CLG835H
Brake system
At short time of starting the machine, the service
brake low pressure alarm light flashes and the
alarm buzzer sounds. Because oil pressure in
the accumulator of service brake circuit is still
lower than the alarm pressure (11MPa\1595psi)
at this time, and the alarm will stop automatically
as pressure in the accumulator is higher than the
alarm pressure. Press down the emergency
brake button only after the alarm stops. During
operation, if the system is faulty, resulting in oil
pressure in the accumulator of service brake
circuit lower than 11MPa\1595psi, the service
brake low pressure alarm light flashes and the
alarm buzzer sounds. At this time, stop operation
and park the vehicle for inspection. During
inspection, stop the machine on level ground and
pull the emergency brake button.
When press down the emergency brake button,
the solenoid valve is powered on, valve port is
open, the pressure of oil outlet is
16MPa\2320psi, high pressure stored in the
accumulator of parking & emergency brake
circuit enters into parking brake cylinder via
emergency brake solenoid valve to release the
parking brake. At the moment of pressing down
the emergency brake button, the parking &
emergency brake low pressure alarm light
flashes. Because oil pressure in the parking
brake circuit is still lower than the alarm pressure
(11MPa\ 1595psi) at this time. The machine can
be started only when the emergency brake low
pressure alarm light is off. When pull the
emergency brake button, the solenoid valve is
powered off, hydraulic oil in the parking brake
cylinder flows back to oil tank via emergency
brake solenoid valve and the parking brake is
locked. During operation, if the parking &
emergency brake circuit is faulty, resulting in oil
pressure in the accumulator BR3 lower than
11MPa\1595psi, the emergency brake low
pressure alarm light flashes. At this time, stop
operation and park the vehicle for inspection.
During inspection, stop the machine on level
ground, pull the emergency brake button and
chock the wheels with blocks to prevent the
machine from moving.
If the service brake low pressure alarm fails and
the system is faulty, which results in oil pressure
in the accumulator of service brake circuit lower
than 7MPa\1015psi, the clutch on/off switch of
emergency brake in the system cuts off the
power automatically to engage the transmission
in N position. Simultaneously, the solenoid valve
is powered off, hydraulic oil in the parking brake
cylinder flows back to oil tank via emergency
brake solenoid valve so that the parking brake is
locked and the emergency parking of loader is
achieved.
When the shift control lever is in forward or
backward I & II position during driving, do not
disconnect the clutch on/off switch eas-
ily,otherwise, the brake and power train sys-
tem may be damaged. When the machine is
in operation at the upslope or downslope of
rough road and the brake is applied, the func-
tion can be selected in order to ensure safe
driving.
Unless in emergency, do not apply parking &
emergency brake when the machine is run-
ning. Applying parking & emergency brake in
normal operation will cause serious damage
to the brake and power train system.
