Bosch 3931A User Manual

Read and understand all instructions. Failure to follow all instructions
listed below, may result in electric shock, fire and/or serious personal injury.

Keep your work area clean and well lit.
Cluttered and dark areas invite accidents.

Do not operate vacuums in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust.
Appliances create sparks, which may ignite
the dust or fumes.

Keep bystanders, children, and visitors
away while operating the vacuum. Do not
allow to be used as a toy. Close attention is
necessary when used by or near children.

The power tool outlet is grounded and the
vacuum must be plugged into an outlet
properly installed and grounded in
accordance with all codes and
ordinances. Never remove the grounding
prong or modify the plug in any way. Do
not use any adapter plugs. Check with a
qualified electrician if you are in doubt as
to whether the outlet is properly
grounded. If the vacuum should electrically
malfunction or break down, grounding
provides a low resistance path to carry
electricity away from the user.

Do not insert objects like paper clips or
screwdrivers into power tool outlet. The
outlet is live when the vacuum is plugged into
power source and switch is set to power tool
activation mode or filter cleaning mode.
Electric shock may occur.

Avoid body contact with grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is grounded. If
operating the vacuum in damp locations is
unavoidable; a Ground Fault Circuit
Interrupter must be used to supply the power
to your vacuum. Electrician’s rubber gloves
and footwear will further enhance your
personal safety.

Don’t expose vacuum to rain or wet
conditions. This vacuum can be used for
picking up non-flammable liquids but it is not

intended to be immersed or submerged in a
fluid. Electric shock may occur.

Do not handle plug or appliance with wet
hands. Electric shock may occur.

Do not abuse the cord. Never use the cord
to carry the vacuum, pull the vacuum or
yank the plug from an outlet. Keep cord
away from heat, oil, sharp edges or
moving parts. Replace damaged cords
immediately. Don’t drive over it or close a
door on it. Damaged cords increase the risk
of electric shock.

When operating a vacuum outside, use an
outdoor extension cord marked “W-A” or
“W”. These cords are rated for outdoor use
and reduce the risk of electric shock. Refer to
Recommended sizes of Extension Cords in
the Accessory section of this manual.

Stay alert, watch what you are doing and
use common sense when operating a
vacuum. Do not use vacuum while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating vacuum may result in serious
personal injury.

Avoid accidental starting. Be sure
vacuum and tool switches are OFF before
plugging in or putting vacuum switch into
power tool activation mode or filter
cleaning mode. Do not keep power tool
plugged into the vacuum cleaner’s power
tool outlet during normal vacuuming.
Plugging in vacuums or tools that have the
switch ON invites accidents.

Do not overreach. Keep proper footing
and balance both for you and the vacuum
at all times. Use extra care when cleaning
on stairs. Proper footing and balance
enables better control of the vacuum in
unexpected situations.

Do not vacuum burning, smoking or
smoldering things like cigarettes,
matches or hot ashes. Fire inside the
vacuum tank may occur.
