PRECAUTIONS ON USING AUTOMATIC
SCREWDRIVER
1. This automatic screwdriver is designed for
tightening and loosening 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.

APPLICATIONS
Screw driving into indoor gypsum board.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
7
Place the drive straight against the screw and
screw in.
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 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 it 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.
