Important Safety Information
SPECIFIC SAFETY RULES
1. Wear ear protectors. Exposure to noise can
cause hearing loss.
2. Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
3. Hold power tools by insulated gripping
surfaces when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a "live" wire will make exposed
metal parts of the tool "live" and shock the
operator.
4. Be aware that this tool is always in an operating
condition, since it does not have to be plugged
into an electrical outlet.
5. If the bit becomes jammed, immediately turn the
trigger switch off to prevent an overload which
can damage the battery pack or motor. Use
reverse motion to loosen jammed bits.
6. Do not operate the Forward/Reverse lever when
the trigger switch is on. The battery will discharge
rapidly and damage to the unit may occur.
7. When storing or carrying the tool, set the Forward/
Reverse lever to the center position (switch lock).
8. Do not strain the tool by holding the speed control
trigger halfway (speed control mode) so that the
motor stops. The protection circuit will activate
and may prevent speed control operation. If this
happens, release the speed control trigger and
squeeze again for normal operation.
9. Be careful not to get dust inside the chuck.
10. Do not touch the rotating parts to avoid injury.
11. Do not use the tool continuously for a long period
of time. Stop using the tool from time to time to
avoid temperature rise and heat overload of the
motor.
12. Do not drop the tool.
13. Do not put the tool on the place where the
chuck is depressed. The bit may come off from
the chuck and fall down when the chuck is
depressed. It may cause injuries.

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
• Arsenic and chromium from chemically-treated
lumber.
To reduce your exposure to these chemicals: work
in a well ventilated area, and work with approved
safety equipment, such as dust masks that are spe-
cially designed to filter out microscopic particles.
