MAINTENANCE
WARNING
l Disconnect, lock and tag the main power supply and release air
pressure from the system before performing maintenance.
NOTICE
l All compressed air systems contain maintenance parts (e.g. lubricating
oil, filters, separators) which are periodically replaced. These used
parts may be, or may contain, substances that are regulated and must
be disposed of in accordance with local, state, and federal laws and
regulations.
l Take note of the positions and locations of parts during disassembly to
make reassembly easier. The assembly sequences and parts illustrated
may differ for your particular unit.
l Any service operations not included in this section should be
performed by an authorized service representative.
ROUTINE MAINTENANCE SCHEDULE
l Check lubricant level. Fill as needed.
Daily or Before
Each Operation
l Drain receiver tank condensate. Open the manual
drain valve and collect and dispose of condensate
accordingly.
l Check for unusual noise and vibration.
l Ensure beltguards and covers are securely in place.
l Ensure area around compressor is free from rags,
tools, debris, and flammable or explosive materials.
l Inspect air filter element. Clean or replace if

n Filter Element Replacement
1. Unscrew and remove the wing nut (A) securing the filter housing (B) to its base
(C).
2. Remove the filter housing and withdraw the old filter element (D). Clean the
element with a jet of air or vacuum.
3. Install a new filter element and replace the housing, securing it in place with the
wing nut previously removed.

n Belt Adjustment
Checking Belt Tension
n
Check belt tension occasionally, especially if looseness is suspected. A quick
check to determine if adjustment is proper may be made by observing the slack
side of the belt for a slight bow when the unit is in operation. If a slight bow is
evident, the belt is usually adjusted satisfactorily.
Tensioning Belts
n
Belt tensioning can be achieved by loosening the motor anchor screws, pushing
the motor away from the pump, and retightening the motor anchor screws. The
motor can be easily moved by placing a prying tool beneath it. A commercially
available spreader or other belt tensioning device can also be helpful should
tensioning be necessary.
Follow the procedures outlined below to correctly set and measure belt tension.
1. Lay a straight edge across the top outer surface of the belt drive from pulley to
sheave.
2. At the center of the span, perpendicular to the belt, apply pressure to the outer
surface of the belt with a tension gauge. Force the belt to the deflection
indicated in the following table and compare the reading.
Deflection in Inches
0.17
Belt Tensioning
Ensure the pulley and sheave are properly aligned and the motor anchor screws
are adequately retightened prior to restarting the compressor.
l Improper pulley/sheave alignment and belt tension can result in motor
overload, excessive vibration, and premature belt and/or bearing
failure. To prevent these problems from occurring, ensure the pulley
and sheave are aligned and belt tension is satisfactory after installing
new belts or tensioning existing belts.
