HOW TO USE
(cont.)
■ Fastening torque
The torque exercised on a screw fastened to an actual workpiece generally differs
from the torque of the screwdriver measured by a torque gauge.
* This is because the work conditions differ between when using an actual
workpiece and when measuring torque with a torque gauge.
Torque exercised on a screw changes depending on the work conditions.
(E.g., screw size/material, workpiece material, presence of pilot hole, finished
condition, working posture, etc.)
■ Recommended method to set the clutch step and manage (store) the
torque
There are two kinds of torque to manage (store): "torque (A) exercised on a screw
fastened to an actual workpiece" and "torque (B) of the screwdriver".
① Fasten a screw to an actual workpiece
using the screwdriver
② Using a gauge that can measure the
torque exercised on the fastened screw,
check the difference from the set torque
( by means of loosening torque check,
refastening torque check, etc.)
③ Repeat setting of the clutch step to find
the one with a smallest difference
➡ To store the torque indicated by the
gauge, i.e. the "torque (A) exercised
on a screw fastened to an actual
workpiece"
④ With the clutch step found above,
measure the torque of the screwdriver
using a torque gauge
➡ To store the torque indicated by the
torque gauge, i.e. the "torque (B) of
the screwdriver"
* The conditions in ③ and ④ differ, resulting in different torque.
("Torque (A) exercised on a screw fastened to an actual workpiece" in ③ ≠
"torque (B) of the screwdriver" in ④ )
* Perform measurement more than once taking into account variation in the work
conditions.
* Perform measurement periodically as the work conditions may change over time.

Starting Work
Set the rotation direction
with the forward/reverse
lever.
When you set it to the "F" position
and the "R" position, the motor
rotates forward (clockwise) and
reverses (anticlockwise)
respectively.
R position
F position
Forward (Clockwise)
Reverse (Anticlockwise)
NOTE
If the forward/reverse lever is
switched while the motor is in action,
the motor is forcibly stopped to rotate.
Start rotation.
In "lever start" mode, pull the lever.
In "push start" mode, push toward
the bit.
Lever start
Push start
There may be a slight delay in the
rotation startup at the start, but it
is not a failure.
In case of quick ON/OFF, the
rotation startup will be late a little
for that.
You can select "lever start" or
"push start" for start mode.
