Compressor
The following specication is required for your Racewell Handler:
If your compressor lower capacity than these specication then the Racewell may work slowly.
Manufacturer installation and maintenance guidlines for the compressor should be followed.
This includes checking the oil and draining water from the tank.
Please note: when turning the compressor on or o use the switch on the compressor
and not the switch at the power source.
Attaching the air ttings and connecting the compressor
Connect the air line to the Racewell handler. The connection
is located underneath the Clamp and Weigh Area. If the
compressor is located some distance away from the racewell
handler it is recommended that you include a water trap on the
line to avoid condensation getting to the handler pneumatics.
The image above shows a design for a simple water trap.
Power Supply
Power can be supplied via
mains (110V AC to 240V AC)
or via the 12 Volt battery leads
supplied with the handler. The
internal system is all 12 Volt AC
power supply.

Dashboard controls
Your Racewell handler has a number of dierent operating modes. These are explained below.
(Starting from the Left button on the dashboard)
Power
When power is connected to the Racewell Handler it can then be powered on via the
dashboard power button. When the Racewell Handler is ON the button will glow green. It is
strongly recommended to turn the racewell Handler o when you have nished working.
Draft gates
The draft gate switch will move the postion of the Drafting gates to the left
or right. When Auto drafting the switch must be set to AUTO. The draft gate
direction can be changed at any time during weighing and drafting should you
wish to change the direction manually.
Release button
When set to AUTO the sheep will be automaticlly released from the Clamp and
weigh area when it has been weighed. If set to MANUAL then the operator will
have to press the release button for the sheep to be released.
Tilt
The tilt switch will move the Clamp and Weigh area up or down for access to the
sheep.

Catch (Auto/Manual)
The Catch switch is used if the operator wants to catch a sheep manually rather
than using the eyes on the side of the machine. For general use the switch should
be set to AUTO.
Safety Note: Please ensure the machine is turned o or this switch is set to manual
before adjusting the clamp wall width. Failure to do could result in the clamp being activated and personal injury
Entry
The entry gate has 4 modes:
Closed: The entry gate will remain closed regardless of the sensors on the side
of the Handler. This option is used when you may have sheep in the race and do
not want them to come through the handler.
Auto: The Entry gate will be closed when one of the Blue eyes on the side of the handler are activated.
It will open again when eye is cleared
Auto fast: The Entry gate will be closed when one of the Blue eyes on the side of the handler are activated
however it will open at the same time as the clamp releases allowing for faster ow into the machine
Open: The entry gate will remain open regardless of the sensors on the side of the Handler. This option
is very useful when doing tasks such as treatments and the animals are not being weighed as it provides
continuous ow
Recommended postion is AUTO
Catch
The catch button will activate the clamp. This button is used for catching a sheep
manually. If a sheep is caught in the clamp and the button is pressed again, more air
will ow to the cylinder and increase the pressure on the sheep. If the catch switch is
set to AUTO and you press the CATCH button. It will overide the auto function and the
sheep will not be released automatically.
Hold pressure
The Hold pressure knob increases or decreases the pressure of the clamp wall. The
recommended setting is at about ⁄ if your compressor is running at reommended
pressure of 90100 psi. If set to the lowest pressure the clamp wall will not move at all.
It is important not to have the pressure to high for animal welfare.
Release
The release button will release the clamp. This button is used for releasing a sheep
manually.

Please Note: Wool dust or debris covering any of the four eyes can aect operation.
Make sure that the lenses of the eyes are clean at all times.
Positioning the sensors (eyes)
Blue Eyes These activate the closing of the entry gate to stop the next sheep coming in while
there is one being weighed. The backing hook in the lead up race is also activated
by these eyes.
Black eyes When one of the blue eyes is covered and one of the black eyes is covered the clamp
will activate and a sheep will be caught and weighed. It is important that the eyes are
positioned correct and that a sheep can not get inbetween the Blue and black eyes.
The eyes are on magnets to allow ease of adjustment to suit the size of animals you are working
with or the task your wanting to achieve in the handler.

9Te Pari Racewell HD3, HD4 & HD6 Operators Manual
Racewell HD SHEEP HANDLING SYSTEMS
Anti backing hook
This works with the auto gate, and ensures that the animal
can't walk backwards the handler.
The anti backing hook is activated by the blue eyes and
prevents the sheep moving backwards when it is released. It
is recommended the hook is disabled when doing tasks such
as crutching where the sheep is caught towards the back of
the clamp and weigh area. The hook can be deactivated by shifting the pin position.
Adjusting the clamp and weigh area width
At the bottom of the clamp wall, there are adjustment holes.
Safety Note: Please ensure the machine is turned o or this switch is set to manual before adjusting
the clamp wall width. Failure to do so could result in the clamp being activated and personal injury. It
is also possible to remove the air hoses on the cylinder to make adjustment easier
The width of the clamp and weigh area can be adjusted to suit dierent size animals. Ideal
adjustment will catch the sheep with the clamp wall parellel with the other side and minimise
movment of the clamp wall to catch a sheep.
Size can also be adjusted dierently from front to back if required.
The length of the squeeze clamp wall ram can also be adjusted. In the middle of the moving wall
there are four adjustments for ram length. Adjust the ram so that the clamp wall movement is
minimal to catch a sheep. Ideally the wall is vertical when a sheep is clamped
Adjust this pin so the wall cannot touch the opposite side. This is a safety feature so that hands
and ngers cannot be caught in the empty unit accidentally.
Safety Note: when adjusting for large sheep the wall may be able to touch the opposite side. Be
careful not to activate the clamp without a sheep in the clamp area
Adjusting the lead up race
The lead up race can be adjusted for width at
the top and bottom. A slight V conguration is
best to prevent smaller animals turning around.
Shift pin position

Trouble shooting guide
Please check this trouble shooting guide before contacting customer support, as often
something quite simple could be the problem.
A service charge will be made for call outs if the fault is not covered by your warranty.
When testing the unit without sheep ensure at least one blue an one black eye are covered,
covering either of the blue eyes on their own will only close the auto gate.
For your safety, and that of others, never leave the unit operational when not attended.
