Note:
These are standard maintenance procedures which the QED Environmental
Systems “warranty” does not cover. QED does not manufacture
compressors. Always use the manufacturer’s instructions and
recommendations when installing, using and servicing the compressor.
These notes are included as a general guide only.
Troubleshooting
Although QED usually does not supply the compressor, this section is provided to help the
operator. If the system receives clean, oil-free air from the compressor, maintenance will
be significantly reduced.
I. Problem: Slow Pumping or Insufficient Pressure
Solutions:
A. Clogged filter element: clean or replace.
B. Leaks in air lines: retighten or replace.
C. Insufficient air capacity: add compressor capacity, consult dealer.
D. Head valves: clean or replace.
E. Slipping belts: adjust or replace.
F. Power cord is too long for the power needed, causing a voltage drop: use a short cord with
large wires. Do not coil the power cord.
II. Problem: Excessive Oil Consumption
Solutions:
A. Too much oil: drain out excess to level mark on sight glass.
B. Worn rings: replace rings.
C. Clogged air intake filters: clean or replace.
D. Improper Oil: check the manufacturer’s recommendation.
