Clean Parts of the Machine
Never clean the machine with caustic chemicals or steam cleaners. Only use mild soaps and a pressure washer.
Always protect electrical parts when cleaning the machine. Never flood or pressure-wash the inside of the cab. Use
only nonflammable cleaning solvents. Never use flammable liquids to clean parts or any machine components.
Securing Access Covers and Compartment Doors
When servicing the machine with any access cover or compartment door open, use the lock bar to secure the cover
or door in the open position. Covers and doors that are not locked open can close unexpectedly and cause injury.
Installation of Hydraulic Hoses
When disassembling parts sealed by O-rings or gaskets, clean the surfaces before installing the new parts. Always
install new O-rings and gaskets.
Never kink or twist a hydraulic hose during removal or installation. Hydraulic hoses that have been kinked or
twisted can be damaged internally, which can considerably shorten the service life of the hose.
Inspection and Maintenance in Adverse Environments
If the machine will be operating under adverse conditions:
• Check and clean all electrical components and connections. Clean electrical components and connections
that show corrosion.
• Check and clean areas that are exposed to high levels of heat, such as the exhaust manifold and
turbocharger, and keep them clear of combustible materials.
For heavy-load operation, add grease to the pins of the work equipment prior to each operation. Cycle the operation
of all working parts several times before filling with additional grease.
Mud, Rain, or Snow Conditions
After operating the machine, clean the machine and inspect for missing or loose hardware. Add oil and lubricating
grease as needed.
Near Ocean (Salt Air) Environments
Before operating the machine, inspect for any signs of corrosion. Apply grease where corrosion is found.
After operating the machine, thoroughly wash away any salt residue, apply grease where corrosion is found, and
perform maintenance carefully on the electrical 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.
