OPERATION
Figure 4.3 - Installed Couplers
the skid steer chipper is equipped to attach to flush face
couplers (Figure 4.3). the chipper is shipped with -12 sized
hydraulic couplers fitted on the hoses. a tie wrap is used to
indicate the pressure line. Be sure to connect the hydraulic
hoses to the proper ports.
if the skid steer is fitted with anything other than -12 sized
flush face couplers on the main lines, it will be necessary
to replace the couplers supplied with the chipper.
the chippers are also equipped with a case drain hose. the
case drain is used to eliminate pressure on the chipper’s
hydraulic motor. the motor is rated for 250 to 300 psi of
back pressure.
Most high flow skid steer loaders are equipped with a case drain
line. Standard flow skid steer loaders typically are not.
if the
back pressure is over 300 psi, a case drain line will have
to be added. contact your skid steer dealer for details.
To connecT:
Before connecting, make sure to relieve the hydraulic
pressure in the skid steer using the skid steer system.
remove dirt and debris from the surface of the couplers.
visually check the couplers for damage; replace if
damage is found.
install the male coupler into the female coupler. Full
connection is made when the ball release sleeve slides
forward on the female coupler.
turn the sleeve so that it is rotated away from the lock-
ing pin to prevent accidental disconnection.
repeat the procedure for all hoses, including the
smaller case drain hose.
To disconnecT:
relieve the hydraulic pressure in the skid steer using
the skid steer system.
rotate the ball sleeve so the grooves are aligned with
the pins in the female coupler.
retract the sleeve on the female coupler until the
couplers disconnect.
repeat the procedure for all hoses.
