Troubleshooting
MQL Mist Lubrication System
Problem Cause Solution
No fluid output 1. Out of fluid.
2. Insufficient inlet air pressure.
3. Meter stroke failure.
4. Pulse generator cycle rate is set too
fast or too slow.
1. Check reservoir level.
2. Check inlet air- set to maximum.
3. Check for stroking of meter- use full
air line inlet pressure. Check for fluid
movement in capillary tubing at each
meter stroke. Loosen 5/6” brass hex
bleed screw 2 revolutions until only
fluid comes out- close screw tightly.
Recheck meter output by manually or
automatically cycling.
4. Adjust pulse generator cycle rate.
Reduced fluid output 1. Insufficient inlet air pressure.
2. Contaminated fluid supply. 1. Check air inlet pressure so that meter
operates “crisply”.
2. Non-lubricating fluids such as water
and solvents could cause premature
wear of internal parts. Consult factory
for rebuild kit.
Pulse generator not
functioning
1. Clogged air inlet screen. 1. Remove pulse generator and check
air inlet screen for particular matter. If
none found, replace pulse generator.
Blade Squealing 1. Feed rate too light
2. Blade running against flange on
wheel
1. Increase feed rate
2. Ensure blade is tensioned properly to
35 ft-lbs
Slow meter operation 1. Insufficient inlet air pressure. 1. Be sure maximum air inlet pressure is
available. A slow or incomplete return
could be caused by a broken sprint
or inadequate lubrication of the
U-cup. Rebuild meter.
Meter depressed and not
returning
1. Debris in fluid reservoir.
2. Broken return spring. 1. A piece of debris in the fluid could
cause the liquid pin to jam.
Disassemble and reassemble,
checking for foreign particles.
2. If a return spring is broken, rebuild
meter.
Fluid flowing continuously
out of the nozzle or reservoir
emptying without system
running.
1. Bad check valve. 1. The check valve seal is not
functioning properly. Check the seat
for cleanliness (or turn it over). Check
the seal spring.
Fluid accumulation in outer
tubing
1. Insufficient atomizing air exiting the
nozzle.
1. Increase the atomizing air flow.
2. Direct nozzle coupler outlet
downward to encourage excess fluid
to exit the nozzle.
Air bubbling upward into
fluid reservoir
1. Bad check valve. 1. Check the valve seat (check seal) for
possible leakage (turn over seat).
A static sealing o-ring may need
replacement. Use a rebuild kit.
