must be NIOSH-approved for the specific
hazards in the work area.
4. Power tool use and care
a.do not force the power tool. use the
correct power tool for your applica-
tion. The correct power tool will do the
job better and safer at the rate for which
it was designed.
b.use safety equipment. always wear
eye protection. Safety equipment such
as a )dust mask, non-skid safety shoes,
hard hat, or hearing protection used for
appropriate conditions will reduce per-
sonal injuries.
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.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 ac-
cidents.
c.disconnect the plug from the power
source and/or the battery pack from
the power tool before making any ad-
justments, changing accessories, or
storing power tools. Such preventive
safety measures reduce the risk of start-
ing the power tool accidentally.
d.remove any adjusting key or wrench
before turning the power tool on. A
wrench or a key left attached to a rotat-
ing part of the power tool may result in
personal injury.
d.store idle power tools out of the reach
of children and do not allow per-
sons unfamiliar with the power tool
or these instructions to operate the
power tool. Power tools are dangerous
in the hands of untrained users.
e.do not overreach. keep proper foot-
ing and balance at all times. This
enables better control of the power tool
in unexpected situations.
e.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 main-
tained power tools.
f. dress properly. do not wear loose
clothing or jewelry. keep your hair,
clothing and gloves away from mov-
ing parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
g.if devices are provided for the con-
nection of dust extraction and col-
lection facilities, ensure these are
connected and properly used. Use of
these devices can reduce dust-related
hazards.
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.
h.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
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

circular saw safety warnings
1.
danger: keep hands away from
cutting area and the blade. keep your
second hand on auxiliary handle, or
motor housing. If both hands are hold-
ing the saw, they cannot be cut by the
blade.
5. battery tool use and care
a.recharge only with the charger speci-
fied 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. do not reach underneath the work-
piece. The guard cannot protect you
from the blade below the workpiece.
b.Use power tools only with specifically
designated battery packs. Use of any
other battery packs may create a risk of
injury and fire.
3. adjust the cutting depth to the thick-
ness of the workpiece. Less than a full
tooth of the blade teeth should be visible
below the workpiece.
c.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 termi-
nals together may cause burns or a fire.
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.
d.under abusive conditions, liquid may
be ejected from the battery; avoid
contact. if contact accidentally oc-
curs, flush with water. If liquid con-
tacts eyes, additionally seek medical
help. Liquid ejected from the battery may
cause irritation or burns.
5. Hold power tool by insulated gripping
surfaces when performing an opera-
tion where the cutting tool may con-
tact hidden wiring. Contact with a″ live″
wire will also make exposed metal parts
of the power tool ″ live″ and shock the
operator.
6. 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.
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.
7. always use blades with correct ar-
bor hole for the tool. Blades that do
not match the mounting hardware of the
saw will run eccentrically, causing loss of
control.
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 safe-

ty of operation. Observe thread direction
of the bolt.
rective actions to eliminate the cause of
blade binding.
c.when restarting a saw in the work-
piece, center the saw blade in the cut
and check that saw teeth are not en-
gaged into the material. If saw blade is
binding, it may walk up or kickback from
the workpiece as the saw is restarted.
9. causes and operator Prevention of
kickback:
• 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;
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.
• 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;
e.do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
• If the blade becomes twisted or mis-
aligned 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.
f. blade depth and bevel adjusting lock-
ing levers must be tight and secure
before making cut. If blade adjustment
shifts while cutting, it may cause binding
and kickback.
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:
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.
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.
10. check Lower guard (a7) on circular
saw 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.when blade is binding, or when inter-
rupting a cut for any reason, release
the trigger and hold the saw motion-
less 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 cor-
11. check the operation of the Lower
guard (a7) spring on the circular
saw. 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.
reciprocating saw safety warnings
1. Hold power tool by insulated gripping
surfaces when performing an opera-
tion where cutting tool may contact
hidden wiring or its own cord. Con-
tact with a ″live″ wire will make exposed
metal parts of the tool ″live″ and shock
the operator.
12. Lower guard (a7) on the circular saw
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.
2. use clamps or another practical way
to secure and support the work piece
to a stable platform. Holding the work
by hand or against your body leaves it
unstable and may lead to loss of control.
13. always observe that the Lower guard
(a7) on the circular saw is covering
the blade before placing saw down on
bench or floor. An unprotected, coasting
blade will cause the saw to walk back-
wards, cutting whatever is in its path. Be
aware of the time it takes for the blade to
stop after switch is released.
3. When using the Reciprocating Saw,
do not cut material that is thicker than
the Saw Blade is long. Allow for blade
stroke.
14. The circular saw is designed for use
only with a 5-1/2” diameter saw blade
having a 10mm arbor and rated to
4,000 rPM or greater. Do not use any
other rated blade.
15. To prevent serious injury from flying
shrapnel, do not use any abrasive
wheels on the circular saw. The saw
and its guards are not designed to ac-
commodate abrasive wheels.
drill safety warnings
1. Hold power tools by insulated grip-
ping surfaces when performing an
operation where the cutting tool may
contact hidden wiring or its own cord.
Contact with a ″live″ wire will make ex-
posed metal parts of the tool ″live″ and
shock the operator.

additional safety warnings
1. Maintain labels and nameplates on the
tool. These carry important safety infor-
mation. If unreadable or missing, con-
tact Harbor Freight Tools for a replace-
ment.
• Avoid operating alone.
2. Avoid unintentional starting. Prepare to
begin work before turning on the tool.
• Do not use with power switch locked
on.
3. 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.
• Properly maintain and inspect to avoid
electrical shock.
• Any power cord must be properly
grounded. Ground Fault Circuit Inter-
rupter (GFCI) should also be imple-
mented – it prevents sustained electri-
cal shock.
4. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.
5. Do not leave the Charger unattended
when it is plugged into an electrical
outlet. Unplug it from its electrical outlet
before leaving.
9. Some dust created by power sand-
ing, sawing, grinding, drilling, and other
construction activities, contains chemi-
cals known [to the State of California]
to cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:

during use. The charger’s
heat can build up to unsafe
levels and create a fire haz-
• Lead from lead-based paints
ard if it does not receive adequate venti-
lation, due to an electrical fault, or if it is
used in a hot environment.
• Crystalline silica from bricks and ce-
ment or other masonry products
• Arsenic and chromium from chemically
treated lumber
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 during use.
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 ventilat-
ed area, and work with approved safety
equipment, such as those dust masks
that are specially designed to filter out
microscopic particles. (California Health

7. NEVER cut into areas where you cannot
identify any possible hazards behind or
inside the surface being cut.
1. Choose the correct Saw Blade (B15/
B16) for the material being cut. Fine
tooth Saw Blades (B16) are generally
used for cutting metal. Saw Blades (B15)
with larger teeth are generally used for
cutting wood.
8. In preparation to making a cut, place the
Guard on the surface to be cut. Align the
Saw Blade with the direction of the cut
and slowly lower the saw blade onto the
cut line to begin the cut. Do not attempt
to cut with the tip of the blade; kickback
and damage to the blade could result.
Note: When cutting hard woods, a hole
should be drilled first to insert the saw
blade (see Plunge Cutting on next page).
2. To avoid accidental injury, make sure
to wear heavy duty work gloves when
installing the Saw Blade.
3. Open the Outer Ring of the Clutch by
turning it counterclockwise. Insert the
shank of the Saw Blade (B15/B16) fully
into the Chuck, making sure the teeth
of the Saw Blade face downward, away
from the tool. Then release the Outer
Ring and make sure it locks the Saw
Blade in place.
9. When finished cutting, release the Trig-
ger to stop the tool.
10. Remove the Battery Pack (1).
11. Clean, then store the Saw indoors and
out of children’s reach.

the screw driver bit in the head of the
screw or bolt and cause the screw or bolt
to thread into or unthread from the mate-
rial.
b. The numbered settings from 1 to 23 are
for driving screws, bolts and nuts.
• It is recommended that a very low
torque setting be used for the first
drive, and adjust the setting as the
proper force required is determined.
7. When drilling a hole, let the Drill/Driver
do the work, using only enough pressure
to follow the drill as it cuts the hole in the
material.
• The torque setting required depends
on the item being driven. In the case of
screws, consider the size, length, and
type of material.
8. When finished using the Drill/Driver, re-
lease the Trigger Switch (C4), and center
the Forward/Lock/Reverse Button (C10)
to lock the trigger mechanism as a safety
measure.
• If a pilot hole has been drilled into the
material, the torque setting required will
be less to drive the screw.
c. In addition to single or double-ended
screwdriver bits, adapters with hexago-
nal shafts with matching socket heads
can also be used.
9. Remove the Battery Pack (1).
10. Clean then store the Drill/Driver indoors
