SAFETY INSTRUCTIONS

RISK OF EXPLOSION OR FIRE

What can happen:
• Spilled petrol and its vapours can become ignited from cigarettes, sparks, electrical
arcing, exhaust gases and hot engine components such as the muffler.
After 50 Hours After 100 Hours
• Heat will expand fuel in the tank which could result in a fire.
or 3 Months or Yearly
• Operating the tool in an explosive environment could result in a fire.
• Muffler exhaust heat can damage painted surfaces, melt any materials sensitive
to heat (such as siding plastic, rubber or vinyl) and damage live plants. Keep hot tool
away from other objects.
• Improperly stored fuel could lead to accidental ignition. Fuel improperly secured
could get into the hands of children or other unqualified persons.
How to prevent it:
• Shut off engine and allow it to cool before adding fuel to the tank.
• Use care when filling the tank to avoid spilling fuel. Move tool away from fuelling
area before starting engine.
• Keep maximum fuel level 20mm below top of tank to allow for expansion.
• Operate and refuel in well ventilated areas free from obstructions.
(change if neccesary)
• Store fuel in a approved container (AS/NZS 2906-1999) for petrol. Store in a secure
location away from the work area. Make sure the container is clearly marked "fuel".

RISK OF UNSAFE OPERATION
What can happen
• Unsafe operation of your water blaster could lead to serious injury or death to you or others.
• The spray gun/wand is a powerful cleaning tool that could look like a toy to a child.
• Reactive force of spray results in gun/lance movement, potentiolly causing the operator to slip, fall
or misdirect the spray. Improper control of gun/lance can result in injuries to self, others and property
damage.
How to prevent it
• Become familiar with the operation and controls of the pressure cleaner.
• Keep children away from the pressure cleaner at all times.
• Never modify or remove the safety features of this product.
• Do not operate the machine with missing, broken or unauthorized parts.
• Never leave wand unattended while unit is running.
• Keep work area free of obstacles.
• Stand on stable surface and grip gun/lance firmly. Expect the gun to kick back when engaged
1) Never refuel while engine is running or hot. Fuel spilled on a hot engine could result in a fire or
explosion.

monoxide gas;exposure may cause loss of consciousness and may lead to death.
4) Do not use to pump flammable or explosive liquids such as gasoline, fuel oil, kerosene,solvents or
thinners. Pump should only be used with liquids compatible with water blaster component materials.
Failure to follow to this warning can result in serious personal injury, death and/or property damage.
5) Water blaster must be located on a solid level surface. Pump could tip or fall causing serious
injury.
6) Do not hold or suspend pump by means of a discharge pipe. Pipe could break or come loose.
