draulic oil tank. There is noise from the hy-
draulic pump.
The circulation valve is continuously open.
The standby pressure is too low.
There is a fault in the pump regulator.
The knob for adjustment of the tool speed
and/or the knob for adjustment of the product
speed is turned counterclockwise.
The standby pressure is too low.
There is internal leakage in the cylinder.
The hydraulic hose is blocked.
There is a fault in the pilot control valve.
A joystick is not in a neutral position when
you start the remote control.
There is a fault in the pilot control valve or
the spool in the pilot control valve is blocked
or damaged.
There is leakage in the check valves in the

Solution
Stop the product immediately. Do a check for
leaks in the hydraulic system. Replace parts
with new parts if it is necessary. Fill the hy-
draulic oil tank with hydraulic oil.
Do a check of the cable to the control mod-
ule. (DXR 95)
Do a check of the diode on the valve cap at
the bottom of valve block 1. If the circulation
valve is open, the diode does not light up. Do
a check of the cable to the control module.

Turn the knob for adjustment of the tool
speed and/or the knob for adjustment of the
product speed clockwise.
Start the remote control. Do not use the con-
trols on the remote control. Do a check of the
standby pressure on the remote control dis-
play. The pressure must be 20±5 bar/290±73
psi. If the pressure value is different, adjust
the pressure.
Extend the cylinder to its end position without
load. Do a check of the pump pressure in the
remote control display. The pump must oper-
ate at maximum pressure. If the pump does
not operate at maximum pressure, speak to
an approved service agent.
Operate the cylinder without load. Do a
check of the pump pressure in the remote
control display. If you get maximum pressure
but not full speed on the cylinder, the hy-
draulic hose is blocked. Replace the hydraul-
ic hose.
