Safety
Read and understand all the safety guidelines in this manual.
Refer to Safety on page 19 before operating, doing maintenance on, repairing and
installing the pump.
DANGER
A waterjet is a cutting tool. Keep away from high-pressure streams and leaks.
Pressurized fluid can cause injuries.
A high-pressure injection injury is a surgical emergency. Get medical treatment
immediately for all high-pressure waterjet injuries.
Delayed treatment can cause injuries or death. Abrasive waterjets eject a mixture of
water and abrasive materials that can be injected into body tissues, leading to a
dangerous infection.
DANGER
Doing work on this equipment while it is energized is dangerous.
Personnel who maintain and repair this equipment can be injured or killed if dangerous
energy is not controlled. Injuries can include burns, cuts, fractures, or electrocution.
Before opening the electrical enclosure or doing maintenance or repairs on this
equipment, turn
OFF
the electrical power and release water pressure and hydraulic
pressure from the system.
Use standard lock out–tag out procedures. Isolate all sources of electrical, mechanical,
hydraulic, pneumatic, chemical, thermal, or other energy with a lockable
energy-isolating device that satisfies national and local requirements.
All work that requires opening the electrical enclosure or removing covers or panels
from this equipment must be done only by an approved technician.
DANGER
A person who works on deenergized machinery can be injured or killed if the machinery
is energized without permission.
All personnel in an area where energy-control procedures are used must receive
training for energy-control procedures.
DANGER
Do not stand in line with high-pressure fittings when operating this equipment. If a
high-pressure fitting fails, it can cause a stream of water or hydraulic fluid to eject from
the system with force.
WARNING
Personal protective equipment is recommended. If you do not use personal protective
equipment, there is a risk of injury or death.
WARNING
Permit only approved personnel to operate, maintain, and repair this machinery.
WARNING
Release all high-pressure water before doing work on this equipment.
