in the main body, such as at right next to a wall
or column, remove the screw feed attachment before
operation. (Fig. 17)
3. Switch operation, changing the direction of rotation
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the push button.
The L-side of the push button is pushed to turn the
bit counterclockwise. (See Fig. 18).
and
marks are indicated on the main body.
By pulling the switch trigger, the rotation speed will
steplessly vary from 0 to 2300 revolutions per minute.
NOTE: When the switch trigger is pulled only
slightly, a beep sound will be heard. This
is the sound of the motor, and it does not
indicate any abnormality.
CAUTION
While the screwdriver is running, the push button
cannot be switched.
To switch it, turn off the screwdriver first.
OPERATIONAL CAUTIONS
1. To screw in screws, hold the driver straight against
the workpiece.
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.
2. When screwing in, press the main body firmly until
the screw is completely screwed in.
Relaxing your pressure on the driver while screwing
in can leave the screw sticking out.
3. Do not you screw in a screw on top of another
screw.
If you do, the screw falls over and the next screw
can not be fed.
4. Precautions for empty strikers:
When you are screwing in colleted screw strips, you
might continue to use the driver without noticing
that you have run out of screws. If you try to screw
in when you are out of screws, the bit can damage
the gypsum board, so while working, keep an eye
on how many screws you have left.
5. When the slider does not move smoothly
Clean the slider, sliding surface of the slider case
and roller of the upper part of the slider. (Fig. 19)
NOTE:
The operator may become covered with plaster
dust quite easily when operation is performed in
an upward direction. Clean the slide surface and
roller periodically during operation.
SCREW HANDLING
NOTE:
Handle both the packed box of screws and the collated
screw strips with care. If you drop them, screws can
come out of the collated tape and cause screw feed
malfunctions. Do not expose the screws to prolonged
periods of direct sunlight or outside air. They can cause
rust and collated tape problems, so when you will not
be using the screws for awhile, put them in the screw
packing box or the like.
MAINTENANCE AND INSPECTION
1. Inspecting the driver bit
Using a broken bit or one with a worn out tip is
dangerous because the bit can slip. Replace it by
a new one.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so may result in serious hazard.
3. Cleaning of the outside
When the automatic screwdriver is stained, wipe
with a soft dry cloth or a cloth moistened with
soapy water. Do not use chloric solvents, gasoline
or paint thinner, as they melt plastics.
4. Inspecting the carbon brushes (Fig. 20)
The motor employs carbon brushes which are
consumable parts.
Since an excessively worn carbon brush can result
in motor trouble, replace the carbon brush with a
new one having the same carbon brush No. shown
in the figure, when it becomes worn to or near the
"wear limit". In addition, always keep carbon brushes
clean and ensure that they slide freely within the
brush holders.
5. Replacing carbon brushes:
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
NOTE
Due to HITACHI's continuing program of research and
development, the specifications herein are subject to

IMPORTANT
Correct connection of the plug
The wires of the mains lead are coloured in accordance
with the following code:
Blue:
– Neutral
Brown:
– Live
As the colours of the wires in the mains lead of this
tool may not correspond with the coloured markings
identifying the terminals in your plug proceed as follows:
The wire coloured blue must be connected to the
terminal marked with the letter N or coloured black.
The wire coloured brown must be connected to the
terminal marked with the letter L or coloured red.
Neither core must be connected to the earth terminal.
NOTE
This requirement is provided according to BRITISH
STANDARD 2769: 1984.
Therefore, the letter code and colour code may not be
