LONG TERM STORAGE OPERATION LONG TERM STORAGE 0. BEFORE STORAGE 0. NOTICE To protect the cylinder piston rod when the machine is not being used, set the work equipment in the posture shown in the diagram. (This prevents rusting of the cylinder rod.) When putting the machine in storage for a long time, do as fol- lows. Clean and wash all parts, then store the machine indoors. If the machine has to be stored outdoors, select level ground and cover the machine with a sheet. Completely fill the fuel tank, lubricate and change the oil before storage. Apply a thin coat of grease to the metal surface of the hydraulic piston rods.
Disconnect the negative terminals of the battery and cover it or remove it from the machine and store it sepa- rately. Komatsu genuine Super Coolant (AF-ACL) is added to the cooling water, so there is no need to change the density for temperatures above -10єC (14єF). If the temperature goes below -10єC (14єF), adjust the density. For details, see "Cooling System Coolant - Clean/Change ( 4-21 )". Lock each control lever and pedal with the lock lever and pedal lock. Set the stop valve to the "lock" position on machines ready for attachments. Install the blind plugs to the elbows.
Set the selector valve on the machines which can install attachments to the "Crusher or general attachment" position. DURING STORAGE 0. If it is unavoidably necessary to carry out the rust-preventive operation while the machine is indoors, open the doors and windows to improve ventilation and prevent gas poisoning. coated over movable parts and component surfaces. At the same time, also charge the battery. For machines equipped with an air conditioner, run the air conditioner. Rotate the tracks. AFTER STORAGE 0. NOTICE If the machine is to be used when the monthly rust prevention operation has not been carried out, please contact your Komatsu distributor.
When using the machine after long-term storage, do as follows before using it. Wipe off the grease from the hydraulic cylinder rods. Add oil and grease to all places. When a machine is stored for a long period, moisture in the air will get into the oil. Check the oil before and after starting the engine. If there is water in the oil, change the oil. A plastic fuel tank is used, so never use trichloroethylene when washing it. Washing in trichloroethylene will reduce the strength of the fuel tank. 3-94 WARNING
