1
Don't apply momentum with your
own weight or use a jerking motion,
when you pull the torque wrench.
This will damage the torque wrench and
may cause the wrench to come off of the
bolt.Resulting in an accident or injury.
2Precautions
2
2
Don't use the torque wrench beyond
the maximum torque setting.
This will cause damage or injury.
3
Don't make the square drive smaller
by using an adapter.
This will create insufficient strength
and cause an accident or injury.
4
Don't use the torque wrench if it is
missing a pin or scale plate, etc.
Ask a repair shop or our company to
inspect the torque wrench and repair
it before using.
5
Don't modify the torque wrench.
Modifications will weaken the torque
wrench.This may cause errors in
accuracy, as well as, cause an
accident or injury.
6
Don't drop the torque wrench or
apply a strong shock or jolt.
This will cause damage or deformation
as well as decrease the accuracy and
durability, which may cause an acci-
dent or injury.
7
Be aware of your surroundings
when handling a large capacity
torque wrench.
Turning or walking while holding a large
torque wrench may cause accident or
injury, if the user is not alert.
8
Don't stand the torque wrench on end.
If may fall or drop,and cause an
accident or injury.
9
Use only parts designated by
Tohnichi for repair of the torque
wrench.
Ask the place of purchase or our
company for assistance when you
repair, and use only Tohnichi parts.
7
Loading direction.
The loading direction must be at right angles
to the torque wrench (tolerance: ).
This tolerance applies to both horizontal
and vertical deviation.
8
Remove any dirt such as dust,mud,oil
and water,etc.after each use and
before storing torque wrench.
3Precautions for use
1
Confirm that the torque is set
according to the correct unit of
measure before using.
(kgfcm, kgf m, N m, etc)
3
2
Don't use torque wrench in fresh
water or sea water.
The inside mechanism will go bad and cause
an accident or injury.If you drop in water or
sea water,get it checked out or repaired.
3
Use the correct socket that fits the
hex size of the bolts,you are using.
If you use an incorrect socket,this
may cause an accident or injury.
4
Make sure there is enough clearance
for your hand and elbow before
using to prevent injury.
5
Don't use the torque wrench as a
hammer.
If there's a deformation on the beam,an
operation failure could result and cause a
decrease in the accuracy of the torque wrench.
6
Perform regular inspections for
function and accuracy.
Periodical inspections are essential to
insure the torque wrench is in optimal
condition thus preventing injury.
9
For models having 25.4mm
square drive, use with a through-
holesocket(pneumatic tool type).
Connecting a socket (manual tool type) having
no through-hole may result in disconnection.
10
Do not use this instrument for a
breaking test.
Using under breaking or rupture test
may result in the needle dose not return
to its Zero point correctly.

5Operating Procedure
T23N-S T1400N-S (230T-S 14000T-S)
Set the main pointer to the 0 position on the
scale plate. (Fig.1) (Rotate the scale plate until
the0 position is aligned with the main pointer.)
For models with a memory pointer, measure
the torque only after setting the memory
pointer to0 position by turning the memory
pointer knob opposite to measuring direction.
Insert the square drive of the wrench into the
required socket.
Apply the socket on to a bolt head or nut.
Apply force to the center of the grip and mea-
sure while watching scale plate.
The T-S wrench is bi-directional.
The measurement can also be made by setting
the main pointer to the desired torque,and
pulling the wrench until the main pointer
reaches0 position on the scale plate. (Fig.2)
T2100N-S T4200N-S (21000T-S 42000T-S)
Attach the extension handle to main wrench.
Confirm that the pin has locked the extension
handle in place.
Set the main pointer to the 0 position on the
scale plate. (Fig.1) (Rocate the scale plate until
the0 position is aligned with the main pointer.)
For models with a memory pointer, measure
the torque only after setting the memory
pointer to0 position by turning the memory
pointer knob opposite to measuring direction.
Insert the square drive of the wrench into the
