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 dan-

gerous 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.

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

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 replace-

ment parts. This will ensure that the safety of the power tool is maintained.

ADDITIONAL SPECIFIC SAFETY RULES

• Hold power tools by insulated gripping surfaces when performing an operation where the cut-

ting 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.

• Do not sand metal of any kind with your sander. Sparks may be generated by sanding screws,

nails or other metals which may ignite dust particles.

• Do not wet sand with this sander. Liquids may enter the motor housing and cause electric

shock.

• Empty dust collection system frequently, especially when sanding resin-coated surfaces

such as polyurethane, varnish, shellac, etc. Dispose of coated dust particles according to

the finish manufacturer’s guidelines, or place in a metal can with a tight fitting metal lid. Remove

coated dust particles from the premises daily. The accumulation of fine sanding dust particles

may self ignite and cause fire.

• 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.

• Sanding of lead-based paint, chemically pressure treated lumber or other materials that may

contain carcinogens is not recommended. Sanding of these materials should only be performed

by a professional.

• Clean out your tool often, especially after heavy use. Dust and grit containing metal particles

often accumulate on interior surfaces and could create a risk of serious injury, electric shock or elec-

trocution. ALWAYS disconnect the sander from the power source before cleaning. ALWAYS WEAR

SAFETY GLASSES that conform to ANSI Z87.1.

• ALWAYS disconnect tool from the power source before changing abrasive belts or sheets.

Such preventive safety measures reduce the risk of starting the power tool accidentally.

• Do not use PSA pads on random orbit sanders whose speed exceeds 12,000/min. The PSA

pad may rupture or fly apart during use causing serious personal injury to the user and bystanders.

EXTENSION CORD

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 number, the heavier the cord.

Some dust created by power sanding, sawing, grinding, drilling, and other construction activi-

ties 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 paint.

• crystalline silica from bricks and cement and other masonry products.

• arsenic and chromium from chemically-treated lumber (CCA).

Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To

reduce your exposure to these chemicals: work in a well ventilated area with approved safety equipment,

such as 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.

Use of this tool can generate and/or disburse dust, which may cause serious and perma-

nent respiratory damage or other injury. Always use NIOSH/OSHA/MSHA approved respiratory protection

appropriate for the dust exposure. Direct particles away from face and body.

ALWAYS wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) dur-

ing use. Under some conditions and duration of use, noise from this product may contribute to hearing

loss.

ALWAYS USE SAFETY GLASSES. (ANSI Z87.1) and (CAN/CSA Z94.3) Everyday eye-

glasses are NOT safety 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 S12.6 (S3.19) hearing protection

• NIOSH/OSHA/MSHA respiratory protection

ADDITIONAL SAFETY RULES FOR PAINT REMOVAL

1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the con-

taminated dust. The greatest danger of lead poisoning is to children and pregnant women.

2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis, we

recommend the following precautions when sanding any paint:

PERSONAL SAFETY

1. No children or pregnant women should enter the work area where the paint sanding is being

done until all clean up is completed.

2. A dust mask or respirator should be worn by all persons entering the work area. The filter should

be replaced daily or whenever the wearer has difficulty breathing. See your local hardware store

for the proper NIOSH approved dust mask.

3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingesting

contaminated paint particles. Workers should wash and clean up BEFORE eating, drinking or

smoking. Articles of food, drink, or smoking should not be left in the work area where dust would

settle on them.

ENVIRONMENTAL SAFETY

1. Paint should be removed in such a manner as to minimize the amount of dust generated.

2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mil thickness.

3. Sanding should be done in a manner to reduce tracking of paint dust outside the work area.

CLEANING AND DISPOSAL

1. All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the duration

of the sanding project. Vacuum filter bags should be changed frequently.

2. Plastic drop cloths should be gathered up and disposed of along with any dust chips or other

removal debris. They should be placed in sealed refuse receptacles and disposed of through

regular trash pick-up procedures. During clean up, children and pregnant women should be kept

away from the immediate work area.

3. All toys, washable furniture and utensils used by children should be washed thoroughly before

being used again.

MOTOR

Be sure your power supply agrees with nameplate marking. 120 Volts AC means your tool will operate on

alternating or direct current. As little as 10% lower voltage can cause loss of power and can result in over-

heating. All Porter Cable tools are factory-tested; if this tool does not operate, check the power supply.

Accessories must be rated for at least the speed recommended on the tool warning label.

Accessories running over rated speed can fly apart and cause injury. Accessory ratings must always be

above tool speed as shown on tool nameplate.

GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings and 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 reference

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. 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.

f) If operating a power tool in a damp location is unavoidable, use a ground fault circuit

interrupter (GFCI) protected supply. Use of a GFCI 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 connect-

ing to power source and/or battery pack, picking up or carrying the tool. Carrying power

tools with your finger on the switch or energising 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 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 jewellery. Keep your hair, clothing and

gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in mov-

ing 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
