The Pump; Using The Pump - Mityvac MI8000 Benutzerhandbuch

The vacuum pump is an extremely versatile service
tool that can be used to test a variety of automotive
systems and perform a number of useful tasks.
Though the pump has obvious uses for testing
various vacuum motors, control valves and vacuum
sources, its applications don't end there. Almost any
part or system that requires proper sealing vacuum
to operate can be tested with the vacuum pump. The
pump and its accessories also transfer fluids, help
to bleed brakes and aid in other tasks. The pump
also meets diagnostic tool requirements when such
tools are specified for some state vehicle inspection
programs.
This section will describe the pump, give specifica-
tions, tell how to use the pump and provide some
service tips to help you keep your pump in tip
top-shape.
DESCRIPTION
The hand-held vacuum pump is simple, accurate,
easy to use, and has many applications. It consists
of a pump body, moveable handle, vacuum gauge,
and connection fitting. The pump is easily held in
your hand, and when the handle is squeezed, vac-
uum is produced at the front fitting. If the front fit-
ting of the pump is connected to a closed container
or system, the gauge will show the vacuum level.
VACUUM RELEASE
The vacuum can be released by lifting up on the
Release Lever. This action allows air to enter the
system, thus relieving the vacuum. Vacuum will also
be released when the hose is detached from
the front fitting.

USING THE PUMP

The pump is simple to use. In most cases, it's at-
tached directly to a component, used in place of a
vacuum line or connected into a vacuum circuit with
a tee connector. The pump can be operated as a test
instrument in two ways:
1) When vacuum is desired for a test, the movable
handle of the pump is simply squeezed with your
hand, as in clenching your fist. Continue strokes
until desired vacuum is indicated on the gauge.
2) The pump can be connected into a vacuum circuit
and used to measure existing amounts of vacuum,
just as any vacuum gauge would be used. When
used this way, do not pump the handle, or incorrect
readings may result.
PROPER CARE
Your pump is a sturdily built, precision test
instrument. Do handle it carefully! Don't drop or
handle roughly as the gauge accuracy may be
affected. Care for your pump and it will give you
years of trouble-free service.
LUBRICATION
The factory-installed lubricant is silicone oil and
should provide very long service. If you find it
necessary to lubricate your pump, use silicone oil.
If unavailable, you may use DOT 5 (not DOT 3)
silicone-based brake fluid or a salad vegetable oil.
Do not use petroleum based fluids or spray
lubricants (WD-40, motor oil, etc.), as these will
damage the pump.
