HYDRAULIC SYSTEM MAINTENANCE

WARNING
Hydraulic fluid may be absorbed through the skin. If hydraulic fluid gets on your skin, thoroughly wash it
off with soap and water as soon as possible.
Always wear safety glasses when working on the hydraulic system. If hydraulic fluid gets in your eyes,
you can be blinded.
Hot equipment can burn you. Wait until hydraulic tubes and hoses are cool enough to touch before you
start work.
Cleaning compound can cause skin rash and can give off harmful vapors. To avoid injury, use in a well-
ventilated area. Wash immediately with soap and water if compound gets on skin or clothing.
Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Use only with effective
chip guarding and personal protective equipment (goggles/shield, gloves, etc.).
1.
Before taking off any hydraulic hoses, tubes or electrical harnesses, tag them to show location. Tagging saves time and
avoids errors. Remove tags after parts are installed.
WARNING
Wipe up spilled fluids immediately with rags. Hydraulic fluid is slippery.
2.
Put a rag under all connections to catch spilled fluids before you disconnect them.
3.
Unscrew connections with two wrenches. Use one wrench to unscrew the connection and the other wrench to hold the
fitting or line to keep it from twisting. Make sure any old sealing compound or tape is removed.
4.
Cap or plug all open hydraulic tubes, lines or fittings when you disconnect them. This will keep dirt and dust out of the
hydraulic system and will also stop fluid from siphoning through hoses and tubes. Do not take off caps or plugs until you
are ready to connect the system.
5.
Cover large openings or ports with cardboard, sheets of plastic or masking tape.
