Safety

WARNING: Protect machine from

freezing.

16. To keep machine in best 

operating conditions, it is 
important you protect machine 
from freezing. Failure to protect 
machine from freezing could 
cause malfunction of the 
machine and result in death, 

serious bodily injury, and/or property damage. 
Follow storage instructions specified in this 
manual.

17. Inlet water must be clean fresh water and no hotter 

then 90°F.

DANGER: Risk of asphyxiation. 
Use this product only in a well 
ventilated area. 

18. Running this product indoors 

can result in death due to carbon 
monoxide, a poison gas you 
cannot see or smell. Never 
operate indoors, even if windows 
and doors are open. Only use 
outdoors and far away from 

windows, doors and openings or vents.

19. Manufacturer will not be liable for any changes 

made to our standard machines or any compo-
nents not purchased from us.

20. The best insurance against an accident is precau-

tion and knowledge of the machine.

WARNING: Be extremely careful 
when using a ladder, scaffolding 
or any other relatively unstable 
location. The cleaning area 
should have adequate slopes and 
drainage to reduce the possibility 
of a fall due to slippery surfaces.

21. Do not allow acids, caustic or abrasive fluids to 

pass through the pump.

22. Never run pump dry or leave spray gun closed 

longer than 1-2 minutes.

23. Machines with shut-off spray gun should not be 

operated with the spray gun in the off position for 
extensive periods of time as this may cause 
damage to the pump.

24. Protect discharge hose from vehicle traffic and 

sharp objects. Inspect condition of high pressure 
hose before using or bodily injury may result.

25. Before disconnecting discharge hose from water 

outlet, turn burner off and open spray gun to allow 
water to cool below 100° before stopping the 
machine. Then open the spray gun to relieve 
pressure. Failure to properly cool down or maintain 
the heating coil may result in a steam explosion.

26. Do not overreach or stand on unstable support. 

Keep good footing and balance at all times.

27. Do not operate this machine when fatigued or 

under the influence of alcohol, prescription medica-
tions, or drugs.

Laws Pertaining to Spark Arrestors

Notice:

 State Health Safety Codes and Public 

Resources Codes specify that in certain locations spark 
arrestors be used on internal combustion engines that 
use hydrocarbon fuels. A spark arrestor is a device 
designed to prevent accidental discharge of sparks or 
flames from the engine exhaust.

For users on U.S. Forest Land and in the states of 
California Maine, Oregon and Washington:

 All U.S. 

Forest Land and the state of California (Public 
Resources Codes 4442 and 4443), Oregon and Wash-
ington require, by law, that certain internal combustion 
engines operated on forest brush and/or grass-covered 
areas be equipped with a spark arrestor, maintained in 
effective working order or that the engine be 
constructed, equipped and maintained for the preven-
tion of fire. Check with your state or local authorities for 
regulations pertaining to these requirements. Failure to 
follow these requirements could subject you to liability 
or a fine. 

This unit is factory designed to be equipped 

with a spark arrestor.

 If you require a spark arrestor, ask 

your LOCAL SERVICE DEALER to install:

Accessory Part # 8.919-989.0 Spark Arrestor Kit.

California Proposition 65 Warning:

Engine exhaust, some of its constituents and certain 
engine components, contain or emit chemicals known 
to the State of California to cause cancer and birth 
defects or other reproductive harm.

Follow the maintenance instructions 
specified in the manual.
