3.2 INSPECTING INJECTOR OPENING PRESSURE
}
Fuel or test fluid discharged by an
injector may penetrate the skin,
seriously harming your health. Make
sure the fuel jet is discharged into a
suitable container.
1. Disconnect the earth lead from the battery
terminal.
2. Remove the fuel injector pipes as a set and
close the connections on the pump units
immediately.
Note:
The opening pressure of the injectors can be
tested using an injector test pump
(DAF no. 0694966). The advantage of this
method is that the injectors need not be
removed from the engine.
3. Check the opening pressure of the injectors.
Instructions for the use of the injector test
pump
1. Before the injector test pump is used, it must
first be bled.
Remove the pump reservoir filler plug and fill
the reservoir with test fluid. The fluid level
must be approximately 1 cm below the top
rim.
2. Tilt the pump until the line with the word
"BLEED" is horizontal.
