5HP INLINE PUMP MANUAL REV030921 

 

 

 

 

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.
