5. Hydraulic hose assemblies operating in Zone D and E
should expect a degrade of mechanical properties and
long term exposure to these cold temperatures will
negatively impact service life. It is recommended 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 the engine and relieve hydraulic pressure to zero
before servicing or disconnecting any part of hydraulic
system. After stopping the 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 the engine.
• Do not perform hydraulic system maintenance,
adjustment or repair procedures unless authorized to do
so. 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. 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.
