SECTION 8 - MAINTENANCE

Any unauthorized modification or failure to 
maintain this equipment may make it unsafe and 
out of factory warranty. 
 

 
 
 
If performing 

more than visual inspections, disconnect 
driver engine battery cables and open manual 
blow-down valve. 

 
Use extreme care to avoid contacting hot 
surfaces (heat exchange and piping, air receiver 
and air discharge piping, etc.). 
 
Never operate this machine with any guards 
removed. 
 
Inch and metric hardware was used in the design 
and assembly of this unit.  Consult the parts 
manual for clarification of usage. 

 
GENERAL 
 

In addition to periodic inspections, many of the 
components in this unit require periodic servicing 
to provide maximum output and performance.  
Servicing may consist of pre-operation and post-
operation procedures to be performed by the 
operating or maintenance personnel.  The primary 
function of preventive maintenance is to prevent 
failure, and consequently, the need for repair.  
Preventive maintenance is the easiest and the 
least expensive type of maintenance.  Maintaining 
your unit and keeping it clean at all times will 
facilitate servicing. 
 

SCHEDULED MAINTENANCE 

 
The maintenance schedule is based on normal 
operation of the unit.  In the event unusual 
environmental operating conditions exist, the 
schedule should be adjusted accordingly. 

COMPRESSOR OIL LEVEL

 
The oil level should be checked before the unit is 
operated.  The optimum operating level is midway 
of the sight tube on the side of the receiver tank.  
See the decal beside the sight tube.  If the oil level 
is not in the “OK” range, make appropriate 
corrections (Add or Drain).  A totally filled sight 
tube in which the level is not visible indicates an 
over-full condition and requires that oil be drained. 
 

AIR CLEANER

 
This unit is equipped with AIR FILTER 
RESTRICTION INDICATOR on the front panel, 
serving both compressor inlet air cleaners. 
 
This should be checked daily during operation.  If 
the indicator shows (red) with the unit operating at 
full speed, servicing of the cleaner element is 
necessary. 

Also weekly, squeeze the rubber valve (pre-
cleaner dirt dump) on each air cleaner housing to 
ensure that they are not clogged. 
 
If flagged, the air filter restriction indicator must be 
reset after unit is shut down and the air cleaners 
are serviced.  Reset by pushing button on top of 
indicator. 
 
To service the air cleaners on all units proceed as 
follows: 
 
1. 

Loosen outer wing nut and remove cover.  
Remove element. 

2.  Inspect air cleaner housing for any 

condition that might cause a leak and 
correct as necessary. 

3. 

Wipe inside of air cleaner housing with a 
clean, damp cloth to remove any dirt 
accumulation, especially in the area where 
the element seals against the housing. 

4. 

Inspect element by placing a bright light 
inside and rotating slowly.  If any holes or 
tears are found in the paper, discard this 
element.  If no ruptures are found, the 
element can be cleaned. 

5.    If a new air filter element is to be used 

check it closely for shipping damage.
