NOTICE

Safety Instructions for Power Tools

OWNER’S MANUAL. Read and under-

stand this owner’s manual BEFORE using
machine.

TRAINED OPERATORS ONLY. Untrained
operators have a higher risk of being hurt
or killed. Only allow trained/supervised
people to use this power tool. When tool
is not being used, disconnect power, and
store in out-of-reach location to prevent
unauthorized use—especially around
children. Make workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not
use tools in areas that are wet, cluttered,
or have poor lighting. Operating tools in
these areas greatly increases risk of acci­dents and injury.

MENTAL ALERTNESS REQUIRED. Full
mental alertness is required for safe oper­ation of power tools. Never operate under
the influence of drugs or alcohol, when
tired, or when distracted.

DISCONNECT POWER FIRST. Always
disconnect tool from power supply
BEFORE making adjustments, chang­ing tooling, or servicing machine. This
prevents an injury risk from unintended
startup or contact with live electrical com­ponents.

EYE PROTECTION.

Always wear ANSI-

approved safety glasses or a face shield

when operating or observing machinery to

reduce the risk of eye injury or blindness
from flying particles. Everyday eyeglasses
are not approved safety glasses.

Model T10874 (Mfd. Since 01/15)-2-

ELECTRICAL SAFETY. Tool plug must
match outlet. Double-insulated tools have
a polarized plug (one blade is wider than
the other), which must be plugged into a
polarized outlet. Never modify plug. Do
not use adapter for grounded tools. Use
a ground fault circuit interrupter if opera­tion is unavoidable in damp locations.
Avoid touching grounded surfaces when
operating tool.

WEARING PROPER APPAREL. Do not
wear clothing, apparel or jewelry that
can become entangled in moving parts.
Always tie back or cover long hair. Wear
non-slip footwear to avoid accidental
slips, which could cause loss of workpiece
control. Wear hard hat as needed.

HAZARDOUS DUST. Dust created while
using tools may cause cancer, birth
defects, or long-term respiratory damage.
Be aware of dust hazards associated with
each workpiece material, always wear
a NIOSH-approved respirator, and con­nect tool to an appropriate dust collection
device to reduce your risk.

HEARING PROTECTION. Always wear
hearing protection when operating or
observing loud machinery. Extended
exposure to this noise without hearing
protection can cause permanent hearing
loss.

REMOVE ADJUSTING TOOLS. Never
leave adjustment tools, chuck keys,
wrenches, etc. in or on tool—especially
near moving parts. Verify removal before
starting!

INTENDED USAGE. Only use tool for its
intended purpose. Never modify or alter
tool for a purpose not intended by the
manufacturer or serious injury or death
may result!

AWKWARD POSITIONS. Keep proper
footing and balance at all times when
operating tool. Do not overreach! Avoid
awkward hand positions that make tool
control difficult or increase the risk of
accidental injury.

SAFE HANDLING. Firmly grip tool. To
avoid accidental firing, do not keep finger
on switch or trigger while carrying.

FORCING TOOLS. Use right tool for job,
and do not force it. It will do job safer and
better at rate for which it was designed.

SECURING WORKPIECE. When
required, use clamps or vises to secure
workpiece. This protects hands and frees
both of them to operate tool.

GUARDS & COVERS. Guards and cov­ers reduce accidental contact with mov­ing parts or flying debris. Ensure they
are properly installed, undamaged, and
working correctly.

CHILDREN & BYSTANDERS. Keep chil­dren and bystanders at a safe distance
from the work area. Stop using tool if they
become a distraction.

USE RECOMMENDED ACCESSORIES.
Consult this manual or manufacturer
for recommended accessories. Using
improper accessories will increase risk of
serious injury.

MAINTAIN WITH CARE. Keep cutting
tool edges sharp and clean. Follow all
maintenance instructions and lubrication
schedules to keep tool

in good work-

ing condition. A tool that is improperly
maintained could malfunction, leading to
serious personal injury or death. Only
have tool serviced by qualified service­personnel using matching replacement
parts.

CHECK DAMAGED PARTS. Regularly
inspect tool for any condition that may
affect safe operation. Immediately repair
or replace damaged or mis-adjusted parts
before operating tool.

MAINTAIN POWER CORDS. When dis­connecting cord-connected tools from
power, grab and pull the plug—NOT the
cord. Carrying or pulling the cord may
damage wires inside. Do not handle cord/
plug with wet hands. Avoid cord damage
by keeping it away from heated surfaces,
high traffic areas, harsh chemicals, sharp
edges, moving parts, and wet/damp loca­tions. Damaged cords increase risk of
electrocution.

UNATTENDED OPERATION. Never
leave tool running while unattended. Turn
tool OFF and ensure all moving parts
completely stop before walking away.

EXPERIENCING DIFFICULTIES.

If at

any time you experience difficulties per­forming the intended operation, stop
using the machine! Contact our Technical
Support at [phone].

working conditions. Use this and
other machinery with caution and
respect. Failure to do so could result
in serious personal injury, damage to
equipment or poor work results.

Additional Safety Instructions for

Reciprocating Saws

SAFE WORK ENVIRONMENT. Clear

the work area of all parts and debris that
may cause injury by flying objects.

SECURING WORKPIECE. Secure
workpiece in a vise or work holding
device. Do not attempt to hold the
workpiece by hand.

OVERLOADING SAW. Do not apply
excessive pressure to the tool while
in use. If the speed drops abnormally,
decrease pressure immediately.

TOOL INSPECTION. Run the tool free
of the workpiece before using to ensure
all parts are running smooth and there
are no abnormal sounds or sparks. If
any defect is found, have the unit ser­viced.

REMOVING BLADES. Wear gloves to
protect your hands when removing the
blade to avoid injury.

CHECKING WORKSITE. Make sure
the workpiece is not supporting another
structure and that there are no obstruc­tions. Before cutting into walls, check
for wires, other electrical hazards, or
plumbing which may be hidden in the
wall space.

SECURING BLADE. Make sure the
blade locking screw is secured before
operating the reciprocating saw so the
blade does not loosen or fly out, which
could cause serious injury.

KEEP BLADES SHARP. Do not use dull
or damaged blades. They may break
or cause the workpiece to be expelled
toward the operator at high speed, caus­ing serious injury. Replace dull blades
immediately.

TRIGGER LOCK. Make sure the trig­ger lock is in the OFF position before
shutting the reciprocating saw OFF, or
before turning it ON.

Understanding

Kickback

Preventing Kickback

Kickback is a sudden and unexpected
expulsion of the saw from the workpiece,
which can violently propel the saw back
toward the operator, resulting in accidental
blade contact or impact injury.

Kickback is caused when the saw blade
becomes misaligned, pinched, bound, or
comes in contact with a material it is
unable to cut. When kickback occurs, the
saw blade becomes immediately immo­bile. The force produced by the motor is
diverted from the blade and transferred
to the saw, pushing it up and away from
the workpiece and potentially toward the
operator.

The lack of warning and high risk of injury
from kickback makes it extremely impor­tant to: (1) reduce the risk of kickback, and
(2) protect yourself in case it does occur.

Take these precautions to help prevent
the most common causes of kickback:

• Hold saw firmly with both hands and
position arms to help resist kickback
forces. Always stand to one side of saw
when operating—never directly behind
it. When kickback does occur, it will
eject the saw back toward the operator.

• Support large panels, making sure sup­ports are positioned under both sides of
the cutting line.

• Allow blade to reach full speed before
starting the cut.

• To help prevent the blade from bind­ing in the workpiece: (1) keep cuts
straight, (2) maintain a consistent depth
and angle throughout cut, (3) provide
proper workpiece support on both sides
of the cut.

• Follow cuts through to completion
whenever possible. If a cut must be
stopped before completion or the
blade begins to bind, release the ON/
OFF trigger and hold the saw motion­less while the blade comes to a com­plete stop before removing it from
the workpiece. When resuming the
cut, center your blade in the kerf and
ensure that the teeth are not touching
the workpiece.

• Only use sharp, clean, undamaged
blades. Dull blades create much more
friction and resistance while cutting,
which greatly increases the risk of kick­back.
