which can become widespread during fueling. A flash fire and/or explosion could result and
cause serious injury or death. Always use extreme care when handling fuels. Carefully follow
all instructions to avoid the following conditions which could result in fuel ignition:
gas vapor collection inside enclosures
static electric sparks
sparks from electric wiring, batteries, or running engines
sources of heat (such as a hot engine exhaust)
open flames, including pilot lights

Before Each Use
18
Always follow these general safety rules when fueling:
1) Turn pressure washer off and allow to cool for at least two minutes before removing any fuel cap.
Note: A running or still-hot engine is hot enough to ignite fuel.
2) Fill fuel tank OUTDOORS –never indoors. Fuel vapors can ignite if they collect inside and
enclosure and explosion can result.
3) Stay away from all sources of heat, sparks, and flames. Do not smoke.
4) Never pump fuel directly into the gas tank at a gas station –it could cause a static electric spark.
Follow these steps to avoid static electric sparking during fueling:
Use an approved portable container to transfer fuel to the pressure washer's
tank. (A portable container made of metal or conductive plastic is preferred
because it dissipates charge to ground more readily.)
Always place container on the ground to be filled. Never fill the portable gas
container while it is sitting inside a vehicle, trailer, trunk, or pick-up truck
bed.
Dissipate static charge from your body before beginning the fueling process
by touching a grounded metal object at a safe distance from fuel sources.
Keep nozzle in contact with container while filling. Do not use a nozzle lock-
open device.
5) Clean up fuel spills/splashes immediately.
If possible, move the pressure washer away from spilled fuel on the ground.
Wipe up spilled fuel and wait 5 minutes for excess fuel to evaporate before starting
engine.
Fuel soaked rags are flammable and should be disposed of properly.
If fuel is spilled on your skin or clothes, change clothes and wash skin immediately.
Fill engine fuel
tank
Check the gasoline tank level. If needed, fill tank with fresh unleaded
gasoline from a portable container:
1) Remove engine gas cap.
2) Add gasoline through the fill opening:
- Use only a UL-approved portable gasoline container to transfer the gasoline
to engine's tank.
- Do NOT overfill the gasoline tank. Allow at least 1/2" of empty space
below the fill neck to allow for fuel expansion.
3) Replace gas cap securely before starting engine.
4) Store extra gasoline in a cool, dry place in an UL-approved, tightly sealed
container.

Before Each Use

Step 3. Select Suitable Outdoor Worksite
Before using the pressure washer, you must understand the criteria for selecting a suitable location
for operation. Note that this pressure washer is for OUTDOOR USE only.
WARNING:
You must choose a suitable site for operating your pressure washer to avoid equipment
damage and/or injury and possible death from carbon monoxide poisoning, fire/explosion,
uncontrolled equipment movement/tip over, or slips and falls. Choose a site that meets all
of the following five criteria:
1. OUTDOORS only, and away from all building windows and air intakes.
2. Where no flammable vapors, dusts, and gases are present.
3. Where there is adequate, unobstructed ventilation airflow.
4. With adequate clearance from combustible materials.
5. On a firm, level, heat-resistant surface with good drainage.
Detail regarding each of these criteria are provided below.
1. Outdoors
ONLY
DANGER: Carbon monoxide poisoning hazard
Exhaust fumes from the engine contain carbon monoxide (CO), a
poisonous gas you cannot see, smell, or taste. The CO generated by the
pressure washer can rapidly accumulate, even in areas that appear to be
well ventilated, resulting in dangerous and fatal concentrations within
minutes. Follow the directions below for choosing a location to operate
your pressure washer in order to avoid carbon monoxide poisoning.
The location you choose to operate the pressure washer must be
OUTDOORS and away from all building air intakes.
Never run the pressure washer in an enclosed or partially enclosed location
such as a building, garage, barn, shed, or house. These spaces can trap
poisonous gases. Running a fan or opening windows will not provide
adequate ventilation to prevent dangerous CO build-up.
Only use the pressure washer outdoors and far away from open windows,
doors, and building or vehicle vents.
Place the pressure washer so that the exhaust fumes will not be directed
towards people or building air intakes.
Ensure that working, battery-operated or battery back-up carbon monoxide
alarms are used in any dwelling/structure that is in close proximity to the
running pressure washer.
Note that this pressure washer is NOT designed or approved for use in
vehicles or marine applications. Never run the pressure washer inside RVs
or other vehicles, on boats, or on pick-up truck beds.
WARNING:
Never attempt to attach ductwork to the engine muffler exhaust to allow
for installation inside an enclosure. This could cause hot air deflection,
heat build-up, and increased exhaust back-pressure, resulting in possible
exhaust leakage or overheating and damage to the pressure washer.

Before Each Use
20
2. Away from
combustible
dust, liquids,
or vapors
Do not locate and use the pressure washer in the presence of flammable
vapors, dust, gases, or other potentially combustible materials.
3. Adequate
ventilation
airflow
The pressure washer needs adequate, unobstructed flow of air to allow for
proper combustion and adequate cooling. Proper combustion can only be
obtained when there is a sufficient supply of oxygen available for the amount of
fuel being burned. Cooling ventilation is required to prevent overheating of the
pressure washer and possible fire.
Situate so there is adequate clearance around pressure washer to allow for
airflow –at least 7 feet from any non-combustible wall or obstruction.
Never place any objects against or on top of the pressure washer.
Do not operate with a tarp, blanket, or cover surrounding the pressure
washer.
4. Hot exhaust
clearance
The exhaust gas from your pressure washer is extremely hot and can cause
combustible materials to catch on fire.
Make sure the engine is at least 7 feet from all combustible materials and
buildings/structures during operation.
Equip the engine with a spark arrestor if the pressure washer will be used
near any ignitable forest, brush, or grassy land. (See the engine manual
provided with this equipment to determine if the engine is already
equipped.) Make sure you comply with applicable local, state, and federal
codes.
Keep a fire extinguisher rated "ABC" nearby. Keep it properly charged and
be familiar with its use.
5. Firm, level,
heat-resistant
surface with
nearby water
supply
The pressure washer should be positioned on a firm, level (less that 3 degree
slope), heat-resistant surface with good drainage and a nearby water supply.
The pressure washer should be placed within garden hose distance of a
continuous water supply. Ensure that the pressure washer sits level and will not
slide or shift during operation. If applicable, block the pressure washer's wheels
to prevent movement.
