Problem
Causes
Solutions
The winches
cannot be
disengaged
The solenoid has
no power
Using a multimeter, see whether the solenoid wiring
is carrying a current.
The air pressure
is too low
Check for an air leak or a bent hose.
The winch
solenoid is faulty
Replace the solenoid. Follow the air line to locate the
solenoid, which is near the winch.
The cylinder
piston may be
broken or bent
(only for RPH
15000 winches)
Replace the cylinder.
The wrecker lacks
power and runs too
slowly
The hydraulic
pump is faulty
Check and adjust the hydraulic pressure (see
Section 4.4.1 Adjusting the hydraulic pressure (main
relief)).
The control panel
doesn’t show
whether the boom
is centred
The sensor is not
detecting the
position of the
boom
Move the boom all the way to the front of the wrecker
to ensure that it can be detected by the sensor.
The boom
position sensor
is faulty or
absent
Replace the sensor. It is located in the centre (left-
right) of the wrecker, on the structure retaining the
rotation lock. To access it, move the sliding rotator to
the rear of the wrecker.
The winch cable
stops too quickly or
too slowly in free
spool mode
(disengaged)
The air pressure
on the cable
tensioner is too
low or too high
Increase or decrease the air pressure on the cable
tensioner. The regulator is located between the two
main winches.
This is a trial and error adjustment. Keep adjusting
the air pressure of the cable clamp balloon until you
find the right setting.
