OPERATING INSTRUCTIONS
PROLONGED MACHINE INACTIVITY
DANGER Do not run the engine in confined spaces without proper ventilation and/or a suitable system capable of removing.
WARNING Explosive gas is produced while batteries are being charged. Keep naked lights and/or sparks away from the battery charging area. Remove cell plugs during recharging. Take care to make correct connections. Never connect a positive terminal (+) to a negative terminal (-).
• Paint parts needing it to prevent rust formation. • Store the machine in a dry protected place. If the machine is parked outside, cover it with a tarpaulin arranged to allow ventilation. If not, humidity harmful to the machine may result. • If the machine is to be stored for a prolonged period of time, operate travel, swing and digging hydraulic systems at least once per month to guarantee proper lubrication. • Before operating the machine, check coolant level (or refill the system if drained) and lubrication conditions. • Check battery charge each month and recharge, if necessary.
• Inspect the machine. Repair damaged or worn parts. Install new parts, if necessary. • Clean the air filter. • Fully retract all cylinders, if possible. If not, coat the exposed cylinder rods with grease. • Lubricate all grease points. • Park the wheels on long stable blocks. • Wash the machine. • Remove the batteries and store in a dry protected place after charging fully. If not removed, disconnect battery negative cable from the terminal (-). • Drain coolant. If the system is filled with antifreeze mixture, draining is not necessary.

• Release alternator and fan belts. • Remove the injectors and inject a small amount of engine oil into the cylinders through the injector holes. This operation should be carried out using a syringe after bringing each piston to the bottom dead centre. After injecting, crank the engine several turns (using the starter motor) to spread a protective coat of oil over cylinder walls. Reinstall the injectors.
