Waterjet system
•
High-pressure water can remain in the system for an
extended time after shutting down the water source.
Always bleed down system pressure before servicing
any part of the system.
•
Do not touch weep holes with your bare hands or
try to stop water by plugging the holes.
•
Remember that the waterjet stream is a knife. Do
not introduce anything into its path that you do not
intend to cut.
•
Wear a face shield when required by the operating
instructions.
•
Do not remove protective shields from high-pressure
tubing. If shields are removed for servicing, they
must be replaced before starting the system.
•
Torque all fittings to the manufacturer’s torque
specifications.
•
Stepping or leaning on high-pressure tubing can
break connections, causing leakage.
•
Use only high-pressure fittings, valves, and tubing
certified for 87,000 psi (6000 bar) when making
alterations or additions to the high-pressure water
system.
•
Do not alter or eliminate stress relief tubing coils.
•
Follow the tubing manufacturer’s recommendations
for high-pressure tube bending radii.
•
Do not exceed specified operating pressures for
high-pressure water system components.
•
Do not over-torque fittings or bend swivels excessively.
•
Follow the manufacturer’s recommendations for
servicing the equipment, and use only original
manufacturer replacement parts.
•
Follow the manufacturer’s system startup procedure
to ensure safe operation.
•
Use care when lifting equipment covers during
operation.
