ASA Electronics 7000 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)
