WARNING: High pressure spraying safety

Keep spray away from people. Never direct discharge stream at or near any
person. Do not allow any part of the body to come in contact with the fluid
stream. High-pressure spray can cause serious skin, eye, or falling injuries,
and hot water can burn. Injection injury will occur if high-pressure spray
pierces the skin, injecting liquid under the skin. Injection injury can result in
blood poisoning and/or severe tissue damage leading to infection, gangrene
and possibly amputation. Seek medical attention.

Do not secure trigger open. To reduce risk of injury, do not attempt to
secure the spray gun open by blocking or tying the spray gun in the open
position.

Prevent slips / loss of balance. High-pressure spray could cause you to lose
balance from kickback forces, and wet surfaces can be slippery.
- Keep good footing and balance at all times. Do not overreach.
- Do not stand on unstable support when spraying.
- If spraying from an elevated surface, use fall protection because
spray gun kickback can propel you off the elevated surface. When
spraying from a ladder or scaffolding, ensure it is firmly anchored
from sway or tip-over.
- Be aware of puddles and slippery surfaces. Ensure there is adequate
drainage to prevent pooling of water.

Prevent surface damage & flying debris – Surfaces being sprayed must be
strong enough to withstand high-pressure spray or damage may result. In
addition, high-pressure spray will dislodge unsecured objects as well as
surface chips and debris, resulting in hazardous flying objects that can cause
personal injury or property damage. Do not spray brittle surfaces or
breakable, fragile, or unsecured objects such as:
o stucco or laminar flagstone
o some painted surfaces
o windows or glass doors (because they may break)
o light fixtures, flowerbeds, mailboxes
o unsecured, lightweight objects
Procedure:
1. Put on one of the high-pressure spray nozzles (always relieve system
