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.
2. Use personal protective 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.
3. Prevent unintentional starting. Ensure the switch
is in the off-position before connecting the
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.
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
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
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.

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.
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 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 and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
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
SAFETYOPERATIONMAINTENANCESETUP
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 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.
4. 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.
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.
Drill Safety Warnings
1. Hold power tools by insulated gripping
surfaces when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a ″live″ wire will make exposed metal
parts of the tool ″live″ and shock the operator.
2. Let bit cool before touching, changing
or adjusting it. Bits heat up dramatically
while in use, and can burn you.
3. If the drill bit jams, release the trigger immediately;
drill torque can cause injury or break bit.
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 holding the saw, they cannot be cut by the blade.
2. Do not reach underneath the workpiece.
The guard cannot protect you from
the blade below the workpiece.
3. 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.
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.
5. Hold power tools 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 make exposed metal
parts of the 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.
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.
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.
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;
• 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;
• 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:
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 workpiece, center
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If
saw blade is binding, it may walk up or kickback
from the workpiece as the saw is restarted.
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 kerf 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.
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
moves freely and does not touch the blade or
any other part, in all angles and depths of 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.
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
blade enters the material, the lower guard
must be released. For all other sawing, the
lower guard should operate automatically.
13. 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 aware of the time it takes for
the blade to stop after switch is released.
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.
15. The torque developed during braking may
loosen the blade-retaining nut/bolt. The blade
retaining nut/bolt should be checked periodically
and tightened if necessary, especially after braking.
16. Do not use to cut logs, tree
limbs, or uneven lumber.
17. Wet lumber, green (unseasoned) lumber,
and pressure treated lumber all have an
increased potential for kickback and should
only be cut with a blade for cutting that
lumber type. Wear a NIOSH-approved
respirator and have appropriate ventilation
whenever cutting pressure treated lumber.
18. Do not use blades made from high-speed steel,
abrasive blades, or metal- or masonry-cutting
blades. The guards of this saw are not designed
to protect against the failure of such blades.
19. Place the larger portion of the saw base on the larger, supported part of the workpiece.
This will help maintain balance and
control while the cut is completed.
20. Do not depress the spindle lock when
starting or during operation.
