Warnings
_
ARNING! Read all safety warnings
and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL
WARNINGS
AND
INSTRUCTIONS
FOR FUTURE
REFERENC£
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, C/uttered 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) Power tool plugs must match the outlet. Never 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.
if operating a power tool in a damp location
is unavoidable,
use a ground
fault
circuit interrupter
(GFCI) protected
supply. Use of a GFC/ 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 too/may result in persona/injury.
e) Do not overreach. Keep proper
footing and balance at all times. This enables better
control of the power too/in unexpected situations.
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.
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
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 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 too/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. 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.
t) 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.
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 too/is maintained.
Additional
Specific
Safety
Rules
for Reciprocating
Saws
•
Hold power tool by insulated
gripping
surfaces
when performing
an operation
where
the cutting
accessory
may contact
hidden
wiring
or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of the too/ "live" and could give the
operator an electric shock
•
Use clamps or another practical
way to secure and support
the workpiece
to a stable
platform.
Holding the work by hand or against your body leaves it unstable and may lead to
loss of control.
•
Hold saw firmly with both hands for all cutting operations. During cutting operations, the
blade may suddenly bind in the work and may cause the saw to kickback towards the operator
•
Keep hands away from moving parts. Never place your hands near the cutting area.
•
Use extra caution
when cutting
overhead
and pay particular
attention
to overhead
wires which
may be hidden from view. Anticipate the path of falling branches and debris
ahead of time.
•
Do not operate
this tool for long periods
of time. Vibration caused by the operating action
of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide extra
cushion, take frequent rest periods, and limit daily time of use.
• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long
hair can be caught in moving parts.
• An extension
cord must have adequate
wire size (AWG or American
Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using more than one extension to make up
the total length, be sure each individual extension contains at least the minimum wire size. The
following table shows the correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The smaller the gauge numbed the heavier the
cord.

Not Recommended
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOTsafety glasses. Also use
face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT}
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
ANSI $12.6 ($3. 19) hearing protection,
• NIOSH/OSHA/MSHA
respiratory protection.
_WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of Califomia to cause canced birth
defects or other reproductive harm. Some examples of these chemicals are:
lead from lead-based paints,
crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically-treated lumber
Your risk from these exposures varies, depending on how often you do this type of work. Toreduce
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.
Avoid prolonged
contact with dust from power sanding,
sawing, grinding,
drilling, and
other construction
activities.
Wear protective
clothing
and wash exposed
areas with
soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.
_, WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and
permanent respiratory or other injury, Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.
_WARNING:
Always
wear proper
personal
hearing protection
that conforms
to ANSi
$12.6 ($3.19) during use. Under some conditions and duration of use, noise from this product
may contribute to hearing loss.
