accumulated, causing potential explosion or fire hazard.
• Do not attempt to set temperature limit above the preset limit.
• Never touch hot burner surfaces and stay clear of burner exhaust.
All are extremely hot and will burn you.
• Do not inhale burner exhaust. It contains dangerous carbon
monoxide that can kill you.
The burner will fire when the trigger is squeezed – follow instructions for
spraying.
Note:
If burner exhaust is white, adjust burner for peak performance. See the "Oil
Burner Adjustment Instructions" step in the "Burner Adjustment" section of
this manual.
When the trigger is released, a flow switch automatically turns the burner off.
Also, when the temperature setting is reached, the thermostat automatically turns
the burner off.
WARNING:
It is important that the burner stops firing when the trigger is
released. If the burner remains firing, discontinue use until the
pressure washer is serviced. Extremely high temperatures can result
in serious injury and equipment damage.
High Pressure Spray Procedure
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.
-
Always keep good footing and balance. 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
