Operating the machine in hot or cold weather
In cold weather
• Make sure to use fluids and lubricants which have specifications suitable for operation at low ambient temperatures.
• Check the batteries for full charge state.
• Fill up the fuel tank after completing the work, and then drain water before starting work on the next day in order to
prevent dew condensation and invasion of water to the fuel system.
• Use fuel which is rated to the outside air temperature, or proper anti-freeze in order to prevent crystal generation at
-2 °C (28 °F).
NOTICE: Before transporting the machine to a cold region, fill the tank with fuel that has a low freezing temperature.
In hot weather
• Make sure to use fluids and lubricants which have specifications suitable for operation at high ambient tempera-
tures.
• Keep the coolant at the correct level in the coolant reservoir and in the radiator.
• Use the correct solution of ethylene glycol and water in the cooling system.
• Test the radiator cap before hot weather starts. Replace the cap as required.
• Clean all dirt and debris from the radiator, cooler and engine area.
• Check the condition of the fan drive belt.
Operation under dusty and sandy conditions
• Frequently inspect the element of the air cleaner and clean or replace the element and the dust cup regardless of
service due.
• Tightly close the breather cap of the hydraulic tank to prevent invasion of sand and dust to the hydraulic circuits.
• Make sure to thoroughly clean the grease fittings before greasing any lubrication point of each pin and bush.
• Make sure to clean the radiator fin and oil cooler fin and the radiator grid.
Operation on seashore
• Inspect tightness of the plugs/cocks/bolts in each point in order to prevent salt corrosion.
• Thoroughly wash the machine after the work, especially take good care of the electrical equipment and hydraulic
cylinder to prevent corrosion.
Operation on highly humid land or soft land
• Keep the machine as dry as possible during operation and make sure to carry out regular lubrication. Moisture and
mud water cause deterioration and corrosion of paints/wirings/metal components.
