Safety
ELECTRICAL:
In the USA this machine operates on a standard 15
amp 115V, 60 hz, A.C. power circuit. The amp, hertz,
and voltage are listed on the data label found on each
machine. Using voltages above or below those indi-
cated on the data label will cause serious damage to
the motors.
EXTENSION CORDS:
If an extension cord is used, the wire size must be
at least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.
GROUNDING INSTRUCTIONS:
This appliance must be grounded. If it should mal-
function or break down, grounding provides a path of
least resistance for electric current to reduce the risk
of electric shock. This appliance is equipped with a
cord having an equipment-grounding conductor and
grounding plug. The plug must be inserted into an ap-
propriateoutletthatisproperlyinstalled and grounded
in accordance with all local codes and ordinances.
This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug in
“Fig.A”.A temporary adaptor that looks like the adap-
tor in “Fig. C” may be used to connect this plug to a
2-pole receptacle as shown in “Fig. B”, if a properly
grounded outlet is not available. The temporary adap-
tor should be used only until a properly grounded out-
let (Fig. A) can be installed by a qualified electrician.
The green colored rigid ear, lug, or wire extending
from the adaptor must be connected to a permanent
ground such as a properly grounded outlet box cov-
er. Whenever the adaptor is used, it must be held in
place by a metal screw.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
Check with a qualified electrician or service person if
you are in doubt as to whether the outlet is properly
grounded. Do not modify the plug provided with the
appliance - if it will not fit the outlet, have a proper
outlet installed by a qualified electrician.
Le raccordement incorrect du conducteur de
terre d’équipement peut entraîner des risques
d’électrocution. Vérifiez auprès d’un électricien quali-
fié ou d’un responsable de l’entretien si vous avez
quelque doute que ce soit quant au raccordement à
la terre de votre prise murale. Ne modifiez pas la fiche
fournie avec l’appareil : si elle ne correspond pas à la
prise murale, faites installer une prise adéquate par
un électricien qualifié.

SPECIAL NOTES
The sound pressure level at the operator’s ear was measured to be 72 dBA. This was a nearfield, broad-
band measurement taken on a carpeted floor. This appliance contains no possible source of impact noise. The
instantaneous sound pressure level is below 63 Pa.
The weighted root mean square acceleration at the operator’s arms was measured to be below 2.5m/s2. This was
a tri-axial, third-octave-band measurement made during normal operation on a composite tile floor. The
measurement and related calculations were made in accordance with ANSI S3.34-1986.

Operations
How This Machine Works
The machine is meant for wet cleaning, but can be used for cleaning dry surface with the optional dry filter.
The machine is equipped with a float shut-off. As the tank is filled to capacity, a float rises and seals the vacuum
intake, causing loss of vacuum. Switch off the vacuum when this happens and bring the machine to a floor drain.
To drain the machine use the hose at the back of the vacuum and empty into drain. With both wet and dry applica-
tions be sure to frequently clean the filter. This is especially true when the vacuum is being used with strippers and
wax.

98013230 WET DRY VACUUM 17
Unplug machine from electrical outlet before doing any maintenance.
Débranchez la machine de la prise électrique avant de procéder à la
maintenance.
Daily Maintenance
Strippers and some detergents produce foam which will damage the vacuum motors. The vacuum 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 pull-
ing foam through vacuum motor. Should vacuum motor become wet, remove source of overflow and immediately
run vacuum motor open to dry.
At the end of each working day:
1. After each use, rinse tank with fresh water. Periodically inspect the recovery tank and decontaminate,
using a Hospital Grade Virucide or a 1:10 bleach to water solution. Wastewater should be disposed of
properly.
2. Remove head assembly and allow tank to dry.
3. Remove filter 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
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.
3. Examine carbon motor brushes and commutator.

Maintenance
Servicing the Filter
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 of the filter will not restore vacuum performance.
The filter is accessed by lifting the head assembly off the tank.
Foam filter is easily removed by simply lifting the filter basket out of the tank.
Optional Cartridge filters – Remove the filter retainer by unscrewing the retaining nut and replace with new filter.
