OPERATING INSTRUCTIONS
1.
Make sure the Air Inlet Ball Valve (3) is in its closed position. (See Figure C.)
2.
Connect one end of an air hose to the Quick Coupler (2) on the Barrel Pump. (See Figure C.)
3.
Connect the other end of the air hose to an air compressor. (See Figure A.)
4.
Turn on the air compressor, and set its regulator to 10 PSI. Do not exceed
10 PSI. (See Figure C.)
5.
Set the Regulator (4) on the Barrel Pump to 10 PSI.
6.
Turn the Air Inlet Ball Valve (3) to its open position to pump the liquid from the Short Oil Tube (21) of the Barrel Pump into a proper container. (See Figure C.)
7.
NOTE: The rate of flow of the liquid being pumped depends on its fluid viscosity. To adjust the Regulator’s (4) PSI and therefore alter the rate of flow of the liquid, lift up and twist the Knob on the Regulator. Then, push in on the Knob. To increase air pressure, turn the Knob clockwise. To decrease the air pressure, turn the Knob counterclockwise. Do not exceed 10 PSI.

To stop the flow of liquid being pumped from the barrel, turn the Air Inlet Ball Valve (3) to its closed position. (See Figure C.)
9.
When finished using the Barrel Pump, make sure the Air Inlet Ball Valve (3) is in its closed position. Turn off the air compressor. Hold a proper container under the Short Oil Tube (21) and open the Air Inlet Ball Valve again to release any compressed air in the Barrel Pump. Turn the Regulator (4) to its lowest setting. Turn the Air Inlet Ball Valve to its closed position. Then, disconnect the air hose from the Barrel Pump.
10.
If necessary, unscrew and remove the Barrel Pump from the barrel. Replace the bung on the barrel. Wipe the Barrel Pump dry. Then, store the Pump in a clean, dry, safe location out of reach of children. (See Figure C.)
INSPECTION, MAINTENANCE, AND CLEANING
1.
WARNING! Prior to performing any inspection, maintenance, or cleaning
of the Barrel Pump, make sure to disconnect the air hose from the tool. Then,
open the Air Inlet Ball Valve (3) again to release any compressed air in the Barrel
Pump.
2.
Before each use, check the Barrel Pump for loose connections, damaged parts,
and any other condition that will affect the safe and proper operation of the tool.
If there is a problem with the Pump, immediately discontinue its use and have the
tool repaired before further use.
3.
To clean the exterior of the Barrel Pump, wipe with a clean, damp cloth using
a mild detergent or mild solvent. Do not immerse the tool in liquids.
4.
To clean the interior of the Barrel Pump, immerse the lower section of the
Pump into a container filled with a mild detergent or mild solvent. Connect the
Barrel Pump to an air compressor and pump the detergent or solvent through
the Pump and into a proper waste container until the detergent or solvent being
pumped is itself clean. When finished, disconnect the air compressor, releasing
all remaining pressure from the Pump. Remove the Pump from the container of
detergent/solvent. Then, thoroughly dry the Pump.
5.
Always dispose of oil and other liquids according to local waste authority
guidelines.
6.
When storing, always store the Barrel Pump in a clean, dry, safe location out of
reach of children.
7.
CAUTION! All maintenance, service, and repairs not mentioned in this
manual must only be performed by a qualified service technician.
