OPERATOR SAFETY INSTRUCTIONS
DANGER MEANS: If you do not follow the instructions in a DANGER, severe bodily injury or death can occur to you
and/or other personnel.
WARNING MEANS: If you do not follow the instructions in a WARNING, injury can occur to you or to other personnel.
CAUTION MEANS: If you do not follow the instructions in a CAUTION, damage can occur to the machine or to other
property.
WARNING: Do not use gasoline, crankcase drainings, or oil containing gasoline or solvents.
WARNING: This machine is not to be connected to a type B gas vent.
WARNING: Risk of injection or severe injury. Keep clear of nozzle. Do not direct discharge stream at persons. This
equipment is to be used only by trained persons.
WARNING: If you smell gas, shut off the gas supply to the appliance, extinguish any open flame, and test all joints with a
soap solution. If the odor persists, call your gas supplier immediately.
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 pressure 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.
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 kero-
sene, 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 your local authorized Delco distributor.
DANGER: Operating a pressure 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, discon-
tinue use immediately and contact your local authorized Delco distributor 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.
DANGER: Operating a machine with a ground fault circuit interrupter (GFIC) that has been tampered with, or one that
repeatedly trips, could result in an electrocution. Do not remove, disable, or tamper with the GFCI. If the ground
fault circuit interrupter repeatedly trips, discontinue use of the machine. Contact your local authorized Delco
distributor for assistance with the GFCI.
DANGER: Electrocution could occur if the machine is used on a power circuit that repeatedly trips or is undersized. Have a
licensed electrician check the fuse, circuit breaker or power supply, and/or contact your local authorized Delco
distributor for assistance.
DANGER: Electrocution could occur if maintenance and repairs are performed on a unit that is not properly disconnected
from the power source. Disconnect the power supply before attempting any maintenance or service.
DANGER: Use of this machine with a damaged power cord could result in an electrical shock. Do not use the machine if
the power cord is damaged. Do not use the electrical cord to move the machine.
WARNING: Water under high pressure can cause severe injury. Keep all persons away from the machine and the spray
area. Always point the wand toward the object being cleaned.
