During The Period Of Inactivity; After The Period Of Inactivity - Komatsu SK818-5 Operation & Maintenance Manual

LONG PERIODS OF INACTIVITY

3.14.2 DURING THE PERIOD OF INACTIVITY

If it is necessary to carry out a rust-prevention treatment while the machine is kept indoors, open doors
q
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 mo-
ving parts and the surfaces of the components. Provide also for charging the battery.

3.14.3 AFTER THE PERIOD OF INACTIVITY

IMPORTANT
If the machine is stored without carrying out the monthly rust-prevention treatment, have maintenance
q
performed by your Komatsu Dealer.
When using the machine after a long period of inactivity, proceed as follows:
1 - Free the exhaust pipe from the sealing covers.
2 - Check all the fluid levels (engine oil, coolant, fuel, hydraulic circuit and transmission oil).
3 - Make sure that the battery is charged and install it on the machine.
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 restore the lubricating oil circulation and to carry out a first lubrication cycle.
6 - Reconnect the engine stop solenoid and start the engine.
7 - Start the engine and let it idle for approximately 20 minutes.
8 - While warming up the engine, remove the protection grease from the hydraulic cylinder rods.
9 - Before moving the machine, make sure that the instruments, the warning lights and the working lights operate
correctly.
10 - Warm up the hydraulic cylinders as soon as possible, by operating all the equipment slowly.
