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 acci-
dents and injury.
MENTAL ALERTNESS REQUIRED. Full
mental alertness is required for safe oper-
ation 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, chang-
ing tooling, or servicing machine. This
prevents an injury risk from unintended
startup or contact with live electrical com-
ponents.
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 opera-
tion 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 con-
nect 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 cov-
ers reduce accidental contact with mov-
ing parts or flying debris. Ensure they
are properly installed, undamaged, and
working correctly.
CHILDREN & BYSTANDERS. Keep chil-
dren 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 service-
personnel 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 dis-
connecting 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 loca-
tions. 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 per-
forming the intended operation, stop
using the machine! Contact our Technical
Support at (570) 546-9663.

No list of safety guidelines can be
complete. Every shop environment
is different. Always consider safety
first, as it applies to your individual
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 ser-
viced.
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 obstruc-
tions. 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, caus-
ing serious injury. Replace dull blades
immediately.
TRIGGER LOCK. Make sure the trig-
ger lock is in the OFF position before
shutting the reciprocating saw OFF, or
before turning it ON.
Model T10874 (Mfd. Since 01/15)-4-
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 immo-
bile. 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 impor-
tant 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 sup-
ports 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 bind-
ing 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 motion-
less while the blade comes to a com-
plete 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 kick-
back.

SECTION 4: OPERATIONS
Blade Selection
Always use sharp blades and select the
correct saw blade for the material being
cut. The resulting cut will be cleaner and
more accurate, and there will be less stress
on the tool. This reciprocating saw can be
used to cut wood, metal or plastics depend-
ing upon the type of blade selected. Your
reciprocating saw comes with a wood and
metal blade, as listed in the Inventory.
A few points to remember in making
your blade selection:
• The overall blade length will affect the
thickness of material that can be cut.
Most reciprocating saw blades range in
length from 3" to 12".
• The width of the blade (measured from
the tip of one of the teeth to the back
edge of the blade) affects the durabil-
ity and resistance to bending during a
cut. A
7
⁄8" wide blade will be much more
durable than a
3
⁄8" wide blade.
• The number of teeth per inch (TPI)
affects the smoothness and speed of
the cut. A general purpose wood cut-
ting blade will usually have 4–14 TPI;
a metal cutting blade will have 14–24
TPI. Another factor is the tooth style
and how the teeth are set (the amount
the tooth is bent away from the plane of
the blade). Most blade manufacturers
provide guidelines on their packaging
for the types of materials and speeds to
use for a particular blade style. Review
their guidelines carefully before choos-
ing a blade for a particular project.
Fine-cut blades have high TPI and are
designed to produce a smooth cut. They
are generally used for cutting various
types of metal. They come in a variety of
lengths and widths (see Figure 5).
Rough-cut blades have low TPI and are
designed to make quick cuts. They are
generally used for cutting natural and man
made wood materials, drywall, or plastics.
These blades come in a variety of lengths
and widths (see Figure 6).

2. Rotate quick-release chuck counter-
clockwise and hold to disengage blade
lock.
3. Insert blade shank into chuck with teeth
pointed towards pivot joint on adjust-
able pivot foot (see Figure 7).
Note: Blade can be inserted upside
down; however, the setup outlined in
Step 3 is generally more stable and
safe.
1. DISCONNECT TOOL FROM POWER!
2. Rotate quick-release chuck counter-
clockwise and hold to disengage blade

Adjusting Pivot Foot Adjusting Rotating
Handle
To adjust rotating handle:
1. DISCONNECT TOOL FROM POWER!
2. Press and hold handle rotation button.
The pivot foot can be adjusted to allow
more or less clearance between the tip
of the blade and potential obstacles when
cutting in tight quarters. Extending the
foot effectively shortens the length of the
blade.
The handle rotation can be adjusted 180°
with five separate locking positions to
allow for a secure and comfortable grip—
no matter the cutting angle.
Failure to properly lock handle into
position could result in serious per-
sonal injury.
3. Rotate handle to desired position.
4. Release rotation button.
5. Gently twist handle until it locks into
position.

Failure to wear safety glasses while
operating the saw could cause seri-
ous personal eye injury.
Keep foot pressed firmly against
workpiece to reduce risk of kickback,
resulting in serious personal injury.
Starting saw with blade touching
workpiece could cause kickback
resulting in serious personal injury.
Operating Reciprocating Saw
Most operations performed with the Model
T10874 will produce the best results at
higher SPM (stroke per minute) settings;
however, slower SPM settings are ideal
when working with plastics that melt easily.
Use low-SPM settings when working
with plastics or other materials with
low melting points. Melted plastics
can liquefy, be thrown into the air,
and stick to the operator, causing
serious personal injury.
Low SPM's are best for cutting materi-
als that have low melting points, such as
plastics.
High SPM Uses
High SPM's are best for general cutting.
The blade removes material more quickly
at higher SPM's.

Pivot Foot
1. Install blade and adjust rotating handle.
2. Grasp tool firmly, then pull trigger allow-
ing saw to come up to desired speed.
3. Adjust speed by varying pressure
applied to trigger.
4. Rest pivot foot on workpiece, then ease
blade into workpiece (see Figure 10).
5. Maintain steady cut speed and pivot
foot pressure until cut is complete.
6. Wait for blade to completely stop
before setting tool down.
Model T10874 (Mfd. Since 01/15) -13-
Plunge Cutting
A plunge cut is a sawing operation in which
the cut is started above the workpiece; the
blade engages the workpiece surface by
"plunging" down through it, then advancing
the cut normally. We recommend avoiding
plunge cutting whenever possible due to
an increased risk of kickback or blade
breakage. Drilling a starter hole or using
a more appropriate tool should be used
instead.
2. Hold saw firmly and pull trigger, allow-
ing saw to come up to full speed, then
gradually lower blade tip into panel.
Allow blade to completely penetrate
panel before continuing cut.
3. After blade is through panel (see Figure
12) carefully position pivot foot flush
with workpiece, then finish cut.
Starting saw with blade touching
workpiece could cause kickback,
resulting in serious personal injury.
Plunge cuts should never be per-
formed on metal or hardwoods.
Tip: Depending on work to be performed,
blade can be installed upside down to aid
in plunge cutting.
To perform plunge cut:
1. Place bottom of pivot foot firmly on
workpiece and align tip of blade with
cut line (see Figure 11).
— If blade is installed upside down, use
opposite side of pivot foot.
Figure 11. Plunge cut blade placement.
Figure 12. Plunge cut foot placement.
Cutting Metal
When cutting metal, always begin at a
low SPM and slowly increase speed. This
will increase the accuracy of the cut and
prevent the blade from jumping around on
the surface of the workpiece. Using cut-
ting fluid will prolong blade life and prevent
over-heating.
To cut metal:
1. Install metal cutting blade.
2. Coat workpiece with cutting fluid.
3. Grasp tool firmly, then pull trigger,
allowing saw to come up to desired
speed.
4. Rest pivot foot on workpiece,
then ease blade into workpiece.
(see Figure 10 on Page 12).
5. Maintain steady cut speed and pivot
foot pressure until cut is complete.
6. Wait for blade to completely stop
before setting tool down.
