Intended Use
The Ironton 8 ½ Inch Drywall Sander is designed to sand drywall or plaster walls and ceilings in any
position. The sander provides a superior finish and is faster than conventional methods for both new
construction and renovation work. Use the built-in extensions to change the length of the tool from 4ft.
to 5.6ft. long to reach up to 12ft. high. The sander is ergonomically designed for effortless handling. Its
removable brush segment allows sanding right up to the edge with ease. The robust drive system
transfers power efficiently to the sanding pad and ensures a long service life. The center and edge
vacuum locations provide a large area of dust collection. The tool hooks up easily to a standard
vacuum to ensure a dust-free working environment.

Important Safety Information
⚠WARNING
Read and understand all instructions. Failure to follow all instructions may result in serious injury
or property damage.
The warnings, cautions, and instructions in this manual cannot cover all possible conditions or
situations that could occur. Exercise common sense and caution when using this tool. Always be
aware of the environment and ensure that the tool is used in a safe and responsible manner.
Do not allow persons to operate or assemble the product until they have read this manual and
have developed a thorough understanding of how it works.
Do not modify this sander in any way. Unauthorized modification may impair the function and/or
safety and could affect the life of the product. There are specific applications for which the product
was designed.
Use the right tool for the job. DO NOT attempt to force small equipment to do the work of larger
industrial equipment. There are certain applications for which this equipment was designed. This
product will be safer and do a better job at the capacity for which it was intended. DO NOT use
this equipment for a purpose for which it was not intended.
Industrial or commercial applications must follow OSHA requirements.
⚠WARNING
WORK AREA SAFETY
Inspect the work area before each use. Keep work area clean, dry, free of clutter, and well-lit.
Cluttered, wet, or dark work areas can result in injury. Using the product in confined work areas
may put you dangerously close to cutting tools and rotating parts.

Page 5 of 19
Do not use the sander where there is a risk of causing a fire or an explosion; e.g., in the presence
of flammable liquids, gases, or dust. The product can create sparks, which may ignite the
flammable liquids, gases, or dust.
Do not allow the sander to come into contact with an electrical source. The tool is not insulated
and contact will cause electrical shock.
Keep children and bystanders away from the work area while operating the tool. Do not allow
children to handle the product.
Be aware of all power lines, electrical circuits, water pipes, and other mechanical hazards in your
work area. Some of these hazards may be hidden from your view and may cause personal injury
and/or property damage if contacted.
⚠WARNING
PERSONAL SAFETY
Stay alert, watch what you are doing, and use common sense when operating the tool. Do not use
the tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of
inattention while operating the tool may result in serious personal injury.
Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving
parts. Air vents on the tool often cover moving parts and should be avoided.
Wear the proper personal protective equipment when necessary. Use ANSI Z87.1 compliant safety
goggles (not safety glasses) with side shields, or when needed, a face shield. Use a dust mask in
dusty work conditions. Also use non-skid safety shoes, hardhat, gloves, dust collection systems,
and hearing protection when appropriate. This applies to all persons in the work area.
Do not overreach. Keep proper footing and balance at all times.
Remove keys or wrenches before connecting the tool to an air supply, power supply, or turning on
the tool. A wrench or key that is left attached to a rotating part of the tool may cause personal
injury.
Secure the work with clamps or a vise instead of your hand when practical. This safety precaution
allows for proper tool operation using both hands.
⚠CAUTION
SANDER USE AND CARE
Do not force the sander. Products are safer and do a better job when used in the manner for which
they are designed. Plan your work, and use the correct product for the job.
Check for damaged parts before each use. Carefully check that the product will operate properly
and perform its intended function. Replace damaged or worn parts immediately. Never operate the
product with a damaged part.
Do not use a product with a malfunctioning switch. Any power tool that cannot be controlled with
the power switch is dangerous and must be repaired by an authorized service representative
before using.

Page 6 of 19
Disconnect the power/air supply from the product and place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
Store the sander when it is not in use. Store it in a dry, secure place out of the reach of children.
Inspect the tool for good working condition prior to storage and before re-use.
Use only accessories that are recommended by the manufacturer for use with your product.
Accessories that may be suitable for one product may create a risk of injury when used with
another tool. Never use an accessory that has a lower operating speed or operating pressure than
the tool itself.
Keep guards in place and in working order. Never operate the product without the guards in place.
Do not leave the sander running unattended.
Specific Operation Warnings
⚠WARNING
To reduce the risk of injury, user must read instruction manual.
To reduce the risk of injury, always wear eye and respiratory protection.
Hold power tools by insulated gripping surfaces, when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Do not point the tool at people or animals.
Never place your hand near the rotating accessory. Accessories may kickback over your hand.
Grounding
⚠WARNING
This machine must be grounded while in use to protect the operator from electrical shock. This
unit is equipped with an electrical cord that has an equipment grounding conductor and a
grounding plug. The plug MUST be plugged into a matching receptacle that is properly installed
and grounded in accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PROVIDED PLUG. If it will not fit the receptacle, have the proper
receptacle installed by a qualified electrician.
CHECK with a qualified electrician or service person if you do not completely understand the
grounding instructions, or if you are not sure the tool is properly grounded.
Grounded Tools: Tools with 3-Prong Plugs
Tools marked with Grounding Required have a 3-wire cord and 3-prong grounding plug. The plug
must be connected to a properly grounded outlet. If the tool should electrically malfunction or break
down, grounding provides a low resistance path to carry electricity away from the user, reducing the
risk of electric shock. (See Figure A.)

Page 7 of 19
The grounding prong in the plug is connected through the green wire inside the cord to the grounding
system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding
system and must never be attached to an electrically live terminal.
Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance
with all codes and ordinances. The plug and outlet should look like those in the following illustration.
Double Insulated Tools: Tools with Two-Prong Plugs
Tools marked Double Insulated do not require grounding. They have a special double insulation
system which satisfies OSHA requirements and complies with the applicable standards of
Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code.
(See Figure B.)
Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration.
Extension Cords
⚠WARNING
USE A PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and cause
overheating.
Be sure your extension cord is properly wired and in good condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it. Protect your extension
cords from sharp objects, excessive heat and damp or wet areas.
Grounded tools require a 3-wire extension cord. Double Insulated tools can use either a 2- or 3-
wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in
loss of power and possible tool damage.
The smaller the wire’s gauge number, the greater the capacity of the cord. For example, a 14-
gauge cord can carry a higher current than a 16-gauge cord. Minimum extension cord wire size is
shown in the following table:

NOT RECOMMENDED
When using more than one extension cord to make up the total length, make sure each cord
contains at least the minimum wire size required.
If you are using one extension cord for more than one tool, add the nameplate amperes and use
the sum to determine the required minimum cord size.
If you are using an extension cord outdoors, make sure it is marked with the suffix W-A (Win
Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition. Always replace
a damaged extension cord or have it repaired by a qualified electrician before using it.
Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.
