Hydraulic Maintenance
Before performing any maintenance on the
hydraulics of the Attachment, ensure that circuit is
depressurized. If you believe that there is a hydraulic
leak, do not search for a leak with your hands, rather
use cardboard or a piece of paper to search for the
leak. The hydraulic circuit should be connected as
follows:
1)
Pressure In
-
This attaches to your Power Unit
’
s
high pressure line. On some units it may be
necessary to switch the male and female quick
connectors depending on the Power Unit
’
s
configuration.
2)
Motor Protection Valve (MPV)
-
The MPV protects
the motor from pressure surges that would
damage the motor
’
s internal seals by means of a
pressure relief valve.
3)
Supply Line
-
As the drum is only capable of
cutting when spinning in one direction, the supply
line should always run from the pressure port of
the MPV to the in port side of the motor.
4)
Return Line
-
The return line should connect the
out port side motor port to the relief port of the
MPV.
5)
Pressure Out (return line out)
-
Connect to the
return side of your Power Unit
’
s hydraulic circuit.
