A torque wrench is used to apply a specific, predetermined rotational force (torque) to a fastener, such as a bolt or nut. This ensures fasteners are tightened correctly, preventing them from being too loose (which can cause failure) or too tight (which can cause damage).
Always store the wrench at its lowest torque setting (25 Nm) to relieve tension on the internal spring. Clean the wrench regularly and avoid dropping it. For critical applications, it's recommended to have torque wrenches calibrated annually or after a significant impact.
While the drive mechanism can turn in both directions, torque wrenches are designed and calibrated for tightening. Using it for loosening may affect its accuracy over time. It is best practice to use a standard ratchet for loosening fasteners.
This means the actual torque applied will be within 4% of the value you set on the scale. For example, if you set it to 100 Nm, the actual torque applied will be between 96 Nm and 104 Nm.
A dual-scale reading allows you to measure torque in two different units: Newton-meters (Nm) and Inch-pounds (In.lb). This provides flexibility as different applications or specifications may call for one unit over the other.
The 3/8 adapter allows you to use 3/8-inch drive sockets with this 1/2-inch drive torque wrench. Simply insert the 3/8 end of the adapter into the 1/2-inch drive socket on the wrench, and then attach your 3/8 socket to the other end of the adapter.
Ensure the lock knob is fully released and the scale is correctly set. Verify the torque setting is within the wrench's 25-225 Nm range. If the issue persists, the internal mechanism may require servicing.
Make sure to pull the lock knob down completely before rotating the handle. If the knob is stiff, check for any debris around the mechanism.
Clean the laser-etched scale with a soft, dry cloth. Ensure adequate lighting when reading the scale. If damage is visible, professional calibration or replacement may be needed.
This could indicate a need for internal lubrication or servicing. Clean the exterior and store it properly; if the feeling persists, consult a professional.
Setup: To set the desired torque, pull down the lock knob at the end of the handle and rotate the handle until the laser-etched scale aligns with the target torque value. Once set, release the lock knob to secure the setting. Ensure the wrench is set to its lowest torque setting (25 Nm) before storage.
Compatibility: This wrench features a 1/2-inch drive, making it compatible with standard 1/2-inch drive sockets. A 3/8-inch adapter is included for use with smaller sockets.
Care: Clean the wrench with a soft, dry cloth after use. Avoid exposing it to moisture or harsh chemicals. Store the torque wrench in its provided storage box to protect it from dust and damage. Periodically check the scale for any signs of damage or wear. Always return the torque setting to the lowest value (25 Nm) after use to prolong its lifespan and maintain accuracy.
