OPERATION MANUAL AND INSTRUCTIONS
ISTRUZIONI PER L'USO
• Start the engine and check that idle pressure is about 300 bar. It is normal that it will take some time to start the engine after
the tester has been mounted, which is due to the presence of air inside the tester.
• Even in case the engine should have a problem that prevents it from starting, you should be aware that only with the starter the
pressure should reach 300 bar on the rail.
• Once the engine has started, you can speed it up to check that the pressure rises properly.
TEST RESULT
The most important parameter to test is that 300 bar should be reached with the engine idling or activating the starter. If this
pressure is correct, you can deduce that the low-pressure circuit is working properly and the high pressure pump is supplying
the minimum pressure needed to start the engine properly.
In the event that the pressure is correct but the engine does not start, you should find what the problem is, which will not be the
high pressure pump. The problem could be an electrical fault, injector etc.
If the pressure does not reach the required pressure, follow these steps:
• Test the pressure at the inlet of the pressure pump with a low-pressure tester.
• If the pressure at the pump inlet is correct, you must check the maximum pressure of the pump. (See "Maximum pump pressure
test" section).
PRECAUTIONS TO CONSIDER
• Because you are dealing with very high pressures, you are required to take all necessary precautions to avoid being injured
(wear goggles and gloves, do not disconnect the pipe while under pressure etc.)
• Hoses can withstand high internal pressures; therefore, it is essential not to assemble them in a way that they are strangled or
forced, since they may get damaged if they are mowed internally.
• In common rail injection systems, cleanliness is very important. Before connecting any pipe or hose, check that the tester or
anything else is perfectly clean.
Maximum pump pressure test
Some high pressure pumps disconnect the third piston when low pressure is required. Thus they only work with two pistons,
whereby the engine power requirement is less. The third piston is activated by a solenoid when 600-700 bar are reached.
Once you have verified that the pressure at idle is correct or if there is no pressure on the ramp, proceed to check that the
pressure may rise above 1050 bar, which tells you that the pump is working optimally. To perform this test, the tester must be
connected as shown in Fig. 3; a hose must be connected from the pump outlet to the tester, and the other connection of the
tester must be closed with the metal plug supplied with the tester.
The kit comes equipped with a bottle to collect waste diesel. Connect the pipe to the valve to collect such excess.
When the starter is activated, the pressure should exceed 1050 bar. If that pressure is reached, it means that the pump is
working correctly; otherwise, either the pump or the regulator is damaged.
