1Introduction
1.1 Overview
1.1.1 Description of the Scraper
The Toomey scrapers are earthmoving machines designed to be hitched to the back of a tractor
corresponding to the size of the scraper. The scraper consists of 6 main sub-assemblies: The
drawbar (connecting scraper to tractor) the front cross beam with ripper assembly, the two side
walls, apron, the rear frame with bowl and ejector and the swing-arms with rockers and wheel
assemblies. The drawbar is connected to the front cross beam with two pivot pins and a hydraulic
cylinder connected to an accumulor to act as a form of suspension. Ripper legs are connected to
a ripper bar which is connected to the front cross beam via 4 linkages. The ripper bar is raised and
lowered via 2 hydraulic cylinders. The side walls are bolted to the flanges on each side of the
front cross beam and connected to the rear frame via two pivot pins. The apron is connected to
the side walls by pins and bearings and is activated by two hydraulic cylinders secured to the
front cross beam. A cutting blade is attached to the mouldboard in the rear frame in front of the
bowl. There are also side cutting blades mounted to the bottom of the side walls. There are two
hydraulic cylinders which connect the rear frame and the side wall; these control the height of
the cutting blade above the ground. The bowl hinges off the mouldboard and is lifted and
lowered by two hydraulic cylinders mounted to the rear frame. In the bowl is a swing door
ejector which is hinged at the top of the bowl and is operated by two hydraulic cylinders
mounted to the bowl. The right and left swing-arms are connected to the rear frame by four
pivot pins and their height is controlled by two hydraulic cylinders. The swing-arms mount the
rocker assemblies and axles which rotate with use of spherical bearings and whose rotation is
limited by stops on the swing-arms.
1.1.2 Utilisation
This design of the scraper makes it capable in a wide range of applications. The primary function
of the scraper is to shift dirt, whether it is large loads to shift bulk dirt or final trimming to get flat
paddocks or haul roads. The inclusion of rippers in the design allows the scraper to rip hard
packed, difficult to load ground without having to utilise a separate machine. The design of the
ejecting and tipping bowl allows the scraper to work in wet sticky environments and still be able
to unload when required. The large tires reduce ground pressure and allow the scraper to roll
across soft soils without leaving large trenches. The centre lift geometry and walking beam style
wheel arrangement allows the scraper to trim at greater speeds and with a superior finish.
1.1.3 Only use Genuine Parts
Always use genuine part for all repairs. The use of non-genuine parts may adversely affect the
operation of the scraper. It may also void the warranty and exclude the manufacturer of any
liability in case of accidents.
Modifications not authorised in writing by the manufacturer or importer can harm operation or
the safety of use.

2.1 Overview
2.1.1 Warning
If not used correctly, this machine may result in serious injury or death. It is the responsibility of
the owner and operator to read and familiarise themselves with the manual prior to
commissioning the machine. The operator must obey all safety instructions in this manual and
any workplace or government mandated safety regulations relevant to the region the machine is
operating in.
An operator who has not read and understood this manual is not fit to operate this machine. It is
essential to read the safety instructions and understand the safety symbols in the manual. The
safety symbols on the machine must be kept in good condition and be replaced if they become
damaged or hard to read. The operator and person providing training must ensure that the
conditions the machine is to operate in and around are safe.
Additional copies of the manual can be obtained from your distributor or from Toomey
Earthmovers directly.
2.1.2 Meaning of Signs
The operators attention is drawn to the decals applied to the machine. The symbols indicating a
risk are shown inside a triangle. In addition to symbols which confirm to European standards, the
words “DANGER”, “WARNING”, and “CAUTION” may appear on the machine.
“DANGER” and “WARNING” indicate the presence of an immediate danger nearby.

2.3 Safe Operation
2.3.1 Rules for Safe Operation
Personnel safety is number one priority. You can replace a machine but you cannot replace a
human life. Many accidents can be avoided by implementing better training or being more careful
when operating the machine. Following the instructions in this handbook will help avoid
accidents. Observe any site rules, Health and Safety rules or governing codes of practice of the
regions which the machine is to operate. Please be aware of the following points:
xImmediately replace any safety symbols on the machine that are damaged, hard to read
or possibly not present
xDo not allow the operator to drive this machine before they have read this operator’s
manual and understood the significance of safety and acquired any licenses required to
do so.
xThe tractor being used to tow the Scraper must have a ROPS (Roll Over Protection
System) and a seat belt
xThe operator must always wear a seat belt
xUnder no circumstances shall a child drive this machine
xNo passengers are permitted on the tractor unless it is fitted with a passenger seat and
seat belt
xThe safety instructions must be reviewed in a meeting with all operators at least yearly
xNever modify the machine without expressed agreement of the manufacturer or its
importer
xLeave sufficient space when operating around other machines or equipment
xNever operate the machine under the influence of drugs or alcohol
xKeep guards attached to the machine in good condition and replace them if they become
damaged
xIt is important to have prior experience with the scraper (or equivalent scrapers) or be
under instruction before operating the machine.
xConsult your doctor if taking medication that may affect your ability to drive heavy
machinery
xDo not use a mobile phone while operating the machine. Park in an area away from
activity before using your mobile phone.
xBe aware of the limitations of capacity and performance of the tractor and scraper and
do not exceed them. In particular, pay attention to the stability of the tractor and scraper
and how the centre of gravity is affected by the load. Be especially careful when
operating on slopes, uphill and downhill, when the scraper is loaded and unloaded.
xWhen parking the machine, position tractor and scraper on firm level ground. Lower the
scraper so it is resting on the ground. Position the tractor and scraper so that the tractor
can easily drive forward and away from the scraper in the event that the scraper is to be
disconnected.

4500B USER HANDBOOK

2.3.2 Operator Training
Safety must be your priority for all staff working in and around the machine. There is only a
certain amount that can be done when designing a machine to operate safely. The safety of the
operators and those around them is heavily dependent on the behavior of the operators and
maintenance crew. It is the responsibility of the machine owner or the head of the company who
owns the machine to ensure that all the operators of the machine have read and understand the
safety instructions outlined in this document.
Prior to training the instructor must locate the tractor and scraper safety devices. The machine
must be parked in a secure location and using the manual, identify the hazards and risks to a
person who would be in the danger zones.
The instructor must be familiar with the hydraulic controls in the tractor. The instructor should
have knowledge of the site the machine is to be operating on and understand the difficulties
likely to be encountered, ground conditions, slope, obstacles etc. The instructor will need to have
work instructions or a plan to run through with the operator and demonstrate the functions of
the machine and how they achieve the goals outlined in the work instructions.
Train all new operators and encourage then to converse with other machine operators about the
safety of the machine. Only properly trained operators who have demonstrated competency in
understanding the safety requirements and also the function of the machine may be allowed to
operate the machine. Anyone who has not read and understood the safety and operating
instructions shall not be able to operate the machine as they expose themselves and other to the
risk of serious injury or death.
Make a list of all operators who have been trained to operate this machine. It is the responsibility
of the owner to appoint a trainer who will train and approve all operators.

2.4 Dangerous Situations
Please find below a list of the most dangerous situations and the actions that must be taken
upon identification of the situations
2.4.1 High Pressure Hydraulic Fluid Leak
Following the leak or rupture of a hose, a jet of hydraulic oil under
pressure can penetrate the skin causing severe injuries. To avoid this
risk, the operator must de-pressurise all circuits from the tractor. The
tractor manual will instruct how to do this.
When working in close proximity to the machine, consider de-
pressurising circuits unless it is necessary for them to remain
pressurised.
If you suspect a leak, use a piece of cardboard to locate the leak.
Always wear protective clothing (gloves, full length shirt etc) and eye
protection.
If an accident occurs, call the local emergency services.
2.4.2 Accumulator
The hydraulic accumulator which powers the cushion hitch cylinder
sustains pressure in the system even when the tractor hydraulics are
disconnected. See the section in the manual covering maintenance and
repair procedures.
2.4.3 Storage and disposal of waste
Be careful of the environment; consider using appropriate containers
to recover the liquid and used materials. Make sure they are stored and
removed in accordance with local laws and regulations.
2.4.4 Working near hydraulic circuits
Take extreme care when welding, brazing or using an open flame near
hydraulic circuits. The pressurised fluid escaping through a leak can
ignite and cause serious burns and potentially be fatal.

4500B USER HANDBOOK
Page 14
2.4.5 Machine Startup
Before you start the machine or activate the controls, make sure that
nobody is near the tractor or scraper. Honk the horn before moving the
machine.
2.4.6 Falling Objects
Regularly remove debris, clods and stones that can get stuck around
the machine. This makes identifying oil leaks or structural damage
easier to identify. Removing the debris around the hydraulic lines
helps to increase their life by reducing the likely hood of corrosion
and wear due to vibrations.
2.4.7 Pinch or Crush
The apron, bowl and ejector all pose a high thread of crushing or
pinching. These risks could cause serious or even fatal injuries. For
more information, refer to the section of the manual covering the
implementation of the safety devices before starting work on the
machine.
The connection of the tractor and scraper will typically require the
presence of an assistant. Never allow them to be directly behind the
tractor, always remain to the side and in view of the tractor operator
so that they don’t not have the ability to be run over by the tractor or
crushed between the tractor and scraper. For more information refer
to the section of the manual which covers the connection and
disconnection of tractor and scraper.
2.5 Safety Equipment
2.5.1 Description of Safety Equipment
When conducting operations and maintenance procedures of the tractor and scraper, always
wear appropriate clothing and safety equipment:
xDo not wear loose clothing as they could get caught in the moving parts
xWear a safety helmet
xWear safety glasses (Maintenance)
xWear steel capped footwear
xThe operator must wear hearing protection according to the regulations according to
the noise level generated by the tractor
