Important Operating, Maintenance and Safety Instructions
Carefully read all instructions before operating or servicing any Dynabrade®Accessories.
Installation Instructions:
Notice: Close the air line system by turning off the air pressure in the area where the FRL unit will be installed.
1. Be sure to select a proper site for the FRL unit by locating the area of the air line system that is as close to the actual work area as possible.
Note: This site should be free of direct sunlight, excessively high temperatures, and hazardous chemicals.
2. Using either 3/8" or 1/2" air fittings refer to other side for proper model and air fitting sizes. Mount the FRL unit, or individual units, in the air line system with
the arrows on the unit pointed in the direction of the air flow within the air system. Failure to do so can damage components(s).
3. How to reduce from the 1/2" NPT openings to 3/8"- If required, use the two reducer bushings shipped with this item. (See front page for further details).
4. Fill the oil bowl with air tool oil. Please see the section below on lubrication.
5. Open the air line system and check for leaks around the FRL unit.
Standard Operating Instructions:
Filter (Filtration)
1. If the water level exceeds the maximum limit on the filter bowl, please drain the filter. This is done by pushing the orange button on the bottom of the filter.
Regulator (Regulation)
Warning: Set the regulator while verifying the displayed values of the inlet and outlet pressure gauges. Turning the knob excessively can cause damage to the
internal parts. Pressure regulator knob should be adjusted by hand only. Do not use tools.
1. Regulation of air pressure is controlled by the black knob found on the regulator portion of the FRL unit. The air pressure is measured by the gauge on the front.
2. Maximum operating air pressure is 145 PSIG.
3. To increase the air pressure, be sure to unlock the knob before adjusting. Pull the pressure regulator knob to unlock.
(You can visually verify this with the “orange mark” that appears in the gap). To decrease the air pressure, turn the black knob
counterclockwise. Once the proper air pressure is established push the pressure regulator knob to lock. When the knob
is not easily locked, turn it left and right a little and then push it (when the knob is locked, the “orange mark,” i.e., the
gap will disappear).
Lubricator (Lubrication)
1. Oil fill port; Check valve allows oil to be added to the Lubricator oil reservoir bowl without shutting off the air supply and interruption to work operations.
2. Remove the fill black cap plug by turning it counterclockwise.
3. Fill the bowl to the fill line with air tool oil. Use Dynabrade P/N 95842 Air Lube or equivalent air tool oil (10W/NR).
4. Replace the fill plug by turning in clockwise.
5. After filling Lubricator bowl with oil, oil is dispensed within 10-20 seconds. (Response time for many competitor units: 15-20 minutes.) Oil Flow Adjustment
Control, allows for easy, fast and accurate dispensing of oil.
6. Oil feed sight dome; Allows visible adjustment in the amount of dispensed oil (dropped) into the flow of compressed air.
7. Turn the sight dome valve clockwise to decrease oil drop rate and turn counterclockwise to increase oil drop rate. The higher the air flow (SCFM) rate, the
more the oil drop rate needs to be. With tool running, adjust to 1 drop per minute for each 20 SCFM of air flow. Flow rates for individual tools are supplied by
tool manufacture.
Maintenance Instructions:
Other than when adding oil to the lubricator, always turn off air pressure and discharge all air inside FRL unit before performing any maintenance procedures.
Filter:
1. Remove the filter cover to inspect the filter assembly and check the amount of debris that may be collected on the filter cartridge itself. Clean the filter with
soap and water. If the filter is damaged or contains heavy debris, it must be replaced. Refer to the parts breakdown for more information. Replace the
element every 2 years or when the pressure drop becomes 15 PSIG (1 Bar), whichever comes first, to prevent damage to the element.
2. Clean the clear portion of the filter bowl with soap and water. Warning: Polycarbonate Bowl. Do not use any cleaning fluids that may be hazardous to plastic
materials. Examples of incompatible chemicals are thinners, carbon tetrachloride, chloroform, kerosene, sulfuric and nitric acid.
Regulator:
1. No maintenance expected.
Lubricator:
1. Fill oil as required to fill line on bowl.
