(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a
while.
CAUTION
When the battery charger has been continuosly
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes rest
until the next charging.
If the battery is recharged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
map light in green.
The battery will not be recharged. In such a case,
let the battery cool before charging.
When the pilot lamp flickers in red (at 0.2-second
intervals), check for and take out any foreign objects
in the charger's battery installation hole. If there are
no foreign objects, it is probable that the battery
or charger is malfunctioning. Take it to your
authorized Service Center.
PRIOR TO OPERATION
1. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it
is at all loose it could come off and cause an
accident.
3. Setting the forward/reverse switching button
(1) Push the forward/reverse switching button from the
right as shown in Fig. 5 (a). Cutting is possible.
(2) By setting the forward/reverse switching button in
the lock position as shown in Fig. 5 (b), the motor
will not operate even if the trigger switch is pulled.
When carrying or storing the main unit or when
stopping operations, set the forward/reverse
switching button to the lock position (Fig. 5 (b)).
(3) Push the forward/reverse switching button from the
left as shown in Fig. 5 (c). With the button held
down, pull the trigger switch so that the cutter can
be removed from the stud. Only set to this position
if the rechargeable battery is worn out and the unit
stops operating during cutting. Immediately turn off
the switch after the cutter has been removed from
the stud.
CAUTION
Do not attempt to cut in the reverse position (Fig.
5 (c)). If you attempt to cut in this position, there
will be an overload on the motor and cutting will
not be possible. Never apply excessive force to the
main unit as this can cause damage to the unit.
4. Check the cutter size, attachment direction,
attachment bolt and spacer
(1) The cutter size differs according to the size of the
studs to be cut. Make sure that a cutter is attached
that conforms to the size of the studs to be cut.
(2) Cutter attachment includes directionality. Make sure
that the cutter has been attached so that the side
without the notch on the cutter can be seen on
bracket (A) (movable side) when the main unit is
viewed from the front or that the notch on the cutter
surface can be seen on bracket (B) (fixed side).

(3) Use the accessory hexagonal wrench to insure that
the hex. socket hd. bolt for attaching the cutter is
securely tightened (Fig. 6). Using the equipment
while the bolt is loose could cause damage to the
main unit and cutter.
(4) Depending on the size of the studs it may be
necessary to attach special spacers to the cutter.
1 When using the M10, M8 or M6 cutter
Check and confirm that the accessory M6, M8 or
M10 spacers are correctly inserted respectively
between bracket (A) and the cutter and bracket (B)
and the cutter (Fig. 6).
CAUTION
If the spacers are not attached or if spacers of the
wrong size are used, the threads of the cutter and
the studs will not properly mesh, thereby causing
damage to the studs and the cutter edge. Be sure
to attach spacers correctly.
2 When using the W3/8" cutter
No spacers are required. Check and confirm that
only the cutter is attached.
For details, refer to the section on "Cutter life and
replacement".
5. Correctly insert the stud guide
The stud guide is used to prevent tilting during
cutting of studs. Correctly adjust the dial calibration
to the mark ( ) depending on the size of the stud
to be cut (Fig. 7).
CAUTION
If the size of the stud and the dial position to do
not agree, the cut section may be subjected to burrs
or its shape may be distorted, which may result in
damage to the main unit.
HOW TO USE
CAUTION
Never bring the cutter near your fingers when
operating the trigger switch.
When cutting short studs, take caution as to not
place your fingers in the space between the short
stud and main unit, such as the guard section (see
Fig. 8), battery, etc.
After cutting, the cut section of the stud is very
sharp and therefore dangerous. Be very careful
when handling the stud.
1. Normal Cutting Method
(1) Pull the trigger switch and move bracket (A), stopping
with the cutter in the open position shown in Fig.
8.
(2) As shown in Fig. 9, set the stud to be cut in the
cutter on the bracket (B) side, making sure that the
threads correctly mesh with each other.
(3) While maintaining the stud in a horizontal position,
pull the trigger switch all the way to cut the stud
(Fig. 8).
(4) After cutting turn off the switch with bracket (A)
facing directly upward. The unit stops with the
cutter in the open position, thus making it easier
to proceed to the next operation.
2. Number of cuttings (per battery charging)
Refer to the chart below for the number of cuttings
per battery charging.
