Bosch Appliances 3931A Vacuum Cleaner User Manual


 
-9-
If full vacuum cleaner power is needed with
a power tool that draws high amps, it may
be necessary to plug the power tool into a
s
eparate circuit. However, in this situation,
the Power Tool Activation feature cannot be
used.
Switching the Vacuum Cleaner ON
1. Make sure the power tool is switched off,
and then plug it in.
2. Turn the mode selector switch to POWER
TOOL ACTIVATION position.
3. When the power tool is switched on, the
power tool automatically switches on the
vacuum cleaner.
Switching The Vacuum Cleaner OFF
1. When the power tool is switched off, the
vacuum cleaner is switched off.
In order to empty the hose, the vacuum
cleaner switches off after a 6 second delay.
PULSE-CLEAN™ FILTER CLEANING
The vacuum cleaner is equipped with the
electromagnetic PULSE-CLEAN™ filter
cartridge cleaning system, which in 10
seconds allows the unit to self-remove dust
that is adhering to the filter cartridges.
Before using the PULSE-CLEAN™ mode,
we suggest to advise those in hearing
range about the sound of this feature.
PULSE-CLEAN™ MODE
(when no power tool is plugged in)
1. Turn vacuum cleaner dial to PULSE-
CLEAN™ setting.
2.The filter cleaning process will be
automatically completed within about 10
seconds.
3. After PULSE-CLEAN™ cycle completes
itself, the vacuum cleaner will become idle.
4. Switch the vacuum cleaner to the OFF or
ON position, as desired.
See PULSE-CLEAN™ notes below.
PULSE-CLEAN™ MODE COMBINED
WITH POWER TOOL ACTIVATION
The PULSE-CLEAN™ system can also be
used when a power tool is connected and
used with the “POWER TOOL ACTIVATION
MODE”. This is very handy when the location
of vacuum cleaner is separated from the
connected power tool, such as when the tool
is being used up on a scaffold.
1. Make sure the power tool is switched off,
and then plug it in.
2.Plug the power tool into the vacuum
cleaner’s power tool outlet.
3
. Turn the vacuum cleaner dial to PULSE-
CLEAN™ setting.
4. The vacuum cleaner goes into the PULSE-
CLEAN™ mode for 10 seconds.
5.After PULSE-CLEAN™ mode is
completed, switch on the power tool, and
the vacuum cleaner will operate until the
power tool is switched off or disconnected
from the vacuum cleaner.
6. At the time the tool is switched off, the
vacuum cleaner will automatically
determine if the filter needs to be cleaned.
If it determines that cleaning is necessary,
the PULSE-CLEAN™ system
automatically activates, the cleaning
process will be completed within about 10
seconds.
7. After PULSE-CLEAN™ cycle completes
itself, the vacuum cleaner will become idle.
8.Switch the vacuum cleaner OFF, or to
continue working, switch the power tool on
again.
9. If power tool is switched on before the
PULSE-CLEAN™ cycle is complete,
PULSE-CLEAN™ automatically stops and
vacuum cleaner starts to vacuum.
PULSE-CLEAN™ Notes:
The sound of the PULSE-CLEAN™
system may surprise those near the work
area. Before using PULSE-CLEAN™, alert
those in the vicinity of the vacuum cleaner
of this feature and the associated sound it
makes.
Do not keep power tool plugged into
vacuum during normal vacuum cleaning
mode, because any connected power tool
will receive power when vacuum cleaner is
moved from normal vacuum cleaning
mode to PULSE-CLEAN mode.
The PULSE-CLEAN™ system must be
activated when the suction power
decreases to the point of being insufficient.
The PULSE-CLEAN™ system should be
activated regularly to keep the filter
cartridges clean. The proper frequency for
activating the PULSE-CLEAN
system
depends on the type and amount of dust.
With regular usage, the maximum
vacuuming performance is maintained
longer.
