Description
The object of the Safety Restraint Bar is to prevent
accidental operation of the hydraulic controls whilst the
operator is not in his seat and ready to drive or manipulate
the machine. To achieve this a cam is connected to the R.H.
end of the restraint bar (Loader Joystick side), which
operates an electrical switch in the Pressure Reducing
Solenoid Valve circuit. The Pressure Reducing Solenoid
Valve dumps hydraulic pressure to the tank, preventing drive
and operation controls from working.
Removal
Ensure that all hydraulic pressure is removed from the
system.
Disconnect and plug all hydraulic lines to the two joysticks at
B
and
C
. Break the electrical connections to the joysticks at
the plugs.
