Troubleshooting

SYMPTOM

CAUSE

REMEDY

Carriage slows and stops but

will not regain speed

Cam arm on shifter is not adjusted

correctly

Adjust cam arm or upper rail

Reversing valve not shifting correctly

Check reversing valve for proper function and

correct if needed

Distortion in valve body could restrict

spool if bolts are too tight

Loosen bolts one at a time

Machine will advance manu-

ally but not in “Pave” mode

Check valve could be stuck

Tap check valve and replace if recurs

Cam arm is set in wrong position

Cam arm is too far one way and needs to be

adjusted

Augers are functioning nor-

mally, but tubes are stopping

under load

Reversing valve could be contaminated

affecting relief or relief is set too low

Disassemble relief and clean. Set pressure to

1200psi. (Verify pressure before performing

this)

Reversing valve may be damaged or

tube motor is damaged or worn

Replace revering valve or motor

In one direction tubes func-

tion correctly but after shift

and direction change, tubes

stop

Quick disconnect fitting is malfunc

tioning

Change quick disconnect

Tubes are operating under

load but augers are not

Augers are seeing too much concrete

Lessen amount of concrete in front of augers

Motor for auger is damaged

Change auger motor

Quick disconnect is faulty on auger

hose

Change quick disconnect fitting

There is noise coming from
tube bearings and bearings

are extremely hot. Tubes may

be stopping under load

Tube bearings are damaged and need

replaced

Replace bearings

Tubes do not automatically

reverse or carriage does not

fully skew on shift

There is an obstruction blocking full

travel

Remove obstruction

Center pivot nut is too tight

Loosen pivot nut

Center pivot shaft is binding

Take apart and clean shaft

Roller tubes and augers stop

under load

Relief valve is set too low

Check relief pressure for 1800psi. If faulty,

replace and reset.

Roller tubes and augers have

low rpm’s or low power

Pump is faulty or worn

Replace drive pump

Roller tubes spin in correct

direction but carriage doesn’t

skew accordingly

Skew cylinder hoses are backwards

Swap hoses around on skew cylinder

Roller tubes on carriage will

not auto reverse after lever is

switched on reversing valve

Cartridges are stuck in the MV1 and

MV2 locations on reversing valve

Replace both cartridges
