Electrical safety (cont.)
5. When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use
6. If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply.
reduces the risk of electric shock.
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 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.
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.
2. Use safety equipment. Always wear eye
protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate
conditions will reduce personal injuries.
7. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
3. 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.
8. 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.
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.
Power tool use and care
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
safer at the rate for which it was designed.
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.
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.
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.
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.
7. Use the power tool, accessories and blades
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.
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.

Service
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.
Circular Saw Safety Warnings
•
If the blades become twisted or misaligned
in the cut, the teeth at the back edge of the
blades can dig into the top surface of the
wood causing the blades to climb out of the
kerf and jump back toward the operator.
1.
DANGER: Keep hands away from cutting
area and the blades. Keep your second hand on
auxiliary handle, or motor housing. If both hands
are holding the saw, they cannot be cut by the blades.
2. Do not reach underneath the workpiece.
The guard cannot protect you from the
blades below the workpiece.
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:
3. Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blades’
teeth should be visible below the workpiece.
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 blades, but not in line with the blades.
Kickback could cause the saw to jump backwards,
but kickback forces can be controlled by the
operator, if proper precautions are taken.
4. 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.
b. When blades are binding, or when interrupting
a cut for any reason, release the trigger
and hold the saw motionless in the material
until the blades come to a complete stop.
Never attempt to remove the saw from the
work or pull the saw backward while the
blades are in motion or kickback may occur.
Investigate and take corrective actions to
eliminate the cause of blade binding.
5. 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.
6. When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut
and reduces the chance of blade binding.
c. When restarting a saw in the workpiece,
center the saw blades in the kerf and
check that saw teeth are not engaged
into the material. If saw blades are binding,
they may walk up or kickback from the
workpiece as the saw is restarted.
7. 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.
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.
8. 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.
e. Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
9. Causes and Operator Prevention of Kickback:
•
Kickback is a sudden reaction to a pinched,
bound or misaligned saw blades, causing
an uncontrolled saw to lift up and out of
the workpiece toward the operator;
f. Blade depth and bevel adjusting locking levers
must be tight and secure before making cut.
If blade adjustment shifts while cutting,
•
When the blades are pinched or bound
tightly by the kerf closing down, the blades
stall and the motor reaction drives the
unit rapidly back toward the operator;
it may cause binding and kickback.
g. Use extra caution when making a
″plunge cut″ into existing walls or other
blind areas. The protruding blades may
cut objects that can cause kickback.

Circular Saw Safety Warnings (cont.)
10. 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
17. Do not use blades made from high-speed steel,
abrasive blades, metal-cutting blades or masonry-
cutting blades. The guards of this saw are not
designed to protect against the failure of such blades.
18. Place the larger portion of the saw base on
the larger, supported part of the workpiece.
This will help maintain balance and
moves freely and does not touch the blades or
any other part, in all angles and depths of cut.
control while the cut is completed.
19. Closely observe position of saw’s housing
during cut. Do not let housing bump
up against material being cut.
11. 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.
20. Blades must be rated to at least the maximum
speed marked on the tool. Use only blades
designed SPECIFICALLY for this saw.
12. 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 blades
enter the material, the lower guard must
be released. For all other sawing, the lower
guard should operate automatically.
21. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact Harbor
Freight Tools for a replacement.
22. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
13. Always observe that the lower guard is covering
the blades before placing saw down on bench
or floor. Unprotected, coasting blades will cause
the saw to walk backwards, cutting whatever
is in its path. Be aware of the time it takes for
the blades to stop after switch is released.
23. 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.
24. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.
14. DO NOT USE THIS SAW WITH THE
SAW HELD UPSIDE DOWN IN A VISE.
The saw is not designed for such use and
cannot be used safely in that position.
25. Do not leave the tool unattended when it is plugged
into an electrical outlet. Turn off the tool, and
unplug it from its electrical outlet before leaving.
15. Do not use to cut logs, tree
limbs, or uneven lumber.
26. Use clamps (not included) or other practical ways
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.
16. Wet lumber, green (unseasoned) lumber,
and pressure treated lumber all have
an increased potential for kickback and
should only be cut with blades for cutting
that lumber type. Wear a NIOSH-approved
respirator and have appropriate ventilation
whenever cutting pressure treated lumber.
27. This product is not a toy.
Keep it out of reach of children.
28. Verify that there are no utility lines or
hardware in or near the workpiece.
This is especially critical for plunge cuts.
29. Do not depress the spindle lock when
starting or during operation.

Circular Saw Safety Warnings (cont.)
30. WARNING: Handling the cord on this product will
expose you to lead, a chemical known to the State
of California to cause cancer, and birth defects or
other reproductive harm. Wash hands after handling.
(California Health & Safety Code § 25249.5, et seq.)
32. 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. In
addition, people with pacemakers should:
• Avoid operating alone.
31. WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities, contains chemicals known [to the State
of California] to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
• Do not use with power switch locked on.
• Properly maintain and inspect to avoid
electrical shock.
• Any power cord must be properly grounded.
Ground Fault Circuit Interrupter (GFCI)
should also be implemented – it prevents
sustained electrical shock.
• Lead from lead-based paints
• Crystalline silica from bricks and cement or other
masonry products
• Arsenic and chromium from
chemically treated lumber
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to filter out microscopic particles.
(California Health & Safety Code § 25249.5, et seq.)
33. 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.
Vibration Safety
This tool vibrates during use. Repeated or long-term
exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and
shoulders. To reduce the risk of vibration-related injury:
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Use tools with the lowest vibration
when there is a choice.
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-
ups to ensure medical problems are not being
caused or worsened from use. Pregnant women
or people who have impaired blood circulation
to the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
4. Include vibration-free periods each day of work.
5. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.

Grounding
TO PREVENT ELECTRIC SHOCK AND DEATH
FROM INCORRECT GROUNDING WIRE CONNECTION:
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded.
Do not modify the power cord plug provided with the tool. Do not use the tool if the power cord or
plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet,
have a proper outlet installed by a qualified electrician.
Double Insulated Tools: Tools with Two Prong Plugs
1. Tools marked “Double Insulated” do not
require grounding. They have a special
double insulation system which satisfies
OSHA requirements and complies with
the applicable standards of Underwriters
Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code.
2. Double insulated tools may be used in either of the
120 volt outlets shown in the preceding illustration.

Canada) to indicate it is acceptable for outdoor use.
2. As the distance from the supply outlet increases,
you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire
causes a serious drop in voltage, resulting in loss of
power and possible tool damage. (See Table A.)
7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualified electrician before using it.
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a 14 gauge cord can carry a higher current
than a 16 gauge cord. (See Table A.)
8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.

Using Lubrication Unit
1. The blades for the Double Cut Saw are
“dry cut” teeth. This mean the blades only
need to be lubricated in extreme cutting
situations, such as when cutting aluminum,
copper, stainless steel and cast iron.
2. To use Lubrication Unit, use cutter paste
that is in rod form which can be inserted
into the center of the Lubrication Unit.
3. Once paste rod is inserted, turn the
Lubrication Unit’s feeder wheel.
Work Piece and Work Area Set Up
1. Wooden work piece selection:
2. Designate a work area that is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
a. Work piece must be free of foreign
objects and loose knots.
b. Do not use to cut logs, tree limbs,
or uneven lumber.
3. Route the power cord along a safe route
to reach the work area without creating a
tripping hazard or exposing the power cord
to possible damage. The power cord must
reach the work area with enough extra length
to allow free movement while working.
c. Wet lumber, green (unseasoned) lumber,
and pressure treated lumber all have an
increased potential for kickback and should
only be cut with a blade designed for cutting
that lumber. Wear a NIOSH-approved
respirator and have appropriate ventilation
whenever cutting pressure treated lumber.
4. Secure loose workpieces using a vise or clamps
(not included) to prevent movement while working.
5. Verify that there are no utility lines or
hardware in or near the workpiece.
This is especially critical for plunge cuts.

3. Before starting a cut, draw a guideline
along the desired line of cut.
7. Cut using steady, even pressure.
Do NOT force the Saw. Forcing the saw
causes rough cuts and could shorten the
life of the saw or cause kickback.
4. Place the front edge of the saw blades on that
part of the workpiece that is solidly supported.
5. Do NOT place the saw on the part of the
workpiece that will fall off when the cut is made.
NOTE: THIS SAW WORKS BEST FOR SHORT CUTS.
For cuts longer than 6″, it is especially important
to follow the feed speed recommendations below,
and stop the cut or feed more slowly if the
motor starts slowing down during the cut or
if the blades start separating.
6. Slide the power switch forward to start the saw.
Let the blades reach full speed before beginning cut.
WARNING! Closely observe position of
saw’s housing during cut. Do not let housing
bump up against material being cut.
For materials thicker than 1/16″,
cuts longer than 6″ are not recommended.
8. Feed blade straight into the cut.
Feeding at an angle can damage the blade teeth.
9. To prevent accidents, turn off the tool and
disconnect its power supply after use. Clean, then
store the tool indoors out of children’s reach.
Feed Speed
Correct feed speed is determined by the hardness
and the thickness of the material being cut.
See following pages for how to cut certain cross sections.
2. If the feed speed is too fast:
a. The cut may split or splinter
the workpiece.
In thin materials, feed the blades down with the teeth
protruding. Then move forward (or backward) for cutting.
b. This will result in a poor cut with significant
discharge on the lower side of the material.
1. If the feed speed is too slow:
c. If feed speed is not slowed, the split will
grow bigger, potentially leading to
a. The blades will only press down the
material instead of cutting it.
serious injury and property damage.
b. The blade edges will glide and
wear down the material.
c. This will cause a poor cut and will cause
excessive wear on the blades.

period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly,
to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper
installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or consequential damages arising from the use of

return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
