Operation
1.
The unit is shipped with pump break-in oil and should be ready to operate. Be sure to check for proper oil level
before running. Break in oil should be change after 100 Hours of operation (active pumping time). See
maintenance section for more information on oil changes and frequency.
2.
Oil pressure on startup will vary due to ambient temperatures but should not exceed 100 PSI. Once the unit is
allowed to run a few cycles and come to optimal operating temperature, oil pressure should stabilize at 20-35
PSI. If the oil pressure remains high or drops too low, it can be adjusted as follows:
3.
This pump is designed to operate with 1.85 Pints, or roughly 1 quart of oil.
4.
It is strongly advised to use only Airbase Industries piston compressor oil. Check with your warranty/extended
warranty guidelines to verify oil selection and use. Oil used in the pump must fall under the following criteria:
synthetic, SAE grade 30, non-detergent, piston compressor oil. Failure to use the correct oil will void your
warranty.
Oil level should be to the center of the red circle in the sight glass. Oil level WILL
drop once the unit turns on and oil begins to circulate.
When facing the oil pressure gauge. Look to the 7 o’clock
position. You will see an acorn nut (#32). Remove the acorn
nut and be careful to not lose the rubber seal (#4) sitting
behind it. Loosen but do not remove the set nut (#2). You will
see a flat head screwdriver slot in the end of the adjustor
(#16). To increase pressure, turn the adjustor clockwise; to
decrease pressure turn then adjustor counterclockwise. Turn
no more than ½ turn at a time. Then allow the unit to cycle to
measure the adjustment.
TAKE CARE
when lowering pressure not to back the adjustor
out completely.
Once oil pressure is set, hold the adjustor (#16) in position
and retighten set nut (#2). Replace rubber seal (#4) and
reinstall acorn nut (#32).
FAILURE
to reinstall acorn nut, seals, or set nuts can result in
oil leaks.
WARNING: Always make sure main power is off prior to touching belts or other
moving parts of the pump.
