POWER BROKER™
POWER ALLOCATION FEATURE
The Power Broker™ feature allows optimal
allocation of the power available between the
dust extractor and power tool.
Before connecting power tool to power tool
outlet, set POWER BROKER™ dial as follows:
1. Get tool amp rating from tool dataplate.
2. Subtract tool amp rating from 15A.
3. Set dial to the difference. Tool amp and dial
setting must not exceed 15A.
Models VAC090S and VAC140S only:
Before connecting tool to the power tool
outlet, make sure the tool rating does not
exceed 5.5A.
Notes:
• The building's circuit breaker can trip if the
combination of power tool amp rating and
the dial setting exceed the building circuit's
amp rating.
• If full dust extractor power is needed with a
power tool that draws high amps, it may be
necessary to plug the power tool into a
separate circuit.
CONNECTING DUST EXTRACTOR TO
POWER TOOLS AND ATTACHMENTS
This dust extractor can also be connected to
various power tools or their attachments to
easily extract and collect dust. Applications
include drilling and demolition of concrete
using rotary and demolition hammers, as well
as sanding various materials using grinders
and sanders. Other power tools that can be
connected to the dust extractor include
routers, planers and saws. To determine if
any attachment and/or adapter is required to
connect a given power tool and dust
extractor hose, consult the Bosch catalog or
website (www.boschtools.com). Depending
on the hose port on the power tool or
attachment, the included VX120 power tool
hose adapter can be either slid into the hose
port or snapped into place. Bosch also offers
a variety of other dust extractor hose
adapters (not included) to allow the hose to
be connected to hose ports of various sizes.

FILTER CLEANING SYSTEM

The Bosch VAC-Series dust extractors have
2 types of filter cleaning systems: automatic
filter cleaning and semi-automatic filter
cleaning. These are very aggressive systems
which maximize filter cleaning to maintain a
high air flow (CFM) rate even in heavy duty
applications.
