PRECAUTIONS ON USING AUTOMATIC
SCREWDRIVER
1. This automatic screwdriver is designed for tightening
screws. Use it only for these operation.
2. One-hand operation is extremely dangerous; hold
the unit firmly with both hands when operating.
3. Use original bits specifically for the automatic
screwdriver.
Use no bits other than the original bits specifically
for the automatic screwdriver. Use of any other bit
can result in screws sticking out and screw feed
malfunctioning.
4. After installing the driver bit, pull lightly out the bit
to make sure that it does not come loose. If the
bit is not installed properly, it can come loose
during use, which can be dangerous.
5. Screw in screws with the main unit held straight.
If the driver is slanted relative to the screw, the
screw head can be damaged and the bit worn.
Moreover, the prescribed torque is not transmitted
to the screw, resulting in screws left sticking out.
Place the drive straight against the screw and screw
in.

PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
6. Use the prescribed screws.
Do not use any other screws. They can cause
abnormal work (screws fallen over or sticking out)
and break downs (screw jamming and bit wear).
7. Protect your eyes with protective glasses.
Always wear protective glasses while working.
Drilling scatters plaster powder and tape dust, which
are dangerous if they get into your eyes.
8. Watch out for wires and pipes in walls and ceilings.
When working on floors, walls, or ceilings, check
for wires and pipes ahead of time. Work carefully
to avoid shocks and explosions.
9. When the screw feed attachment is removed, always
use the correct driver bit for the screw size.
10. When the screw feed attachment is removed, if the
screwdriver is positioned at an angle against the
tightening screw, the head of the screw may be
damaged or the fixed tightening force will not
transfer to the screw. Always position the tightening
screw and the screwdriver at a straight angle and
then tighten the screw.

2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a power receptacle while
the power switch is in the ON position, the power
tool will start operation immediately, which could
cause a serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
5. Preparing the screws
Select screws appropriate to the application.
6. Bit checking and replacement
A No. 2 Plus bit is installed on this machine as a
standard accessory. Always inspect the bit to make
sure it is not damaged. Using worn bits can cause
screw-in malfunctions. Inspect the bit before work
and quickly replace it with a new one when if starts
to wear out. When the bit must be replaced due
to bit damage or any other reason, replace it
according to the instructions in Bit installation and
removal.
