mechanical properties and long term exposure to these cold
temperatures will negatively impact service life. It is
recommended for these hoses to be inspected to step 1
above as service life may be more than 8,000 hours.
HYDRAULIC SYSTEM – MAINTENANCE
Safety
• Lower or securely block hydraulically operated
attachments and loads before servicing. Do not rely on
controls to support attachments or loads.
• Stop engine and relieve hydraulic pressure to zero
before servicing or disconnecting any part of hydraulic
system. After stopping engine, operate controls in both
directions to relieve pressure.
• Before servicing hydraulic system, attach warning sign
to engine start controls to warn other personnel not to
start engine.
• Do not perform hydraulic system maintenance,
adjustment or repair procedures unless authorized to do
so. If authorized, make sure all applicable instructions
have been read and are thoroughly understood.
• Do not alter specified pressure settings. Higher than
specified pressures can cause structural or hydraulic
failure. Lower than specified pressures can cause loss
of control.
• Never check for hydraulic leaks with hands. Oil under
pressure can penetrate skin, causing serious injury. Oil
escaping from a small hole can be nearly invisible;
check for leaks with a piece of cardboard or wood.
Storing And Handling Oil
• Store oil drums in clean, cool, dry location. Avoid
outdoor storage.
• Store oil drums on their side and cover them to prevent
water and dirt from collecting on them.
• When handling drums and transfer containers, use care
to avoid damage which can cause leaks and entry of dirt
or water into oil.
• Before opening a drum, carefully clean top of it. Also
clean faucet or pump to remove oil from drum.
• Only use clean transfer containers.
• Do not take oil from storage until oil is needed. If oil
cannot be used immediately, keep transfer container
tightly covered.
Storing And Handling Parts
• Store new parts (valves, pumps, motors, hoses, tubes)
in 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.
• Fittings, hoses, and tubes that are not equipped with
shipping caps or plugs must be cleaned before being
used. Flush fittings, hoses, and tubes with clean
hydraulic oil. Seal all openings until use at assembly.
• Do not use rags to plug openings. Use clean plastic
shipping plugs and caps.
