MAINTENANCE107HOW TO PUT INTERNAL COMBUSTIONENGINE (I.C.E.) TRUCKS IN STORAGEExperience has taught that complications can arise as aresult of improper handling of trucks during periods ofstorage.The main areas of concern are engines, hydraulic compo-nents and truck batteries.I.C.E. powered trucks can best be protected by being op-erated for a short period of time each month.Before placing any truck in storage, you must choose anarea which is clean, dry and free from airborne contami-nates.Trucks powered by I.C.E. must be started and run at 700RPM until normal operating temperature is reached. Thiswill coat the internal engine components with a film of oiland rid the engine of built--up condensation.CAUTIONDo not shut down an engine before it reaches operat-ing temperature. Engine damage can occur.For safety and increased usable floor area, remove theforks and tag them with the truck serial number.Prior to operating a truck each month, make a visual in-spection for leaks or signs of deterioration. Take correc-tive action immediately. Also, check the fluid level in theradiator, hydraulic tank and brake master cylinder.All hydraulic cylinders must be cycled several times eachmonth to keep the seals active and to coat the interiorwalls with oil. Actuate each cylinder, in both directions, un-til it reaches the stops.To protect the tilt cylinder rods, park your trucks with themast tilted fully backward (cylinders retracted).When parked with the power off, actuate each controlhandle to relieve hydraulic pressure.CAUTIONMast are to be stored fully lowered to protect cylinderrods.Coat any exposed portion of all cylinder rods with fresh,high grade SAE 30 or 40 weight engine oil.Install blocks, front and rear, at the drive wheels whenparked -- DO NOT USE THE HAND BRAKE.Property of American Airlines
