For Various Abrasive Power Tools Safety Booklet included with tool must be read and understood before operating any portable pneumatic tool! • This page must be read and understood by operating personnel and safety manager. Protection to operating personnel, as well as adjacent areas, shall be maintained at all times. • Always comply with: General Industry Safety & Health Regulations (www.osha.gov), EN Standards for Hand Held Non-Electric Power Tools (www.cen.eu), American National Standards Institute (www.ansi.org) and Regional Regulations. • Additional safety reference materials are available...

COMPRESSED AIR SUPPLY SYSTEM Lubricator Setting 1 Drop /Minute per 20 SCFM Dynabrade recommends one drop of air lube per minute for each 20 SCFM (566 L/Min) Example: If the tool specifications state 40 SCFM (1,133 L/Min), set the drip rate of your lubricator at 2 drops per min.

COMPRESSED AIR SUPPLY SYSTEM (CONT.) COMPRESSED AIR SUPPLY SYSTEM (CONT.) COMPRESSED AIR SYSTEMS SHOULD INCLUDE THE FOLLOWING: 1. AIR INTAKE FILTER Incoming air must be filtered to remove dust and other contaminants. 2. AIR COMPRESSOR The filtered air is compressed using; a screw, or reciprocating compressor. 3. AIR COOLING/DRYING Air usually contains a significant amount of water vapor. As air is compressed its temperature is dramatically raised, so cooling of the compressed air is required. As the air is cooled, the water vapor condenses and water is removed. 4. AIR STORAGE A tank called an...

SELECTING A COMPRESSOR (CONT.) C) COMPRESSOR HORSEPOWER (hp) – Use the determined total demand SCFM (L/Min) and add approximately 20% for system variables. Add ______% for (your) future growth. If the above total equals less than 100 SCFM(2,832 L/Min) divide this total by 4 to find the compressor hp. If the total is over 100 SCFM(2,832 L/Min) divide by 5 to find the compressor hp. Example: System requirements = 165 SCFM (4,673 L/Min) @ 100 PSIG (6.9 Bar) 165 ÷ 5 = 33 hp. Suggested Compressor Size: ~30 to ~40 hp. AIR STORAGE TANK SIZE - As a general rule, the larger the tank (receiver) the better....

PREVENT AND ELIMINATE AIR SUPPLY RESTRICTIONS Common causes of restriction: • The air supply hose is too long. • The inside diameter (i.d.) of the hose is too small. • The air connections or fittings have an inside diameter that is too small. • There are too many air connections or fittings being used. • If an inline filter is being used, the unit may be too small or the filter element may be plugged. • If an inline regulator is being used, the unit may be to small, not adjusted properly or defective. • The air supply hose, air fitting, air tool inlet or air tool exhaust may be plugged....

AIR PLUGS AND COUPLERS PLUGS COMPARE AIRFLOW SCFM(LPM) Common Plug HOW TO MEASURE A TYPICAL PLUG Dynabrade Plug NPT (National Pipe Thread) is the thread size. (i.e. 1/4" NPT) Thread Size • Dynbrade plugs provide maximum air flow NOTE: All information is based on the size of the INSIDE DIAMETER @ 90 PSIG (6.2 Bar) in conjunction with the mating coupler. • Plugs are available in the following sizes: 1/4", 3/8"and 1/2" NPT. IMPORTANT: It is not always advisable to use an air plug and coupler to connect an air tool to the air supply hose. Contaminants can enter the air tool through plug and coupler...

1. REDUCE OR ELIMINATE CONDENSATION (WATER VAPOR) FROM THE AIR SUPPLY • Water traps and drains • After-coolers • Refrigerated air dryer 2. PREVENT DEBRIS FROM ENTERING THE AIR MOTOR • Filter the air. • Keep the air inlet connections, plugs and couplers clean, free of dust and debris. • Keep exhaust mufflers and elements in place. Muffler elements provide a barrier that will prevent dust from being pulled into the air motor. • Do not use compressed air to blow-off the tool, this could force debris into bearings. 3. LUBRICATE THE AIR MOTOR • Use an automatic lubricator to supply the correct weight...
