OPERATION & MAINTENANCE MANUAL SWE50E/SWE60E/SWE70E/SWE80E9/SWE100
3.10.12 Work
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 degree angle with
arm cylinder, and bucket cylinder is
at 90 degree angle with bucket link,
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. Pressing it
allow system pressure to rise and
provide intense excavation for 8
seconds.
Ditching work
To excavate a straight ditch, set track parallel
to ditch. Excavate to desired depth, then travel
machine backward to proceed excavating
based on.
Note
Avoid suddenly stopped when boom is
lowered. Or the compact loading will
damage excavator
When operating the arm, the hydraulic
cylinder should be avoided to the end
in order to prevent to damage
hydraulic cylinder.
Avoid bucket bump track
When the machine dig deep trenches,
Avoid bumping the hose or the bucket
or boom with the ground.
