EXTENSIONS & ADAPTERS
When using an extension or adapter
(increasing the e ective lenght of the
torque wrench) the output torque value
wil change. To calculate the new torque
output of the wrench use the following
formula:
A = L + C x B
L
A = torque exerted at end of adapter
L = distance between square drive and
hand position
B = wrench scale reading
C = lenght of adapter or extension
A number of variables including the
lenght of the adapter or extension,
lenght of the wrench and variations in
hand position on the wrench will a ect
the accuracy oh the above calculation.
INSTRUCTIONS
We calibrate each torque wrench at
the factory using torques standards
according to DIN ISO 6789 2017-1
standard, and certifi es it meets the
accuracy requirements of specifi cations
DIN ISO 6789 and ASME B107. 14M-
2004.

SAFETY
WARNING
Risk of fl ying particles
• Never use torque wrench to break
loose fasteners
• Never use torque wrench as a level bar
• Use of damaged hand tools, sockets,
extentions and accessories may result
in injury
• Do not use torque wrench as a
hammer
• Torque wrenches not in calibration
may cause damage to to parts or tools
• Do not use extensions on handle as
damage to torque wrench will result
• Over tightening of fasteners may
result in breakage
Always use eye protection while using
hand tools
WARNING
Injury may result from electrical shock
Handle is not insulated, do not use on
live electrical or high voltage circuits.

CARE & MAINTENANCE
1. The torque wrench is a precision
instrument and should be stored with
care. Don't throw it around use hammer
with it, or use it as a level bar.
2. The torque wrench is lubricated for
life and should not be oiled. The only
exeption is the ratched head wich may
be lubricated as needed for smooth
operation.
3. Calibration must be done regulary
to ensure accuracy and it's the owner's
responsibility. Suggested
period is at least every 12 months or
even shorter depending on situation.
4. Always store the torque wrench in
the box after use to stay away from dirt
and humidity.
5. Never disassemble
wrench by yourself. For any need to
disassemble the torque wrench or
repair it, please look for assistance from
qualifi ed service station. Any incorrect
action to disassemble
wrench may result in damage of this
instrument.
