  • Page 8: Work Safety Instructions

    Work Safety Instructions Utilisation This chipper, being coupled with a tractor three-point hitch, is designed for 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. The chipper can dispose all these materials with diameter up to 160 mm or flat boards and plates with thickness up to 60 mm.
  • Page 9 concerned controller in infeed direction this machine must stop loading materials and by its next pushing the loading rolls should turn back while being under permanent pressure (pushing). The controller frame have to be advanced in front of the hinged loading chute edge so that the attendant stops the loading rolls, or let them turn back, at pushing by using parts other than hands (e.g.
  • Page 10 While working the chipper should rest on the ground. Keep this machine beyond children's and unauthorised person's reach. Avoid their attendance while chipping. When using the chipper without any container or closed bin, keep anybody beyond the area where chips are being thrown. When using the chipper with such a bin, never look inside if the chipper is still working.
  • Page 11 While chipping the operator is obliged:  to use only such a chipper which is in optimal operating condition, not damaged through transport, storage of from previous operation,  to check functions of all controls and safety elements, particularly the controller frame, before putting the chipper into operation, ...

    Emergency STOP button blocks loading immediately – similar function as that of the safety frame. Controls Ignition box – used for supply and control of the safety circuit. CAUTION: Despite the fact that this machine is not equipped with any driving engine, its ignition key, analogously to engine starting, must be set in the START position and afterwards in the RUN position.

  • Page 19: Use

    Controller of loading speed - installed under a hinged part of the loading chute Change of loading roll speed Speed regulation in range from 0 to 40 m/min Emergency STOP button blocks loading immediately – similar function as that of the safety frame.
  • Page 20  locking of hinged part of loading chute in transport position  fitting of triangular symbol for slowly vehicles on framing It is strictly forbidden to transport the chipper with the PTO shaft on. It is not allowed to transport any objects or loads on the chipper. Never couple another machine or implement to the chipper.

  • Page 21: Storage

    Storage Store the chipper always in a dry shelter to protect it against weather effects. During storage keep the switch key separately. Keep the stored machine beyond unauthorised persons reach. Before storage clean all parts of the machine. For cleaning use pressure water. Should the water be in the chipping device space, wipe it off and let it dry.
  • Page 22 Avoid spillage at filling hydraulic oil. Use always a proper filling funnel. If any oil is spilled or overflowed then wipe off the spots immediately. Do not use petrol or similar inflammable matters as a cleaning agent. It is strictly forbidden to do any technical changes on the machine without any prior approval of the manufacturer in writing.

  • Page 23: Coupling To Tractors

    Coupling to Tractors This chipper can be coupled to a tractor which is equipped with a three-point hitch, category I or II and a PTO shaft. This hitch coupling can be done from outside by means of locking pins, Ø 27 mm for the category II or Ø 22 mm for the category I. The chipper is height-adjustable (according to tractor tires size) when inserting pins in other holes, see following figure.

  • Page 24: Putting Into Operation

    When coupling the chipper to a tractor just let the lower drawbars go down in a similar height as the coupling pins are. Go back slowly with the tractor to the chipper hinge. While coupling the chipper no person is allowed to stand between the chipper and the tractor Lock the lower drawbars by means of locking pins in the chipper hinge.

  • Page 25: Chipping

    Carry out a functional check of the safety frame of the loading chute. Set the lever in the infeed position and the loading rolls start turning (loading). By first pushing the frame the rolls should stop loading immediately (EMERGENCY STOP), the next pushing behind the chute edge (D) brings their reverse turning.
  • Page 26 When loading materials and during operation of the chipper the attendant should always stand in the attendant's place, see fig. Having turned the chipping device on wait for speed stabilization. With that you may soever increase or reduce the tractor PTO shaft speed. For correct chipping functions it is necessary if the tractor PTO shaft speed is 540 rpm(1000 rpm).
  • Page 27 Be careful while loading since materials may unexpectedly move in unwished directions. In case of two attendants it is necessary to make simple signals clear before working. During operation it is not easy to make any agreements because of operating noise. Observe the working area.
  • Page 28 Blunt blades are evident on chipped edges which are not  clean but broken. The optionally used breaker for crushing brings increased  costs for energy consumption. The breaker should not be used for small and short  wooden pieces, leaved or coniferous branch wood (with low weight) which may bring fouling due to shortage of woody mass.

  • Page 29: Putting Out Of Operation

    Putting out of Operation If you want to stop chipping: In case of loaded material wait for emptying of the loading chute. Wait for emptying of the discharge duct. Turn the tractor PTO shaft off. Warning! The cardan shaft is equipped with a freewheel clutch. When turned off, the rotor of the chipping device runs out –...

  • Page 34: Blade Grinding

    Blade Grinding Blades, fitted on the chipping wheel, are double-sided, i.e. reversible if one side is blunt. Blades edge regrinding requires high demands for keeping cutting edge shape. While grinding it is necessary to keep its optimal geometry, see following figure. Proper shapes prolong blade service life.

  • Page 35: Chipping Adjustment

    Max. wear/grinding of cutting edge Chipping Adjustment Optimal operation of the chipping device requires proper setting of a clearance between the blade and the opposite cutting edge. This distance should be set (see following figure) and checked after fitting ground blades, then it grows with their wear and chipped branches may be squeezed between the blade and the opposite edge.
