Pöttinger NOVACAT 302 service schedule

1. Stop the PTO and engine, take the key out and wait until the discs have stopped.
2. Grease the cross joints and profile tubes.
3. Check the guards are complete, turn freely and are held by their chains.
4. Check the overload clutch slips rather than being seized after storage. Do not change its setting (1,500 Nm).

Tools: Grease gun, Rag

1. Lower the mower, disengage the PTO, stop the tractor engine and take the key out. Wait until every disc has stopped.
2. Look at every blade. Uneven wear between the two blades on a disc unbalances it: replace both.
3. Measure the blade bolts. Replace a bolt under 15 mm diameter or worn at the bottom.
4. Replace a blade holder when wear reaches the edge of the hole.
5. To change a blade: put the lever between the disc and blade holder at a right angle to the ground (position A) and swing it level with the disc (position B) to push the holder down.
6. Take the blade off, clean crop and dirt from round the bolt and out of the hole, and check the blade's sides are not bent.
7. Fit the new blade with the same R or L marking, its arrow matching the disc's rotation. Check it sits between the bolt and holder, then swing the lever back and take it out.
8. Put the lever back in its bracket on the frame.
9. Retighten all bolts after the first hours of use, especially the blade bolt connections.

Tools: Pöttinger blade-change lever (kept on the frame), Vernier caliper, Gloves

1. Stop the PTO and engine, take the key out and wait until the discs and rotor have stopped.
2. ED tine conditioner: check the V-belt tension. It is right when the marker point is flush with the shim.
3. ED: check the tine fixings for wear and replace worn tines, bolts or slotted spring pins. Use position Z2 (tines turned 180°) if crop wraps the rotor.
4. RC roller conditioner: grease the drive every 50 hours.
5. RC: check the drive belt and tension pulley. The pulley must run parallel to the belt, especially after first use or any change to the drive.
6. Replace damaged or worn belts as a complete set.

Tools: Grease gun, Spanners, Torch

1. Do it with the oil warm. Stop the PTO and engine, take the key out and wait until the discs have stopped. Park on firm, level ground.
2. Tilt the cutterbar as far as it goes, remove the drain plug and let it drain fully. It takes a while.
3. Refit the drain plug.
4. Lift one side of the bar and prop the whole length so it is exactly level across its width.
5. Fill with the right amount of SAE 90 through the filler.
6. Leave it about 15 minutes, then check: the oil should reach the lower edge of the level screw marked OIL LEVEL. Add only what is missing.
7. Dispose of the old oil properly.

Tools: Drain tray, Spanners, Stand or prop for the cutterbar, Funnel, Spirit level

1. Stop the PTO and engine, take the key out and wait until the discs have stopped. Warm oil drains better.
2. Remove the drain plug of each angular gear and let the oil run out.
3. Refit the drain plugs and fill with SAE 90: 1.25 L in angular gear 1 and 0.8 L in angular gear 2.
4. Check the level at the level plug and refit it.

Tools: Drain tray, Spanners, Funnel

1. Clean the machine thoroughly. Keep the pressure washer off bearings and hydraulic parts.
2. Change or top up the gear oil.
3. Grease all points on the lubrication chart and run the machine briefly.
4. Protect bare metal against rust and grease the ram rods.
5. Store it under cover.

Tools: Pressure washer, Grease gun, Rust preventer
