10HP - 20HP Scroll Enclosure Air Compressors 

SCHEDULED MAINTENANCE 

                                               Per OSHA regulations, lockout 
compressor system from all power sources BEFORE      
performing any maintenance. 

INTAKE FILTER                                                                    

1. Remove the small rear access panel.                                          
2. Remove the wingnut on the filter housing and drop the 
cover down. Remove the element without removing the cover 
from the enclosure cavity.                                                          
3. Clean the inlet filter element with compressed air or                
replace with a new element.                                                       

NOTE: 

Never clean filter element with solvents or water.               

VENTILATION SCREEN                                                             

1. Remove the ventilation screen located at rear of the unit.                                                                                              
2. Clean with compressed air or soap and water if necessary.     

INSPECT V-BELT TENSION                                                           

1.  See page 9 of Operation Manual, IN562802AV. 

GREASE COMPRESSOR BEARINGS (Figure 7)                              

1. Remove the plastic dust cap from the airend.                          
2. Move the compressor pulley until the grease fitting is  
visible through the dust cap hole.                                                     
3. Use a grease gun extension adapter to engage the grease 
fitting and supply the proper volume of grease as indicated on 
the grease delivery chart. See chart below.

GREASE PIN CRANK BEARING (Figure 6)                   

1. Remove fan duct (2) (Key #5)                                             
2. Remove the nuts and bolts and then the fixed scroll from 
the air end.                                                                                 
3. Grease all three pin crank bearings as indicated on the 
grease delivery chart above.   

Use only Powerex genuine 
grease. Pump grease gun before 

feeding to eliminate air from grease passage of the needle 
adaptor. 
 

NOTE: 

Each pump of the grease gun equals 0.65g of grease. 

The volume of grease is less after the 2nd pump since some 
of the grease supply will remain in the grease passage.  

MAINTENANCE INDICATORS 

The PUMP MAINT indicator will activate when the running 
hours of 

any 

pump accumulates to a required maintenance 

interval.  The system is designed for multiple pumps to accu-
mulate hours evenly and for maintenance intervals to be ap-
proached simultaneously.  To prevent nuisance PUMP 
MAINT indications, all applicable maintenance counters 
should be reset after the required maintenance actions are 
performed.
