This torque wrench is designed solely for bolt tightening purposes, not for loosening.
Using for loosening can apply excessive torque, damaging the wrench and causing injury.
Oil or grease on the grip can cause slipping, leading to accidents or injuries during operation.
Check for cracks, scratches, or rust. Damaged wrenches may cause injury; seek repair if found.
Ensure the ratchet lever is fully engaged. Partial engagement can damage the ratchet and cause accidents.
When working at heights, secure the wrench to prevent dropping, which can cause serious accidents.
Extending the handle with a pipe can damage the wrench and affect its accuracy.
Do not use momentum, body weight, or jerking motions when pulling the wrench to avoid damage or injury.
Do not exceed the maximum torque setting to prevent damage and potential injury.
Do not use adapters to reduce the square drive size, as this compromises strength and causes damage.
Do not use if parts like pins or scale plates are missing; seek inspection and repair before use.
Modifications can weaken the wrench, leading to accuracy errors and potential accidents.
Dropping or shocking the wrench can cause deformation, reduce accuracy, and lower durability.
Do not stand the wrench on end to prevent it from falling or dropping, which may cause accidents.
Only use Tohnichi designated parts for repairs. Contact the seller or Tohnichi for assistance.
Do not apply grease inside the head to prevent ratchet slippage and damage.
Always set the torque correctly before use; it ships set to the minimum scale.
Never set the torque below the minimum scale mark indicated on the wrench.
Ensure the desired torque falls within the wrench's specified scale range for accurate operation.
Verify that the correct unit of measure (e.g., N·m) is selected before applying torque.
Do not use in fresh or sea water, as internal mechanisms can degrade, causing accidents or injury.
Use sockets that precisely match the bolt's hex size to prevent damage and ensure proper grip.
Hold the handle on the indicated effective length line for accurate torque measurement.
Cease tightening immediately upon hearing the click. Overtorquing can cause damage.
Maintain sufficient clearance around the wrench to prevent hand or elbow injuries.
Never use the torque wrench as a hammer or lever, as this can cause deformation and inaccuracy.
Align adjuster marks with grip end cap marks, pull adjuster, and turn to set desired torque.
Attach the appropriate socket securely to the bolt head or nut before applying torque.
Turn the wrench clockwise (as indicated on the tube) to tighten the bolt or nut.
Stop pulling the wrench once you hear the audible 'click' indicating torque has been reached.
Regular inspections and calibration are essential for ensuring function and accuracy.
Apply force perpendicular (within ±15°) to the torque wrench for correct loading.
Remove dirt, dust, oil, and water after each use to prevent malfunction and accuracy issues.
Store at minimum setting with rustproof oil in a dry place to maintain accuracy and durability.
