z
Inserting and removing single or double-ended 1/4” hex bits
. If the bit to be used is 1/4” single-ended hex
bit (double-ended bits can be used normally), first insert the M3X12 round head machine screw supplied with
the screwdriver into the bit opening and screw it in, as shown on the previous page (optional).
z
Hang securely
. During non-operation, the screwdriver should be hung up securely to prevent it from falling
and also to protect the power cord from sudden pulls.
z
Starting and stopping the motor
. Press the trigger (power switch) down to start the screwdriver and release
it to stop.
Important Points
•
•
If the clutch slips when screws are fully tightened (i.e., clicking sound is not heard when torque is reached),
immediately release the trigger (power switch) to prevent the motor from burning out (due to continued power
flow while it is not operating).
If the screwdriver is operating for a long period or if excessive current surges are experienced, the screwdriver
may overheat. In this case, it will switch off automatically. When the heat has dispersed, normal operation
can resume.
z
Changing the Carbon Brush
. When the carbon brush change indicator lights up red, change it as described
below. (
Caution: Always unplug the screwdriver before changing the brush!
) Only use the factory
specification brushes provided with the screwdriver as replacements.
1. Insert a slotted bit with a 3.0mm wide, 1.0mm thick head in the slot on the side of the carbon maintenance
bonnet and lever it up, opening the bonnet.
2. Remove the spring resting on the carbon brush.
3. Lift the copper wire attached to the carbon brush and pull the brush out.
4. Pull out the tip of the copper wire and complete the removal.
5. Insert the new carbon brush following the above steps in reverse order.
After Use
z
Storage and Maintenance
. If you do not plan to use the screwdriver for a long period, unplug it or switch off
the power source. Store the screwdriver in a dry, dust-free place, away from direct sunlight. Inspect and
maintain it periodically to ensure continued functioning.
z
Repair
. If the screwdriver is not operating normally, do not attempt to disassemble it. Contact AIMCO.
