LONG TERM STORAGE 3.6 LONG TERM STORAGE 3.6.1 BEFORE STORAGE IMPORTANT To protect the hydraulic cylinder piston rod while in storage, keep the work equipment in the posture shown at right. (This prevents rust from developing on the piston rod) When keeping in long-term storage (more than one month), store as follows. 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. Fill the fuel tank to prevent moisture from accumulating. 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. Lock each control lever and pedal with the safety lock lever and pedal lock. Set the selector valve on the machines which can install attachments to the “Crusher or general attachment“ po- sition. 3.6.2 DURING STORAGE When it is necessary to perform the rust-preventive operation while the machine is indoors, open the doors and windows to improve ventilation and prevent gas poisoning. During storage, always operate the machine once a month so that a new film of oil will be coated over movable parts and component surfaces. At the same time, also charge the battery.
When operating the work equipment, wipe off all the grease from the hydraulic cylinder rod. 3.6.3 AFTER STORAGE IMPORTANT If the machine has been stored without the monthly rust prevention operation, consult your Komatsu Dealer for service. 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 at all lubrication points. When the machine is stored for a long period, moisture in the air can contaminate the oil over time. Check the oil for presence of water before and after starting the engine. If there is water in the oil, change the oil.
The fuel tank is made of plastic, therefore do not clean it using trichloroethylene-based solvents. The use of trichloroethylene reduces the resistance of the tank. 145 WARNING
