Lely Welger RP 405 / RP 435 / RP 505 / RP 535 fixed-chamber round balers service schedule

1. Look at the reservoir (visual check) before starting the day.
2. If low, clean around the cap first, unscrew it, and fill with clean oil through the filling filter up to the max mark.
3. If it ran dry, bleed the system: take the lines off the lubrication points, run the pump until oil flows from each line with no bubbles, collect the oil, and refit the lines.

Tools: Funnel, Clean cloth

1. Stop the engine, take the key out and wait for everything to stop. Make sure the tail gate is safe.
2. Grease the drive shaft, tail gate hinge, locking hooks on both sides, the rollers on the locking device, cutting rotor on both sides and castors (if fitted).
3. Give the lubricant metering device (roller lubrication) 2 strokes of the manual grease gun. Do not use a compressed air grease gun on it.

Tools: Grease gun (hand), Rag

1. Retighten all fastening screws, wheel nuts (460 N·m) and drawbar screws and nuts, also the ones inside the machine.
2. Do not touch the adjusting screws on the twine guiding or the net brake.

Tools: Spanners, Torque wrench

1. Run the machine briefly to warm the oil, then stop the engine and take the key out.
2. Drain the oil and refill with 1.7 L of SAE 90 API GL-5 gear oil.
3. Check the level on the dipstick or at the overflow hole.

Tools: Drain tray, Spanner

1. Dismantle, clean and grease the Belleville springs of the locking hooks. Do not change the sensor setting.
2. Make the moving parts of the net tying unit or twine tying unit run smoothly (lubricant D machine oil in the handbook table).
3. Grease the tail gate lock hydraulic cylinder (both sides), the star ratchet in the pick-up drive (left side) and the brakes (both sides). Lightly grease the chafe marks on the twine eyes.
4. Machines with XtraCut 17 or XtraCut 25 cutting device: grease the knife levers 3 weeks after first commissioning, then once per season.

Tools: Grease gun, Spanners

1. On the pick-up and cutting device drive chains, loosen the chain tensioning blocks in their slots, readjust and retighten them.
2. The other chains have spring tension. Adjust, then lock the nut again.
3. If a chain cannot be tensioned any more, shorten it by one link (fit a cranked link if needed). New chains stretch quickly, so tension them slightly tighter at first.

Tools: Spanners

1. Open and secure the tail gate hydraulically and mechanically. Wear gloves because the knives are sharp.
2. Take the knives out, regrind them and refit them. Park any blind blades and removed knives behind the left casing door, secured with a cotter pin.
3. Do not strike installed knives from underneath because the magnets in the holders can be damaged. Pacemaker wearers must keep away from the magnets.

Tools: Gloves, Knife holder tools, Grinder

1. With the lever pointing up, the brake disk must not turn by hand. If it does, loosen the screw on the lever and tighten the milled nut until the brake linings fully touch the disk, then retighten.
2. If the lining wears on one side only, loosen the lock nut and wind the screw in slightly until the linings are parallel.
3. The net tensioner shock absorber on the left: set the two wing nuts hand tight at the top and bottom end positions so the tensioner can just move by hand. Do not reach into the net knife area.

Tools: Spanners, Gloves

1. Put the baler on level ground. Take the twine and net out and clear straw from the machine.
2. Unplug the control box and keep it dry and at room temperature.
3. Remove the cutting device knives, regrind them and refit them. Grease the tying mechanism and all the bearings.
4. Lightly grease the baling chamber surface with something that harms neither the environment nor the fodder, such as rape oil.
5. Check and adjust the tyre pressures.

Tools: Grinder, Grease gun, Tyre gauge

1. Switch off the PTO, stop the engine, take the key out and find what caused the overload.
2. Fit a new original shear bolt with its nut. Do not restart until the cause is removed.

Tools: Spanners
