precautions should be included in the comprehensive safety
program for the particular machinery, equipment, plant or
process and overseen by personnel capable of analyzing any
hazards associated with operating and maintaining the
equipment.
WARNING
Many types of
machinery have
parts that may
start moving as soon as the
hydraulic circuit is filled and
pressurized. This could result
in injury to personnel or dam-
age to machinery.
1. Return all movable parts of the machinery being oper-
ated to their normal startup condition, if possible,
before starting unit.
2.
Be sure all personnel, product, etc. are clear of
machinery before starting hydraulic unit.
3. Check to make sure any hydraulic connections which
may have been removed, replaced or disconnected
during shut down have been reconnected securely
before starting hydraulic unit.
4.
Before starting the unit, perform all equipment checks
described at the beginning of the operating instruc-
tions.
5. If there are tools or machinery being operated by the
HPU that may move when hydraulic flow or pressure
are turned off or turned on, block or lock these parts in
position before shutting down the hydraulic unit.
WARNING
Make sure all per-
sonnel are clear
from the machin-
ery being operated before
shutting down the HPU.
6.
Shut down the hydraulic unit and relieve pressure
from all pressurized accumulators, actuators and lines
before removing, tearing down or performing mainte-
nance on any remotely-located actuators, hoses, fil-
ters, valves, piping, etc.
7. Any personnel observing or working on or adjacent to
hydraulically-powered equipment must never place
themselves in a location or position that could produce
an injury in the event of:
• a hydraulic line failure either with the unit running or
shut down;
• pump or motor failure or;
• pin-hole leaks in hoses or fittings;
• movement of machine components during normal oper-
ation or resulting from a component malfunction or fail-
ure.
