as soon as possible after working with
chemicals.
Wash hands and face thoroughly before
eating, drinking or smoking.
Provide clean water at all filling sites and on
the sprayer in case of emergency.
Wash & clean respirators regularly & replace
respirator cartridges at recommended
intervals.
Goldacres Equipment
Our equipment uses several materials that
may be harmful to the environment.
Potentially harmful waste used includes such
items as oils and lubricants.
If disposed of incorrectly these can threaten
the surrounding environment and ecology.
Waste products can leech into surrounding
water sources and contaminate the area.
Certain chemicals may be unsuitable for use
with Goldacres standard plumbing designs.
Consult your Goldacres dealer if required.
3 Maintenance Safety
Correct sprayer maintenance is an important
part of eliminating the risk of incorrect spraying
applications and ensuring overall safety.
Always maintain the sprayer to ensure it is in
good working order for its next use.
Keep the sprayer clean - inside & out to
minimise wear and allow easier recognition &
identification of problems that might arise.
Hydraulic Inspection, Adjustment
& Repair
Periodic inspection & assessment of
hydraulic systems and especially hoses is
recommended and should include:
1 The age of hoses
2 Condition of hose fittings
3 Rub marks and potential wear points from
hose contact
4 Unexplained hydraulic oil leaks
5 Excessive corrosion of fittings
If any faults are found, do not operate the
machinery until the issues have been rectified.
Safety – Essential Risk Management
Where practicable, all inspections and
maintenance/servicing work should be
conducted by a person competent in
hydraulics systems and maintenance,
including testing & commissioning.
Maintenance and routine checks should be
conducted to ensure adequate hydraulic fluid
levels and filter cleanliness are fully maintained.
Manufacturer’s recommendations should be
adhered to as excessive or inadequate fluid
levels can cause system failure and present
serious risks.
Injury Risks
Encumbent with all sprayer maintenance is the
risk of injury from:
Cuts, Stabs & Punctures:
• When servicing a machine, be mindful
of sharp edges on parts such as
trimmed cable ties, hose clamps, cut
reinforced hose, edges of plates and
brackets as they may cause cut, stab
or puncture injuries.
Crush Hazards:
• Never attempt maintenace on axles,
wheels or components within the
vicinity of the wheels with the engine
running.
• Never attempt to do maintenance
under any hydraulically raised boom or
structure.
Pinch Hazards:
• When operating moving components
such as a boom, access ladder or
other components. Keep fingers and
hands away from potential pinch
points.
Burn Hazards:
• Hydraulic oil increases in temperature
with pressure and use
• Components may be very hot to touch
and could result in contact burns
• Oil leaks may spray hot oil and cause
eye injury & burns
2

16 GA8701871 REV 00 JANUARY 2023
Essential Risk Management - Safety
• Avoid contacting the hydraulic
tank and all hydraulic lines when at
operating temperature.
• Full coverage clothing minimises the
risk of oil burns and is recommended
with this type of equipment.
Injection Injury
• Injection injuries occur when a jet of
hydraulic fluid pierces the skin and
enters the blood stream.
• This may occur if a hydraulic line
is pierced or damaged. Be aware
that injection injuries are extremely
dangerous and have the potential to
cause death.
Hose Whip/Striking
• Hose whip or striking injuries may
occur when an unrestrained hose
releases oil pressure quickly causing
whipping back & forth until the oil and
energy is fully released.
• The most common point for failure in a
hydraulic hose is at the fittings, where
corrosion and stress related damage is
most likely to occur.
Fluids Under Pressure
Fluids escaping from high pressure lines can
cause serious injury to skin. High pressure
hydraulic oil can easily penetrate human skin.
Do not disconnect any hoses, nozzles or filters
while equipment is operating. Disconnecting
these components while under pressure may
result in uncontrolled fluid discharge which
may be hazardous.
Pressure in the fluid lines must be released
before any maintenance is undertaken.
Be mindful of the location of pressurised lines
in the vicinity of the work area when using
equipment such as grinders, oxy torches and
welders.
Such equipment poses two major risks:
• Equipment may easily cut through lines
• Heat generated may cause line to
rupture and/or burn.
Ensure all fittings and lines are fully/tightly
secured before re-pressurizing after repairs.
Pumps, Pressure Lines & Valves
It is important that the liquid flow systems
of this sprayer are understood and well
maintained because liquids under pressure
create serious risks of injury.
Pressurised spaying and hydraulic systems
operate at pressures up to 20 bar (284 psi) for
spraying and (3000 psi) for hydraulics.
To avoid risks of injury, it is important to:
• Read and understand the operator’s
manual
• Never undo fittings, cut hoses or
carry out maintenance when a pump
is running or when a system is under
pressure
• Do not exceed maximum pressures as
stated in operators manual.
Stored Energy Hazard
Even when a machine is not running, energy
can be stored in components such as
hydraulic accumulators, air tanks, tyres, air
hoses and springs.
Hydraulically supported components such as
the boom center are also a source of stored
energy.
Before working on the machine, ensure that
these parts are relieved of their energy in a
safe manner.

Safety – Essential Risk Management
Lifting a Sprayer
Before raising a sprayer off the ground:
• Ensure that the boom is in its closed
position.
• Park on a flat level, firm area.
• Empty the spray tank where possible.
• Chock all wheels that remain on the
ground.
• Securely lift the sprayer using a rated
jack and support the machine on work
stands.
• Do not work under the machine when
supported solely by a jack.
• Do not support the machine using
materials that may crumble.
Changing Wheels & Tyres
An experienced person with the correct
equipment should mount the wheels on the
sprayer.
When changing a wheel on the sprayer ensure
the machine is on firm level ground and the
opposite wheel is chocked.
Tyre Maintenance
Maintain correct tyre pressure at all times.
Inflation of tyres above or below the
recommended pressure exerts additional
pressure on the tyre, which may result in tyre
damage.
Extreme caution is required during the inflation
of tyres. Rapid inflation of a tyre may cause
separation and/or explosion of the rim. Such
an event can inflict serious or fatal injuries to
the operator of close bystanders.
Always use a tyre inflation gauge.
Be pro-active and continually check the
condition of your tyres during operations.
Do not weld, heat or modify a tyre rim.
Working Heights above Ground
Please contact your local government on the
restrictions and safety requirements needed to
operate at various heights above the ground.
Do not climb on machine to get access. There
is a risk a falling if a person has climbed onto
the machine.
Use ladder or work platform to get access
to parts or areas of the machine above local
government restrictions.
Working On or Underneath the
Sprayer
When working on or underneath a sprayer,
always take measures to make sure that the
sprayer cannot move.
Never get underneath a suspended machine
or suspended part of a machine.
If you must work under the machine ensure
the machine or machine part is solidly
supported.
2
Never get underneath a suspended machine or suspended
part of a machine.
Only rated and approved equipment should be used to lift
and support the Prairie Special 2 sprayers.
Failure to follow these instructions may result in injury.

The surface of the sprayer platform has raised
portions or grip tape to minimise the risk of
slipping.
Keep platform surface clean of mud and other
material to avoid risks of slipping.
Main Spray Tank
Danger – The main spray tank is a confined
space and you must not enter because the
lack of oxygen and chemicals can cause
asphyxiation and death..
Do not enter the tank for any purpose.
Entanglement Hazard
Rotating drives can cause serious injury or
even death when entanglement occurs.
Keep hands, feet, hair and clothing away from
all moving parts to prevent injury.
Never operate a machine with covers,
shrouds, or guards removed.
Decals
Decals are an important part of making
operators aware of risks and correct
operations.
Understand the safety decals and their
purpose to assists the safe operation of your
machine.
It is the responsibility of the owner operator to
replace damaged and/or missing decals.
All decals on the sprayer must be maintained
in good order and replaced if damaged or
missing.
Regularly review decals with operators. It is
very important to ensure that all new machine
components and replacement parts include
current hazard identification decals.
Decals have a part number to assist in their
identification & replacement.
Replacement decals can be ordered from your
Goldacres’ dealer.
Part numbers and descriptions of the decals
on this machine can be found In the Part
Manual on the Goldacres website.
Safety Guards
All safety guards should be replaced if
damaged to ensure that risks of injury are
controlled as intended.
