zFill the fuel tank completely, lubricate and change oil.

zDisconnect the negative terminals of the battery and cover it, or remove it from the machine and store it separately.

zIf the ambient temperature is expected to drop below 0oC, add antifreeze to the radiator.

Removal from long term storage:

zApply oil to the engine valve and rocker arms, and examine the operating condition of the valves.

zRemove the oil filler pipe from the turbocharger oil inlet port, add 0.5-1L (0.13-0.26gal) of oil to the turbocharger, reinstall the oil filler pipe.

zChange the oil in engine oil pan.

zReplace all the filters.

zFlush the inside of the cooling system.
