Model BTW201 can compete with the existing 360W class
AC tool, Mod.6904VH in max. fastening torque.
And its BPM. Pre-selection System prevents the over-tightening.

Features and benefits P 2 / 9
BPM. pre-selection system
The machine stops automatically, when the equipped
bpm. sensor perceives the pre-select bpm.
And the over tightening can be avoided with
BPM. pre-selection system.
Consequently, Mod.BTW201 is suitable for fastening work
in the section where the fastening torque is directed in advance.

(View from terminal side)
226mm
Compact overall length : only 226 mm 200 N.m is the most strongest
fastening torque among
cordless machines, and
same as Mod.6904VH, 360 W AC tool.
Newly developed 24V Ni-MH batteries
(B2417 / 1.7 Ah and B2430 / 3.0 Ah) can
be used for Mod.BTW201.

BPM. pre-select dial
The first digit
The second digit
(The alphabet means
working mode for
special employment.)
BPM. pre-select dial is located in the grip end
as illustrated above,
and it can be found easily, when the battery
is taken off.
BPM. can be set by turning the dial
with flat head screwdriver so that the dial's arrow
align with the numbers or alphabet indicated on the
machine's body.
The figures mean as illustrated in Fig.A - Fig.C.
See next page.

Features and benefits P 3 / 9
If you want 196 bpm., align the pre-setting dial of the second
digit with 9 and the same of the first digit with 8 as illustrated
in Fig.A. Namely, 98 x 2 = 196 bpm.

Special purpose
Dial pre-selection Clockwise rotation Anti-clockwise rotation
Mode of reverse switch
If the dial of second digit is set on "A", the machine does not
start in spite of pulling trigger switch, or setting the dial of
first digit on any numbers.
Purpose
The machine stops after the
sensor perceives the first blow,
depending on the pre-selected
figures of the first digit.
For instance,
0 : Stop at one
1 : Stop 0.1 sec. later
2 : Stop 0.2 sec. later
9 : Stop 0.9 sec. later
The machine starts or stops
with operation of the trigger
switch.
Preliminary fastening
of bolts
The machine starts or stops
with operation of the trigger
switch.
Loosening of bolts
The machine stops after
stopping its blow, depending
on the pre-selected figures
of the first digit. For instance,
0 : Stop at one
1 : Stop 0.1 sec. later
2 : Stop 0.2 sec. later
9 : Stop 0.9 sec. later

0 : stop with one time hitting
1 : stop with two times hitting
2 : stop with three times hitting
9 : stop with ten times hitting
If the dial of second digit is set on "F" and the same of the first
digit is set on zero or one, the following matters are informed.
0 : information of the version code of program
* Version code 2.1 : two long buzzers - long pause,
- one short buzzer
* Version code 3.2 : three long buzzers - long pause,
- two short buzzers
1 : information of the remaining voltage as follows.
* 23 V : two long buzzers - long pause - three short buzzers
* 20 V : two long buzzers
* 18 V : one long buzzer - long pause - eight short buzzers
* 9 V : nine short buzzers
