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.
