accident or injury.
• Check the product for any crack, flaw or rust.
Crack, flaw or rust may damage the product, resulting in an accident or injury.
Have it checked and repaired.
• Do not use this product for tightening work at a high place.
Dropping of the torque wrench or socket may cause a serious accident or injury.
• Do not extend the handle by connecting a pipe, etc.
It may damage the torque wrench or cause an accuracy failure.
Caution
• When applying force by hand to the torque wrench, do not use your weight or momentum or
do not step on the torque wrench.
The torque wrench may be damaged or bolts may come off, resulting in an accident or injury.
• Do not use the product with a torque exceeding the maximum torque value.
It may damage the product, resulting in an accident or injury.
• Do not use a torque wrench with any missing part, for example, no pin or no scale plate.
Contact your nearest distributor or TOHNICHI MFG. CO., LTD. and have it inspected or repaired.
• Do not modify the torque wrench.
Modifications may decrease the strength or cause an accuracy failure, resulting in an accident or injury.
• Do not drop the torque wrench or give a strong impact to it.
It may damage or deform the torque wrench and cause degradation of the accuracy and the
durability, resulting in an accident or injury.
• Before you turn around having a large torque wrench in your hand, look around carefully.
Turning around without looking around carefully may result in an accident or injury.
• Do not place the torque wrench in an upright position.
The torque wrench may fall down or drop, causing an accident or injury.

Precautions for Use
1. Do not use the product to measure out of its torque scale.
2. Do not set the value under the minimum graduation.
3. Before use, be sure to set the torque value.
The factory default is the minimum graduation value.
4. Be careful not to mistake the unit of torque measurement. (N·m, kgf·cm, etc.)
Before use, check the unit of torque measurement.
5. Do not use the torque wrench in water or in the sea.
It may deteriorate the internal structure, leading to an accident or injury.
If you drop the torque wrench in water or in the sea, have it inspected or repaired.
6. Before using this product for tightening work at a high place, take a measure to prevent it
from dropping.
Dropping of the torque wrench or socket may cause a serious accident or injury.
7. Use sockets which fit the hexagonal sides of bolts.
Using sockets that do not fit the hexagonal sides of bolts may result in an accident or injury.
8. Apply torque gripping the handle of torque wrench on the effective length line.
Unless you grip the handle on the effective length line, a correct torque value cannot be applied.
9. Stop tightening when you hear a "click" sound.
If you continue tightening after a click sound, excessive torque will be applied.
10. When using the product in a limited space, be careful not to be injured in your hand or elbow.
When operating the torque wrench, be careful not to bump your hand or elbow against the
surrounding objects.
11. Do not use the torque wrench as a substitute for hammer or leverage.
If the head or tube is deformed, a malfunction occurs, causing an adverse affect on the accuracy.
12. Be sure to conduct a periodic inspection.
The torque wrench needs a periodic inspection.
13. Direction of force
Apply force in the direction at right angles to the torque wrench.
Keep the vertical and horizontal angles within ±15 degrees of the right angles to the torque
wrench.
14. After use of the product, remove dirt, dust, mud, oil, water, etc., and then store it.
If the soiled product is stored, a malfunction or an accuracy failure may occur.
15. Before the torque wrench is kept unused for a long time, set the torque value to the
minimum, apply rust-proof oil, and store it in a dry place.
Improper storing expedites degradation in the accuracy and the durability.
