SAFETY INSTRUCTIONS FOR
ENGINE DRIVEN PRESSURE WASHER
a. Petrol or diesel powered engines must
never be used in unventilated closed
spaces. The exhaust fumes produced are
highly toxic and can cause ‘Carbon Monoxide
Poisoning’ which will cause drowsiness and
ultimately death. It is only permissible to run a
petrol engine indoors if the building can be very
well ventilated and the exhaust fumes can be
captured and ducted to the outside through an
exhaust extraction/scavenger system.
b. The Engine/Pressure Washer should
be positioned on a firm level surface. The
wheels should be locked, so that the engine
cannot move during operation.
c. The engine should not be run at speeds
that exceed the maximum speed on
the rating plate. Operating an engine at
excessive speeds increases the likelihood of
component failure and consequent accidents.
d. Do not tamper with components that
regulate the engines speed. You may alter
the factory set running parameters.
e. Use only the type of fuel listed in the
Engine Instruction Manual. Using fuel with
an octane rating less than that specified
can lead to excessive engine wear and
premature engine failure.
f. Keep the area around the engine clear,
clean and tidy. Never allow any combustible
material (timber, plastic, cardboard, canvas
etc) near a running engine.
g. Do not use in or near to potentially
explosive atmospheres. Dust laden
atmospheres as can be found in some
industrial buildings (Flour Mills, Timber Mills)
have an explosive potential.
h. Regularly check the fuel system for
leaks. Hoses and unions should be
checked for deterioration or chafing.
Check the fuel tank for damage or for a
poorly fitting or worn fuel cap. Any defects
must be rectified before the engine is used.
i. Always stop the engine and allow it
to cool down before refuelling. Try to
avoid any fuel spillage (often caused by
‘overfilling’ the tank) and clean up any spilt
fuel immediately. The application of dry sand
is an effective way of neutralising fuel spills.
j. Do not allow the engine to run out
of fuel. Surging of the engine as it uses
the last of the fuel could cause damage to
connected equipment.
k. When transporting the engine in a
vehicle ensure that the fuel tap is turned
off. To minimise the risk of fuel spillage the
engine should be secured by ropes etc to
the load area of the vehicle so that it cannot
move during transportation. The engine
should be secured in as level an attitude as
possible.
l. For long term storage we recommend
that the fuel system of the engine is
drained. During long term storage additives
in modern fuels can precipitate from the fuel
and block jets and valves in the fuel system.
m. Store the machine in a secure and well
ventilated area. Unauthorised personnel
should not have access to this machine.
ADDITIONAL SPECIFIC SAFETY RULES
a. Never point a pressure washer at
yourself or anyone else. The strong jet
from a pressure washer can cause serious
wounds or injury. Such wounds may seem
minor, but medical treatment should always
be sought for any injury as soon as possible.
b. Never attempt to move or push objects
using the power of the jet spray. The
jet spray can throw objects considerable
distances. Thrown debris could strike and
injure others that are in the vicinity.
c. Petrol engines should never be used
inside buildings or other partially enclosed
spaces. Exhaust fumes from petrol engines
are extremely toxic and can cause Carbon
Monoxide poisoning. It is only permissible to
run a petrol engine indoors if the building can be
very well ventilated and the exhaust fumes can
be captured and ducted to the outside through
an exhaust extraction/scavenger system.
d. Operators should wear the appropriate
PPE (personal protective equipment).
Always wear eye protection. Wear safety
shoes. Consider the use of other protective
clothing (gloves, boiler suit etc) as appropriate.
e. Keep bystanders at a safe distance
from the workplace. Debris can be thrown
considerable distances by the jet spray.
Consider roping or fencing off the work area to
keep bystanders and animals at a safe distance.
f. Only allow competent operators to use
this equipment. Operators should have
read and understood the instructions in the
Instruction Manual. Children should not be
allowed to operate this equipment.
