Parking brake closes to implement brake
when draw up; Parking brake is free to
release braking when press down. The
parking brake is also used to be
emergency brake. When machine is
working, if urgent, pull up parking brake
button and then implement emergency
brake. When parking brake system errors
and air pressure in service brake loop is
lower than 0.4Mpa, parking brake
implements brake automatically. Wheel
loader implements emergency parking to
insure safety.
Pilot control lever
The device control levers are at the right
side of the seat. They are used to control
the working devices. The lever is used to
control the bucket and lift arm. The levers
are at the holding situation when they are
at the neutral position, which is the middle
position.
When the engine is working. The
bucket tilt up when you push the 29 left,
and the bucket tilt down when you push the
29 right
ripper rises when pull 22 backword, ripper
falls when pull 22 forward.
The lift arm falls when you push 30 forward,
the lift arm rises when you pull 30
backward.
The lift arm would be at the floating
situation when you push the lift arm lever
forward to the extreme position. When you
pull the lift arm lever back to the middle
position, the lift arm would be free from that
situation.
When the lift arm falls, push the lift
arm lever forward to the floating position,
then the lift arm would fall due to gravity,
meanwhile, the driver can do other
operations by his right hand (like put the
bucket flat), thus the operator can increase
the work efficiency.
When you do the sticking and spading
operation, push the lever to the floating
position, and then the bucket can float with
the ground, which can avoid the damage to
the ground.
When you do the spading operation,
make full use of the floating device of the
lift arm and self-flatted device of the bucket,
you can effectively reduce the work
strength and make the operation more
comfortable.
Warning: No matter what the situation that
the machine is in, make sure that there are
no obstacles and people around, under or
above the machine before you operate the
lift arm and bucket. Or else it may damage
the devices or hurt the people.
