WARNING: the risk of injury, read the instruction manual.

GENERAL POWER TOOL SAFETY WARNINGS

WARNING:

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 WARNING 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 connecting to power source and/or battery pack, picking up or

GENERAL SAFETY RULES continued

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

ADDITIONAL SPECIFIC SAFETY RULES

SAFETY WARNINGS COMMON FOR GRINDING, SANDING, WIRE BRUSHING, POLISHING OR ABRASIVE CUTTING-OFF OPERATIONS:

a) This power tool is intended to function as a sander. Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
b) Operations such as polishing, grinding, wire brushing or cutting-off are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
c) Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
d) The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their RATED SPEED can break and fly apart.
e) The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
f) The arbor size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the power tool. Accessories with arbor holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
g) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
i) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
j) Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and shock the operator.
k) Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
I) Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
m) Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
n) Regularly clean the power tool's air vents. The motor's fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
o) Do not operate the power tool near flammable materials. Sparks could ignite these materials.

p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory's rotation at the point of the binding.

For example, if a backing pad is snagged or pinched by the workpiece, the edge of the pad that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel's movement at the point of pinching.

Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory. Accessory may kickback over your hand.
c) Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel's movement at the point of snagging.
d) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

SAFETY WARNINGSPRECIFICFOR SANDINGOPERATIONS:

a) Do not use excessively oversized sanding disc paper. Follow manufacturer's recommendations when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback.

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.

ADDITIONAL SAFETY RULES FOR PAINT REMOVAL

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

Drywall Sander

Instruction Manual

FUNCTIONAL DESCRIPTION

FOREWORD

The PORTER-CABLE Drywall Sander is designed for sanding walls and ceilings made of drywall or plaster. The Sander provides a superior finish, and is faster than conventional finishing methods for both new construction and renovation work. Clean-up time for Model 7800 is minimized by the use of an external vacuum cleaner attached to the sander.

ASSEMBLY

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

ABRASIVE DISC SELECTION

An abrasive disc is already included with the Drywall Sander. For details on the type of grit, refer to the packaging. Higher grit number corresponds to a smoother finish.

CAUTION: Do not attempt to use any abrasives other than those recommended by PORTER-CABLE.

OPERATION

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before installing and removing accessories, before adjusting or changing set-ups or when making repairs. An accidental start-up can cause injury.

HOW TO HOLD A DRYWALL SANDER

Hold the sander with both hands on the main tube (A) Fig. 1. Position your hands anywhere along the main tube to provide the best combination of reach and leverage.

Porter-Cable 7800 - HOW TO HOLD A DRYWALL SANDER - 1

CAUTION: To reduce the risk of personal injury, keep your hands on the main tube (A) Fig. 1. Keep away from the sanding head area. The sanding head swivels in multiple directions and can pinch your hand.

CONNECTING THE SANDER TO YOUR SHOP VAC

Furnished with the Drywall Sander are:

  • A 13^ (396 cm) long vacuum hose. This hose has a standard 1-1/4" (3.2 cm) vacuum cleaner connector on one end and a special swivel connector on the other end. It has a static dissipating feature to dissipate static electrical charges.
  • An adapter [1-1/4" (3.2 cm) to 2-1/2" (6.4 cm)] to allow the connection of the sander to a 2-1/2" (6.4 cm) vacuum cleaner.

INSTALLATION

  1. Install the special drywall dust bag into your vacuum cleaner, following the instructions supplied with the vacuum cleaner. If this dust bag does not fit your vacuum cleaner correctly, purchase and install a suitable filter bag that is rated for drywall dust.

WARNING: To reduce the risk of personal injury, use a dust bag rated for drywall dust. Failure to do so will increase the level of airborne dust particles in the work area. Continued and prolonged exposure to high concentrations of airborne dust may affect your respiratory system function.

  1. Connect the vacuum hose to the Drywall Sander. Open the hose connector by turning the large nut (A) Fig. 2 counterclockwise a few turns. Push the vacuum hose swivel connector (B) Fig. 2 into the connector and seat firmly. Turn the large nut clockwise to tighten the connector.

Porter-Cable 7800 - INSTALLATION - 1

  1. Connect the vacuum hose to your vacuum cleaner. Use the 1-1/4" (3.2 cm) to 2-1/2" (6.4 cm) adapter if necessary. If your vacuum cleaner requires a special connector (something other than the standard 1-1/4" (3.2 cm) to 2-1/2" (6.4 cm) connectors supplied with the Drywall Sander), contact your vacuum cleaner supplier for the proper adapter.

TO START AND STOP THE DRYWALL SANDER

Be certain that the power circuit voltage is the same as that shown on the specification plate of the tool, and that the switch is OFF (O). Connect the tool to the power circuit.

The Drywall Sander is equipped with a "rocker" type switch (A) Fig. 4. The top end of the switch button is labeled "O" (OFF), and the bottom end of the button is labeled "I" (ON). To start the sander, press the bottom end of the "I" switch. To stop the sander, press the top end of the "O" switch.

Porter-Cable 7800 - TO START AND STOP THE DRYWALL SANDER - 1

SPEED CONTROL

The 7800 Sander is equipped with a variable speed control. Adjust the speed by turning the control knob (B) Fig. 4. The control knob is numbered "1" through "5". The setting "1" is the slowest speed (approximately 1000 RPM) and "5" is the fastest speed (approximately 2,000 RPM).

Use the higher speed settings for fast stock removal. Use the lower speed setting to reduce removal rate for more precise control. The Model 7801 Drywall Sander has a constant speed of 2,000 RPM.

BRUSH-TYPE SKIRT

A brush-type skirt (A) Fig. 5 surrounds the abrasive pad on the Model 7800. This skirt serves two purposes:

It extends below the surface of the abrasive pad to prevent the abrasive from "gouging" the work.
It helps contain the drywall dust until the vacuum cleaner pulls it away.

Replace the skirt if it is damaged or if it is worn excessively. Replacement skirts are available from any PORTER-CABLE Service Center.

Since the Model 7801 requires no vacuum cleaner, the skirt is shorter, but still prevents "gouging".

Porter-Cable 7800 - BRUSH-TYPE SKIRT - 1

TO REPLACE A SKIRT

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before installing and removing accessories, before adjusting or changing set-ups or when making repairs. An accidental start-up can cause injury.

  1. Remove abrasive pad (see Abrasive Pad Replacement).
  2. Use phillips screwdriver to remove the six retaining screws (B) Fig. 5.
  3. Lift the skirt out of housing.
  4. Position the new skirt to the housing and install the six retaining screws.
  5. Replace the abrasive pad.

SANDING DRYWALL

The Drywall Sander has an articulating sanding head. The head can swivel in multiple directions, allowing the abrasive pad to conform to the work surface (Figs. 6, 7, and 8). This action enables you to sand the top, middle, and bottom of a wall or ceiling joint without changing position.

  1. Turn the vacuum cleaner switch ON (I). (Model 7800 only).

WARNING: To reduce the risk of personal injury, ALWAYS wear a respirator approved by NIOSH for "Dust and Mist".

  1. Turn Drywall Sander switch ON (I).
  2. Position the Drywall Sander lightly against the work surface. Apply just enough pressure to align the sanding head with the work surface.
  3. Apply additional pressure to engage the abrasive pad on the work surface. Move the sander in an overlapping pattern to smooth the drywall compound down to a "featheredge".

Porter-Cable 7800 - SANDING DRYWALL - 1

Apply ONLY enough pressure to keep the abrasive pad flat against the work.

Keep the sander in constant motion while the abrasive pad is in contact with the work surface. Use a steady, sweeping motion. Excessive pressure, stopping the sander on the work, or moving the sander erratically can cause unacceptable swirl marks and unevenness in the work surface.

Porter-Cable 7800 - SANDING DRYWALL - 3

NOTE: Do not allow rotating abrasive pad to contact sharp protrusions. Contact with protruding objects (nails, screws, electrical boxes, etc.), can severely damage the abrasive pad.

ABRASIVE PAD REPLACEMENT

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before installing and removing accessories, before adjusting or changing set-ups or when making repairs. An accidental start-up can cause injury.

  1. Grasp the abrasive pad and the sander housing to prevent pad rotation.
  2. Rotate the pad retaining nut (A) Fig. 9 counterclockwise and remove.
  3. Lift off the large metal washer (B) Fig. 9, and the abrasive pad (C) Fig. 9.

NOTE: When the abrasive pad (C) Fig. 9 is lifted from the sander, the abrasive back-up disc (A) Fig. 10 is exposed. Note that this back-up disc is also covered with an abrasive material, and is used ONLY to prevent "slippage" between the back-up disc and the foam-backed abrasive pad. It is NOT suitable for use as a sanding abrasive. DO NOT USE THE SANDER WITHOUT A PROPER ABRASIVE PAD.

  1. Position the new abrasive pad to the back-up disc, and center the hole of the disc on the hub (B) Fig. 10 of the back-up disc.
  2. Position the large metal washer (B) Fig. 9, and the retaining nut (A) Fig. 9, to the sander.
  3. Rotate the retaining nut clockwise to hand tighten (while holding the abrasive pad as described in step 1).
