2. electrical safety
a. power tool plugs must match the outlet.
ever 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.
b. 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.
c. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
d. 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.
e. 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.
f. 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.
3. personal safety
a. 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 influence of
drugs, alcohol or medication. A moment
of inattention while operating power tools
may result in serious personal injury.
b. use personal protective equipment. always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c. 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 finger
on the switch or energizing power tools that
have the switch on invites accidents.
d. 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.
e. Do not overreach. Keep proper
footing and balance at all times. This
enables better control of the power
tool in unexpected situations.
f. 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.
g. 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.
h. 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.
i. Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be
ANSI‑approved and breathing protection
must be NIOSH‑approved for the
specific hazards in the work area.
j. Do not lay the tool down until it has come to
a complete stop. Moving parts can grab the
surface and pull the tool out of your control.
k. When using a handheld power tool,
maintain a firm grip on the tool with
both hands to resist starting torque.
l. Do not depress the spindle lock when
starting or during operation.
m. Do not leave the tool unattended when the

interference or pacemaker failure.
p. The warnings, precautions, and instructions
discussed in this instruction manual cannot
cover all possible conditions and situations
that may occur. It must be understood by the
operator that common sense and caution are
factors which cannot be built into this product,
but must be supplied by the operator.
4. power tool use and care
a. 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.
b. Do not use the power tool if the switch

tool that cannot be controlled with the switch
is dangerous and must be repaired.
Page 4 For technical questions, please call 1-800-444-3353. Item 59556
SaFety OperatiOn MaintenanceSetup
c. 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.
d. 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.
e. 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.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g. use 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.
h. 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.
5. 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.
b. never service damaged Battery packs.
Service of BATTERY packs should
only be performed by the manufacturer
or authorized service providers.
c. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
6. cutting procedures
a. 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.
b. Do not reach underneath the workpiece.
The guard cannot protect you from
the blade below the workpiece.
c. 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.
d. never hold the workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform. It is important
to support the work properly to minimise body
exposure, blade binding, or loss of control.
e. Hold the 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
could give the operator an electric shock.
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 off-center, 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.
7. Kickback causes and related warnings
‑ Kickback is a sudden reaction to a pinched,
jammed 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 jammed
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.
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.
Page 5For technical questions, please call 1-800-444-3353.Item 59556
SaFetyOperatiOnMaintenance Setup
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 workpiece,
centre the saw blade in the kerf so that the
saw teeth are not engaged into the material.
If a saw blade binds, it may walk up or kickback
from the workpiece as the saw is restarted.
d. 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.
e. Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
f. Blade depth and bevel adjusting locking
levers must be tight and secure before
making the cut. If blade adjustment shifts while
cutting, it may cause binding and kickback.
g. use extra caution when sawing into existing
walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
8. Lower guard function
a. check the lower guard for proper closing
before each use. Do not operate the saw
if the lower guard does not move freely
and close instantly. never clamp or tie the
lower guard into the open position. If the
saw is accidentally dropped, the 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. the lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts”. raise the lower guard
by the retracting handle and as soon as the
blade enters the material, the lower guard
must be released. For all other sawing, the
lower guard should operate automatically.
d. always observe that the lower guard
is covering the blade before placing
the saw down on bench or floor. 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.
9. Battery tool use and care
a. prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to battery pack, picking up or carrying the
power tool. Carrying the power tool with your
finger on the switch or energizing power tool
that have the switch on invites accidents.
b. Disconnect the battery pack from the
power tool before making any adjustments,
changing accessories, or storing power
tool. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
c. 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.
d. use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
e. 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.
f. 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 burns.
g. Do not use a battery pack or power tool that
is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
h. Do not expose a battery pack or power
tool to fire or excessive temperature.
Exposure to fire or temperature above
140°F may cause explosion.
i. Follow all charging instructions and do
not charge the battery pack or power tool
outside of the temperature range specified
in the instructions. Charging improperly or at
temperatures outside of the specified range may
damage the battery and increase the risk of fire.
j. Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that
the safety of the product is maintained.

SaFety OperatiOn MaintenanceSetup
k. Do not modify or attempt to repair the power
tool or the battery pack except as indicated
in the instructions for use and care.
l. The battery Charger gets hot during
use. The Charger’s heat can build
up to unsafe levels and create a fire
hazard if it does not receive
adequate ventilation, due to an electrical fault, or
if it is used in a hot environment. Do not place
the Charger on a flammable surface. Do not
obstruct any vents on the Charger.
especially avoid placing the charger on
carpets and rugs; they are not only
flammable, but they also obstruct vents
under the charger. Place the Charger on a
stable, solid, nonflammable surface (such as a
stable metal workbench or concrete floor) at
least 1 foot away from all flammable objects,
such as drapes or walls. Keep a fire
extinguisher and a smoke detector in the area.
Frequently monitor the Charger and
Battery Pack while charging.
