Krone Comprima F 155 service schedule

1. Park on level ground, disengage the PTO, stop the tractor engine, take the key out and apply the brakes.
2. Check the main gearbox oil level: take out the plug on the side. Oil must reach the hole. Top up through it if not.
3. Clean the machine.
4. Check the brakes work.
5. Clean the drawbar eye and bushing.
6. Check the chain lubrication dosing units and clean them if needed.

Tools: Spanner for the gearbox plug, Air line or brush, Rags

1. Disengage the PTO, stop the tractor engine, take the key out and apply the brakes.
2. Tighten the bolts and nuts on the machine and the drawbar bolts, to the torque table in the handbook.
3. Retighten the wheel nuts and check the tyre pressures.
4. Drain water from the air brake tanks if fitted.
5. New baler: also do these once after the first 10 hours, check the hoses for leaks and have the brake slack adjuster checked by a Krone dealer.

Tools: Torque wrench, Socket set, Tyre pressure gauge

1. Park the baler level on firm ground with the drawbar at the right height. Disengage the PTO, stop the tractor engine, take the key out and apply the brakes. The gearbox is behind the drawbar at the front.
2. Take out the plug from the inspection and filling hole on the side, then the drain plug underneath, and drain the oil into a tray.
3. Refit the drain plug.
4. Fill with SAE 90 GL4 through the side hole until it reaches the hole (about 2.00 L).
5. Refit the plug at the torque in the handbook.
6. First change at 50 hours on a new baler, then every 500 hours.

Tools: Drain tray (5 L), Spanners for the plugs, Torque wrench, Funnel, Gloves

1. Stop the tractor engine, take the key out and apply the brakes.
2. Change the filter on the central chain lubrication unit as the handbook shows.
3. Top up the reservoir with SAE 10W-40.
4. Clean the dosing units and check every hose reaches its chain.
5. Run the baler briefly and check oil reaches each chain.

Tools: Spanners, Funnel, Rags, Gloves

1. Lower the pick-up to working position, stop the tractor engine, take the key out and apply the brakes.
2. Take off the right-hand pick-up guard and clean the chains.
3. Pick-up main drive chain and pick-up drive chain: turn the spring nuts until spring lengths X1 and X2 are both 60 mm.
4. Check and adjust the intake, bale-forming conveyor, auger and starter roller chains as the handbook shows.
5. Refit the guard.

Tools: Spanners, Rule, Brush

1. Stop the tractor engine, take the key out and apply the brakes.
2. Clean rust off the net brake disc so the brake works evenly.
3. Fit the net roll on a cardboard core. Make sure the core sits the right way round and is dry, as damp cores go soft.
4. Run a tying cycle and check it works.
5. After the season, protect the brake disc from rust.

Tools: Emery cloth, Rags, Gloves

1. Disengage the PTO, stop the tractor engine, take the key out and apply the brakes.
2. Check the oil level in the main gearbox and the chain lubrication unit.
3. Tighten bolts and wheel nuts, check tyre pressures, and clean the drawbar eye.
4. Drain the air brake tanks if fitted.
5. Set the scrapers on the deflection shafts and the fixed deflection rolls (gap 0–0.5 mm). Do this once more after the first 500 bales on a new baler.
6. Look over the pick-up tines and replace any that are broken. No tine part number was found: check your handbook.
7. Grease every point on the lubrication chart with two strokes per nipple, and wipe off the excess.
8. Check the hydraulic hoses and electrical cables.
9. Run a tying cycle and check all functions.

Tools: Grease gun, Torque wrench, Tyre pressure gauge, Feeler gauges

1. Clean the baler and the drive chains.
2. Grease to the lubrication chart, including the PTO shaft and adjuster threads.
3. Retract the hydraulic rams as far as they go and grease the bare rods. Oil joints that have no grease nipple.
4. Drain the air brake tanks.
5. Touch up the paint, rust-protect bare metal and the net brake disc, and check all moving parts move freely.
6. Store dry, away from fertiliser and other corrosive things, with the tyres out of oil and sunlight.

Tools: Air line or brush, Grease gun, Oil can, Touch-up paint

1. Book the baler in with a Krone dealer to have the air tanks checked and the brake cylinders serviced.
