GENERAL POWER TOOL
SAFETY WARNINGS
WARNING
Read all safety warnings, instructions, illustrations and specica-
tions provided with this power tool. Failure to
follow all instructions listed below may result in
electric shock, re and/or serious injury. Save all
warnings and instructions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-oper-
ated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodied plugs and matching outlets will
reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock.
• When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of an GFCI reduces
the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the inuence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
• Use personal protective equipment. Always wear
eye protection. Protective equipment such as a dust
mask, non-skid safety shoes, hard hat or hearing
protection used for appropriate conditions will reduce
personal injuries.
• Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your nger on the
switch or energizing power tools that have the switch
on invites accidents.
• Remove any adjusting key or wrench before 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.
• Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry or long hair can
be caught in moving parts.
• 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.
• Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
• 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.
• 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.
• Disconnect the plug from the power source and/
or remove the battery pack, if detachable, 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.
• 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. Pow-
er tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. 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.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
• Us
e 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.
• Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used
with another battery pack.
• Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and re.
• 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 re.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact accidentally occurs, ush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
3
• Do not use a battery pack or tool that is damaged or
modied. Damaged or modied batteries may exhibit
unpredictable behavior resulting in re, explosion or
risk of injury.
• Do not expose a battery pack or tool to re or excessive temperature. Exposure to re or temperature
above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specied in the instructions. Charging im-
properly or at temperatures outside the specied range
may damage the battery and increase the risk of re.
SERVICE
•
Have your power tool serviced by a qualied repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
CIRCULAR SAW
Cutting procedures
•
DANGER
Keep hands away from cutting area
and the blade. Keep your second
hand on auxiliary handle, or motor housing. If both
hands are holding the saw, they cannot be cut by the
blade.
• Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
• Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
• Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable platform.
It is important to support the work properly to minimize
body exposure, blade binding, or loss of control.
• Hold the power tool by insulated gripping surfaces
only, 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 power tool “live” and could give the operator
an electric shock.
• When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
• Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw
will run eccentrically, causing loss of control.
• Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and
safety of operation.
Further safety instructions for all saws
Kickback causes and related warnings
- Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to
lift up and out of the workpiece toward the operator;
- When the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;
- If the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into
the top surface of the wood causing the blade to climb
out of the kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below:
• Maintain a rm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade, but
not in line with the blade. Kickback could cause the
saw to jump backwards, but kickback forces can be
controlled by the operator, if proper precautions are
taken.
• When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the
blade comes to a complete stop. Never attempt
to remove the saw from the work or pull the saw
backward while the blade is in motion or kickback
may occur. Investigate and take corrective actions
to eliminate the cause of blade binding.
• When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw teeth
are not engaged into the material. If saw blade is
binding, it may walk up or kickback from the workpiece
as the saw is restarted.
• Support large panels to minimise the risk of blade
pinching and kickback. Large panels tend to sag
under their own weight. Supports must be placed
under the panel on both sides, near the line of cut
and near the edge of the panel.
• Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
• Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
• Use extra caution when sawing into existing walls
or other blind areas. The protruding blade may cut
objects that can cause kickback.
Lower guard function
• Check lower guard for proper closing before each
use. Do not operate the saw if lower guard does
not move freely and close instantly . Never clamp
or tie the lower guard into the open position. If saw
is accidentally dropped, lower guard may be bent.
Raise the lower guard with the retracting handle and
make sure it moves freely and does not touch the
blade or any other part, in all angles and depths of cut.
• Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
• Lower guard should be retracted manually only
for special cuts such as “plunge cuts” and “compound cuts.” Raise lower guard by retracting handle
and as soon as blade enters the material, the lower
guard must be released. For all other sawing, the
lower guard should operate automatically.
• Alw
ays observe that the lower guard is covering
the blade before placing saw down on bench or
oor. An unprotected, coasting blade will cause the
saw to walk backwards, cutting whatever is in its
path. Be aware of the time it takes for the blade to
stop after switch is released.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
