When working around moving components, use caution as these devices could be activated without warning.
Always lock out energy sources. Do not re-start the machinery until the entire system has been checked,
all guards are in place, all gates closed and locked, and all personnel are informed of start-up!
Maintenance Personnel should be familiar with equipment safety features prior to any maintenance action.
Ensure that all power is removed and locked out prior to any maintenance action.
Before performing maintenance procedures, follow posted Lockout Procedures.
If any safety device tests fail, stop the system immediately, lockout the disconnect switch, and notify
your supervisor to have the problem corrected.
Before attempting any troubleshooting procedures, ensure machine is taken out of automatic mode at the
HMI.
Equipment left in automatic mode is dangerous, especially if the system stopped during an automatic sequence.
When the equipment shuts down because of a fault, do not perform any maintenance until the equipment is
first properly locked out.
Some general maintenance safety precautions are outlined below. The tables are intended
as a guideline and should not replace maintenance safety standards derived in the plant.
Mechanical maintenance, adjustments, and repairs should be performed only by qualified
technicians familiar with the system.
If mechanical service does not require the station to be powered up, disconnect and dissipate
all energy sources and perform the appropriate lockout / tagout procedures.
Maintenance work will not be performed until all hazardous energy sources to which employees
may be exposed is controlled. Before proceeding with any equipment maintenance or repairs,
verify that power is removed. Refer to the Verification Procedures outlined on the
ECPL
placard to ensure energy source is controlled and start up of the energy source is not possible.
Vertical or inclined sliding members should be properly blocked. Use of safety pins (where provided)
to mechanically disable machine motions is highly required.
All moving machinery components, as well as their surrounding areas should be kept free of tools, rags,
dirt, and excessive oil.
When guards are removed for repair work, they should be properly re-installed as soon as the
work is completed. Prior to operating any machinery all protective guards and covers must be in position.
For troubleshooting, it may be necessary to leave the power &quout;ON". Always be aware of
hazardous energy sources.
Keep all moving parts of machinery and surrounding areas free of tools, rags, dirt, and oil. Clean
up oil spills immediately.
Before operating any moving machinery after maintenance is performed, all protective guards must be
in place, all panel doors are closed and secured, and all safety gates are closed and secured.
Electrical system maintenance should be performed only by qualified electrical technicians
familiar with the system using the latest up-to-date electrical controls drawings.
A qualified electrician should be present when the electrical control panels are opened to
perform checks and required repairs.
Before performing maintenance or service on any part of the electrical system, perform
all applicable lockout / tagout procedures. Before proceeding, verify that power is
removed from all circuits.
Maintenance work will not be performed until the hazardous energy to which employees
may be exposed is controlled. This prevents the system from being powered on or re-started unexpectedly.
A preliminary test should be conducted to confirm that no voltage is present before working on any circuit.
Use only specified regulation fuses and never improvises for the replacement of fuses. Use approved
fuse pullers when replacing the fuses.
For troubleshooting, it may be necessary to leave the power “ON”. Always be aware of hazardous energy sources.
Keep all moving parts of machinery and surrounding areas free of tools, rags, dirt, and oil. Clean up
any spills immediately to prevent slip hazards.
Before operating any moving machinery after maintenance is performed, all protective guards must be in
place, all panel doors are closed and secured, and all safety gates are closed and secured.
Pneumatic system maintenance should be performed only by qualified technicians familiar
with the system using the latest up-to-date pneumatic schematics drawings.
Before performing maintenance or service on any parts of the Pneumatic System, shut off the air supply
at the main shutoff valve and bleed air from pneumatic lines. Perform all applicable lockout
/ tagout procedures.
While moving a pneumatic lockout valve to the off position, beware that high pressure and
contaminates in the circuit will expel from the valve into a silencer/muffler to
relieve pressure in that circuit.
Trapped air may exists in air circuits between a 3-position control valves (with all ports
blocked in the center position) and the air cylinder Trapped air may also exists in air
circuits between a check valve and the air cylinder. Check the pneumatic drawings provided
for any trapped air circuits. Relieve pressure in any trapped air circuits prior
to working on the pneumatic equipment.
Use extreme caution around automation (such as clamps, dumps, slides or lifts) that may
move when air is relieved from the station. Before relieving air from lines, secure all
such automation. Use safety pins where provided.
If the operating pressure is set too low, insufficient force may be developed at
the pneumatic actuator. Low pressure may be caused by dirty filter system.
Check filters for contamination.
Operating pressures that are set too high will cause excessive force at the actuator and may
damage the machinery or pneumatic components.
For troubleshooting, it may be necessary to leave the power "ON". Always
be aware of hazardous energy sources.
Keep all moving parts of machinery and surrounding areas free of tools, rags, dirt, and oil.
Clean up any spills immediately to prevent slip hazards.
Water system maintenance should be performed only by qualified technicians familiar with
the system using the latest up-to-date pneumatic schematics drawings.
Be sure to shut off the main water supply, relieve any system pressure, and lockout prior to
performing any working on the water system.
Prior to loosening of water connections or other actions, the main electrical disconnect switch
must be open (off) and locked out and main water supply at the distribution stand or individual
water circuits as required.
Operating pressures that are set too high may cause damage to the machine fluids lines and
possibly result in injury to personnel.
Keep all moving parts of machinery and surrounding areas free of tools, rags, dirt, and
oil. Clean up any spills immediately to prevent slip hazards.
Before operating any moving machinery and after maintenance is performed, all protective
guards must be in place, all panel doors are closed and secured, and all safety gates are
closed and secured.
