CORDLESS WET/DRY VACUUMS
OPERATOR'S MANUAL
TO REDUCE THE RISK OF INJURY, USER MUST READ AND UNDERSTAND OPERATOR'S
MANUAL.
•Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
•Vacuum cleaners have motors and other parts
that can produce sparks during normal use. Do
not use within 30 feet of areas where explosive
materials may be present (such as gasoline pumps
and places where liquids like paint thinners, clean-
ers, solvents, etc. are stored).
•Do not use in the presence of explosive dust,
liquids or vapors.
•Do not use where oxygen or anesthetics are
used.
•Do not allow to be used as a toy. Close attention
is necessary when used by or near children.
•Use extra care when cleaning on stairs.
•Wear electrically insulated footwear, such as
rubber boots, when vacuuming wet material.
•Do not handle battery pack or vacuum with wet
hands.
•
Do not pick up soot, cement, plaster or drywall
dust without filter in place. These are very fine
particles that may affect the performance of the
motor or be exhausted back into the air.
•To reduce the risk of health hazards from vapors
or dust, do not vacuum toxic, carcinogenic or
other hazardous materials such as asbestos,
arsenic, barium, beryllium, lead, pesticides or other
health endangering materials.
•WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause can-
cer, birth defects or other reproductive harm. Some
examples of these chemicals are:
•lead from lead-based paint
•
crystalline silica from bricks and cement and other
masonry products, and
•arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
speciallydesignedtofilteroutmicroscopicparticles.
•Do not use your cleaner as a sprayer of flam-
mable liquids such as oil base paints, lacquers,
household cleaners, etc.
•Use special care when emptying heavily loaded
tanks.
•To avoid spontaneous combustion, empty tank
after each use.
•
Do not leave vacuum unattended when battery
pack is installed. Remove battery pack when not
in use and before servicing.
•Do not put any object into openings. Do not use
with any opening blocked; keep free of dust, lint,
hair, and anything else that may reduce air flow.
•
Maintain vacuum. Check for misalignment or
binding of moving parts, breakage of parts and
any other conditionthat may affectthe vacuum's
operation. If damaged, have the vacuum re-
paired before use. Many accidents are caused by
poorly maintained tools.
•Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
•Turn off all controls before removing battery
pack.
•Remove battery pack whenever motor head is
removed from tank.
•Before using the battery pack or charger read
the operator’s manuals, and any labels on the
battery pack, charger and vacuum.
•Recharge only with the charger specified by the
manufacturer. Achargerthatissuitable for onetype
of battery pack may create a risk of fire when used
with another battery pack.
