OPERATION
4.1.
Follow the manufacturer's instructions for the removal, if required, of the device or hose to be tested. Use cloth or gloves and arm
protection if the system is known to be hot.
4.2.
Connect an air line with known air pressure to the regulator of the tester with the ball valve shut (operating lever at 90° to hose axis).
IMPORTANT! Regulate air pressure in tester to 25psi maximum. Refer to manufacturer's manual relating to the maximum air
pressure of the turbo or other system being tested. Over pressurisation may damage system components. For example the maximum
pressure in most vehicle turbo systems is approximately 15psi (1bar) up to 25psi (1.7bar). A vehicle coolant system is typically rated at
15psi. A graduated approach to leakage testing is recommended.
4.3.
Test Method 1:
4.3.1.
Select the correct air inlet adaptor and plug adaptor (fig.1) by first measuring the hose diameter. Each adaptor has three diameters to fit
different sizes of hose.
4.3.2.
Set regulator of tester to 5psi to check for large leaks with valve open (operating handle inline with the hose axis). and with the air
coupling disconnected.
4.3.3.
Plug the outlet of the system with the appropriate blank end adaptor.
4.3.4.
Connect the inlet adaptor, set at 5psi, to the system inlet.
4.3.5.
Connect the air coupling to check for leaks at the pre-set (5psi). If a leak is identified audibly or if the pressure gauge pointer falls,
it indicates that the system has a fault resulting in loss of pressure. Repair the leak and retest.
4.3.6.
If no leaks are evident, regulate pressure to 10psi and repeat 4.3.5.
4.3.7.
If no leaks are evident, regulate pressure to a maximum of 15psi or to the manufacturer's maximum pressure and retest as in 4.3.5.
If the gauge pointer remains stationary for one minute it will indicate that the system is in good working order.
4.3.8.
Release the pressure in the system by rotating the ball valve lever to align with hose axis.
4.3.9.
Disconnect the quick coupler, clean and return all items to carry case.
4.4.
Test Method 2:
5.4.1.
Set up as in test method 1: 4.3.1 to 4.3.5.
5.4.2.
When the system is pressurized, close the ball valve. By closing the ball valve the system is isolated from the constant air supply. The
system can now be tested to ensure it is holding a constant pressure. By monitoring the pressure gauge over a period small leaks can
be detected, showing as a fall in pressure within the system.

MAINTENANCE
5.1
Always keep the plastic adaptors clean and free of oil and grease. Clean them regularly with a non-aggressive cleaner, ensuring that
components are dry before storage.
Recycle unwanted materials instead of disposing of them as waste. All tools, accessories and packaging should be sorted, taken to a recycling centre
and disposed of in a manner which is compatible with the environment. When the product becomes completely unserviceable and requires disposal,
drain off any fluids (if applicable) into approved containers and dispose of the product and the fluids according to local regulations.
