DANGER
Dangerous voltage
To reduce the risk of serious injuries or death, wear approved protection and follow safety
recommendations when working with electricity.
WARNING
People who maintain and repair this equipment can be injured or killed if hazardous energy is not
properly controlled. Injuries can include burns, cuts, fractures, or electrocution.
Turn off electrical power and relieve all water and hydraulic pressure from the pump before starting
maintenance or repairs.
Disconnect and lock out or tag out the electrical main before opening the electrical enclosure or
doing maintenance or repair procedures. Refer to
page 97
for additional information.
WARNING
People who work on deenergized machinery can be seriously injured or killed if someone removes
lock-out or tag-out devices and reenergizes machinery without their knowledge. All workers must
respect lock-out and tag-out devices and that only the person(s) who applied these devices remove
them.
WARNING
A waterjet is a cutting tool. A high-pressure injection injury is a surgical emergency. Seek immediate
medical treatment for all high-pressure waterjet injuries. Delayed treatment can cause serious
injuries or death.
Keep skin away from high-pressure streams and leaks. Pressurized fluid can cause severe injuries.
Abrasive waterjets eject a mixture of water and abrasive materials that can be injected into body
tissues, leading to a serious infection. Get immediate surgical attention after contact with
high-pressure stream of fluid.
WARNING
Personal protective equipment is recommended. Failure to wear personal protective equipment can
cause injuries or death.
WARNING
Use a piece of cardboard or other solid material to find leaks when the pump is operating. Do not
use hands, cloth, paper, or towels.
WARNING
Do not repair a leak with high-pressure water in the system. Discharge all high-pressure water
before working on this equipment.
WARNING
Do not touch a hot surface.
Fittings can get hot, especially when they are not tightened properly.
CAUTION
Support all plumbing to prevent bending stress and fatigue from vibration. A disruption or crack in
plumbing can cause injuries to people or damage to equipment.
High-pressure water can cause eye injuries. Wear approved eye protection when operating or
working near this equipment.
This waterjet equipment might exceed national and local codes for permitted noise levels.
When this pump is running, the noise level is 75 dB(A) to 80 dB(A). Noise level is related to factors
such as water flow rate, pipe layout, and the acoustical characteristics of the building.
Prolonged exposure to noise can cause permanent hearing loss. Wear approved ear protection and
control exposure time when operating or working near this equipment.
Precision parts have sharp corners or edges. Wear protective gloves when handling parts.
