Work with bucket
The excavator is a multi-task machine capable of being fitted with
a multitude of special attachments to perform many types of work.
Only the simplest operations are described below.
Backhoe work
For digging work at a lower level than the machine is located.
90
When the angle between bucket cylinder and links, arm cylinder
90
and arm is set to 90 ° respectively, the working efficiency of each
cylinder will be at its maximum.
In case of digging, take advantage of this angle to improve the

work efficiency. When digging the useful movement of the arm is
30 ° forward and 45 ° rearward. There may be a little difference ac-
cording to digging depth. Do not use the cylinder up to its stroke
end, but only within this range.

Ditching work
Install a proper bucket for ditching. Place the machine over where
the ditch is to be to work effectively.
In case of a wide ditch, dig both sides in first, then the center area.

Loading work

Position the hauler so as to achieve a small slewing movement
and good visibility for the operator to work effectively.
Also load over the rear of the dump truck, rather than over the side,
as this makes the operator work easier and increases efficiency.
