5) Battery tool use and care
a) Recharge only with the charger specified by the
manufacturer.
A charger that is suitable for one type of battery
pack may create a risk of fire when used with
another battery pack.
b) Use power tools only with specifically designated
battery packs.
Use of any other battery packs may create a risk
of injury and fire.
c) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal
to another.
Shorting the battery terminals together may
cause burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause
irritation or burns.
6) Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.
PRECAUTIONS FOR CORDLESS STUD
CUTTER
1. Never bring the cutter near your fingers when
operating the switch.
2. Do not use for cutting screws other than soft steel
studs. This tool is designed especially for cutting
of soft steel studs. Using this tool for brass or
stainless steel screws could cause distortions in
the screw threads, thereby preventing insertion of
nuts.
Never use to cut tempered bolts, screws of differing
sizes, reinforcing rods, etc.
3. Use by changing the special cutters according to
the size of the studs. Cutting with cutters of the
wrong size could damage to the continuous thread
studs or the cutter edges.
4. Make sure that the threads on the studs and those
on the cutter are correctly meshed before starting
to cut. Cutting when the threads are not meshed
could cause damage to the studs and the cutter.
5. If the cutter has been attached in the wrong
direction or the bolt for cutter attachment is loose,
this could cause damage to the cutter edge and
could lead to premature damage to the main unit.
Be very careful to attach the cutter correctly.
6. Cutting studs at short lengths of 10 millimeters
or less will create an insufficient meshing length
between the cutter and studs, thus causing damage
to the cutter. Always cut at lengths of more than
10 millimeters.

7. When cutting studs secured to narrow locations,
be sure that there is at least 8 millimeters between
the stud and the surrounding materials.
If the distance is less than 8 millimeters the cutter
could contact the surrounding materials, thereby
causing damage to the cutter and the main unit.
8. When inspecting, cleaning or replacing the cutter,
be sure to remove the battery from the main unit.
The switch could be turned on accidentally, thereby
causing accidents.
9. When using this equipment at heights, make
doubly sure prior to use that there is no one
standing in the area immediately below you. Place
the tool in a safe and stable place when not using
at the moment.
10. Always charge the battery at a temperature of 0
– 40°C. A temperature of less than 0°C will result
in over charging which is dangerous. The battery
cannot be charged at a temperature greater than
40°C. The most suitable temperature for charging
is that of 20 – 25°C.
11. Do not use the charger continuously.
When one charging is completed, leave the charger
for about 15 minutes before the next charging of
battery.
12. Do not charge the battery for more than 1 hour.
The battery will be fully charged in about 1 hour
and charging should be stopped when 1 hour has
elapsed from commencement. Disconnect the
charger power cord from the receptacle.
13. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
14. Never disassemble the rechargeable battery and
charger.
15. Never short-circuit the rechargeable battery.
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage
to the battery.
16. Do not dispose of the battery in fire.
If the battery is burnt, it may explode.
17. When drilling in wall, floor or ceiling, check for
buried electric power cord, etc.
18. Bring the battery to the shop from which it was
purchased as soon as the post-charging battery
life becomes too short for practical use. Do not
dispose of the exhausted battery.
19. Using an exhausted battery will damage the
charger.
20. Do not insert object into the air ventilation slots
of the charger.
Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical
shock hazard or damaged charger.
