Stationary Air Compressor System Operating Instructions

4 - Operator Maintenance Checks

Do not perform maintenance tasks beyond the scope 
of this manual unless authorized as a SCOTT trained 
and certified service technician. Performing service 
procedures  without  proper  training  may  lead  to 
permanent equipment damage or personal injury.

Operator Maintenance Checks

To ensure reliability of the system, the operator is 

responsible for observing the unit during operation and 

performing necessary maintenance checks as described 

in  this  section.  Maintenance  and  service  procedures 

beyond the scope of these instructions should ALWAYS 

be performed by a SCOTT trained and certified service 

technician. 

Service Schedules

Maintenance  and  service  procedures  for  the 

Stationalry Air Compressor breathing air system must 

be  performed  by  a  SCOTT  trained  and  certified 

service technician. The operator is responsible for 

monitoring the compressor run time and notifying the 

System Administrator when the intervals of fifty (50) 

and one hundred (100) hours occur. The compressor 

run  time  and  service  due  information  is  available 

from the X4 Controller using the Information Button 

(INFO) as described in Chapter 3, STARTING AND 

OPERATING. 

After every fifty (50) hours of compressor running time, 

the  following  maintenance  should  be  performed  by  a 

trained technician:
–  Replace the Air Purifier elements

–  Change the break-in compressor oil (perform 

subsequent oil changes every one hundred (100) 

hours of compressor run time)

–  Check the tightness of all major fasteners including 

Head Bolts, valve retainers, mounting bolts, etc.

After  every  one  hundred  (100)  hours  of  compressor 

running  time,  the  following  maintenance  should  be 

performed by a trained technician:
–  Replace the air intake filter element

–  Change the compressor oil
–  Check the Auto Drain system
–  Check all other auxiliary systems 

The air quality produced by the LIBERTY System should 

be checked regularly at the following intervals: 
Every thirty (30) days:
–  If installed, calibrate the Carbon Monoxide Monitor 

using SCOTT Test Kit P/N AB16-0533.

Every ninety (90) days:
–  Take  an  air  sample  to  verify  air  quality  meets  or 

exceeds CGA Grade E breathing air.

An air sample is required after installation and any service 

to the system that effects the breathing air path, that is, 

from the air purifier filters on. For example, changing the 

air filters would require taking an air sample. 
Other  major  compressor  maintenance  is  required  at 

specific time intervals depending on the make and model 

of the compressor. The operator should keep the System 

Administrator informed as to the total compressor run 

time so these maintenance tasks can be scheduled.

The operator should perform the following checks each 

time the Stationary Compressor System is used or, at a 

minimum, once a week.

WITH THE SYSTEM OFF:

–  Check the level of the compressor oil. Refer to the 

Material Safety Data Sheet (MSDS) for instructions 

on the safe handling of any chemicals used in the 

maintenance or servicing of this equipment

–  Check the Belt condition and tension

–  Check for loose components
–  Check the Remote Air Intake for leaks

WITH THE SYSTEM RUNNING:

–  Run the compressor system to operating temperature 

(approximately 30 minutes) and verify operation of 

the auto drain system.

NOTE

SCOTT recommends that the compressor system 
should be operated for at least thirty (30) minutes 
once a week to maintain optimum performance and 
to identify any problems.
