120 Volt Machine Instructions For Connection
To The Power Supply And The Electrical Ground
This machine must be connected to the electrical
ground to protect the operator from electric shock.
The machine has an approved power cord with three
conductors and a plug with three terminals. Connect
the plug to a receptacle that has three holes and is
connected to the electrical ground. The green (or
green and yellow) conductor in the cord is the
ground wire. Never connect this wire to any terminal
other than the ground terminal.
PLATE
SCREW
This machine uses a 120 volt AC 60 cycle electrical
circuit. Make sure you have the correct frequency
and voltage before connecting the power cord to an
outlet. The machine has a plug as shown in Figure 1.
If a receptacle connected to the electrical ground as
shown in Figure 1 is not available, have one installed
by an electrical contractor. Do not use an adapter.

OPERATION
This machine is a commercial vacuum designed for wet and
dry pick-up.
L N
Dry soil can be vacuumed directly into the tank. To empty the
tank of dry soil, remove the top and dump into trash
receptacle.
For wet pick-up, remove polyester filter. The machine is
equipped with a float shut-off. As the tank is filled to capacity,
a float rises and seals the vac intake, causing loss of
vacuum. Switch off the vacuum when this happens and bring
the machine to a floor drain.
1
ELECTRIC DRAWING
1 – terminal block
2 – switch
3 – motor
Use the convenient drain hose at the back of the vacuum to
empty the tank.
With both wet and dry applications be sure to frequently
clean the filter. This is especially true when the vacuum is
being used with strippers and wax.
2
DAILY MAINTENANCE
Caution: Strippers and some detergents produce foam
which will damage the vac motors.The vac shut-off may
not be sensitive to all foams. Be sure to check that the
tank is not filling with foam. Use a defoaming agent to
avoid pulling foam through vac motor. Should vac motor
become wet, remove source of overflow and immediately
run vac motor open to dry.
3
At the end of each working day:
1. After each use, rinse tank with fresh water.
Periodically inspect the recovery tank and
decontaminate if necessary, using a Hospital Grade
Virucide or a 1:10 bleach to water solution. Waste
water should be disposed of properly.
2. Remove head assembly and allow tank to dry.
3. Remove filters for cleaning or to allow to dry.
4. Inspect hoses for wear. Frayed or cracked hoses
should be replaced to avoid vacuum loss.
5. Inspect power cord for wear. This cable will lay on wet
surfaces. To prevent electrical shock replace cords with
frayed or cracked insulation immediately.

PERIODIC MAINTENANCE
(Every six to twelve months):
1. Check filter for wear, replace dirt saturated filters that
do not respond to normal cleaning.
2. Inspect gasket seals and replace those which have
begun to leak.
Replace both carbon
brushes when either is
less than 3/8" long. (PN S8TOEG845)
3. Examine carbon motor brushes and commutator.
SERVICING THE FILTER
The filter is accessed by lifting the head assembly off the tank.
Polyester filter is easily removed by simply lifting the filter basket out of the tank.
Cartridge filters – Remove the filter retainer by turning the black knob 90 degrees counter-clockwise.
Cartridge filter will then slide off of float assembly.
NOTE:
Be sure to frequently clean the filter.
Allow filter to dry after being used for wet pick-up.
Filters used for wet pick-up including stripper must be thoroughly cleaned before being allowed to dry.
Worn filters can affect vacuum performance. Replace the filter when it becomes worn out and normal cleaning
will not restore vac performance.
SERVICING THE VAC MOTOR
MOTOR REPLACEMENT
1. Disconnect power cord from power source.
2. To access the vac motor, remove the screws that attach the main cover to the head assembly and set
the cover to one side.
3. Disconnect the motor’s 2 red lead wires from the main switch.
4. Disconnect green/yellow wire by removing screw from motor core.
5. Remove the four motor mounting screws.
6. Remove motor plate and set aside.
7. Take out the motor and remove the upper and lower gaskets.
8. Inspect gaskets. If they shown any wear or tear in the material, replace.
9. Install gaskets onto new motor. Make sure gaskets are properly seated.
10. Install the new motor. Make sure foam mufflers are positioned properly.
11. Attach motor plate to motor.
12. Connect green/yellow wire to motor core.
13. Connect motor’s 2 red lead wires to main switch.
14. Re-assemble vac cover.
15. Test for proper operation.

SERVICING THE VAC MOTOR
CARBON BRUSH REPLACEMENT
1. Disconnect power cord from power source.
2. To access the vac motor, remove the
screws that attach the main cover to the
head assembly and set the cover to one
side.
3. Remove the motor cover by removing two
screws. See Figure 1
4. Remove the wire terminal from carbon
Fig. 1

brush housing. See Figure 2
5. Remove the carbon brush assembly by
removing the 2 screws that attach it to the
vac motor. See Figure 3
6. Inspect armature commutator. If it is
extremely pitted, grooved or not concentric
then the motor will need to be replaced or
sent to a qualified service center.
7. Slide the yellow brush housing from plastic
holder. See Figure 4
8. Reverse steps 7 through 4 to install new
brush and housing (part number
S8TOEG845)
