Adjustment of chipping device
Optimal operation of the chipping device requires right setting of clearance
between the blade and the opposite cutting edge. This distance should be set
(see the following figure) and checked after fitting the ground blades, then it
grows with their wear and chipped branches may be squeezed between the
blade and the opposite edge. It brings deterioration in quality of chipping.
Pay attention also to the blades exchange. In such case set the given
clearance bigger to avoid damage of a new blade and its opposite cutting
edge.
Recommendation: Check out conditions of blades every 40 operating hours.
Regrind blade edges if they are found blunt.
Jointing elements (bolts and nuts) should be replaced together with
The blades exchange. Safety nuts should be used only once, since
they lose their self-locking properties if used repeatedly.
NOSTRESS System – Speed Regulation
This system is intended for overload protection of the combustion engine
consisting of an electronic control unit and a speed sensor installed on the
rotor shaft.
NOSTRESS ON – the chipper works with automatic regulation of loading (no
engine overloading).
NOSTRESS OFF – the chipper works without automatic regulation of loading.
This way of operation is recommended only in case of a failure of the control
unit.
