DO NOT disconnect or remove any hydraulic system line or fitting unless hydraulic system pressure
has been relieved. Tighten all connections before applying pressure. Escaping hydraulic fluid under
pressure can penetrate the skin, causing serious injury.
Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids. If an acci-
dent occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed
within a few hours or gangrene may result.
At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before draining reservoir.
Failure to so do could result in injury.
Hydraulic fluid is very slippery. Immediately wipe up any spills. Failure to follow this warning may
result in injury to personnel.
Wipe drain plug and filters and surrounding areas clean prior to removal. After draining, immediately rein-
stall drain plug and cover openings into reservoir with a clean rag. Contaminated hydraulic system could
cause equipment failure.
