CLAS 3-8 5-50Nm TORQUE WRENCH 3/8″ D User Guide
EXTENSIONS & ADAPTERS
When using an extension or adapter (increasing the effective length 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 afect
the accuracy oh the above calculation
We calibrate each torque wrench atthe factory using torques standards
according to DIN ISO 6789 & ASME B107.300-2010, and certifi es it meets the
accuracy requirements of specifi cations DIN ISO 6789 & ASME B107.300-2010.

SAFETY
WARNING
Risk of flying 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
- 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.
- 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.
- Calibration must be done regulary to ensure accuracy and it’s the owner’s responsibility. Suggested calibration period is at least every 12 months or even shorter depending 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 qualifi ed service station. Any incorrect action to disassemble the torquewrench may result in damage of this instrument
