If forage harvester is to be stored for some time (during the winter months), engine metal parts must be protected from corrosion and the fuel system must be protected from gummy deposits.

Protect engine, fuel system etc. as follows:

Thoroughly clean outside of engine with a safe solvent.

CAUTION: Do not use petrol!

Drain, flush and refill cooling system with fresh coolant every two years (refer to Section "Fuel, Lubricants, Coolant and Capacities").

IMPORTANT: Use only John Deere COOL-GARD ™ in the cooling system, independent of the season.

Swing rotary radiator screen away and carefully clean radiator fins, using compressed air or a weak water jet.

Drain engine oil and replace filter element. Drain oil when still warm. Refill crankcase with oil of specified quality and viscosity. Operate engine for a few minutes before adding rust inhibitor.

To protect engine and fuel system, use the rust inhibitor available from your John Deere dealer. The rust inhibitor set includes one can of rust inhibitor, masking tape and protective caps to cover engine openings.

Add rust inhibitor as follows:

Add 650 cm ³ (40 in. ³ ) of rust inhibitor to engine oil and run engine for a few minutes.

NOTE: This engine oil can be used again at the beginning of the next season for approx. 20-25 operating hours. Then drain the oil and refill crankcase with fresh engine oil of specified quality and viscosity.

Drain hydraulic oil reservoir and fill with fresh oil of specified quality. Add approx. 50 cm ³ (3.05 in. ³ ) of rust inhibitor.

Drain fuel tank and pour 150 cm ³ (9.2 in. ³ ) of rust inhibitor into empty tank. Add 10 L (2.6 U.S. gal) of fuel. Start engine and run at fast idle for 15-20 minutes to distribute the mixture in the complete fuel system.

With the engine running, operate all hydraulic functions several times.

Stop the engine and allow it to cool for approx. 15-20 minutes.

Remove fuse (3F19). Remove plug of intake manifold or connecting pipe of starting aid adapter and inject approx. 35 cm ³ (2 in. ³ ) of rust inhibitor per cylinder into this opening. At the same time crank engine with starting motor.

Do not start engine after rust inhibitor has been added.

Furthermore, use rust inhibitor as follows:

Disconnect turbocharger air intake line and inject 90 cm ³ (3.04 fl.oz.) of rust inhibitor into turbocharger intake side. Connect and tighten air intake line.

Disconnect turbocharger exhaust line and inject 90 cm ³ (3.04 fl.oz.) of rust inhibitor into turbocharger outlet side. Connect and tighten exhaust line.

IMPORTANT: Rust inhibitor agents evaporate very easily. For this reason, seal all openings after the inhibitor has been added. Also keep the inhibitor container closed at all times.

Fill the fuel tank completely.

Remove and clean battery. Store in a cool, dry place where they will not freeze. Charge batteries every three months to avoid damage to the plates.

Seal all openings with plugs or greaseproof paper. Cover muffler opening.

Slacken drive belt. Place strips of strong paper between fan belt and pulleys to prevent sticking.

Thoroughly clean engine and spray with anti-rust fluid; then cover engine with a tight-fitting, waterproof tarpaulin.
