GENERAL SAFETY
RULES-FOR ALL
BATTERY OPER
ATED TOOLS
WARNING!
READ AND UNERSTAND Aa INSTRUCTIONS.
* Failure to follow all instructions listed
below, may result in electric shock,
fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS Work Area
1) Keep your work area Clean and
well lit.
Cluttered benches and dark areas
invite accidents.
2) Do not operate power tools in
expiosive atmospheres, such as in
the presence of fiammabie liquids,
gases, or dust.
Power tools create sparks which may
ignite the dust or fumes.
3) Keep bystanders, children, and
visitors away while operating a
power tool.
Distractions can cause you to lose
control. Make sure that no one is
beneath, or on the other side of the
area when you are working.
Electrical Safety
4) A battery operated tool with integral
batteries or a separate battery pack
must be recharged only with the
specified charger for the battery.
A charger that may be suitable for one
type of battery may create a risk of fire
when used with another battery.
5) Usebattery operated tool only with
specifically designated battery pack.
Use of any other batteries may cre
ate a risk of fire.
Personal Safety
6) Stay alert, watch what you are
doing, and use common sense
when operating a power tool. Do
not use tool while tired or under
the influence of drugs, alcohoi, or
medication.
A moment of inattention while operat
ing power tools may result in serious
personal injury.
7) Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair.
Keep your hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
can be caught in moving parts.
8) Avoid accidental starting. Be sure
switch is in the locked or off posi
tion before inserting battery pack.
Carrying tools with your finger on the
switch or inserting the battery pack
into a tool with the switch on invites
accidents.
9) Remove adjusting keys or wrench
es before turning the tool on.
A wrench or a key that is left attached
to a rotating part of the tool may
result in personal injury.
10) Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enable
better control of the tool in unexpected
situations.
11 ) Use safety equipment. Always wear
eye protection.
Dust mask, non-skid safety shoes,
hard hat, or hearing protection must
be used for appropriate conditions.
Tool use and care
12) 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.
-2-
Page 3
13) Do not force tool. Use the correct
tool for your application.
The correct tool will do the job better
and safer at the rate for which it is
designed.
14) Do not use tool if switch does not
turn it on or off.
A toot that cannot be controlled with
the switch is dangerous and must be
repaired.
15) Disconnect battery pack from tool
or place the switch in the locked or
off position before making any
adjustments, changing acces
sories, or storing the tool.
Such preventive safety measures
reduce the risk of starting the tool acci
dentally.
16) Store idle tools out of reach of
children and other untrained per
sons.
Tools are dangerous in the hands of
untrained users.
17) 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 con
nection from one terminal to
another.
Shorting the battery terminals togeth
er may cause sparks, bums or a fire.
18) Maintain tools with care. Keep cut
ting tools sharp and clean.
Properly maintained tools with sharp
cutting edge are less likely to bind
and are easier to control.
19) Check for misalignment or binding
of moving parts, breakage of parts,
and any other condition that may
affect the tool’s operations. If dam
aged, have the tool serviced before
using.
Many accidents are caused by poorly
maintained tools.
20) Use only accessories that are rec
ommended by the manufacturer
for your model.
Accessories that may be suitable for
one tool may create a risk of injury
when used on another tool.
Service
21) Tool service must be performed
only by qualified repair personnel.
Service or maintenance performed by
unqualified personnel may result in a
risk of injury.
22) When servicing a tool, use only
identical replacement parts. Follow
instructions in the Maintenance
section of this manual.
Use of unauthorized parts or failure to
follow Maintenance Instructions may
create a risk of shock or injury.
SPECIFIC SAFE
TY RULES
1) Hold tool by insulated gripping
surfaces when performing an
operation where the cutting tool
may contact hidden wiring.
Contact with a “live” wire will also
make exposed metal parts of the tool
