How to Apply Torque
1. This Electronic Torque Wrench is designed so that when force is properly
applied to the handgrip, a continuous audible signal, the LCD screen display
and vibration in the handle will indicate that the Target Torque or Angle has
M
U been attained. DO NOT pull beyond this point.
NI
C or M
S
U
NI ET
Caution: The audible signal, LCD screen display and vibration in the the handle
C
S
are indicators that the proper torque or angle have been attained. Over torqu-
ET
ing beyond these signals could cause fastener failure.
2. To properly apply torque, attach socket securely on torque wrench square
drive and position socket on fastener so that tilting will not occur. Grasp the
center of hand grip and apply a slow steady increasing force perpendicular
(90 degrees) to the torque wrench body and perpendicular (90 degrees) to the
M
U
NI
lb.ft
C center line of the square drive, socket and fastener.
S
ET
3. Turn the fastener down with a smooth and even force applied to the handle
M
U
NI
of the torque wrench. As turning resistance increases, pull more slowly. To
C . assure accuracy, the fastener must be in motion when the torque measure-
S
ET
ment is made.
WARNING: Any change from the above procedure will result in a change of
torque being applied. This includes standard torque wrenches, flex-head
M torque wrenches, universal joints, and universal sockets. DO NOT USE universal
U
NI
lb.ft
C
S joints or universal sockets due to the complexity of determining the associated
ET
error. If you need angular access, use a flex-head torque wrench.

or workmanship free of charge. Improper use of these products, including but
not limited to the application of excessive force, will affect performance and
may result in injury. The warranty does not apply to wrenches which do not
function properly or within specified accuracy because of wear, improper or
unreasonable use, damage not resulting from defect or malfunction, or which
have been altered. Calibration is warranted for 90 days. This warranty gives you
specific legal rights, and you may also have other rights which vary from state

• Never use the torque wrench with the power off. Always turn on the
torque wrench so the applied torque is measured.
5. Replace End Cap
• Do not press any key while torque is being applied.
• Do not use electronic torque wrench to loosen fasteners.
• Verify the calibration of the wrench if you know or suspect its
capacity has been exceeded.
• Periodic recalibration is required to maintain accuracy.
• Never apply more torque than the maximum wrench capacity or the
maximum fastener specifications.
• Do not immerse in fluids.
• Do not use on live electrical circuits.
• Electrical shock can cause injury. Rubber handle is NOT insulated.
