Troubleshooting
The cause of an improperly functioning water system is
best diagnosed with the use of proper testing equipment
and a thorough understanding of the complete system.
Refer to the Testing section of this Chapter for precau-
tions and specific test procedures.
NOTE: The water aeration system operates under very
high pressures and severe duty cycles. Performance of
the water system will be gradually reduced over aperiod
of time due to normal wear in the pump, valve and
accumulator. Ifyouperform water system tests toisolate
a possible problem, such as reduced hole depth, it is
recommended that ALL tests be performed in the order
listed even if the apparent problem has been isolated,
such as low accumulator pre-charge pressure. This will
verify that all components are operating properly.
The charts that follow contain detailed information to
assist in troubleshooting. There may possibly be more
than one cause for a machine malfunction.
ALL POSSIBLE CAUSES SHOULD BE CHECKED IN
THE ORDER IN WHICH THEY ARE LISTED ON THE
CHARTS.

___________________________________________________________________________________________
Machine does not start aerating
when engage button is pushed in
(pump belt does NOT rotate).
Transport wheels not fully raised
(unit lowered to aerate mode).
Check to make sure transport
wheel arms are fully raised (unit
in aerate mode).
Low inlet water pressure.
Check that water pressure gauge
reads 20 to 30 PSI or more. If
pressure is low, obtain proper
water supply source.
Sheared pump clutch key.
Electrical problem.
Repair.

Electric brake clutch (valve clutch)
out of adjustment.
Check air gap at electric brake
clutch and adjust if necessary.

________________________________________________________________________________________________________________________________________________________
Machine makes unusual noise
when first starting aeration.
Air in system. NOTE: Relief valve
may “squeal” for a short period of
time during initial startup due to air
in the system.
With engine OFF and water supp-
ly connected, open high pressure
bleed valve and bleed air out of
system. Repeat procedure if
noise continues.
Damaged component.
Check for damaged components
and repair or replace as neces-
sary.
