CONTROLS
Auxiliary Hydraulic Lines
WARNING
¡
¡
¡
¡
¡
Oil may spurt out if caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.
• When removing plugs or
disconnecting hoses, release the
internal pressure before removing.
¡
¡
¡
¡
¡
Hydraulic fluid, tubes, fittings and
quick couplers can get hot when
running machine and attachments.
Be careful when connecting and
disconnecting quick couplers.
These lines deliver the hydraulic oil necessary
for operating the other attachments.
¡
Auxiliary hydraulic flow rate and rated
pressure:
Flow Rate ... CTL60: 68L/min (18.0 gal/min)
CTL70: 75L/min (19.8 gal/min)
CTL80: 88L/min (23.2 gal/min)
Rated Pressure ...... 20.6 Mpa (2987 psi)
Quick Couplers
Connecting: Remove dirt or debris from the
surface of both the male and female
couplers, and from the outside diameter of
the male coupler. Visually check the couplers
for corroding, cracking, damage or excessive
wear. If any of these conditions exist, the
coupler(s) must be replaced.
Install the male coupler into the female
coupler. Full connection is made when the
ball release sleeve slides forward on the
female coupler.
Disconnecting: Hold the male coupler.
Retract the sleeve on the female coupler until
the couplers disconnect.
Releasing the Residual Pressure
Connecting: Push the quick couplers tightly
together and hold for five seconds; the
pressure is automatically released as the
couplers are installed.
Disconnecting: Push the quick couplers
tightly together and hold for five seconds;
then retract the sleeve until the couplers
disconnect.
Connecting the Hydraulic Circuits
To connect the attachment hydraulic lines,
use the following procedures:
1. Connect the attachment hydraulic lines to
ports (a) and (b).
When fitted with a hydraulic breaker:
a. Connect the return circuit to port (b) and
the supply circuit to port (a).
b. Turn on the flow selector switch.
Refer to page 47 “Flow Selector Switch”.
Some attachments may have a case
drain, which needs to be the connected
to the small port (T).
2. When connecting is complete, purge air
from the hydraulic lines.
a. Start and run the engine at low idle with
no load for 10 minutes.
b. With the engine running at low idle,
operate the auxiliary hydraulics switch
repeatedly (approx. 10 times) to purge
air from the hydraulic lines.
c. Stop the engine and wait for more than
5 minutes until bubbles escape from the
hydraulic oil in the tank.
