Installing and cleaning Cartridge Filters

1. Unplug vacuum cleaner.

2. To remove fi lter for clean-

ing,  hold  onto  base  of  lid

cage  with  one  hand  and

turn retainer counter clock-

wise to loosen (Fig. 5).

Caution:  Use  care  when

handling  motor  head. 

Dropping motor head may

cause permanent damage. 

3. Remove fi lter cartridge from

motor head (Fig. 6). Handle

filters  carefully  when  re-

moving for cleaning. Even

a small hole can cause dust 

to  be  exhausted.  Do  not

use a fi lter with a hole or

tear. Replace immediately.

4.  Clean the fi lter (Fig. 7):

•Clean a dry fi lter cartridge

by  by  tapping  the  filter

cartridge  on  the  inside  of

a  waste  container  or  by

blowing  loose  dirt  using

exhaust port.

•Clean a wet fi lter cartridge

by rinsing it from the inside. 

Make sure that the fi lter is

dry before using it to pick

up dry material.

When wet (to prevent mold 

and/or  mildew  build-up),

the  cartridge  fi lter  should

be removed and allowed to 

air dry for a 24-hour period 

before being re-installed on 

the fi lter cage.

5.  Slide  clean  cartridge  fi lter

over fi lter cage (Fig. 8).

6. Place fi lter retainer on top

of cartridge fi lter.

7. Hold onto base of lid cage

with one hand and turn re-

tainer clockwise to tighten

(Fig. 9).

WARNING

 

To reduce the

risk of injury, always unplug the tool before 
removing the motor head.

Installing and cleaning foam fi lters 
(some models)

1. Unplug vacuum cleaner.

2. Remove motor head.

Caution:  Use  care  when

handling  motor  head.  Drop-

ping motor head may cause

permanent damage.

3. Remove the foam fi lter sleeve

(and  cloth  filter  if  present)

from motor head.

4. Clean  the  foam  fi lter  sleeve

by rinsing it from the inside.

Make sure that the fi lter is dry 

before using it to pick up dry

material.  Clean  cloth  fi lters

by shaking off loose material

and brushing the fi lter with a soft bristle brush

(Fig. 10).

5. Attach  the  clean 

foam fi lter sleeve to

motor head (Fig. 11)

•If you plan to vacu-

um dry material into a 

fi lter bag, expand the 

paper fi lter bag and fi t 

cardboard collar onto 

the intake port as far

as possible.

•If you plan to vacu-

um dry material and

you  are  using  the

foam  filter  sleeve,

you  must  also  use

the cloth fi lter.

6. Replace motor head 

and snap down tank 

latches.

Vacuuming wet or dry materials  

When vacuuming 

dry materials, ei-

ther the fi lter car-

tridge or the foam 

fi lter sleeve AND 

the cloth fi lter are 

required.  There 

are  other  filters 

that can be used 

with the required 

fi lters  to  provide 

additional  filtra-

tion  when  vacu-

uming  dry  mate-

rial. Follow the the instructions included with these 

fi lters. Empty tank and clean fi lter frequently. Be 

sure fi lters are dry before using the vacuum to pick 

up dry material. Dry material will clog wet fi lters and 

make them diffi cult to clean. 

Starting and Stopping the Vacuum

To  turn  vacuum  cleaner  on,  switch  the  ON/OFF 

switch to the ON position. 

To  turn  vacuum  cleaner  off,  switch  the  ON/OFF 

switch to the OFF position.

For Cat. No. 8936-20:

To turn vacuum on, set the AUTO/OFF/ON switch 

to ON position.

To turn vacuum off, set the AUTO/OFF/ON switch 

to the OFF position. To turn the vacuum on auto-

matically by using a tool plugged into the outlet on 

the motor head, set the AUTO/OFF/ON switch to 

the AUTO position.

Removing liquid from the vacuum tank

1.  Unplug vacuum cleaner.

2. Remove motor head and set aside.

3. Block wheels.

4. Carefully dump contents into fl oor drain. Do not

dump through intake port.

5. Rinse and dry tank.

Do not store vacuum cleaner with liquid in tank. Run 

the vacuum for about 10 minutes without picking

up anything to dry the inside of the tank and the

fi lter cartridge.

WARNING

 If the float is

clean and moves freely and the suction does 
not shut off when tank is fi lled (you will be 
able to see water in the exhaust port), send 
motorhead to the nearest MILWAUKEE service 
facility for repair. 

Using the vacuum as a blower (Cat. Nos. 8950 
& 8955 only)

WARNING

  To reduce the risk

of injury: wear safety glasses and a dustmask 
when using the vacuum cleaner as a blower.

OPERATION

Attaching Caddy and Casters (Cat. No. 8936-20)

You will only need a fl at head screwdriver.

1. Slide caddy over attaching boss’ on bottom of

vacuum cleaner tank.

2. Install screws and tighten.

3. Slide caster housings over attaching boss’ on

bottom of vacuum cleaner tank.

4. Install screws and tighten.

5. Push caster wheel shafts into attaching holes

on bottom of caster housings and bottom of

caddy until they click.

Fig. 4

When  vacuuming  wet  materials,  either  the  fi lter 

cartridge or a foam fi lter sleeve is required. A fl oat 

valve shuts off suction when the tank is full. Be sure 

that the fl oat is clean and moves freely in the fl oat 

cage to ensure that the fl oat valve works. If you 

are vacuuming a large amount of liquid, the fi lter 

cartridge  can  become  saturated  and  a  mist  can 

appear from the exhaust port. If this happens, dry 

the fi lter by running the vacuum (without picking up 

anything) for 10 minutes.

Attach hose to exhaust port on the motor head, 

attach the appropriate accessory to the hose, 

turn the vacuum on.

Using the vacuum cleaner to collect dust cre-
ated by tools 

Many  tools  (such  as  sanders)  are  designed  so 

that they can be used with vacuum cleaners. The 

vacuum cleaners collect the dust that these tools 

create before it gets into the air or onto the fl oor. 

Vacuum cleaners with the AUTO setting are ideal 

for collecting dust because they can be set up to 

turn on and off automatically by using the tool’s on 

and off switch. Vacuum cleaners without an AUTO

setting can also be used to collect dust. The opera-

tor will simply have to turn the vacuum on and off.
