RELIEVING HYDRAULIC SYSTEM PRESSURE - CONTINUED
1.
Introduction.
a.
Hydraulic oil can remain under pressure in hydraulic system even after engine has been shut down and hydraulic
pump has stopped.
b.
It is important to relieve this pressure before disconnecting any hydraulic line or performing hydraulic system ser-
vice.
2.
Relieving Hydraulic System Pressure.
a.
Park machine on level ground.
b.
Lower work tool to the ground.
c.
Engage parking brake.
d.
If locked, press bottom of hydraulic lockout (IMPLEMENT DISABLE) switch to unlock hydraulic controls.
CAU T I ON
Stopping engine immediately after it has been operating under a load can result in over heating and accel-
erated wear of engine components. Refer to page 0005 00-7.
e.
Shut down engine.
f.
Turn engine start switch to ON position without starting engine.
g.
Move loader control joystick and auxiliary hydraulic control lever through all positions. This will relieve any pres-
sure that may be present in hydraulic system.
3.
Relieving Brake System Pressure.
a.
Park machine on level ground.
b.
Lower work tool to the ground.
c.
Shut down engine.
d.
Engage parking brake.
e.
Turn engine start switch to ON position.
f.
Depress brake pedal 30 times, pausing 2 seconds between each application.
g.
Turn engine start switch to OFF position.
QUICK COUPLER OPERATION
0005 00
1.
Introduction.
a.
The quick coupler design allows operator to connect loader quick coupler to work tools.
b.
The MP bucket also requires hydraulic connections for its operation.
c.
The following instructions apply to both work tools.
d.
Relieve hydraulic pressure (see step 2 above).
e.
Disconnect quick disconnects, plug ends into each other and rotate, lay them on top of MP bucket, and install pro-
tective caps.
f.
Turn engine start switch to ON position and start engine.
