below the lowest value (”stop” indicator) nor
above the highest value.

WARNING
RISK OF FLYING PARTICLES
■Do not use the torque wrench to break loose fasteners.
■Do not use torque wrench as a lever bar.
■Use of damaged hand tools, sockets, extensions and accessories may result in injury.
■Do not use the torque wrench as a hammer.
■Torque wrenches not in calibaration may cause damage to parts or tools.
■Do not use extensions on handle.
■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 AND MAINTENANCE
The torque wrench is a precision instrument, and should be stored with care. Do not throw it around, use hammer with it, or use it as a
lever bar.
The torque wrench is lubricated for life and should not be oiled. The only exception is the ratchet head which may be lubricated as
needed for smooth operation.
The torque wrench is a precision measuring instrument. Calibration must be done regularly to ensure accuracy and its’ the owner’s
responsability. Suggested calibration period is at least every 12 months or even shorter dependig on situation.
Always store the torque wrench in the box after use to stay away from dirt and humidity.
Never disassemble the torque wrench by yourself. For any need to disassemble the torque wrench or repair it, please look for assistance
from qualified service station. Any incorrect action to disassemble the torque wrench may result in damage of this instrument.
STANDARD
We calibrate each torque wrench at the factory using torque standards according to DIN ISO 6789 & ASME B107.14M-1994 and certifies
it meets the accuraccy requirements of specifications DIN ISO 6789 and ASME B107.14M-1994.

FORMULA FOR CALCULATING THE EFFECT FOR TORQUE
In case it is impractical to use regular sockets, (for example tightening threaded connectors) and a special attachment must be utilized, then such
attachments change the effect of the torque wrench, and it is necessary to calculate the correct settings with the following formula.
E - Effective length of extension
Lf - Lever length of the wrench: middle of handle to center of square drive
T(W) - Torque setting on the wrench
T(A) - Torque applied by the extension to the fastener
T(A) = T(W) x Lf + E
Lf
