1. Keep the work area clean and well lighted. Cluttered benches and dark areas increase the risks of electric shock,  fire, and injury to persons.
2. Do not operate the tool in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. The tool is able to create sparks resulting in the ignition of the dust or fumes.
3. Keep bystanders, children, and visitors away while operating the tool. Distractions are able to result in the loss of control of the tool.

Personal Safety

1. Stay alert. Watch what you are doing and use common sense when operating the tool. Do not use the tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating the tool increases the risk of injury to persons.
2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair increases the risk of injury to persons as a result of being caught in moving parts.
3. Avoid unintentional starting. Be sure the switch is off before connecting to the air supply. Do not carry the tool with your finger on the switch or connect the tool to the air supply with the switch on.
4. Remove adjusting keys and wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool increases the risk of personal injury.
5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
6. Use safety equipment. A dust mask, non-skid safety shoes and a hard hat must be used for the applicable conditions.
7. Always wear eye protection. Wear ANSI-approved safety goggles.
8. Always wear hearing protection when using the tool. Prolonged exposure to high intensity noise is able to cause hearing loss.
9. Avoid body contact with grounded surfaces such as pipes, radiators, rangesand refrigerators. There is an increased risk of electric shock if your body is grounded.

Tool Use and Care

1. Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against the body is unstable and is able to lead to loss of control.
2. Do not force the tool. Use the correct tool for the application. The correct tool will do the job better and safer at the rate for which the tool is designed.
3. Do not use the tool if the switch does not turn the tool on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
4. Disconnect the tool from the air source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool unintentionally. Turn off and detach the air supply, safely discharge any residual air pressure, and release the throttle and/or turn the switch to its off position before leaving the work area.
5. Store the tool when it is idle out of reach of children and other untrained persons. A tool is dangerous in the hands of untrained users.
6. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that affects the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. There is a risk of bursting if the tool is damaged.
7. Use only accessories that are identified by the manufacturer for the specific tool model. Use of an accessory not intended for use with the specific tool model, increases the risk of injury to persons.

17. Avoid unintentional starting. Prepare to begin work before turning on the tool.

18. This product is not a toy. Keep it out of reach of children.

Kickback and Related Warnings

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 an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel 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. Abrasive wheels
may also break under these conditions.
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.

1. 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.
2. Never place your hand near the rotating accessory. Accessory may kickback over your hand.
3. 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.
4. 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.
5. Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

Safety Warnings Specific for Sanding Operations

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.

Vibration Precautions

This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury:

1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical check-ups to ensure medical problems
   are not being caused or worsened from use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, nervous system disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any symptoms related to vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible.

2. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury.

3. Wear suitable gloves to reduce the vibration effects on the user.

4. Use tools with the lowest vibration when there is a choice.

5. Include vibration-free periods each day of work.

6. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work.

7. To reduce vibration, maintain tool as explained in this manual. If abnormal vibration occurs, stop immediately.

Components and Controls

Initial Set Up

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.
Note: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram near the end of this manual.
Note: This air tool may be shipped with a protective plug covering the air inlet. Remove this plug before set up.

Air Supply Setup

WARNING
TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Use only clean, dry, regulated, compressed air to power this tool. Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool.

1. Incorporate a filter, regulator with pressure gauge, in-line shutoff valve, and quick coupler for best service, as shown in Figure A on page 10 and Figure B
   on page 11. An in-line shutoff ball valve is an important safety device because it controls the air supply even if the air hose is ruptured. The shutoff valve should be a ball valve because it can be closed quickly.
   Note: If an automatic oiler system is not used, add a few drops of Pneumatic Tool Oil to the airline connection before operation. Add a few more drops after each hour of continual use.

2. Attach an air hose to the compressor’s air outlet. Connect the
   air hose to the air inlet of the tool.
   Other components, such as a coupler plug and quick coupler, will make operation more efficient, but are not required.
   WARNING! TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
   Do not install a female quick coupler on the tool. Such a coupler contains an air valve that will allow the air tool to retain pressure and operate accidentally after the air supply is disconnected.
   Note: Air flow, and therefore tool performance, can be hindered by undersized air supply components.

3. Turn the tool’s throttle or switch to the off position; refer to Operation section for description of controls.

4. Close the in-line shutoff valve between the compressor and the tool.

5. Turn on the air compressor according to the manufacturer’s directions and allow it to build up pressure until it cycles off.

6. Adjust the air compressor’s output regulator so that the air output is enough to properly power the tool, but the output will not exceed the tool’s maximum air pressure at any time. Adjust the pressure gradually, while checking the air output gauge to set the right pressure range.

7. Inspect the air connections for leaks. Repair any leaks found.

8. If the tool will not be used at this time, turn off and detach the air supply and safely discharge any residual air pressure to prevent accidental operation.
   Note: Residual air pressure should not be present after the tool is disconnected from the air supply. However, it is a good safety measure to attempt to discharge the tool in a safe fashion after disconnecting to ensure that the tool is disconnected and unpowered.

Installing Backing Pad and Sanding Disc

The Sander features a locking spindle for toolless Backing Pad Installation, or the Backing Pad can be installed using the included 16 mm Wrench.

1. For toolless Backing Pad installation, rotate the Drive Spindle so the hole in the Spindle is lined up with the shaft on the Set Plate.

2. Push the Set Plate forward to insert the shaft on the Set Plate into the hole on the Drive Spindle, keeping it from freely turning while installing the Backing Pad.

3. Thread the Backing Pad securely into the Drive Spindle while holding the Spindle in place by hand, turning the Pad clockwise. Make sure the Backing Pad is attached tightly.

4. Once the Backing Pad is securely in place, push the Set Plate back to disengage the shaft on the Set Plate from the Drive Spindle, allowing the Drive Spindle to freely turn.
   Note: Ensure that the Set Plate is fully disengaged from the Drive Spindle prior to use. If the tool is operated with the Set Plate engaged with the Drive Spindle, the Sander will spin rather than randomly orbit.

5. Alternately, the Backing Pad can be installed using the supplied Wrench. Hold the Drive Spindle stationary with the Wrench and thread the Backing Pad securely into the Drive Spindle, turning the Pad clockwise.

6. The Sander ONLY uses 6″ diameter, PSA (Pressure Sensitive Adhesive) sanding discs (sold separately). Firmly attach the sanding disc to the Backing Pad.

Workpiece and Work Area Set Up

1. Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to prevent distraction and injury.

2. Route the air hose along a safe path to reach the work area without creating a tripping hazard or exposing the air hose to possible damage. The air hose must be long enough to reach the work area with
   enough extra length to allow free movement while working.

3. Secure loose workpieces using a vise or clamps (not included) to prevent movement while working.

4. There must not be hazardous objects (such as utility lines or foreign objects) nearby that will present a hazard while working.

General Operating Instructions

1. If an automatic oiler is not used, add a few drops of Pneumatic Tool Oil to the airline connection before use. Add a few drops more after each hour of continual use.

2. Wipe the work surface clean of all dirt and debris, especially that of previous courser sanding sessions, which will scratch the surface of a finer grit sanding session.

3. Attach the desired grit sanding disc (sold separately) onto the Backing Pad.

4. Attach the air supply.

5. Grip the Handle and depress the Trigger to start the tool. The speed of the Sander may be varied by turning the Speed Control. Allow the tool to reach the intended speed before sanding.
   CAUTION! Do not allow free, no-load rotating at high speed to avoid possible injury or damage to the tool.

6. Keep heavy pressure off of the Sander when operating. Allow the sanding disc to do the work.

7. Move the Sander in a uniform pattern up and down or side to side to ensure even sanding.
   Note: If the Sander creates swirls when it contacts the workpiece, disconnect the air supply and verify that the Set Plate is not engaging with the Drive Spindle.

8. Periodically, stop the Sander and check for possible disc wear. Replace used or worn sanding discs when necessary.

9. If the tool requires more force to accomplish the task, verify that the tool receives sufficient, unobstructed airflow (CFM) and increase the pressure (PSI) output of the regulator up to the maximum air pressure rating of this tool.
   CAUTION! TO PREVENT INJURY FROM TOOL OR ACCESSORY FAILURE:
   Do not exceed the tool’s maximum air pressure rating.
   If the tool still does not have sufficient force at maximum pressure and sufficient airflow, then a larger tool may be required.

10. To prevent accidents, after use, release the Trigger, detach the air supply and then safely discharge any residual air pressure in the tool. Clean external surfaces of the tool with a clean, dry cloth. Then store the tool indoors out of children’s reach.
