Battery operation
Power Adapter vs batteries
The Wartmann
®
vacuum pump can be operated
with the supplied power adapter, or with batteries.
When the power adapter is plugged-in the
Wartmann
®
vacuum pump will operate on the
power adapter, even when loaded with batteries.
Battery operation is handy at locations with no
power socket available, e.g. when you want to
vacuum a drinking jar whilst traveling.
Placing the batteries
The Wartmann
®
vacuum pump requires six 1.5
volt AA batteries to operate. Hold the Wartmann
®
vacuum pump upside down and unscrew the
battery cover by turning it anti-clockwise.
Inside there is a black battery retainer plate with a
little clip that locks the plate in its position. Unclip
the battery retainer plate on one site and take it out.
The batteries are placed, in pairs, in an opposite
direction to each other. The direction in which the
batteries should be placed is indicated with + and
– markings at the bottom. Place the six 1.5 volt AA
batteries inside.
The battery retainer plate has a hook, opposite the
clip, to hold the plate in its position. Put the battery
retainer plate back by hooking it up on one site.
Then close it and with the little clip lock the battery
retainer plate back in its position. Slightly pushing
the retainer plate in should do the trick. You may
hear a soft click.
Screw the battery cover back on the body by
turning it clockwise. The Wartmann
®
vacuum pump
is now ready to be used with batteries.
Testing the batteries
Press the Power button shortly to test if the batteries
are properly fitted. You should hear the motor
running. If there is no sound, then the batteries are
empty, improperly placed, or of the wrong voltage.
Check the batteries and try again.
Signs of flat batteries
The Wartmann
®
vacuum pump automatically
switches off when the required vacuum has been
reached. When using the Wartmann
®
vacuum pump
and it switches off with the pressure level indicator
not yet being fully green, then the batteries may be
flat. The batteries may no longer be strong enough
to create the required vacuum.
Removing the batteries
The steps for removing the batteries are identical as
for placing the batteries. Just follow the paragraph
about placing the batteries, but instead of putting
batteries in, take them out.
