Problem
Causes
Solutions
The remote control
won’t control the
wrecker
The wrecker is
being controlled
by the control
panel
Use the touchscreen interface to activate remote
control mode.
The remote
control battery is
dead
Recharge the battery. The battery charger is inside
the left-hand side control panel.
The antenna on
the remote
control receiver
is broken
Replace the antenna. It is located on the right side of
the wrecker, just above the oil reservoir.
The boom lowers
on its own
The holding
valves are not
adjusted
properly
Adjust the holding valves.
Rubber or
silicone particles
in the hydraulic
fluid are stuck in
the holding
valves or
cartridges
Fully lower the boom. Loosen the nut that locks the
set screw on the cartridge. Turn the set screw
clockwise until it stops. This opens the valve
completely. Fully retract and extend the boom
several times. This flushes the cartridge and may
release the particles.
Adjust the cartridge (see Section 4.4.2 Adjusting the
counterbalance valves (CBCG-LJN)).
Try the boom again to see whether the problem is
solved.

faulty
Replace and adjust the cartridge (see Section 4.4.2
Adjusting the counterbalance valves (CBCG-LJN)).
The boom
cylinder is faulty
Check the boom cylinder and have it repaired or
