Operating guide
1. Backhoe work
Backhoe is suitable for digging job
which position is lower than the
machine..
Bucket will have the biggest digging
force if the machine is in the state
that bucket cylinder and linkage, arm
cylinder and arm are all at 90
o.
The effective use of the angle will
optimize the work efficiency.
Digging range of arm is 45
o
outward
and 30 o inward.
Please operate the arm in proper
digging range as possible as you can,
do not pull or push the cylinder to the
end of its moving distance.
Attention: before digging on hard rocky ground, please break the ground
by other means first to ease off damage and save cost.
2. Loading work
In narrow working site, it will have
better working efficiency to park the
dumping truck in the place that
excavator operator can see it clearly.
It is more convenience and higher
efficiency to load a dumping truck
from rear part then from sides.
