Backhoe work
The bucket should be lowered at 45 to the
ground.
Use arm as a primary digging force to pull
bucket towards machine direction.
If there is mud adhered to bucket, move arm
and (or) bucket back and forth rapidly to get
rid of mud.
Note：
When arm is at 90° angle with arm
cylinder, and bucket cylinder is at 90°
angle with rocker arm, the max digging
force of arm and bucket can be
achieved.
The range for excavating with the arm
is from a 45 away from the machine to
a 30 angle toward the machine.
Machine can execute short-time intense
excavation: a pressurizing button is
presented on the top of the left control
lever. Press it down to increase system
pressure providing intense excavation
for 8 seconds.
