Torque wrenches are designed for
tightening only. They are not intended
for any other use, including loosening.
Check the handle to make sure it
is free of oil, grease, dirt, or other
contaminants.
A slip of the hand can cause injury or
improper tightening.
Examine wrench for cracks, scratches,
rust, or other damage. These can
cause wrench failure and operator
injury.
If using a ratchet wrench, make sure
it is the correct position. Failure to do
this may result in damage to the ratchet
and injury to the operator.
When you use this wrench in a high
location, prepare to prevent dropping
the wrench.
If you drop the torque wrench or
socket, that may cause a serious
accident or injury.
Do not use pipes, cheater bars, or any
kind of extension on the handle of the
wrench. This will damage the wrench,
and result in inaccuracy.

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 surround-
ings when handling a largecapacity
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 Tohni-
chi 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.

Check the setting of the wrench before
use.
Make sure that the proper measure-
ment unit (kgf cm, kgf m, N m
Ibf 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
effectivelength 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.

Before using or storing the wrench, or
whenever necessary, remove all debris,
oil, water, etc. Keeping the wrench

If the wrench must be stored for
long periods, apply rust-proofing
