disposal of wood waste, twigs, barks, branch-wood and other above-ground
biomass or for manufacture of chips from aforesaid materials and also for disposal
of redundant timber, such as sticks, deals, pickets etc. This chipper is designed for
material loading while the tractor is standing on flat and compact surface. In front
of the loading chute there should be an area with minimum free space of about 5
m.
The chipper can dispose all these materials with diameter up to 160 mm or flat
boards and plates with thickness up to 60 mm .
These wooden pieces must be free of metal, glass and other similar objects. While
working, the chipper must be relatively levelled.
The chipper should be controlled and operated by two attendants who in turns load
materials to be chipped in a loading chute.
Not Allowed Use
The chipper is not allowed to be used for disposal of aforesaid materials with
foreign matters and objects, such as metal, steel binding bands, glass cullet, stony
debris, ceramics etc.
It is not possible to use the chipper in the presence of unauthorised persons who
may stand or move in direction of discharge ducting. At work in residential zones
use the machine in accordance with regulations of the local authorities to avoid
disturbing of local inhabitants (noise level). While chipping, it is not allowed to
enter the area of ejected flying wooden chips.
On hilly terrain its loading chute height should not be lower than 600 mm.
It is not allowed to stand on higher spots around the machine while loading
materials into the chute.
