OPERATION
WARNING
To reduce the risk of
injury, always wear
proper eye protection marked to comply with
ANSI Z87.1.
When working in dusty situations, wear appro-
priate respiratory protection or use an OSHA
compliant dust extraction solution.
To reduce the risk of fire and injury, do not use
to pick up flammable or combustible materials.
Empty tank
before use.
Before use, ensure the filter and float cage are
properly installed. Remove dry filter before all
wet pick-up operations.
Starting and Stopping Vacuum
To turn the vacuum on
max run-time mode
, push
the switch to the Speed One (I) position.
To turn the vacuum on
max power mode
, push the
switch to the Speed Two (II) position.
To turn
off
the vacuum, push the switch to the OFF
(O) position.
CAUTION
If the float is clean, moves
freely, and the suction does
not shut off when the tank is filled, contact a
MILWAUKEE service facility for repairs. A mal-
functioning tool can cause personal injury or
property damage.
Wet Pick-Up Operation
For wet pick-up operation, it is recommended to use
the foam filter
(Single pack, Cat. No. 49-90-1990).
1. Remove the battery packs.
2. Remove ALL dirt and debris found in the tank.
3. Remove the high efficiency filter and in-
stall the foam filter (see "Removing/Install-
ing the Filter"). Ensure that the float cage
remains in place.
Float Cage
4.
A float cage shuts off suction when the tank is full.
Be sure that the float is clean and moves freely in
the float cage to ensure that the float valve works.
5. Insert the battery packs.
6. Turn on the vacuum and begin pick-up.
7.
Turn off the vacuum immediately upon completing
a wet pick-up job or when tank is full and ready to
be emptied. If suction shuts off, turn off the vacuum
immediately and empty the tank.
8. Remove the battery packs.
9. To empty the tank, raise the hose to drain any
excess liquid into the tank. Do not use vacuum
inlet to drain contents.
10. Remove motor housing and pour liquid waste into
a suitable drain.
11. Clean the interior of the tank and pick-up acces-
sories periodically, more often when used to pick
up wet, sticky materials. Use warm, soapy water.
Do not store vacuum with liquid in tank.
Automatic Suction Shut-Off
When picking up liquids, an internal float rises until it
seats itself against a seal at the intake of the motor,
shutting off suction. When this happens, the motor
will develop a higher than normal pitch noise and the
suction is drastically reduced. If this occurs, turn off
the vacuum immediately.
NOTICE
Failure to turn off unit after float
rises and shuts off suction will re
-
sult in damage to the motor.
To continue use, empty the liquid waste from the tank.
If the vacuum is accidentally tipped over, it could lose
suction. Turn off the vacuum and return it to an upright
position. The float will return to its normal position.
Installing/Removing Fleece Dust Bag
For increased filter life and ease of cleanup,
use a fleece dust bag to collect fine dust par-
ticles. (Use Cat. No. 49-90-1989 for 0920-20 and
Cat. No. 49-90-1999 for 0930-20, not included)
1. To install, release the tank latches and remove
the motor housing.
2. Lift the dust bag holder up and out to remove
from the tank.
3. Slide the cardboard dust bag inlet in to the dust
bag holder.
4. Insert the dust bag holder back into the slot push-
ing downward to secure in place.
5. Spread out the dust bag in the tank. Replace the
motor housing and secure both latches.
6. To remove, release the tank latches and remove
motor housing.
7. Lift the dust bag holder up and out to remove
from the tank.
8.
Slide the dust bag holder off the dust bag.
9. Pull the cardboard tab until the dust bag inlet
is closed. Dust bag is now sealed and can be
properly disposed.
