CLAS 1-2 42-210Nm 450mm Torque Wrench User Manual

CLAS 1-2 42-210Nm 450mm Torque Wrench

Product Information

Product Name: OM 0790BL Torque Wrench
Specifications: 1/2 inch drive, torque range of 42-210Nm, length of 450mm
Function: The torque wrench is designed to apply a specific amount of torque to fasteners, ensuring proper tightening and preventing over- tightening.

Product Usage Instructions

1. Ajuster (Adjust): Set the desired torque value on the wrench scale by aligning the appropriate measurement with the reference line.
2. Aligner (Align): Position the torque wrench square drive onto the fastener or adapter.
3. Verrouiller (Lock): Lock the collar to prevent accidental adjustment of the torque setting.
4. Appliquez le couple (Apply torque): Apply force to the handle in a smooth and controlled manner until you hear or feel the click, indicating that the desired torque has been reached.

Safety

• Always wear eye protection and gloves while using the torque wrench.
• Do not use the torque wrench on live electrical or high voltage circuits as the handle is not insulated.

Care & Maintenance

• Store the torque wrench with care, avoiding rough handling or using it as a hammer or level bar.
• The wrench is lubricated for life and does not require oiling, except for the ratchet head which may be lubricated as needed for smooth operation.
• Regular calibration is necessary to ensure accuracy. It is the owner’s responsibility to perform calibration at least every 12 months or more frequently depending on the situation.
• After each use, store the torque wrench in its box to protect it from dirt and humidity.
• Do not attempt to disassemble or repair the torque wrench yourself. Seek assistance from a qualified service station for any disassembly or repair needs to prevent damage to the instrument.

Please refer to the user manual for additional information and safety precautions.

EXTENSIONS & ADAPTERS

• When using an extension or adapter (increasing the eff 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 aff ect the accuracy oh the above calculation.
• We calibrate each torque wrench at the factory using torques standards according to DIN ISO 6789 & ASME B107. 14M-2004, and certifi es it meets the accuracy requirements of specifi cations DIN ISO 6789 and ASME B107. 14M-2004.

INSTRUCTIONS

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 calibration 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 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 torque wrench may result in damage of this instrument.
