TROUBLESHOOTING
SYMPTOM (Cause)
Discharge Augers do not turn
(Object in auger, hydraulic fluid levels,
hydraulic pressure relief valve, hydraulic
pump, hydraulic motor, stripped gear,
broken chain)
Magnehelic Gauge reading
greater than normal operating
range
(Dust Collector Filter Cartridges)
ACTION
Run Discharge Auger in reverse to dislodge
item. Dismantle Discharge Auger if object
still lodged.
Fill hydraulic system with hydraulic fluid.
Check line pressure at by-pass gauge, reset
or replace hydraulic valve.
Test hydraulic pump pressure. Replace
hydraulic pump.
Bench test hydraulic motor. Repair or
replace hydraulic motor.
A reading greater than 10" (w.c) on
Magnehelic Gauge indicates clogged filters.
Decrease engine RPM to idle speed and
disengage clutch while allowing engine to
run. Pulsers will clean down the filters. Once
gauge reads back into the normal operation
range of 3" – 10" (w.c), re-engage clutch and
increase RPM to operating speed.
If Magnehelic Gauge is reading above 10"
(w.c.), perform After Use procedure. Inspect
Pulser System and Filters. Replace filter
cartridges, if needed.
If Magnehelic Gauge is reading above 15"
(w.c.), shut down unit immediately. Replace
filter cartridges.
