IMPORTANT: When moving and working on public roads, the traffic rules
and regulations must be adhered to.
When driving, the tree spade should be in the lowest possible
position.
When digging, it might happen that a stone gets caught between
two blades and the blades get bent. This causes tremendous
tension in the steel blade. Do not try to release the stone by
means of a crow bar or other tools.
Place the digging head again into the planting hole and retract the
blades. Thereby the stone will come loose and the blades which
got a high degree of bending strength will regain their former
shape. After that the root ball can be dug again.
4.3 Releasing the Tree
When transplanting, or when placing the tree in a basket, lower the tree spade by
means of the lift arms, retract spad
es (function 3 “blades” , control valve “up”) and
retract scrapers (function 4 “scrapers”, control valve “up”); then unlock gate (function 1
"gate lock", control valve "unlock") and open gate (function 2 "gate", control valve
"open").
When the work has b
een finished, set the rotary switch in “off”-position (function 0).
