(9) OK/NG/Beep Sound Indicating Light Explanation
Protection:
1. Protection at low voltage: short beeps come with red-light flashing when enable screwdriver,
and then disable screwdriver that both beeps and red-light flashing keep going for 5 seconds which
means the battery’s voltage now is low. If screwdriver could not be started by pushing it and come
with 2 short/ 1 long beeps plus red-light flashing the battery is now out of power; moreover,
followed by the above situation then release screwdriver from pushing, both beeps and red-light
flashing signs will remain the same. (The screwdriver will not detect battery power when enable
motor and PCBs’ temperature protection.)
CAUTION!!
Low battery indicator on: When low battery protected indicator on, screwdriver can not reach to its
maximum torque setting. Please change battery pack or charge it.
2. Temperature Protection: When red-light begins flashing along with beeps for 9 times the
screwdriver will be locked.
3. Sleep & Power Saving Mode: It will enter sleep mode when the screwdriver stopped for about 5
seconds, press the lever can wake up sleep. The power will be cut off when sleep more than 24
seconds, press the switch can restore power.

Other Cautions
1. The best condition of using the tool is under 8 hours a day, do not over loaded.
cording to operating frequency and torque loaded, we suggest adding lubricating oils in clutch
per 3-6 months, and kindly contact with distributor when product's maintenance.
2. Do not attempt to repair or disassemble this cordless screwdriver without authorization. Always
have the device serviced by assigned factory or qualified person in order to have the warranty
effective continually.
3. SAING EI is not responsible for any poor performance or damage caused by customers own
modification of the tool.
4. It is necessary for the management to have every operator to read and follow all instructions in
this manual. Do not attempt to repair or disassemble this cordless screwdriver themselves.
5. Chemicals, Acetone, Benzene, Alcohol, Thinner, Ketone, trichloroethylene, etc. shall not be in
contact with the surface of the screwdriver in order to prevent chemical damage.
6. Please follow instruction carefully and do not drop or shock the screwdriver.
7. This is an external torque adjustment screwdriver, 0 on the torque adjust ring stands for
minimum torque and 8 for maximum torque. The rated operation time is 1 second / 3seconds
(ON / OFF). Appropriate fastening frequency is 15 fasteners in each minute. Overrunning may
damage motor due to overheat. Proper amount of screwdriver resting is recommended to prevent
motor overheating.
8. The screwdriver could not be used before end of OK/ NG beeps and light signal.
9. For your safety stop operating your screwdriver in any time during torque adjustment and be
aware of mistouch any trigger from your screwdriver.
10. Each operational torque setting, using time and frequency may result in different level of wear
and tear, at higher torque setting and use extensively could accelerate the wearing down of tool.
After one month, the torque is getting reduce gradually at the rate of 2~3% or 3~5 %( max
torque). The longer use of the device, torque reduction will become stable and the users could
measure the torque by a tester on a regular time schedule to check if the torque power still meets
the criteria.
11. The torque range of MYBT-ASP0520 series must be measured by the SAING EI torque meter
KTM-150.
12. SAING EI cordless screwdriver torque output is generated by clutch mechanism, and it is
applicable to ISO 6789.

To adjust the torque on these screwdrivers. Proceed as follows :
1. Determine the torque output of the tool by checking a tightened fastener with a torque wrench.
2. Increase or decrease the torque by rotating torque Adjusting Ring. Rotating the Ring clockwise
to a higher number on the torque Scale increase torque output while rotating the Ring
counterclockwise to a lower number decreases the torque output.
3. Check the adjustment with a torque wrench. A number of factors will affect torque output from
one job to another. Final torque adjustment should be made at the job through a of series of
gradual increase. Always start below the desired torque and work upward.
4. Adjust the bit torque by changing the driving in length of the adjust ring at the end.
5. The relationship between torque scale and bit torque is as shown Ring, in the torque diagram.
The figures of torque scale do not indicate bit torque values. However, the clamping torque of
screw itself is different form type, size, material of the screw and the material of its mating part.
Use it as standard to obtain an appropriate clamping torque.
6. The (Return torque method) in which once-clamped screw is returned with torque wrench or the
like is available as one of torque control methods, however, note that the measured values by the
return torque method generally appear in 10%~30% lower than the actually clamping torque.
7. The torque checker measures the torque of screwdriver. The clamping torque of screw itself is
different from the clamped conditions. Understand the correlation between clamping torque
values and the torque checker values perform the torque control properly.
1. In reverse rotation, the clutch is turned off when a screw is tightened at large torque, set same
or higher torque to unscrew.
2. The number from zero to eight on the Torque Scale are reference number only and not an
indication of actual torque output.
3. Please refer to SAING EI websitehttps://www.mytorqtools.com for the detail component list.
