Pre-Selector

The control box is installed in the driver's cabin. The function required
is preset with the pre-selector of the control box, and it is then
activated by means of the manual control lever or pedal respectively.
The tree spade is equipped with individual blade control as standard,
i.e. each blade can be controlled individually with toggle switches S1,
S2; S3 and S4.
Individual blade control is of particular advantage when soil conditions
are difficult.

The Operator must be a reliable person. Before commencing
production work, he or she must study these operating instructions
thoroughly.
The following safety instructions must be observed:
It is the operator's prime duty to ensure that any persons must stay
clear off the danger area. Special care must be taken that no one is
ever under the raised tree spade, or near the potential shearing
and pinching areas, or near the opened gate, near the spades or
near any hydraulic components.
Do not perform any manual work at the tree or shrub when it is
inside the tree spade. In particular, do not check the position of the
tree or shrub by hand or feet when it is inside the tree spade. Do
not bind the tree or shrub when it is near or inside the machine.
When sight is limited, an assistant should direct the operator by
hand signals.
Before starting to work with the tree spade, make sure the
hydraulic fittings and the bolts are properly tightened and are free
from any defects.
