Condition
__________________________________________________________________________________________
Mach ne stops aerating (pump

Water system engages (pump
belt and gear case drive shaft
rotate), but no aerat on holes are

produced or aeration hole depth
is shallow or incons stent.

Troubleshooting
Possible Cause
Mach ne not mov
i
ing.
Inadequate water supply.
Pl
ugged inlet water f lter.
i
El
ectrical problem.
Air in system.
Soil density or mo sture content.
i
Pl
ugged nozz es, worn nozz es or
l
improper nozz e conf guration.

NOTE: Check operation of nozz
by aerating over a piece of
cardboard, then inspect

cardboard.
Gear or cam damage in gear case.
Leak i
n high pressure water sys-
tem.

Correction
Norma condition of nter ock sys-
l
tem. Operator must hold engage
button in to aerate with tract
bail in neutral.
Check for k nked water supply
i
hose, restr ction in line or part ally
i
open va ve at water source.
l
Check water pressure at gauge
when pump is engaged. If pres-
sure drops to less than 15 PSI,
but was
initi
ally higher, replace
water f lter.

Chapter 5 - E ectrical System
l
With engine OFF and water supp-
ly connected, open high pressure
bleed valve and bleed air out of
system.
If hole depth was sat sfactory
before in another area, different
nozz e configuration may be re-
l
quired.
l
Stop engine, open high pressure
bleed valve, then inspect noz-
les
zl
es. Check for plugged nozz es.
Ver fy s ze and quantity (see Noz-
i
i
zle Si
ze and Approximate Depth
Chart). Nozz es that are too large
l
will cause loss in pressure and
could cause damage to the ac-
cumulator and other water sys-
tem components.
Inspect gear case for gear or
cam damage and repair as neces-
sary.
Check for eaks w th water sys-
l
tem engaged. Stop engine, open
high pressure bleed valve and
repair eaks as necessary.
l
NOTE: Excessive water exiting
between pump head and
crankcase ndicates pump wear
i
or damage. Excess ve water exit-
ing from shim area below gear-
case indicates valve wear or
damage. Do water system tests
and make repairs as necessary.
