Tohnichi Motor Tork Interchangable Type Preset Torque Wrench

Tohnichi Motor Tork Interchangable Type Preset Torque Wrench

Tohnichi Motor Tork Interchangable Type Preset Torque Wrench

Features
For motorcycle maintenance and general use.
Clamp a general tightening tool on MT70N to make it a torque wrench.
Attractive Chrome surface.
Basic open end spanner, ring spanner, ratchet head wrench and hex wrenches can be mounted on this model.(shown with ring head wrench not included)
MT70N covers a wide range of torque from 10N • m - 70N • m.
By incorporating a standard wheel wrench onto the MT70N, it can be used to tighten motorcycle wheel nuts.
A clear "click" sound signals tightening completion upon reaching the set torque.
Torque is adjustable with the tool provided.
Comfortable resin grip.

Maintenance
Torque wrenches are measurement tools.
With a proper daily use and maintenance, adequate performance can be maintained.
Before use, be sure to check the operation and make sure that it properly works.
1) Periodic inspection of torque wrench
The Moto Tork is maintenance-free. However, it is recommended to conduct a periodic torque calibration.
2) Request for repair
The Moto Tork needs repair if the following symptoms appear:
(1) It does not operate (no click sound is heard) even if the set torque is reached.
(2) It is impossible to clamp a tool.
(3) It is impossible to set a torque.
(4) Even after the torque value is changed, the tightening torque is not changed.

Screw Tightening Control
The torque control method is broadly used for controlling the tightening of screws.
According to the torque control method, the axial force (N) is produced by the tightening torque (T).
If the tightening torque (T) is insufficient, the following problems occur due to insufficient axial force (N):
1. The tightened object is not held stationary and it moves unsteadily. (A long-time loading causes looseness.)
2. The tightened objects are not held enclosed, resulting in a leakage. (A leak of oil, etc. is caused.)
3. The thermal conductivity of tightened objects becomes low, and they are heated. (Heattransfer efficiency is reduced.)
4. The screw itself is not held stationary and it becomes loosened. (The screw is loosened and comes off.)
If the tightening torque (T) is excessive, the following problems occur:
1. Bolts or nuts are damaged.
2. The tightened object is damaged. (Especially, aluminum parts, etc.)
3. The bearing surface collapses. (Aluminum parts, low-intensity parts)
Thus, it is necessary to tighten screws with a proper tightening torque.

Warnings
• Do not use this product for any other purpose than to tighten bolts. This product is a torque wrench designed for tightening bolts.
• Keep the grip handle free of oil, grease, etc. Oil or grease on the grip handle causes a slip of hand during tightening work, resulting in an 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.

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
