battery pack may create a risk offire 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 bums.
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.
Additional Specific Safety Rules
• Hold power tool by insulated gripping surfaces, when
performing an operation where the fastener may contact
hidden wiring. Fasteners contacting a "live" wire may make
exposed metal parts of the power tool "live" and could give the
operator an electric shock.
• Use clamps or other practical way to secure and support
the workpiece to a stable platform. Holding the work by hand
or against your body is unstable and may lead to loss of control.
• Wear safety goggles or other eye protection. Hammering and
drilling operations cause chips to fly. Flying particles can cause
permanent eye damage.
• Accessories and tools get hot during operation. Wearg/oves
when touching them.
• Do not operate this tool for long periods of time. Vibration
caused by tool action may be harmful to your hands and arms.
Use gloves to provide extra cushion and limit exposure by taking
frequent rest periods.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
_ WARNING: ALWAYS use safety glasses. Everyday eyeglasses are
NOT safety glasses. Also use face or dust mask if cutting operation is
dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI $12.6 ($3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
A 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.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.
