Page 9: Operating Environment
OPERATING ENVIRONmENT 5 OPERATING ENVIRONmENT 5.1 INTENDED USE The purpose of a chipper is to produce chips from trees which are suitable to be fed into the chipper’s feed orifice based on their diameter and other measurements. The wood material must be clean. Dust, sand or soil quickly wear down the blades. -
Page 10: Principle Of Operation
The discharge chute directs the chip flow to the desired destination. 6.2 NO-STRESS fEATURE In Junkkari woodchipper there is always a no-stress feature. Purpose is to prevent chocking which can happen with big hard materials when tractor is not oversized. The idea is to set the certain RPM level for the disc, and if RPM goes below that, the feeding will stop. -

Page 15: Feeding Device Speed Adjustment
ADJUSTmENTS 10.2 fEEDING DEVICE SPEED ADJUSTmENT The rotational speed of the feed rollers in G/GT/GTC models chippers must be synchronised with the cutting speed of the blades. If the feed roller rotational speed is too high in relation to the blade cutting speed, the feed rollers will dig into the stems that are fed in the machine. -
Page 16: Operation
OPERATION 11 OPERATION The material to be chipped should be pre-treated where necessary. Large tree branches, roots and boughs should be removed to fit the wood into the feeding orifice. It is recommended that the wood be placed near the chipper to avoid carrying it long distances. -
