Read Operating Instructions Please become familiar with all the instructions and

warnings before operating any pneumatic tool. Always Wear Approved Eye Protection Impact resistant eye protection should meet or exceed the standards set forth in ANSI Z87.1, Occupational and Educational Eye and Face Protection. Look for marking

Z87.1 on your eye protection to ensure that it is an approved style. Hearing Protection is Recommended Hearing protection should be used when the noise level exposure equals or exceeds an 8 hour time-weighted

average sound level of 85dBA. Process noise, reflective surfaces, other tools being operated nearby, all add to the noise level in a given work area. If you are unable to determine your noise level exposure, we recommend the use of hearing protection.

Avoid Prolonged Exposure to Vibration Pneumatic tools can vibrate during use. Prolonged exposure to vibration or very repetitive hand and arm movements can cause injury. Discontinue the use of any tool if you experience tingling, numbness, discomfort or

pain in your hands or arms. You should consult your physician before resuming use of tool.

90 PSI Maximum This tool is designed to operate at an air pressure of 90

pounds per square inch gauge pressure (90 PSI) maximum, at the tool. Use of higher air pressure can, and

may cause injury. Also, the use of higher air pressure places the internal components under loads and stresses they were not designed for, causing premature

toot failure. NOTE: THEAIR SUPPLY SHOULD BE CLEAN, DRYAND

PREFERABLY LUBRICATED. FOR BEST RESULTS DRAIN THE MOISTURE FROM YOUR COMPRESSOR

DAILY.

CAUTION: Safety goggles should be worn when

operating the sander to avoid dust and particles from entering the eyes. Secure work with clamps or vise so

both hands are free to operate tool. Keep proper footing and balance at all times.

[ WARNIN I

Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemi- cals known 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, and

• arsenic and chromium from chemically- treated lumber.

Your risk from those 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, such as dust masks that are specifically designed to filter out microscopic par- ticles.

Recommended Operating Pressure ............ 60-90 PSI

Pre-Operation

Before the tool is connected to the air supply, clear the air hose of accumulated dust and moisture by running air

freely through the air hose for 5-10 seconds. Before

removing a toot for service, make sure the air line is shut-

off at the compressor. This will prevent the tool from operating if the throttle is accidentty engaged.

Installation (See figure 1)

This toot is designed to operate at 90 psi. Lower pres- sure (below 90 psi) will reduce performance of the toot while higher air pressure (over 90 psi) raises the perfor-

mance of the toot beyond its rated capacity and could

cause serious damage to tool and user. Always use clean dry air. Excessive moisture and dirt wilt

greatly reduce the life of any air motor. We recommend the installation of an in-line filter-regulator-lubricator as close to the toot as possible.

A 3/8" air hose is required up to a length of 8 ft. If more

length is required a 1/2" air hose should be used at the

compressor. Attach a 3/8" whip hose for the remaining 4 - 8 ft. for flexibility. Be sure all hoses and fittings are the

correct size and tightly secured before using air tool.

Air Tool

Use the pad lock to secure the oscillator when attaching and removing the pad.

NOTE: THIS TOOL IS NOT DESIGNED TO RUN WITH THE PAD LOCK IN PLACE. THE PAD LOCK IS TO BE USED ONLY WHEN ATTACHING AND REMOVING THE

PAD.

Let the sander do the work. The normal weight of the sander is sufficient for sanding. Do not put additional

pressure on the sander. This will only slow down the speed of the pad, reduce sanding efficiency and put an

additional burden on the motor. Start the sander off the work surface, set it down on the work surface evenly and

move it slowly back and forth in wide, overlapping areas. When finished sanding, lift it off the work surface before stopping motor.

Start the work with an abrasive grit just coarse enough to remove high spots and roughness. Follow with additional

sanding using finer grits until the desired finish is obtained. Never go from a coarse grit to a fine grit in one step. It may be difficult to remove swirl marks made by coarse abrasives. Use the finest grits practical for

roughing operations and finish by using successively finer grits.

Lubrication An in-line filter-regulator-lubricator (fig 1) is recommended

as it increases toot life and keeps the toot in sustained operation. The in-line lubricator should be regularly

checked and filled with air toot oil. Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the tools exhaust ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper.

Excessive amounts of oil should be avoided.

In the event that it becomes necessary to store the tool for an extended period of time (overnight, weekend, etc.), it should receive a generous amount of lubrication through

the air inlet. The tool should be run for approximately 30 seconds to ensure oil has been evenly distributed throughout the toot. The tool should be stored in a clean and dry environment.

Recommended lubricants: Use air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents and an EP (extreme pressure) additive.

Before the toot is connected to the air supply, clear the air hose of accumulated dust and moisture and add 1/4 oz.

of air tool oil.
