SAFETY INSTRUCTIONS
WARNING: Read all safety
warnings and instructions.Failure to
follow the warnings and instructions
may result in electric shock, fire 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-operated
(cordless) power tool.
WARNING: Risk of re and
electric shock. Dry location use only.
Do not expose to rain. Risk of injury.
WORK AREA SAFETY
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Do not operate power tools in
explosive atmospheres, such as in the
presence of flammable liquids, gases
or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away
while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
1. 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.
Unmodified plugs and matching outlets
will reduce risk of electric shock.
2. 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.
3. Do not expose power tools to
rain or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
4. Do not abuse the cord. Never
use the cord for carrying, pulling or
unplugging the power tool. Keep the
cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled
cords increase the risk of electric shock.
5. When operating a power tool
outdoors, use an extension cord
suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk
of electric shock.
6. If operating a power tool in a
damp location is unavoidable, use a
ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI
reduces the risk of electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are
doing and use common sense when
operating a power tool. Do not use the
tool while tired or under the influence
of drugs, alcohol, or medication. A
moment of inattention while operating
power tools may result in serious
personal injury.
2. 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.
3. Prevent unintentional starting.
Ensure that 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 finger on the switch or
energizing power tools that have the
switch on invites accidents.

Page 5
4. 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.
5. Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in
unexpected situations.
6. Dress properly. Do not wear loose
clothing or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
7. If devices are provided for the
connection of dust extraction and
collection facilities, ensure that these are
connected and properly used. Use of these
devices can reduce dust-related hazards.
USE AND CARE OF THE
POWER TOOLS
1. Do not force the power tool. Use the
correct power tool for your application. The
correct power tool will do the job better
and more safely at the rate for which it was
designed.
2. 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.
3. 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.
4. 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.
5. 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.
6. Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
7. Use the power tool, accessories,
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.
BATTERY TOOL USE
AND CARE
1. Recharge only with the charger
specified by the manufacturer. A charger
that is suitable for one type of battery pack
may create a risk of fire when used with
another battery pack.
2. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
3. When the battery pack is not in use,
keep it away from other metal objects,
such as 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.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, also seek
medical help. Liquid ejected from the battery
may cause irritation or burns.

SAFETY INSTRUCTIONS
SERVICE
1. 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.
SPECIFIC SAFETY RULES FOR
CIRCULAR SAWS
1. Danger
a) Keep hands away from cutting area
and 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.
b) Do not reach underneath the work
piece. The guard cannot protect you
from the blade below the work piece.
c) Adjust the cutting depth to the
thickness of the work piece.. Less than
a full tooth of the blade teeth should be
visible below the work piece.
d) Never hold piece being cut in your
hands or across your leg. Secure the
work piece to a stable platform. It is
important to support the work properly
to minimize body exposure, blade
binding, or loss of control.
e) Hold power tool by insulated gripping
surfaces when performing an operation
where the cutting tool may contact
hidden wiring or its own cord. Contact
with a ‘live’ wire will also make exposed
metal parts of the power tool ‘live’ and
shock the operator.
f) When ripping always use a rip fence or
straight edge guide. This improves the
accuracy of cut and reduces the chance
of blade binding.
g) Always use blades with correct size
and shape (diamond versus round) of
arbor holes. Blades that do not match
the mounting hardware of the saw will
run eccentrically, causing loss of control.
h) 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.
2. Causes and operator prevention
of kickback
a) kickback is 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;
b) 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;
c) 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 if the wood causing the
blade to climb out the kerf and jump
back toward the operator.
3. Kickback is the result of saw misuse
and/or incorrect operation procedures or
conditions and can be avoided by taking
proper precautions as given below.
a) Maintain a firm 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.
b) 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.
c) When restarting a saw in the work piece,
centre the saw blade in the kerfs and
check that saw teeth are not engaged
into the material. If saw blade is binding,
It may walk up or kickback from the work
piece as the saw is restarted.

Page 7
SAFETY INSTRUCTIONS
d) Support large panels to minimize 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.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerfs causing excessive
friction, blade binding and kickback.
f) 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.
g) Use extra caution when making a
‘plunge cut’ into existing walls or other
blind areas. The protruding blade may
cut objects that can cause kickback.
4. Safety instructions for saws with inner
pendulum guard
a) 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.
b) 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.
c) 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.
Always observe that the lower guard is
covering the blade before placing saw
down on bench or floor. An unprotected,
coasting blade will cause the saw to walk
backwards, cutting whatever is in its path.
Be ware of the time it takes for the blade to
stop after switch is released.

BLADE GUARD SYSTEM (FIG. 2)
The lower blade guard attached to your
saw is there for your protection and safety.
It should never be altered for any reason.
If it becomes damaged or begins to return
slowly, do not operate the saw until the
damaged guard has been repaired or
replaced. Always leave the blade guard in
operating position when using the saw.
DANGER: When sawing through
a workpiece, the lower blade guard does
not cover the blade on the underside of
the workpiece. Since the blade is exposed
on the underside of the workpiece, keep
hands and ngers away from the cutting
area. Any part of your body coming in
contact with the moving blade will result in
serious injury.
CAUTION: Never use the saw when
the blade guard is not operating correctly.
Check the guard for correct operation
before each use. The guard is operating
correctly when it moves freely and readily
returns to the closed position. If you drop
the saw, check the lower blade guard and
bumper for damaged at all depth-of-cut
settings before reuse.

SAW BLADES
All saw blades need to be kept clean, sharp
and properly set in order to cut efciently.
Using a dull blade places a heavy load
on the saw and increases the danger of
kickback. Keep extra blades on hand, so
sharp blades are always available. Gum and
wood pitch hardened on the blade slows the
saw down. Use gum and pitch remover, hot
water or kerosene to remove them. Do not
use gasoline.
KICKBACK (FIG. 3 - FIG. 6)
OPERATION
WARNING: When using the saw,
always stay alert and exercise control. Do
not remove the saw from the workpiece
while the blade is moving.
WARNING: A 6 1/2-inch blade is
the maximum blade capacity of your saw.
A blade larger than 6 1/2-inch will come
in contact with the blade guards. Also,
NEVER use a blade that is so thick that
it prevents the outer blade washer from
engaging with the at side of the spindle.
Blades that are too large or too thick can
result in an accident causing serious injury.

OPERATION
Kickback occurs when the blade stalls
rapidly and the saw is driven back towards
you. Blade stalling is caused by any action
which pinches the blade in the wood.
To guard against kickback, avoid dangerous
practices such as the following:
1. Setting blade depth incorrectly.
2. Sawing into knots or nails in the workpiece.
3. Twisting the blade while making a cut.
4. Making a cut with a dull, gummed up or
improperly set blade.
5. Supporting the workpiece incorrectly.
(See Fig.3)
6. Forcing a cut.
7. Cutting warped or wet lumber.
8. Operating the tool incorrectly or misusing
the tool.
9. Attempting to cut with blade at less than
full speed.
WARNING: If the blade comes
in contact with the workpiece before it
reaches full speed, it could cause the saw
to “kickback” towards you, which could
result in serious injury.
TO LESSEN THE CHANCE
OF KICKBACK, AVOID
DANGEROUS PRACTICES
SUCH AS THE FOLLOWING:
1. Keep the blade at the correct depth setting.
The depth setting should not exceed 1/4
Iinch below the material being cut.
2. Inspect the workpiece for knots or nails
before cutting. Never saw into a knot
or nail.
3. Make straight cuts. Always use a straight
edge guide when rip cutting. This helps
prevent twisting the blade.
4. Use clean, sharp and properly set blades.
Never make cuts with dull blades.
5. Support the workpiece properly before
beginning a cut.
6. Use steady, even pressure when making
a cut. Never force a cut.
7. Do not cut warped or wet lumber
8. Hold the saw rmly with both hands and
keep your body in a balanced position
so as to resist the forces if kickback
should occur.
WARNING: To avoid kickback,
release the switch trigger immediately if
the blade binds or the saw stalls. Kickback
could cause you to lose control of the saw.
Loss of control can lead to serious injury.
LOCK-OFF BUTTON (FIG. 7)
The lock-off button reduces the possibility
of accidental starting. The lock-off button is
located on the handle above the trigger switch.
The lock-off button must be depressed before
you squeeze the trigger switch.

STARTING/STOPPING THE SAW
(FIG. 7)
To start the saw:
1. Depress the lock-off button.
2. Depress the trigger switch. Always let
the blade reach full speed, then guide
the saw into the workpiece.
To stop the saw:
Release the trigger switch.
After you release the trigger switch, allow
the blade to come to a complete stop.Do
not remove the saw from the workpiece
while the blade is moving.
DEPTH OF CUT ADJUSTMENTS
(FIG. 8)
Always keep the correct blade depth
setting. The correct blade depth setting for
all cuts should not exceed 1/4 inch below
the material to be cut. Excess blade depth
will increase the chance of kickback and
cause the cut to be rough. One blade tooth
below the material to be cut works best for
efcient cutting action.
TO ADJUST BLADE DEPTH
1. Remove the battery pack from the saw.
2. Loosen the depth-of-cut adjustment lever.
3. Determine the desired depth of cut.
OPERATION
4. Hold the base of the saw at against the
edge of the workpiece and then raise or
lower the saw until the indicator mark
on the bracket aligns with the desired
depth-of-cut mark.
5. Tighten depth-of-cut adjustment
lever securely.

OPERATION
DANGER: When lifting the saw
from the workpiece, the blade is exposed
on the underside of the saw until the lower
blade guard closes. Make sure the lower
blade guard is closed before setting the
saw down.
WARNING: To make sawing easier
and safer, always maintain proper control
of the saw. Loss of control could cause an
accident resulting in possibly serious injury.
WARNING: Always clamp and
support the workpiece securely. Always
maintain proper control of the saw. Failure
to clamp and support the workpiece and
loss of control of the saw could result in
serious injury.
To make the best possible cut:
1. Hold the saw rmly with both hands.
2. Avoid placing your hand on the workpiece
while making a cut.
3. Support the workpiece so that the cut
(kerf) is always to your side.
4. Support the workpiece near the cut.
5. Clamp the workpiece securely so that the
workpiece will not move during the cut.
6. Always place the saw weight on the
portions of the workpiece that is
supported, not on the “cut off” piece.
7. Place the workpiece with the “good”
side down.
NOTICE: The good side of the workpiece is
the side where appearance is important.
8. Draw a guideline along the desired line of
cut before beginning your cut.
NOTICE: Do not touch the blade to the
workpiece until the saw has reached
maximum speed.
WARNING: If the blade comes
in contact with the workpiece before it
reaches full speed, it could cause the saw
to “kickback” towards you, which could
result in serious injury.
WARNING: ALWAYS clamp and
support workpiece securely. ALWAYS
maintain proper control of saw. Failure to
clamp and support workpiece and loss of
control of saw could result in serious injury.
INTEGRATED RIP AND
CROSSCUT RULERS
NOTICE: The distance from the line of cut
to the guideline is the amount you should
offset the guide.

Page 16
Marked along the base across the front of
the saw is a ruler for measuring repetitive
cuts. It is marked 1-1/2 inches to the left of
the 0° mark and 4-1/4 inches to the right of
45° mark in 1/16-inch increments.
When making a cross cut or rip cut, align
your line of cut with the left side of the notch
by the 00indicator. Since blade thicknesses
vary, always make a trial cut in scrap
material along a guideline to determine how
much, if any, the guideline must be offset to
produce an accurate cut.
NOTICE: Do not bind the blade in the cut. It
could cause the saw to “kickback” towards
you, which could result in serious injury.
WARNING: If the blade comes
in contact with the workpiece before it
reaches full speed, it could cause the saw
to “kickback” towards you, which could
result in serious injury.
MAKING RIP CUTS
The combination blade provided with your
saw is for both cross cuts and rip cuts.
Ripping is cutting lengthwise with the grain
of the wood (Fig.12).
When rip cutting large sheet, use a straight
edge (Fig.13).
1. Secure the workpiece.
2. Clamp a straight edge to the workpiece
using C-clamps.
3. Carefully guide the saw along the straight
edge to achieve a straight rip cut.
WARNING: ALWAYS clamp and
support workpiece securely. ALWAYS
maintain proper control of saw. Failure to
clamp and support workpiece and loss of
control of saw could result in serious injury.
BEVEL CUTTING
The angle of cut can be adjusted to any
desired setting between 0°and 50°.
NOTICE: When making 50° bevel cuts, the
blade should be set at full depth of cut.
Since blade thicknesses vary and different
angles require different settings, always
make a trial cut in scrap material along
a guideline to determine how much you
should offset the guideline on the workpiece
to be cut.

The chips and grindings from these materials
are highly abrasive to power tool parts, such
as bearings, brushes, commutators, etc.
Consequently, it is not recommended that
this tool be used for extended work on any
berglass material, wallboard, spackling
compound or plaster. During any use on
these materials, it is extremely important
that the tool is cleaned frequently by blowing
with an air jet.
