Before Each Use

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.
Burner is an open flame,
which can ignite airborne dusts and flammable vapors. Operate only where open flame
or torch is permitted.
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 both the engine exhaust and burner exhaust are at least 7 feet from all
combustible materials and 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.
Surface should be heat resistant if you will be using the burner for heated spray.
