IMPORTANT SAFETY INFORMATION
GENERAL POWER TOOL SAFETY WARNINGS
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below 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.
1. Work area safety
a. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b. 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.
c. Keep children and bystanders away
while operating a power tool. Distractions
can cause you to lose control.
2. Electrical safety
a. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase 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
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.
n. This product is not a toy.
Keep it out of reach of children.
o. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker 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.
Page 3For technical questions, please call 1-800-444-3353.Item 59641
b. 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.
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 4 For technical questions, please call 1-800-444-3353. Item 59641
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.
Page 5For technical questions, please call 1-800-444-3353.Item 59641
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.

5-YEAR LIMITED WARRANTY
This Hercules tool is warranted to the original purchaser to be free from defects in materials and workmanship
for a period of five (5) years beginning on the date of purchase. This warranty does not cover battery packs and
battery chargers, which are covered under separate warranties. To obtain warranty service, visit your local Harbor
Freight retail store. Warranty registration is not required. The product or part must be returned to us with proof of
purchase (e.g. in‑store receipt or packing slip/invoice) and may require shipment by purchaser to a service center
at purchaser’s expense. If our inspection verifies a covered defect in materials or workmanship during the warranty
period, we will, at our option, repair or replace the defective product. We will return repaired products within a
reasonable time at our expense, but if we determine that there is no defect, or that the defect resulted from causes
not within the scope of our warranty, then we will return the product to you if you pay return shipping costs.
This warranty does not cover any failure or damage that we determine is due directly or indirectly to normal
wear and tear, misuse, use not for the intended purpose or not in accordance with the product manual,
abuse, accident, rental, modification or alteration, unauthorized repair, improper installation, neglect, lack of
maintenance, or any other failure not arising from defective materials or workmanship. Fraudulent returns or
claims will be denied. The repair or replacement described in this warranty shall be your sole and exclusive
remedy. THIS WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS WARRANTIES, WRITTEN
OR ORAL, AND ANY IMPLIED WARRANTIES ARE DISCLAIMED TO THE EXTENT PERMITTED BY LAW
AND OTHERWISE LIMITED TO THE DURATION OF THE EXPRESS WARRANTY HEREIN. HARBOR
FREIGHT SHALL NOT BE LIABLE UNDER ANY CIRCUMSTANCES FOR ANY INCIDENTAL, INDIRECT,
SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES OR COSTS ARISING FROM THIS WARRANTY
OR THE USE OF THIS PRODUCT. SOME STATES DO NOT ALLOW LIMITATIONS ON HOW LONG AN
IMPLIED WARRANTY LASTS OR THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL
DAMAGES, SO THESE LIMITATIONS MAY NOT APPLY TO YOU. THIS WARRANTY GIVES YOU SPECIFIC
LEGAL RIGHTS, AND YOU MAY ALSO HAVE OTHER RIGHTS WHICH VARY FROM STATE TO STATE.
