MAINTENANCE
• WARNING Unplug the unit and release air pressure from the
tank before performing maintenance.
• WARNING
Wear appropriate personal safety equipment
such as safety glasses and gloves.
NOTE 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.
NOTE 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.
NOTE Follow engine owner's manual for engine
maintenance schedules and procedures.
NOTE Any service operations not included in this
section should be performed by an authorized
service representative.

BELT ADJUSTMENT _______________________________
CHECKING BELT TENSION 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 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 table at right.
Compare the reading on the tension gauge to the table below.
Deflection in Inches Min. Tension (Lbs.)
0.17 3.0
Max. Tension (Lbs.)
6.0
