will not light in red. In such a case, first let the
battery cool, then start charging.
When the pilot lamp frickers in red quickly (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.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC14YF / UC14YF2 is taken out, wait for a
minimum of 3 seconds before reinserting it to
continue charging. If the battery is reinserted within
3 seconds, the battery may not be properly charged.

PRIOR TO OPERATION

1. Setting up and checking the work environment
Check if the work environment is suitable by
following the precautions.
2. Confirm that the battery is mounted correctly.
3. Setting the forward/reverse switching button
(1) Push the forward/reverse switching button from the
right as shown in Fig. 4-1. Cutting is possible in
the position.
(2) By setting the forward/reverse switching button in
the (central) position as shown in Fig. 4-2, 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

With the button held down, slowly 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.
If you remove your finger, the forward/reverse
switching button automatically returns to the
position.
CAUTION
Do not attempt to cut in the

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 marking
on the cutter surface can be seen on bracket (A)
(movable side) when the main unit is viewed from
the front or that 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. 5). 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. 5).
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 M6 cutter or 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" on page 8.
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. 6).
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.
