your machine or in your Owner's Manual are ignored or are not adhered to. Read and
Observe all WARNING statements found in your Owner's Manual and on your

CAUTION means: Damage can occur to the machine or to other property if the CAUTION statements

found on your machine or in your Owner's Manual are ignored or are not adhered to.
Read and observe all CAUTION statements found in

DANGER: Failure to read the Owner's Manual prior to using this machine could result in injury to you or to other

personnel; damage to the machine or to other property could occur as well. You must have training
in the operation of this machine before using it. If you or your operator(s) cannot read English, have
this manual explained fully before attempting to operate this power washer.

DANGER: Machines can cause an explosion when operated near flammable materials and vapors. Do not

use this machine with or near fuels, grain dust, solvents, thinners, or other flammable materials.

your Owner's Manual and on

DANGER: This machine emits carbon monoxide. Asphyxiation could occur if the unit is used in an area with

poor or inadequate ventilation. Operate unit in a well-ventilated area. Do not connect the exhaust
stack directly to a flue pipe. This may cause sooting of the combustion chamber. If you must vent
to the outside use a hood type vent or an exhaust fan. Install flue pipes in accordance with all local
codes.

DANGER: Operating a machine that is not completely or fully assembled could result in injury or property

damage. Do not operate this machine until it is completely assembled. Inspect hoses, fittings, and
heat exchanger for leaks or fatigue before each use.

DANGER: Filling a machine with fuel in an explosive or poorly-ventilated area can cause an explosion. Only

fill the fuel tank in an open area. Do not fill the tank near open flames or while the unit is running.
Do not smoke while filling the tank. Do not over-fill the tank. Wipe up any spills. Tighten the cap
on the tank when finished. Use kerosene, or #1 or #2 diesel as a fuel only. DO NOT USE K-1

KEROSENE.

DANGER: Tampering with the machine's factory preset unloader valve setting and/or the pressure relief valve

setting could result in a machine explosion. Do not attempt to change the settings. Discontinue
use if a malfunction occurs and contact Customer Service.

DANGER: Operating a power washer with a malfunctioning burner or burner controls could result in a

machine explosion. Inspect burner and burner control operation before each use. If you suspect a
problem with the burner, discontinue use immediately and contact Customer Service
for assistance.

DANGER: Failure to properly maintain the heat exchange coil can result in a steam explosion. Scale or lime

build-up will act as an insulation and decrease the efficiency of the heat exchanger coil and will also
cause hot spots. This can result in a weakening of the tubing which in turn may cause a rupture.
