Clean Parts or the Machine
Never clean the machine with caustic chemicals or steam cleaners. Instead, use mild soaps and a pressure washer to
clean the machine. Always protect electrical parts when cleaning the machine. Never flood or pressure wash the
inside of the operator’s cab. Use only nonflammable cleaning solvents. Never use flammable liquids to clean parts
or systems.
Covers and Locks
When servicing the machine with the doors open, be sure they are properly supported in place. Also be sure the
doors close tightly and latch securely in place. If a lock is present, be sure the lock is properly latched for security.
Inspection and Maintenance in Adverse Environments
If the machine will be operating under adverse conditions:
•
Check and clean any electrical components to avoid any accumulated corrosion.
•
Check and clean any areas where extreme heat is present, such as the exhaust system, manifold and
turbocharger.
For heavy load operation and deep excavation, add grease to the pins of the work equipment prior to each
operation. Cycle the operation of the boom, arm and bucket several times before refilling with additional grease.
Mud, Rain or Snow Conditions
After operating the machine, clean the machine, inspect for missing or loose bolts and nuts. Add oil and lubricating
grease as needed.
Near Ocean (Salt Air) Environments
Before operating the machine, inspect the machine for signs of corrosion. Apply grease where rust is found.
After operating the machine, thoroughly wash away the salt residue, apply grease where rust is found, and perform
maintenance carefully on the electric components to prevent corrosion.
NOTICE!
Failure to protect the electrical system when cleaning the machine may damage the machine
or cause it to operate improperly.
