Pre-Lock Adjustable Torque Wrench
Torque set is changed by using a standard hex key to adjust setting on scale
This creates a more secure torque setting, in comparison to QL types which have a large knob
Suitable for mass production as single purpose with graduation.
A clear "Click" sound signals tightening completion upon reaching the set torque.
The ratchet head has 24 teeth with a 15 degree operating range, allowing for use in space-limited working conditions.
Applicable for international use including the EU region. Compliant with calibration procedures of ISO 6789 Type II Class A.
Do's And Don'ts
Don't use your weight when using torque wrench, because this may result in loss of control, with possible injury is wrench comes off of the bolt.
Do use fluid and steady motion. Jerking or unsteady movement may damage the wrench.
Don't use an adapter to reduce the square drive size. This may result in over-stressing of the square drive, and slippage that may lead to injury.
Do inspect the wrench before each use, and ask a Tohnichi-authorized repair center to inspect or repair it if any parts are missing or damaged.
Don't modify the wrench, or use a wrench that has any modifications except those approved by Tohnichi. Other modifications will weaken the wrench, or cause inaccuracy, as well as causing damage or possible injury.
Do take care to avoid shocks or jolts, including dropping the wrench. Damage or deformation may result, and accuracy and durability will be reduced.
Do take careful note of your surroundings when handling a large-capacity torque wrench. Twisting or falling while using a large torque wrench can cause injury, possibly serious in nature, if the user is not alert and careful.
Do always store the torque wrench properly. Place it in its original container or a tool container designed for that purpose, and never stand it on end. Failure to follow this advice may result in reduced wrench life, and increases risk of injury.
Do use only parts approved by Tohnichi for repair and maintenance of the torque wrench. Ask your place of purchase, an authorized repair center, or contact Tohnichi for assistance in obtaining parts or repairs.
Do not apply grease inside head to prevent ratchet from slipping. It may cause unexpected injury and damage on ratchet.
Proper use of torque wrench
Check the setting of the wrench before use. The wrench is set at the minimum torque setting when shipped.
Do not set torque below minimum scale torque.
Use the wrench within the scale range.
Make sure that the proper measurement unit (kgf.cm, kgf.m, NM, lbf.in, etc.) is used in setting the wrench.
Avoid submersion in water. Water will cause damage to internal components and ruin the wrench.
Only use a socket in the proper hex size for the bolt being tightened.
The torque wrench handle has an effective-length mark, which must be used to grip it in the proper place. Improper grip position will reduce accuracy.
A click will signal that the proper amount of torque has been applied. Pay careful attention, and stop tightening when the click is heard or felt.
Use the torque wrench only where there is sufficient clearance and freedom of movement. You may select another wrench, if necessary.
Never use the torque wrench as a hammer or mallet.
Have the torque wrench inspected periodically by someone qualified for that purpose to insure accuracy and proper functioning.
Torque wrenches are required periodical inspection.
The loading direction must be at a right angle to the torque wrench. The tolerance is plus/minus 15 degrees of horizontal or vertical deviation.
Before using or storing the wrench, or whenever necessary, remove all debris, oil, water, etc. Keeping the wrench clean will prolong its life.
If the wrench must be stored for long periods, set the wrench at the minimum torque, apply rust-proofing oil, and store the wrench in a dry place. Improper storage may cause damage to the wrench, and reduce the accuracy.
How to set the torque
1. Insert a Allen wrench into a adjusting hole.
2. Turn the Allen wrench clockwise to add torque value, and turn counter-clockwise to reduce torque value. Read main and supplementary graduation for your desired torque value.
