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

⁄8" wide blade will be much more

durable than a

⁄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).

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.
