PRIOR TO OPERATION

1. Setting up and checking the work environment
Check if the work environment is suitable by the
above precautions.

HOW TO USE

1. Installing the bit
Always follow the following procedure to install driver
bit. (Fig. 5)
(1) Pull the guide sleeve forward.
(2) Insert the bit into the hexagonal hole in the socket.
(3) Release the guide sleeve and it returns to its original
position.
CAUTION
If the guide sleeve does not return to its original
position, then the bit is not installed properly.
2. Removing the bit
Please do the opposite point on the method of
installing bit.
3. Confirm that the battery is mounted correctly
4. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn the
bit counterclockwise (See Fig. 6) (The
marks are provided on the body).
5. Switch operation
CAUTION
Before using, confirm that the switch lever returns
to its original position when pulled and then
released. Failure of the switch lever to operate
properly can result in injury.
Do not hang the angle impact driver from a belt
and the like by the switch lever. The angle impact
driver may drop causing an accident. In addition,
this can also damage the switch lever.
When carrying the angle impact driver, confirm
that the lock button is in the OFF position. Carrying
the angle impact driver with the lock switch in the
ON position can cause the switch to inadvertently
be turned on resulting in injury.
Do not carry the angle impact driver by the switch
lever when carrying. This can cause a malfunction.
Be careful not to pinch your finger between the
switch lever and the angle impact driver. This can
cause an injury.
The switch is turned on when the switch lever is
pulled after having slid the lock button to the ON
position, and is turned off when the switch lever is
released. (See Fig. 7)
The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly
and increases as the trigger switch is pulled more.
Always make sure to return the lock button to the
OFF position after using. (See Fig. 7)
NOTE
A buzzing noise is produced when the motor is about
to rotate. This is only a noise, not a machine failure.
Do not use the angle impact driver with the lock
button in an intermediate position. If used with the
lock button in an intermediate position, the switch
may suddenly be turned off while working or suddenly
come on when carrying. When changing the position
of the lock button, slide the lock button until it reliably
reaches and contacts the ON position or OFF position.
Do not change the position of the lock button while
the switch lever is being pulled. Only change the
position of the lock button after having first released
the switch lever.
Do not place the angle impact driver in a manner
such that the switch lever is facing downward. This
can cause the switch to be turned on as a result of
pressing the switch lever.
Do not move the switch lever in the direction opposite
that of the angle impact driver. This can cause a
malfunction.
6. Tightening and loosening screws
Install the bit that matches the screw, line up the bit in
the grooves of the head of the screw, then tighten it.
Push the angle impact driver just enough to keep the
bit fitting the head of the screw.
CAUTION
Applying the angle impact driver for too long tightens
the screw too much and can break it.
Tightening a screw with the angle impact driver at an
R
L
and
angle to that screw can damage the head of the
screw and the proper force will not be transmitted to
the screw.
Tighten with this angle impact driver lined up straight
with the screw.
7. About Remaining Battery Indicator
When pressing the remaining battery indicator switch,
the remaining battery indicator lamp lights and the
battery remaining power can be checked. (Fig. 8)
When releasing your finger from the remaining
battery indicator switch, the remaining battery
indicator lamp goes off. The Table 4 shows the state
of remaining battery indicator lamp and the battery
remaining power.
State of lamp
As the remaining battery indicator shows somewhat
differently depending on ambient temperature and
battery characteristics, read it as a reference.
NOTE
Do not give a strong shock to the switch panel or
break it. It may lead to a trouble.
