Before starting the work, check the condition of the disc harrow, especially the condition of the working parts and bolted connections. NOTE! The correct procedure for mounting the shafts in the arm holders requires that the bolts be evenly tightened diagonally, so that the entire plane of the arm holders is adjacent to the plane of the shaft clamp profile. -

Hook Cylinder Fig. 5 Main frame with automatic wing locking mechanism. 4.4.2 Opening sequence for machines without chassis Before unfolding the folding wings of the machine, it is important to familiarise yourself with the opening sequence that allows you to do this correctly. 1. - Page 19 Fig. 6 Machine opening sequence: 1- lift the machine up to its maximum, 2- fold the machine wings into the "closed" position. 3. Once you have ensured that the hook of the hydraulic wing lock mechanism will allow the machine wings to be unlocked, you can proceed to open them fully (fig.7).

4. When opening the machine's wing arms, ensure that the ends of the arms are at a sufficient height to prevent them from catching the ground (fig. 9). Fig. 8 Machine opening sequence: opening the machine with special attention to the height of the arm ends from the ground. - Page 21 On the GAL disc harrow, the position of the individual working units must be preadjusted before starting work in the field. It is also necessary to level the machine longitudinally with the tractor's top link or drawbar turnbuckle and transversely with the right lower link hanger.

When working with the machine, it is also advisable to use an additional weight on the front of the tractor to enable more stable and comfortable working. Levelling the machine.
- Page 24 Machine levelled incorrectly:...
- Page 25 Levelling: If you notice an abnormality in the machine's level, screw or unscrew the end of the cylinder. Firstly, the lock nut is loosened with a size "50" spanner and then the cylinder end is adjusted with a size "41" spanner by placing the spanner on the end of the cylinder piston rod.

- Page 27 Irregularities during operation - pulling off the machine Machine operating correctly: Pulling the machine to the right side: If there is a situation of the machine pulling to the right side, the level of the machine should be checked first. If the machine is not levelled correctly, this can occur when the left side is horizontal and the right side is facing upwards, the cylinder on the right side should be rotated.

Page 29: Working Depth Of The Gal-K Disc Harrow
4.4.4 Working depth of the GAL-K disc harrow The working depth is determined by the position of the shaft, whose arms are adjustable by cylinders. To maintain a constant shaft position (working depth) during operation, clamps are fitted to the cylinder piston rods (fig. - Page 30 Once the required working depth has been established, the appropriate number of clamps must be taken from the holder on the shaft arm and then fitted to the piston rod of the cylinders. This ensures a constant working depth during operation. The number of clamps on both cylinders must always be equal.
-
Page 31: Opening Sequence Of The Machine On The Chassis
The working depth of the machine is set using pawls located at the piston rod of the cylinder. As more pawls are folded, the operation of the machine becomes shallower. In a configuration where none of the pawls are installed, the machine is in its greatest working depth configuration. - Page 32 Fig. 19 Location of pins preventing the machine wings from unfolding. NOTE! Remember to secure the machine wings against self-opening by means of safety pins each time the unit is folded. 3. Using the hydraulics, spread the arms of the machine horizontally until they are fully extended (fig.
- Page 33 Back view Side view Fig. 20 Unfolding the wings of the machine.
- Page 34 Back view Side view Fig. 21 Unfolding the wings of the machine to horizontal position. 4. The next step is to hydraulically unfold the open arms of the machine to a horizontal position (fig. 21, 22).
- Page 35 Back view Side view Fig. 22 View of the machine after unfolding. 5. Once the machine has been unfolded on the chassis, the alignment of the working shafts with respect to the machine must be carried out using hydraulic cylinders. The entire process is carried out using hydraulic cylinders that determine the height of the shafts and their angle of attack relative to the ground, and turnbuckles fitted to the machine's wing drawbars (fig.

Page 36: Adjusting The Working Depth And Setting The Correct Position For Machines With Chassis
4.4.6 Adjusting the working depth and setting the correct position for machines with chassis Once the machine has been unfolded, proceed with setting the working depth and levelling. First of all, the appropriate working depth must be determined using the hydraulic cylinders of the three-point linkage on which the disc harrows are suspended (item 1, fig. - Page 37 Fig. 25 Placement of turnbuckle on drawbar assembly; 1- turnbuckle. Levelling the machine is also possible thanks to the adjustment screws at the rear of the chassis. The vertical bolts (item 1, fig. 26) adjust the position of the disc harrow when the machine is folded.
- Page 38 fitted to the cylinder piston rods. The maximum permissible working depth is 12cm for discs Ø560mm. Once the required working depth has been established, the appropriate number of clamps must be taken from the holder on the shaft arm and then fitted to the piston rod of the cylinders.
- Page 39 Cylinder Fig. 29 The correct way to lift the machine when carrying out a turning manoeuvre. For machines with chassis, an option is available to purchase a valve block with electric control, which allows all the hydraulic sections (except the section responsible for folding/unfolding the machine wings) to be connected directly to the joystick control panel, which allows more convenient control of the machine's hydraulics and requires only two, free pairs of hydraulic connections on the tractor for its connection (fig.

Mode 3 - Deactivation of automatic brake function: To deactivate the automatic brake function (if towing a trailer by a non-two-wheel tractor or other type of vehicle): • Press the activation spool (as in the image on the right) until it is fully extended.
- Page 49 The activation spool automatically returns to its normal function position every time the pressure in the secondary line (SL) increases to its normal value. The valve's normal function mode is engaged each time the operator connects the two- line joint, starts the tractor engine and releases the parking brake. In this situation, all emergency functions are switched on.

NOTE! It is forbidden to work on a damaged machine caused by any event resulting in a broken, or deformed frame, shaft or other assembly of the machine! 5 Operation of the GAL-K disc harrow Everyday service Each time after work, the harrow should be thoroughly cleaned of soil and plant debris and the condition of the bolt and pin connections and the condition of the working elements and other parts should be inspected. - Page 55 However, if this is not possible, the condition of the protection should be checked from time to time and, if necessary, the rain-washed grease should be replenished. Operation of the GAL-K chassis Regular control of wheel pressure. If there is a significant loss of air from the tyres, check the air valve for leaks.
