TOHNICHI FTD8N2-S (01) PDF DOCUMENT

The main parts of the TOHNICHI FTD8N2-S series torque driver are:

Bit: The interchangeable tip for engaging with the screw (sold separately as an option).

Main Pointer: The primary needle that indicates the currently applied torque on the scale plate.

Scale Plate: The dial with graduated markings to read the torque value.

Memory Pointer: A secondary pointer (drag pointer) that remains at the peak torque achieved during an operation for easy reading after the force is released.

Handle: The grip used to apply force to the driver.

Before using the TOHNICHI FTD8N2-S, please observe the following warnings to prevent accidents or injury:

Check the Grip: Make sure there is no oil or grease on the grip. A slip of the hand while tightening may cause an accident or injury.

Inspect for Damage: Check the tool for any cracks, scratches, and rust. These conditions can cause damage to the driver and may result in an injury. If such conditions exist, have a functional test performed and repair if necessary.

To maintain the performance and safety of your TOHNICHI FTD8N2-S, follow these precautions:

Do not exceed maximum torque: Do not use the torque driver beyond its maximum torque setting. This will cause damage or injury.

Do not use if incomplete: Do not use the torque driver if it is missing a pin, scale plate, or other parts. Ask a repair shop to inspect and repair it before using.

Do not modify the driver: Modifications will weaken the torque driver. This may cause errors in accuracy, as well as cause an accident or injury.

Avoid impacts: Do not drop the torque driver or apply a strong shock or jolt. This will cause damage or deformation as well as decrease the accuracy and durability.

Use designated parts: Use only parts designated by Tohnichi for repair of the torque driver.

Perform regular inspections: Periodical inspections are essential to ensure the torque driver is in optimal condition, thus preventing injury.

Confirm units: Confirm that the driver is set according to the correct unit of measure before using (e.g., kgf·cm, N·m, etc.).

Use correct bit: Use the correct bit that fits the screw you are using.

Follow these steps for the operating procedure of the TOHNICHI FTD8N2-S Series:

1. Insert the bit or socket into the holder. The TOHNICHI FTD8N2-S model uses a square drive.

2. Set the main pointer to the “0” position on the scale plate. The pointer should be at the “0” position before starting.

3. Move the memory pointer to the “0” position on the side opposite of the measuring direction.

4. Start the measuring or tightening operation. The main pointer will indicate the applied torque, and the memory pointer will remain at the peak torque achieved.

When you attach or detach a bit or a socket, you must hold the shaft of the driver. Do not hold the grip and pull strongly, as the FTD might be broken.

After Use: Remove any dirt such as dust, mud, oil, and water, etc. after each use and before storing.

Long Term Storage: When storing the torque driver for a long time, set it at the minimum torque and keep it in a dry place. If improperly stored, the accuracy and durability will decrease rapidly.

No, do not use the torque driver in fresh water or sea water. The inside mechanism will go bad and cause an accident or injury. If you drop it in water or sea water, get it checked out or repaired.

The following table details the specifications for the S.I. MODEL FTD-S Series, including the TOHNICHI FTD8N2-S. Accuracy is ±3%.

The Torque Driver Tester is an optional accessory used for the inspection and calibration of the torque driver.
