Some dust created by power sanding, sawing, grinding,

drilling, and other construction activities contains chemicals

known (to the State of California) to cause cancer, 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

• arsenic and chromium from chemically-treated lumber

Your risk from these exposures varies, depending on how often you do this

type of work. To reduce your exposure to these chemicals: work in a well

ventilated area, and work with approved safety equipment, always wear

NIOSH/OSHA approved, properly fitting face mask or respirator when using

such tools.

CALIFORNIA PROPOSITION 65

It is important for you to read and understand this manual. The

information it contains relates to protecting YOUR SAFETY and

PREVENTING PROBLEMS. The symbols below are used to help

you recognize this information.

SAFETY GUIDELINES - DEFINITIONS

indicates an imminently hazardous situation which, if not

avoided, will result in death or serious injury.

indicates a potentially hazardous situation which, if not

avoided,could result in death or serious injury.

indicates a potentially hazardous situation which, if not

avoided,may result in minor or moderate injury.

used without the safety alert symbol indicates potentially

hazardous situation which, if not avoided, may result in

property damage.

Read all instructions. Failure to follow all

instructions listed below may result in electric

shock, fire and/or serious injury. The term "power tool" in all

of the warnings listed below refers to your mains-operated

(corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) Work area safety

a) Keep work area clean and well lit. Cluttered 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.

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 safety 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.

c) Avoid accidental starting. Ensure the switch is in the off-position

before plugging in. Carrying power tools with your finger on the switch

or plugging in 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 tool

GENERAL SAFETY RULES

may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This

enables better control of the power tool in unexpected situations.

f) 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 these devices 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 before making any

adjustments, changing accessories, or storing power tools. Such

preventive safety measures reduce the risk of starting the power tool

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 tools operation. If damaged, have the power tool repaired

before use. Many accidents are caused by poorly maintained power

tools.

f) 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 and in the manner intended for the particular

type of power tool, 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 tool is maintained.

GENERAL SAFETY RULES continued

1. Hold power tool 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.

2. Use clamps or other practical way to secure and support the workpiece

to a stable platform. Holding the work by hand or against your body is

unstable and may lead to loss of control.

3. Keep blades sharp. Sharp blades will do the job better and safer.

4. Keep hands away from cutting area. When sawing never reach

underneath or behind the material being cut for any reason.

5. When you have finished a cut be careful not to come into contact with

the blade. Turn off the motor immediately.

6. Exercise extreme caution when blind cutting. Be certain

that there are no foreign objects such as electrical wire, conduit, plumbing

pipes, etc., that may come into contact with the blade.

7. Wear eye and hearing protection. Always use safety glasses. Everyday

eyeglasses are NOT safety glasses. USE CERTIFIED SAFETY EQUIPMENT.

Eye protection equipment should comply with ANSI Z87.1 standards.

Hearing equipment should comply with ANSI S3.19 standards.

8. Use of this tool can generate and disburse dust or

other airborne particles, including wood dust, crystalline silica dust

and asbestos dust. Direct particles away from face and body. Always

operate tool in well ventilated area and provide for proper dust removal.

Use dust collection system wherever possible. Exposure to the dust may

cause serious and permanent respiratory or other injury, including silicosis

(a serious lung disease), cancer, and death. Avoid breathing the dust, and

avoid prolonged contact with dust. Allowing dust to get into your mouth

or eyes, or lay on your skin may promote absorption of harmful material.

Always use properly fitting NIOSH/OSHA approved respiratory protection

appropriate for the dust exposure, and wash exposed areas with soap and

water.

EXTENSION CORD SELECTION

If an extension cord is used, make sure the conductor size is large enough to

prevent excessive voltage drop which will cause loss of power and possible

motor damage. A table of recommended extension cord sizes will be found in this

section. This table is based on limiting line voltage drop to 5 volts (10 volts for 230

volts) at 150% of rated amperes.

If an extension cord is to be used outdoors, it must be marked with the suffix W-A

or W following the cord type designation. For example – SJTW-A to indicate it is

acceptable for outdoor use.

MOTOR

Many Porter-Cable tools will operate on either D.C., or single phase 25 to 60

cycle A.C. current and voltage within plus or minus 5 percent of that shown on

the specification plate on the tool. Several models, however, are designed for A.C.

current only. Refer to the specification plate on your tool for proper voltage and

current rating.

Do not operate your tool on a current on which the voltage

is not within correct limits. Do not operate tools rated A.C.

only on D.C. current. To do so may seriously damage the tool.

FOREWORD

Model 548 Bayonet Saw is designed for cutting materials of the following

MAXIMUM thickness: Wood 21/2", Aluminum 3/4", Steel 1/4".

SELECTING THE BLADE

To obtain best results with your Porter-Cable bayonet saw, it is important that

you use the right blade for the job. You will not only get better performance,

but your blades will last longer and a smoother cut will result.

NOTE: This tool is shipped completely assembled. No assembly time or

tools are required.

INSTALLING THE BLADE

Disconnect the tool from the power source.

The blade screw and nut lock the blade in the holder. The nut has a recess

on one side and the blade screw has a shoulder that fits within this recess.

NOTE: To avoid pinching and breakage of the blade make sure the recess

in the nut faces the screw head and the shoulder on the screw projects

slightly into this recess before installing the blade. Insert the blade into

the blade holder and over the screw, see Fig. 1. Use the wrench furnished

with your saw and apply only enough torque to firmly hold the blade.

NOTE: Do not over tighten as damage to the screw or nut may result.

TO START AND STOP SAW

1. Make sure power circuit voltage is the same as shown on the

specification plate on the saw. Connect saw to power circuit.

2. Squeeze switch trigger (A) Fig. 2 to start motor. Release trigger to stop

motor. This saw has a variable speed switch, as the switch trigger is

squeezed, the speed of the saw blade increases.

3. Lock Button – A lock button (B) Fig. 2, is provided to keep the saw running at

the fastest speed without

holding the switch trigger

“ON”. To lock the switch

trigger on, squeeze the

trigger as far as it will

go and push in the lock

button and release trigger.

To unlock the lock button,

squeze trigger allowing the

lock button free to spring out,

and release.

ASSEMBLY

Fig. 1

OPERATION

Fig. 2

BASE INSERT

Two base inserts, like the one shown in Fig. 3, are available to reduce

splintering the top fibers of plywood

and other splinter-prone materials. One

insert has a short center slot for use with

tapered tooth blades up to 1/4" wide. The

other insert has a long center slot for

use with tapered tooth blades that are

3/8" wide. DO NOT USE BASE INSERTS

WITH ANY TYPE BLADES OTHER THAN

THOSE DESCRIBED. TO DO SO, MAY

RESULT IN BLADE BREAKAGE OR

DAMAGE TO THE SAW.

To install insert, remove saw blade from

Bayonet Saw and locate insert in the throat of the saw base with the slot

forward and the beveled side of the slot up. Install appropriate blade as

outlined in section INSTALLING THE BLADE with the blade body in the slot

of the insert. To unlock the lock button, squeeze trigger allowing lock button free

to spring out, and release.

When cutting plywood with the base insert installed in the saw, it is not necessary

for the good or finished side of the material to be down as would be the practice

with an ordinary jig saw. The small teeth of the blade and speed of the saw in

conjunction with the base insert will prevent splintering or chipping of the top

surface.

PLUNGE CUTTING

When cutting into a wall avoid contact with all exposed

metal on the tool to prevent electrical shock hazard

resulting from accidentally cutting into a live wire. HOLD SAW AS

ILLUSTRATED IN Fig. 4.

One of the distinctive

and important features of

the Porter-Cable bayonet

saw is the ability to start the

cut (in wood only) within an

area without making drilled

holes first. This is especially

important when making

cut-outs for electric outlets

in finished walls, openings

in cabinet tops for sinks

and openings for plumbing

fixtures.

First, measure the area

to be cut out and mark

it clearly with a pencil,

chalk or scriber. Choose a

convenient starting point and hold the bayonet saw over the point and inside the

line of waste. Tip the machine forward until the front edge of the base rests firmly

on the surface of the material with the tip of the blade clear of the work surface,

as shown in Fig. 4. Turn motor “ON” and slowly lower the back of the machine

allowing blade to bite into surface of work. Do not move the machine forward until

the base is fully seated on the surface of the work.
