OPERATING INSTRUCTIONS

Warning: Always wear eye protection. Operator of tool is responsible for following: accepted eye, face, respiratory, hearing and body protection. Caution: Hand, wrist and arm injury may result from repetitive work, motion and overexposure to vibration.

• Keep hand and clothing away from working end of the air tool.

Operation: Be sure that any loose clothing, hair and all jewelry is properly restrained.

• Secure inlet bushing on air tool with a wrench before attempting to install the air fitting to avoid damaging housing assembly.

• BEFORE MOUNTING AN ACCESSORY, after all tool repairs and whenever a 3" x 24" Belt Sander is issued for use, check tool RPM (speed) with tachometer with air pressure set at 90 PSIG while the tool is running. If tool is operating at a higher speed than the RPM marked on the tool housing, or operating improperly, the tool must be serviced and corrected before use.

Caution:Tool RPM must never exceed abrasive/accessory RPM rating. Check accessory manufacturer for details on maximum operating speed or special

mounting instructions.

• With power source connected at the air tool relieve hose of air pressure and disconnect tool from air supply when changing recommended accessories.

• Connect air tool to power source. Be careful NOT to depress throttle lever in the process.

Do not expose air tool to inlet pressure above 90 PSIG or (6.2 Bars).

Caution:After installing the accessory, before testing or use and/or after reassembling tool, the 3" x 24" Belt Sander must be started at a reduced

speed to check for good balance. Gradually increase tool speed. DO NOT USE if tool vibration is excessive. Correct cause, and retest to insure safe operation.

• Only use abrasive sanding belts when properly secured to the drive and idler wheels of the air sander.

• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris. Potentially explosive atmospheres can be caused by dust and fumes resulting from sanding or grinding. Always use dust extraction or suppression systems which are suitable for the material being processed.

• Proceed with caution in unfamiliar surroundings. Hidden hazards may exist, such as electricity or other utility lines.

• Air tools are not intended for use in explosive atmospheres and are not insulated for contact with electric power sources.

• Use a vise or clamping device to hold work piece firmly in place.

• Work may generate hazardous dust.

• Do not apply excessive force on tool or apply “rough” treatment to it.

• Always work with a firm footing, posture and proper lighting.

Maintenance Instructions

Important: Apreventative maintenance program is recommended whenever portable power tools are used. The program should include inspection of air supply lines, air line pressure, proper lubrication and repair of tools. Refer to ANSI B186.1 for additional maintenance information.

• Use only genuine Dynabrade replacement parts to insure quality. To order replacement parts, specify Model#, Serial# and RPM of your air tool.

• It is strongly recommended that all Dynabrade rotary vane air tools be used with a Filter-Regulator-Lubricator to minimize the possibility of misuse due

to unclean air, wet air or insufficient lubrication. Dynabrade recommends the following: 11405 Air Filter-Regulator-Lubricator (FRL) – Provides accurate air pressure regulation and two stage filtration of water contaminants. Operates 40 SCFM @ 100 PSIG with 3/8" NPT female ports.

• Apply 3 plunges of 95542 Grease through grease fitting located on side of angle head with 95541 Grease Gun after every 100 Hours of use.

• Dynabrade recommends one drop of air lube per minute for each 20 SCFM (example: if the tool specification states 40 SCFM, set the drip rate on the

filter-lubricator to 2 drops per minute). Dynabrade Air Lube (P/N 95842: 1 pt 473 ml) is recommended.

Routine Preventative Maintenance:

• Check the free speed of 3" x 24" Belt Sander by using a tachometer on regular basis.

• Mineral spirits are recommended when cleaning the tool and parts. Do not clean tool or parts with any solvents or oils containing acids, esters,

ketones, chlorinated hydrocarbons or nitro carbons.

• DO NOT

clean or maintain tools with chemicals that have a low flash point (example: WD-40®).

• A Motor Tune-Up Kit (P/N 98223) is available which includes high wear and medium wear motor parts.

• Air tool labels must be kept legible at all times, if not, reorder label(s) and replace. User is responsible for maintaining specification information i.e.:

Model #, S/N, and RPM. (See Assembly Breakdown)

• Blow air supply hose out prior to initial use.

• Visually inspect air hoses and fittings for frays, visible damage and signs of deterioration. Replace damaged or worn components.

• Refer to Dynabrade's Warning/Safety Operating Instructions Tag (Reorder No. 95903) for safety information.

After maintenance is performed on tool, add a few drops of Dynabrade Air Lube (P/N 95842) to the air line and start the tool a few times to lubricate air motor. Check for excessive tool vibration.

Handling and Storage:

• Use of tool rests, hangers and/or balancers is recommended.

• Protect tool inlet from debris (see Notice below).

• DO

NOT carry tool by air hose, or near the tool throttle lever.

• Protect abrasive accessories from exposure to water, solvents, high humidity, freezing temperature and extreme temperature changes.

• Store accessories in protective racks or compartments to prevent damage.

Notice

All Dynabrade motors use the highest quality parts and materials available and are machined to exacting tolerances. The failure of quality pneumatic motors can most often be traced to an unclean air supply or the lack of lubrication. Air pressure easily forces dirt or water contained in the air supply into motor bearings causing early failure. It often scores the cylinder walls and the rotor blades resulting in limited efficiency and power. Our warranty obligation is contingent upon proper use of our tools and cannot apply to equipment which has been subjected to misuse such as unclean air, wet air or a lack of lubrication during the use of this tool.

One Y ear Warranty

Following the reasonable assumption that any inherent defect which might prevail in a product will become apparent to the user within one year from the date of purchase, all equipment of our manufacture is warranted against defects in workmanship and materials under normal use and service. We shall repair or replace at our factory, any equipment or part thereof which shall, within one year after delivery to the original purchaser, indicate upon our examination to have been defective. Our obligation is contingent upon proper use of Dynabrade tools in accordance with factory recommendations, instructions and safety practices. It shall not apply to equipment which has been subject to misuse, negligence, accident or tampering in any way so as to affect its normal performance. Normally wearable parts such as bearings, contact wheels, rotor blades, etc., are not covered under this warranty.

Motor Disassembly Complete.

Important: Clean and inspect motor parts for wear or defect before assembling.

Motor Assembly:

1. Hold the rotor in a vise equipped with aluminum or bronze jaws so that the threaded spindle is pointing up.

2. Install the 52467 Spacer onto the rotor.

3. Install the 31632 Front Bearing Plate and the 02552 Bearing onto the rotor.

4. Install the 31633 Rotor Nut hand tight by turning it counterclockwise. (Left Hand Thread)

5. Check the fit between the front of the rotor and the face of the bearing plate. The clearance should be .001"- .0015" (0.3mm – 0.4mm). Note: A.001" (0.3mm) feeler gauge can be used to check the clearance. If the fit is too loose, remove the rotor nut and select a .001" (0.3mm) thick

shim from the 01277 Shim Pack. Place the .001" (0.3mm) shim in between the 02552 Bearing and the inside of the 31633 Front Bearing Plate. Install these components onto the rotor and make the rotor nut hand tight to hold them in place. Check the clearance. Repeat this process as necessary until the correct clearance is established.

6. With correct clearance established, use a 22mm crowfoot/torque wrench and tighten the 31633Rotor Nut. (Torque to 17N·m/150 in. lbs.)

7. Position the rotor in the vise equipped with aluminum of bronze jaws so that the threaded spindle is pointing up. Install the 31644Washer and the 31634 Timing Belt Pinion. (Left Hand Thread) Tighten with a non-marring strap wrench. (Torque to 17N·m/150 in. lbs.)

9. Install the 54976 Cylinder so that the line-up pin fits into the hole in the front bearing plate.

10. Install the 54977 Rear Bearing Plate and the 02651 Bearing. Note: Use the 96239 Bearing Press Tool so that the raised center portion is positioned

against the inner race of the 02651 Bearing. Use the 96232 Arbor Press (#2) to carefully press the bearing down until it touches against the bearing seat on the inside of the rear bearing plate. This should create a snug fit between the bearing plates and the cylinder. Note:A “snug fit” allows the cylinder to be shifted from side to side with slight finger pressure while still trapping the cylinder so that it is not loose or sloppy between the bearing plates.

11. Apply a small amount of petroleum grease to the exposed shield of the 02552 Bearing and then install the 52467 Spacer over the timing belt pinion and washer. Position the spacer so that it is centered on the 02552 Bearing and the grease sticks it to the bearing.

12. Carefully install the motor into the 31650 Housing using the line-up pin as a guide for positioning the motor correctly in the housing.

13. Install the 31638 Gasket, and the 31637 Motor Cover with the 01790 Screws (5), and the 01791 Washers (5). Use a 5mm hex key to fasten these

components. (Torque to 9N·m/80 in. lbs.)

14. Add several drops of the 95842Dynabrade Air Lube (10W/NR or equivalent) through the air inlet fitting, connect the machine to the air supply hose, and turn on the air supply to test run the air motor.

15. Shut the air supply and disconnect the machine from the air supply hose.

16. If the air motor functions properly, install the 31645 Timing Belt and the 31661 Snap Ring. Carefully rotate the timing belt and gear mechanism by hand

to check for smooth operation and proper belt tracking. Important: If the air motor does not function properly, disassemble and make the necessary adjustments. If the timing belt and the related drive mechanism does not function properly, disassemble and make the necessary adjustments.

17. Use a Phillips

screwdriver to install the 31678 Screw and the 31646 Belt Guard.

18. Use a 2.5mm hex key to install the 96030 Screws (2) and the 31636 Cover Plate.

19. Install the abrasive belt and apply the belt tension.

20. Add several drops of the 95842Dynabrade Air Lube (10W/NR or equivalent) through the air inlet fitting, connect the machine to the air supply hose,

and turn on the air supply.

21. With the machine off the work surface, carefully run and track the abrasive belt.

Motor Assembly Complete. Sander Assembly Complete.Please allow 30 minutes for adhesives to cure before operating tool. Important: Motor should now be tested for proper operation at 90 PSIG. If motor does not operate properly or operates at a higher RPM than marked on the

tool, the tool should be serviced to correct the cause before use. Before operating, place 2-3 drops of Dynabrade Air Lube (P/ N 95842) directly into air inlet with throttle lever depressed.
