(2) Insert the stud used as a fi xed length guide in the stud
attachment hole found on the main unit stud guide and
use the hexagonal bar wrench to tighten and secure
the hex. socket hd. bolt. Adjust at this time so that the
distance between the end of the stud used as a fi xed
length and the cutter is the necessary length.
(3) Insert the stud for cutting in the cutter, aligning the end
with that of the stud used as a cutting guide, and then cut
the stud.
4. Cutting studs that are already secured (Fig. 11)
When cutting studs that are suspended from the ceiling
or secured to walls or fl oors.
When inserting the stud in the cutter, the meshing of
the stud thread and cutter thread is unstable. In such
a case, after inserting the stud in the cutter, lightly pull
the trigger switch to close the cutter at low speed and
then completely mesh the stud and the upper and lower
cutters. Next, pull the trigger switch all the way to cut the
stud.
CAUTION
Use your one hand to hold the stud on the side released
by cutting to insure that it does not fall unexpectedly.
5. Removing the screw from the unit during cutting
operations
If the battery wears out during cutting operations so that
the motor stops rotating, pull the trigger switch while
pushing the forward/reverse switching button to the
reverse side (Fig. 5 (c)). The motor will rotate in the
opposite direction and it will be possible to remove the
stud from the cutter(Fig. 12).
CAUTION
○ When removing a stud that is suspended from the
ceiling, hold the main unit with both hands to prevent
any possibility of the stud falling.
○ Immediately turn off the switch once the cutter is free
from the stud. If you attempt to do this with the switch
turned on, the cutter might cut into the stud again.
6. Using the hook
The hook can be used to hang up the unit temporarily
during operations (Fig. 13).
CAUTION
The hook should never be used to hang the unit on your
person.
When using the hook, check to make sure that the main
unit will not slip and fall, or become unstable by the wind,
etc.
Never hang the unit from your belt or trousers as this
could cause accidents.
NOTE:
During normal use or during storage, store the hook in the
latch found on the bottom of the main unit.
7. Using the trimmer
NOTE: Use a special trimmer that is suitable for the size
of the stud.
If it is diffi cult for the nut to enter the cutting position,
either use a wrench to fi rmly tighten the nut or use the
accessory trimmer to remove the fl ange on the screw
thread.
Insert the stud in the hole on the grip. Use a pliers to
retain the stud and rotate the trimmer 5 or 6 times to the
right to remove the fl ange and then rotate in the opposite
direction to remove the trimmer (Fig. 14).
CAUTION
This trimmer is specially designed for Studs Cutter. The
fl ange on studs cut with a hacksaw or disc grinder is too
large for this trimmer so that the trimmer does not rotate
and it is not possible to remove fl ange.
8. 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. 15) When
releasing your fi nger from the remaining battery indicator
switch, the remaining battery indicator lamp goes off . The
Table 5 shows the state of remaining battery indicator
lamp and the battery remaining power.
State of lamp Battery Remaining Power
The battery remaining power is
enough.
The battery remaining power is a half.
The battery remaining power is nearly
empty.
Re-charge the battery soonest
possible.
As the remaining battery indicator shows somewhat
diff erently 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.
○ To save the battery power consumption, the remaining
battery indicator lamp lights while pressing the remaining
battery indicator switch.
CUTTER LIFE AND REPLACEMENT
1. Cutter life
As is shown in Fig. 17, repeated cutting can cause
breaking and warping of the cutter edge. Using the
cutter in this condition can produce fl ange on the cutting
location of the studs so that the threads are distorted.
This will prevent clean cuts and make it impossible to
insert the nut.
Breaking
As is shown in Fig. 18, the edge is found on four locations
on the cutter. Use the method described below to change
the attachment direction of the cutter to allow a total of
four usages.
If the nut does not fi t on the screw due to breaking and
warping of the edge, change the cutter attachment
direction to use the edge without breaking and warping
or replace with a new cutter.
