The vacuum / pressure pump (FIG.1)
The Vacuum Pump is hand held, accurate, robust
and easy to use. The basic unit consists of a pump-
body(A), moveable handle(B) and a gauge(C) which
displays both vacuum(in HG / BAR) and pressure
(Psi / Bar). Pressure and vacuum modes can be
selected via the mode selector (D) as follows 1. For
vacuum testing-turn the mode selector until the
selection arrow is aligned with operation arrow
labeled “IN” (Fig. 2.1) 2. For pressure testing – turn
the mode selector until the selection arrow is aligned
with the operation arrow labeled
CAUTION
Although the Vacuum Pump is manufactured from high
quality materials to exacting standards, please
remember that it is a PRECISION INSTRUMENT so
please ensure that it is handled accordingly. Dropping,
rough handling, exposure to high temperatures (hot
engines, naked flames, etc) or misuse may jeopardize
the accuracy of the pump and may also invalidate the
warranty.
USING THE AUTOMOTIVE VACUUM & PRESSURE TEST KIT TO DIAGNOSE ENGINE
FAULTS
Before condemning the engine management system for causing any particular problem,
remember that the engine’s mechanical components must be in good condition for the
engine to perform properly. A vacuum gauge can be used to check the mechanical
condition of an engine, however it is not foolproof.
By connecting the pump to a manifold vacuum port (this must be the engine side of the
throttle butterfly) with the T connectors provided, a wide array of diagnostic examinations
can be conducted.
By examining the range of vacuum readings and the movement of the gauge needle in
comparison to the pressure readings of a normal engine running at idle( typically steady
and between 16inHg and 22inHg), it is possible to diagnose a variety of faults.
