1. 警告 1. Warnings
●
Make sure there is no oil or grease on the grip.
A slip of the hand while tighteninig, may cause
an accident or injury.
●
Do not set the torque driver beyond the maximum
torque capacity.This will cause damage or injury.
●
Check for cracks, scratches and rust. These will
cause damage to the driver and may result in
an injury. If such conditions exist, have a func-
tional test performed and repair if necessary.
●
Do not drop the torque driver or apply a strong
shock or jolt. This will cause damage or defor-
mation as well as decrease the accuracy and du-
rability, which may cause an accident or injury.
●
Do not use the torque driver in the rain, high
temperature or high humidity, this may result
in malfunction due to the rust.
●
Do not use the torque driver where there are
high levels of dirt or dust.

Precautions when Handling
1.
Make sure a torque driver is set correctly
before using. Set torque is its minimum
when delivered.
2. Don’t use without its scale lange.
3.
Don’t set torque below minimum scale torque.
4. Conrm torque is set according to the
correct unit of measure before using.
(kgf.cm, kgf.m, N.m, cN.m etc)
5. Select a proper bit to adapt to the slit of
the screw head. If not correct, the screw
head may be damaged by the bit.
6. Don’t use in water. The inside mecha-
nism will be in malfunction and cause
an accident or injury. If you drop in
water, Repairing is required.
7. Even with rotary slip clutch, extra clicks
will result in clutch engagement wear-
ing and may shorten durability.
8. When storing, keep from dirt, mud, oil
and water, etc.
3. 用途 3. Application
For tightening screws of watches, preci-
sion electoric components, computer, etc.
4. 特長 4. Features
● Adjustable type torque screwdriver.
Easy torque adjustment with scale.
● Enhanced reliability and durability by
adopting toggle clutch torque mechanism.
●
AMRD/BMRD2 is designed to ratchet freely upon
reaching the set torque to prevent over-torque.
● When reaching the set torque, the
break is felt by hand in 15 degrees.
Stop and complete the tightening work
within the 15 degrees. Ideal for torque
management in the field of precision
electric components due to prevention
of the large shock and vibration.
●
Index nger holding feature allows the op-
erator to tighten with precise movements.

6. 使用方法 6. Operating Procedure
1. Hold the knurled part of the main
scale and turn the handle unit the
desired torque is reached.
■ How to set the torque
(1) Turn the handle until the edge of
the minor scale is lined up with the
torque line of the major scale.
(2) Set the vertical torque line of the minor
scale to vertical line of the major scale.
（Refer to “7.Torque Set”）
2. Insert the bit.
＊ For the AMRD/AMLD, push up the
coupler and insert the bit.
＊ For the BMRD/BMLD, push the bit
until the ball in the adapter stays in the
center of bit groove.
3. Insert the tip of the bit into slit of
screwhead.
4. Turn the torque screwdriver clockwise
to tighten.
＊ For AMRD/BMRD2 slips when set
torque reaches.
＊ For AMLD/BMLD2, when reaching
the set torque, the break is felt by hand
in 15 degrees. Stop and complete the
tightening work within the 15 degrees.

1. Figure4 shows the setting of 0.3cN・m
（major scale points 0.3, minor scale
points 0）.
Minor scale has 0.02cN・m of one
graduation, and moves 0.1cN・m
in one roration. Making 4 rotations
clockwise sets 0.7cN・m.
2. From the setting of 0.7cN・m（Fig.5）,
turning the minor scale clockwise to
the scale marking of 0.02 sets 0.72cN・
m（Fig.6）.
3. From the setting of 0.7cN・m, turning
the minor scale counterclockwise to
the scale marking of 0.08 sets 0.68cN・
m（Fig.7）.
