Differences of the tool performance
between the RB655 and RB650A
Difference RB650A RB655
1 Tying times
per charge
Tying times per charge was
increased by about 40%. This was
achieved by following factors;
1) Improvement of the work
efficiency of the Twisting motor and
Feeding motor.
2) The PC board has new program
which reduces required electric
current.
Thanks to the increase of tying times
per charge, the total tying times per
battery life is also increased by
about 40%
430 to 530
ties
600 to 700
ties
(30% more)
2 Lifetime of the
motors
Twisting motor of RB655 is
brushless motor and its lifetime is
more than 5 times longer than
Twisting motor of RB650A.
Feeding motor of RB655 is regular
motor but work efficiency is
improved.
The lifetime of the Feeding motor of
RB655 is about 25% longer than the
Feeding motor of RB650A.
Twisting
Motor:
70,000 to
100,000 ties
Feeding
Motor:
200,000 to
250,000 ties.
Twisting

500,000 ties or
more.
Feeding
Motor:
250,000 to
300,000 ties.
3 Inside
temperature
of the tool
The heat created by tool operation is
reduced by increase of the work
efficiency of the motors.

194F
(30% less)
4 Performance
in cold
weather
The rotation of the Twisting motor on
RB655 is controlled by PC board.
Also the reduction of the required
electric current enables stable
operation in cold weather.

RB655
Twisting motor of RB655 is DC Brushless motor. The Brushless motor does not have wearing parts and lasts more than 500,000 ties. Also, the Brushless motor requires less electricity and increases tying times per charge. Feeding Motor on RB655 has better efficiency and requires less electricity. NOT interchangeable with Feeding Motor of RB650A. Main board and Sub board is not supplied individualy. White color wire is added for running Brushless motor.

[RB655 Tying times indication mode]
With the beep sound and LED blinks, total tying times can be read without opening tool frame.
Readable tying times: Minimum 1,000 ties Maximum 999,000 ties
How to go to the "Tying times indication mode"
1) Turn the Main Switch off and remove battery. 4) With using a screw driver, keep the Twist Guide Cover open
2) Remove Tie wire from Magazine. as the picture below shows.
3) Set the Torque adjust dial to the position "1". 5) Set the battery to the tool.
6) Keep pulling the trigger and turn the Main Switch on.
How to read the tying times
Tool shows each digit indication first (LED blinks only) followed by number indication (LED and beep).
Example) # of ties is 16,300 ties.
LED blinks : 3 times LED
Beep
LED blinks : 2 times LED
Beep
LED blinks : one time LED
Beep
LED blinks : 2 times
(Rapid)
Sum #1, #2 and #3 = 16,000 ties. (300 ties can not be read with this program. It can be read by Checker box)
After the rapid 2-time blink (#4), tool repeats indication from #1.
#4 End
56
#3 Digit of 1,000
#1
Number indication is
6 times which means
6,000 ties
Note
Number indication is
one time which
means 10,000 ties
No indication
because # of ties
does not reach
100,000.
#2 Digit of 10,000
Then, the tool start showing how many ties has been made with LED blinks and beep sound.
34 89
Digit indication: LED blinks only (No beep)
7
Number indication: LED blinks and beep sound
