Check Hydraulic Lines and Hoses
IMPORTANT: Checkhydraulic linesandhosesdaily
for leaks, kinked lines, loose mounting supports,
wear, loose fittings, weather deterioration and
chemical deterioration. Make all necessary repairs
before operating.
WARNING
Keep body and hands away from pin hole leaks
or nozzles that eject hydraulic fluid under high
pressure. Use paper or cardboard, not hands, to
search for leaks. Hydraulic fluid escaping under
pressure can have sufficient force to penetrate
the skin and cause serious injury. If fluid is in-
jected into the skin, it must be surgically re-
moved within a few hours by a doctor familiar
withthistypeofinjury.Gangrenemayresultfrom
such an injury.
Flush Hydraulic System
IMPORTANT: Flush the hydraulic system any time
there is a severe component failure or the system is
contaminated (oil appears milky, black, or contains
metal particles).
Note:
Useonlyhydraulic fluidsspecifiedinOperator’s
Manual. If changing to to biodegradable fluid, use Mobil
EAU 224H for this step. Other fluids may cause system
damage.
IMPORTANT: Flush hydraulic system when chang-
Ing from petroleum base hydraulic fluid to a biode-
gradable fluid such as Mobil EAU 224H. Operate
machine under normal operating conditions for at
least four (4) hours before draining.

Change Hydraulic Fluid).

IMPORTANT: Make sure to clean around hydraulic
connections that will be disconnected for draining.
13.Shut off engine and check for hydraulic oil leaks.
Check oil level in hydraulic reservoir and add correct
amount of oil if necessary.

3.
Drain hydraulic system. Drain all hoses, tubes, and
components while the system is warm.
15.Check condition of hydraulic oil. If the new fluid
shows any signs of contamination, repeat steps 1
through 15 again until oil is clean. If you are changing to
biodegradable fluid, repeat steps 1 through 15 again at
least once and until the oil is clean.
4.
Change and replace oil filter (see Change Hydraulic
Oil Filter).
5.
Inspect and clean hydraulic reservoir (see Hydraulic
Reservoir Inspection).

normal operation and follow recommended
maintenance intervals.
6.
Reconnect all hydraulic hoses, lines, and compo-
nents that were disconnected while draining system.
