LONG PERIODS OF INACTIVITY 3.14.2 DURING THE PERIOD OF INACTIVITY DANGER If it is necessary to carry out a rust-prevention treatment while the machine is kept indoors, open doors and windows to increase ventilation and avoid poisoning by gas. Start the engine and move the machine for a short distance once a month, so that a new oil film covers all the moving parts and the surfaces of the components. Provide also for charging the battery. 3.14.3 AFTER THE PERIOD OF INACTIVITY 134 IMPORTANT • If the machine is stored without carrying out the monthly rust-prevention treatment, have maintenance performed by your Komatsu Utility Dealer.
When using the machine after a long period of inactivity, proceed as follows: 1- Remove the seals from the exhaust pipe and the fuel tank. 2- Check all the fluid levels (engine oil, coolant, fuel, hydraulic circuit oil). 3- Make sure that the battery charge is sufficient and install the battery. 4- Disconnect the engine stop solenoid. 5- Turn the ignition key directly to the start position and keep it there until the engine oil pressure warning light goes out. This operation serves to start the circulation of the lubricating oil and to carry out a first lubrication cycle. 6- Reconnect the stop solenoid valve and start the engine.
Let the engine run at accelerated speed (approxi- mately 1200 rpm) for about 15 minutes. 7- While the engine is warming up, check the tyre pressure and remove the protection grease from the hydrau- lic cylinder rods. 8- Before moving the machine, make sure that the instruments, lights, direction indicators and brake stoplight work properly. 9- Warm up the hydraulic cylinders, by slowly moving all the work equipment as soon as possible. 10- Move at low speed and brake a few times in order to fluidize the oil and allow the setting of the braking sur- faces.
