1. Set the selector to manual and start the pump; seen from the fan cover the motor should turn clockwise.
2. Press Close rolls and slowly turn the relief valve clockwise until the black needle reads 4.0 MPa.
3. Set the green low-pressure needle to 3.5 MPa and the red high-pressure needle to 4.0 MPa; the working pressure stays in this band.
4. Adjust the feed pressure-reducing valve to 1.5–2.0 MPa.
5. Try open/close rolls, feeder on/off and gate open/close; check every movement completes and nothing leaks.

Note: Factory setting 3.5–4.0 MPa; adjust to suit the material.

1. Loosen the adjustable handle, turn the sleeve a few turns anticlockwise and centre the slide block.
2. Close the rolls in manual mode so they touch fully, then tighten the sleeve clockwise by hand.
3. Open the rolls and turn both sleeves clockwise by the same amount: 0.1 mm per division, 2 mm per turn.
4. Close the rolls, check both ends with a feeler gauge, and lock the handle when they match.
5. While running, fine-tune with the slide blocks: for thicker flakes loosen the upper screw and tighten the lower one, the reverse for thinner. Adjust both sides together and take samples as you go.

1. With the rolls closed, reach in through the middle door and loosen the fixing screws and the adjusting-screw nuts on both sides.
2. Turn the adjusting screws to set a scraper-to-roll gap of 0.1–0.2 mm.
3. Tighten the nuts and fixing screws, then open the rolls.
4. When a worn scraper becomes too narrow, move it to the spare holes below.

1. Set the working roll gap first, then stop the mill.
2. With the rolls closed, set the cheek plates 0.2–0.3 mm from the roll surface.
3. Fix them in place, then open the rolls.

1. Connect the external supply and return ports to mains or a recirculating water system.
2. Open the inlet valve and check the lines for leaks.
3. Before starting the roll motors, make sure the rotary joints turn freely and are undamaged.
4. Grease the rotary joints every 1–3 months with Mobil grease HP (NLGI 2).

1. Fitting: clean the pulley bore, the bush inside and out and the screws with petrol; surfaces must be clean and dry.
2. Fit the key in the shaft keyway, slide the pulley on, then push the bush in over the key (tap the large face lightly with a soft mallet if needed).
3. Line up the holes, run the screws (with washers) in evenly and tighten them alternately to the specified torque. Never force them.
4. Retighten to torque after 0.5–1 h of running.
5. Removal: take out the fitting screws, screw them into the bush’s jacking holes and tighten alternately until the bush releases; remove the bush first, then the pulley.

1. Clear any foreign material, run a no-load trial and turn on the cooling water.
2. Start the main motors first; once they run smoothly, start the pump.
3. Select automatic and press Program start: rolls close → gate opens → feed roll starts → pump stops.
4. Take samples from both ends and the middle at intervals to check thickness and gelatinisation; adjust the slide blocks for thickness, steam and feed rate for gelatinisation.
5. Program stop sequence: feed roll stops → gate closes → rolls open.
