FAULT

PROBABLE CAUSE

CONTROL/REMEDY

No boom movements when activated.

Insufficient hydraulic pressure.

Check oil pressure.

Check tractor hydraulic oil level.

Insufficient oil supply.

Oil flow must be between 4 gpm (15 l/min) and
21 gpm (80 l/min).

Check tractor hydraulic oil level.

Blown fuse(s).

Check / replace fuse in junction box.

Bad / corroded electrical connections.

Check / clean connections, multi plugs etc.

Insufficient power supply.

Voltage on activated solenoid valve must be more
than 8 volts.

Use wires at least 10 awg. (4.0 mm²) for power supply.

Defect relay / diodes in junction box.

Check relays, diodes and soldering at PCB in junction
box. LED diodes indicate boom functions.

Clogged restrictors in bypass block.

Remove and clean restrictors in bypass block (See
hydraulic diagram). Change hydraulic oil + filter.

Wrong polarity.

Check polarity. Red positive (+) Black negative (-).

Boom lift raises to max. position when tractor
hydraulics are engaged.

Wrong oil inlet to bypass block.

Connect hydraulic snap couplers opposite in tractor
outlets, or engage spool valve lever in opposite
direction.

Back pressure in return line exceeds 290 psi.

Connect the return line with free flow to hydraulic oil
reservoir.

Divide return line in two and lead return oil back to
reservoir via two spool valves.

Oil heats up in Closed Center systems.

Bypass valve does not close properly.

Check / close (screw in) by-pass valve.
