■Use a PC to start the uploader program.
■In the uploader program, first select the correct
COM port no.
■Next, select the file path to save the uploaded data.
■Finally, press “upload” button to transmit the
torque records to the PC.
■The uploaded data is then shown on the column
and saved in the *.csv file.
Use Microsoft Excel to view *.csv file.
Cautions:
Refer to the uploader program user guide for
the detail operations.
MAINTENANCE AND STORAGE
BATTERY MAINTENANCE
■When the screwdriver is not going to be used for
an extended period of time, remove the battery.
■Keep a spare battery on hand when going on a
long trip or to cold areas.
■Sweat, oil and water can prevent a battery’s
terminal from making electrical contact.
To avoid this, wipe both terminals before loading a
battery.
■Dispose of batteries in a designated disposal
area. Do not throw batteries into fire.
Caution:
1. Over-torquing (110% of max. torque range)
could cause breakage or lose of accuracy.
2. Do not shake violently or drop screwdriver.
3. Do not use this screwdriver as a hammer.
4. Do not leave this screwdriver in any place
exposed to excessive heat, humidity, or
direct sunlight.
5. Do not use this apparatus in water (it is not

alcohol or paint thinner when cleaning
the screwdriver.
8. Keep this screwdriver away from magnets.
9. Do not expose this screwdriver to dust or
sand as this could cause serious damage.
10. Do not apply excessive force to the LCD
panel.
11. Apply torque slowly and grasp the center
of the handle. Do not apply load to the
end of the handle.
12. When checking the accuracy or calibration,
please use the bit head packed inside the
blow mold case.
Attention!
One-year periodic recalibration is necessary to maintain
accuracy. Please contact your local dealer for calibrations.
