Conditions
Maintenance
Water or near the ocean
Before operating, check the tightness of plugs and all drain hoses and cocks.
After working, replenish the grease to the attachment pins or the areas affected by the
water.
When operating the machine, make sure to check and lubricate attachment points
affected by water regularly.
After working near the ocean, clean the machine thoroughly with fresh water and
service the electrical parts to prevent from corrosion. It is highly recommended to use
dielectric grease in all harness connecting points for better sealing and to prevent
corrosion.
Freezing weather
After working, fill up the fuel tank to prevent water from condensing in the tank.
Use the recommended lubricants.
Fully charge the batteries regularly, electrolyte may freeze. Ventilate well especially
when the batteries are charged in a confined space.
When storing machines in extremely cold temperature, remove batteries and parking
them at room temperature.
Before parking, remove the mud and the dirt from the tyres.
Demolition work
Use fall protection against falling objects.
Low fuel quality
Drain the sediments in fuel tank at shorter service intervals.
Change the engine oil and engine oil filter at shorter service intervals.
Dusty atmosphere
Check regularly that hose and pipe connections from the air cleaner to the engine
induction manifold do not leak.
Clean the air filter at shorter service intervals.
Clean the clogging net for radiator and oil cooler at shorter service intervals.
Clean the areas on the machine where dust, chips and similar may collect at shorter
service intervals in order to minimize the risk of fire.
Pay attention to and clean the engine compartment and surrounding areas regularly.
Rocky ground
Use suitable tyres for the ground conditions. If in doubt, contact an authorised dealer
for information.
Use a suitable attachment for the ground conditions such as a heavy duty bucket.
