IMPORTANT INFORMATION
GENERAL SAFETY GUIDELINES
WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS. Failure to follow
instructions and warnings could lead to serious injury, electric shock, or fire. Save ALL warnings
and instructions for future reference.
WORK AREA SAFETY
-Ensure that your work area is kept well-lit and clean. Lack of visibility and clutter greatly
increase the risk of accident.
-Keep bystanders and children clear when operating a power tool or machine. They can
cause distraction or risk injury themselves.
-Ensure you are not operating the power tool or machinery in the presence of flammable
gases, dust, liquids, or anything that creates an explosive atmosphere. Power tools and

FUEL & ENGINE SAFETY
Petrol engine exhaust contains carbon monoxide, a colorless, odorless, poison gas. Breathing carbon
monoxide will cause nausea, dizziness, fainting or death. If you start to feel dizzy or weak, get fresh
air immediately.
OPERATE THE WATER BLASTER OUTDOORS ONLY IN A WELL-VENTILATED AREA AND POINT
EXHAUST AWAY.
-DO NOT operate the water blaster inside any building, including garages, basements,
crawlspaces and sheds, enclosure, or compartment, including the storage compartment of a
recreational vehicle.
-DO NOT allow exhaust fumes to enter a confined area through windows, doors, vents, or
other openings.
Using an engine indoors CAN KILL YOU IN MINUTES. Engine exhaust contains carbon monoxide.
This is a poison you cannot see or smell.
NEVER use inside a home or garage, EVEN IF doors and windows are open. ONLY use OUTSIDE and
far away from windows, doors, and vents.
Spark from removed spark plug wire can result in fire or electrical shock. When servicing the water
blaster:
-Disconnect the spark plug wire and place it where it cannot contact the plug or any other
metal object.
-DO NOT check for spark with the plug removed.
-Use only approved spark plug testers.
DANGER: GASOLINE AND GASOLINE VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE. Fire or
explosion can cause severe burns or death.
Gasoline and Gasoline Vapors
-Gasoline is highly flammable and explosive.
-Gasoline can cause a fire or explosion if ignited.
-Gasoline is a liquid fuel, but its vapors can ignite.
-Gasoline is a skin irritant and needs to be cleaned up immediately if spilled on skin or
clothes.
-Gasoline has a distinctive odor; this will help detect potential leaks quickly.
-In any petroleum gas fire, flames should not be extinguished unless by doing so the fuel
supply valve can be turned OFF. This is because if a fire is extinguished and a supply of fuel is
not turned OFF, then an explosion hazard could be created.
-Never fill gas tank to capacity as gasoline needs room to expand if temperature rises.
