Type FZ 560 T-M: Face shield for attendance of hydraulic distributor. Controls This stump cutter can be operated by means of controls in the tractor cab through the three-point linkage, see instructions for the PTO shaft and in the tractor manual.
- Page 17 Type FZ 560 T-M: Cutting head guard up / down Jib control: up / down / right / left Cutting head suspension forward / backward Common Cutter Controls Flow limiter installed on the hydraulic cylinder for jib control. This limiter is preset by the manufacturer and further (contingent) readjustment can be done according to the tractor being actually used.
- Page 18 It is intended for reduction of oil flow going from the tractor into the cutter hydraulic system. This reduction is limited by actual capacity of the tractor oil pump. Transport Safety This stump cutter is delivered completely mounted and ready to use. It is equipped with a supporting feet frame intended for easier putting the machine aside on flat surface.
- Page 19 After detachment of the cutter its supporting feet must be extruded properly and locked against loosening. This supporting frame is designed for keeping stability after putting the cutter aside. Cardan Shaft Adjustment Before use it is necessary to check up cardan shaft adjustment as to its proper length. The cardan shaft length must be always adapted to the given tractor type.
- Page 20 Storage Store the stump cutter always in dry (sheltered) space to protect it against weather effects. Keep the stored machine beyond unauthorised person's reach. Before storage clean all parts of the machine. Use pressure water for cleaning. Remove any spilled oil immediately and wipe off all oily spots. Exchange all damaged or worn parts.
- Page 21 by means of connecting pins, ∅ 27 mm. For the category I: attachment into a fork by means of a connecting pin, ∅ 22 mm. According to an actual tractor tires size the connecting pins can be inserted into holes in two different heights.
- Page 22 Let the bottom draw rods sink until they are levelled with the connecting pins. Drive carefully back to the cutter hinge. While going back and coupling, nobody is allowed to stand between the cutter and the tractor. Attach the bottom draw rods of the three-point linkage and lock its pins by cotters or put the pin through the draw rod ball.
- Page 23 • Put the rear guard down to cover the cutting head properly. • When the cutter is properly coupled to the tractor, start the tractor and then turn on its PTO shaft which should run up gradually – increase shaft speed slowly up to its required/rated level.
- Page 24 The cutter hydraulic hoses, respectively their quick-couplers, are colour-coded. The coloured cutter coupler should be connected to the tractor pressure line and the white-coded coupler is to be connected to the tractor hydraulic return line. The yellow-coded coupler should be connected to opposite couplers marked 3-4 or 4-5, see fig.
- Page 25 Set the cutter onto the stump, start cutting in a swinging way and take individual stump layers continuously off. Depth of individual cut should be about 20 mm, less at start. Check out proper attachment/position of the rear guard. Avoid any cutting if there can be some foreign matters and objects, such as metal, glass cullet, stony debris, ceramics etc.
