IMPORTANT: Read Before Using.
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
when used with another battery pack.
25. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
26. 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.
27. 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.
14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
15. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving
parts.
16. If devices are provided for the connection of
dust extraction and collection facilities,
ensure these are connected and properly used.
Use of dust collection can reduce dust-related
hazards.
Power tool use and care
Service
17. Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
28. 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.
18. Do not use the power tool if the switch does
not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
19. Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
29. Follow instruction for lubricating and
changing accessories.
30. Keep handles dry, clean and free from oil and
grease.

SAFETY WARNINGS
1.
Hold power tool by insulated gripping
surfaces, when performing an operation where
the fastener may contact hidden wiring.
20. Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
21. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
23. Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the power
tool for operations different from those intended
could result in a hazardous situation.
Fasteners contacting
a
"live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
Wear ear protectors.
Check the socket carefully for wear, cracks or
damage before installation.

5.
Hold the tool firmly.
Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
The proper fastening torque may differ
depending upon the kind or size of the bolt.
Check the torque with a torque wrench.

(3) Do not expose battery cartridge to water
or rain.
A battery short can cause a large current flow,
overheating, possible burns and even
breakdown.
Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50 ﾟ C (122 ﾟ F).
Do not incinerate the battery cartridge even if
it is severely damaged or is completely worn
out. The battery cartridge can explode in a fire.
Be careful not to drop or strike battery.
Do not use a damaged battery.
To install the battery cartridge, hold it so that the
battery cartridge front shape fits to that of the
battery installment opening and slip it into place.
Always insert it all the way until it locks in place with
a little click. If not, it may accidentally fall out of the
tool, causing injury to you or someone around you.
Do not use force when installing the battery
cartridge. If the cartridge does not slide in easily, it
is not being inserted correctly.

without applying excessive pressure on the tool.
Excessive fastening torque may damage the
bolt/nut or socket. Before starting your job, always
perform a test operation to determine the proper
fastening time for your bolt or nut. Especially for the
bolt smaller than M8 (5/16"), perform the above test
operation to prevent the trouble on socket or bolt,
etc.
OPERATION

If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
more than 15 minutes before proceeding with a
fresh battery.

The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.

When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.
< USA solamente >
ADVERTENCIA
Algunos tipos de polvo creados por el lijado, serrado, amolado, taladrado, y
otras actividades de la construccion contienen sustancias quimicas
reconocidas por el Estado de California como causantes de cancer, defectos
de nacimiento y otros peligros de reproduccion. Algunos ejemplos de estos
productos quimicos son:
• plomo de pinturas a base de plomo,
• silice cristalino de ladrillos y cemento y otros productos de albanileria, y
• arsenico y cromo de maderas tratadas quimicamente.
El riesgo al que se expone variara, dependiendo de la frecuencia con la que
realice este tipo de trabajo. Para reducir la exposicion a estos productos
quimicos: trabaje en un area bien ventilada, y pongase el equipo de seguridad
indicado, tal como esas mascaras contra el polvo que estan especialmente
disenadas para filtrar particulas microscopicas.
