ASA Electronics 8000 User manual

□ After use
Storage and maintenance: when the unit is to be stored for a long period, remove the power supply and bit, open the carbon brush
cover and blow out any accumulated carbon brush dust with compressed air, and wipe the exterior clean. Then store the screwdriver
carefully in a dry, dust-free place away from direct sunlight. Store the bit in grease. To ensure continued serviceability, periodically
check and maintain the screwdriver.

□ Troubleshooting
If the screwdriver does not work properly, check the list below. If you cannot solve the problem do not open the unit. Contact one
of our authorized agents as soon as possible.
□ If the screwdriver does not run
˙Check that the power supply is outputting power.
。Check that the power supply plug is inserted properly and that output plug terminals No.1 (-) and
NO.4 (+) show 30VDC (approximate) between them. If no output is shown, change the power supply.
。Check for a open or short circuit in the 5p-5p or 6p-6p cord connecting the screwdriver to the power
supply.
If an open or short circuit is found change the cord or plug.
(use plug type 2G2021(5p) or 2G2022(6p) or purchase equivalent type)
。check that the fuse is intact. Caution: when changing the fuse, unplug the power supply.
˙check that the carbon brush is undamaged, that the carbon brush guide cord with the rotor to become too
small. Anyone of these factors could cause the screwdriver to stop rotating or rotate abnormally.
Inspection method: open the carbon brush cover and use a non-conductive insulated rod to gently press the
brush. If the screwdriver resumes rotating, the carbon brush has reached the end of its useful life and must be
replaced immediately.
˙Check that the rotation direction switch are working properly. If no ‘click’is heard when a trigger is
depressed, it is not working and must be replaced.
(make sure to perform this check in a quiet place)
□ If the screwdriver is not rotating normally
˙There is a protective circuit within the power supply. Power is only supplied normally from 3 to 5 seconds
after current flow begins.
˙If the motor only runs intermittently during ‘Forward’operation, try ‘Reverse’ operation, or rotate the anvil
90 degrees until a ‘click’is heard, then re-attempt ‘Forward’ operation.
˙Long-term use causes the motor’s commutator to wear down. In this case, it must be replaced.
(this repair must be performed by one of our authorized agents)
□ If the bit falls out easily or wobbles
˙check that the bit matches our specifications. If not, change the bit to one that does.
˙If the bit tends to wobble, remove the bit, rotate it 60 or 180 degrees and re-insert it.
□ If the screwdriver does not stop when the selected torque is reached
˙An excessive torque setting can cause the screw to strip the threads, with the result that the clutch does not
activate. Lower the torque to a level that does not cause stripping.
˙Differences in size between the bit tip and screw slot lengths can cause slopping. Change to a suitable bit tip.
˙The brake circuit may be damaged or the sensor switch may have shifted.
(this repair must be performed by one of our authorized agents)

․APS-35A/APS-35E are switching circuit power supplies. They are light and small, consume little electricity
and supply stabile voltage.
․Stabilizer accessories：2 locking ties, 2 pieces of double-sides tape(only for APS-35A/APS-35E)
□Before use, read the following
□ Use the correct voltage: Carefully check the voltage shown on the power supply and this manual and
determine the correct voltage. Only plug the unit into a power source of the correct voltage.
□ Determine the appropriate torque range: choose the correct screwdriver for the torque you will require. To
lengthen product life, avoid long-term high torque use.
□ Make sure the screwdriver is undamaged: If the power code is scraped or damaged, it should be immediately
unplugged and replaced to avoid electric shocks or a short circuit that could result in fire.
□ Use in an appropriate work environment: To ensure safety, do not use in high temperature, high humidity
environments or near flammable materials. Keep the power cord away from tools or equipment that might
scrape or melt it.
□ When plugging in or unplugging the power cord, hold the plug firmly. Never pull on the cord.
□ Method of operation and important points
□ Brace fastened objects securely-Before operation, refer to “torque settings” item to determine the
appropriate torque , and adjust the screwdriver to the appropriate torque. Make sure that the
fastend objects are securely braced, and then begin operation. This procedure will avoid
hazardous rapid rotation of the fastened objects due to excessive torque or insufficient bracing.
□ Driving and removing screw: Before operation, set forward/reverse switch properly. To drive
a screw, set the switch to the forward(FOR) position. To remove a screw, set it to the reverse(REV) position.
Press the screwdriver onto the screw perpendicularly to being operation. Note: Don’t operate the FWD/REV
switch when the motor is running.
□ Torque settings: Use the regulating handle or torque reaction ring (ASA-8500, 9000 only) to set the torque.
Turning it in a clockwise direction into the screwdriver will increase the torque. Turning it counterclockwise
out of the screwdriver will decrease the torque.
Note: The engraved markings on the engraving ring are for reference only and do not indicate torque output.
Torque output can only be determined by repeated testing with a torque meter or hand-held spanner torque
meter. To prevent your torque setting from being changed, we can provide a torque cover (optional) which
covers and secures the regulating handle.
□ Bit insertion: Use your finger to depress the slide sleeve into the screwdriver and insert an appropriate bit.
When the slide sleeve is released, the bit will be automatically engaged.
Note: Do not hammer the bit in or pull it out forcibly.
□ Secure screwdriver during operation: During operation, hang the screwdriver up securely (as from balancer) in
order to prevent it from being knocked down and suffering external cracking, internal damage, or a snapped
power cord.
□ Start and stop: For lever start type. The motor begins running when the lever is depressed and stops when it is
released. For push to start type. When the screwdriver is pressed onto a screw perpendicularly, inwards
pressure from the screwdriver bit engages the power switch, and the motor begins running. When the pressure
on the screwdriver is released, the bit and power switch revert to their original positions and the motor stops
running.
□ When the selected torque is reached: This product features an internal clutch assembly. When a screw is driven
and the selected torque is reached, the clutch assembly will automatically disengage and a ‘click’ will be heard.
At this point, even if the ‘trigger’lever or depress force is not released, the power to the motor will be
automatically cut off.
Note: When driving screw, grasp the screwdriver firmly in order to prevent upwards recoil generated by the
clutch release from forcing the screwdriver bit edge form the screw slot and damaging slot.
□ When removing screws: when a previously driven screw cannot be removed using the same torque that it was
driven with, raise the torque setting. After the screw is removed, return the regulating handle to its original
setting. To simplify this operation, note the number ‘click’sounds generated as the regulating handle is turned.
When removing a screw, if the required torque is higher than the screwdriver’s output torque, the clutch may
not disengage, causing the user’s hand and arm to be twisted. In this case immediately set the forward/reverse
switch to “STOP” to cut the motor power and prevent injury.
□ Operational frequency: suggest the operational frequency 1/4”(ON/OFF)second, the total screws
7000pcs/8hours, don’t over our operational frequency suggest, and avoid the inside parts of screwdriver serious
damage. If everyday work 8hours upward, please use two screwdriver by turns, protect the life of screwdrivers.
□ Changing the carbon brush: Open the carbon brush cover by turning it counterclockwise with a coin or standard
screwdriver(width5-7mm.)Remove the used carbon brush and insert a new carbon brush of the same
specifications in the empty space. To complete the operation, close the carbon brush cover tightly by turning it
clockwise. Then remove the carbon brush fastener
Note:
․When changing the carbon brush first unplug the screwdriver. Use a factory specification carbon brush.
․The notch on the carbon brush surface must face into the direction of the rotor rotation
