL
YOU KNOW THE CONSEQUENCES.
