Hitachi CL 14DSL Handling Instructions Manual page 11

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 difficult for the nut to enter the cutting
position, either use a wrench to firmly tighten the
nut or use the accessory trimmer to remove the
flange 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 flange and then
rotate in the opposite direction to remove the
trimmer (Fig. 14).
CAUTION:
This trimmer is specially designed for Studs Cutter.
The flange 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 flange.
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 finger 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
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.
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 flange 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 fit 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.
