Regularly check the condition of hoses, pipes,
valves and various connections. Replace them as
necessary.
Before starting any maintenance work, stop all
hydraulic pumps, lock out pump motors, and
depressurize the system, bringing all components to
a zero energy state. Remember to also depressurize
the accumulators through the bleed valve for each
accumulator. Do not disconnect any hoses until the
actuator has been brought to a zero energy state and
properly secured.
Bleed the hydraulic system regularly to remove
entrapped air that may interfere with normal
expected machine operation or cause a hazard
during maintenance.
Electrical Equipment
Be especially cautious when working with or near
electrical equipment. An electric shock can be fatal.
Crushing Plant electrical outlets must be grounded
and have ground fault interruption protection. Tools
plugged into the outlets must be double insulated.
Never expose electrical equipment to mechanical
damage or humidity. Protect all electrical
equipment from direct contact with water or high
humidity.
Protect electrical devices that move as part of the
machine from dirt and mechanical damage.
Regularly check the operability of these devices.
The lockout program, locks, tags and the
blocking/restraining devices provided are designed
for your protection. Your responsibility is to follow
the program and use the proper equipment.
Remember:
– Follow procedures.
– Stay alert.
– Do not take anything for granted.
– Verify lockout.
– Each person working on the unit must
have his own lock with only 1 key.
– Tag must identify the work being done and
the person(s) who locked and tagged the
control.
– Locks and tags are changed with each shift
that comes on.
Work to prevent injury or death. Follow proper
procedures at all times!
Maintenance, repair and installation of electrical
equipment must be performed only by qualified
personnel who are familiar with the machinery and
equipment in question.
WARNING
Poorly tightened or damaged hydraulic
components may create dangerous jets of
fluid. Before restarting the machine, be sure
that the hydraulic system is ready for
operation, and personnel are clear of
affected areas.
WARNING
Machine parts may move unintentionally
and cause a risk of injury. Before restarting
the machine, make sure that all personnel
are clear of affected areas where machine
movement may occur.
DANGER
There is a risk of an electric shock, if
sufficient precautions are not taken. An
electric shock can be fatal.
For maintenance work, disconnect all
devices from electric and hydraulic power
sources and follow Crushing Plant lockout
procedures.
