During The Period Of Inactivity; After The Period Of Inactivity - Komatsu PC27R-8 Operation & Maintenance Manual

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

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 - Release the exhaust pipe and the fuel tank from the seals.
2 - Check all the levels (engine oil, coolant, fuel, hydraulic circuit 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 about 20 minutes.
8 - While the engine is warming up, remove the protection grease from the hydraulic cylinder rods.
9 - Before moving the machine, make sure that the instruments, warning lights and working lights operate cor-
rectly.
10 - Warm the hydraulic cylinders as soon as possible, by slowly moving all the equipment.
