Storing and Handling Parts
• Store new parts (valves, pumps, motors, hoses, tubes)
in a clean, dry, indoor location.
• Do not unpack parts or remove port plugs until parts are
needed.
• Once unpacked, carefully inspect each part for damage
that may have occurred during shipping. Remove all
shipping material from ports of parts before installing
them.
• Fittings, hoses, and tubes that are not equipped with
shipping caps or plugs must be carefully cleaned before
they are used. Flush fittings, hoses, and tubes with clean
hydraulic oil. Then seal all openings until use at
assembly.
• Do not use rags to plug openings. Use clean plastic
shipping plugs and caps.
Inspecting System
The damaging effects of dirt, heat, air, and water in the
hydraulic system can only be prevented by regular, thorough
inspection of the system. The frequency of inspection
depends on operating conditions and experience with the
system; however, the more often the system is inspected
and deficiencies corrected, the less likely it is the system will
malfunction.
A good inspection program includes the following checks:
1. Keep accurate records so future maintenance needs
can be projected.
2. Check hydraulic oil level daily when oil is cold by looking
at hydraulic tank display on information screen in cab.
FULL COLD LEVEL
(approximately 60°F (16°C)
Screen should read 90 to 94%.
FULL HOT LEVEL
(approximately 180°F (82°C)
Screen should read 100%.
Do not fill tank to 100%. Oil will flow out of breather.
3. If oil level drops to 60%, fault alarm will come on and
fault Hydraulic Fluid Low icon will appear on fault screen
(Figure 2-2
). Fill tank immediately.
