This Wet/Dry Vacuum is double-insulated, eliminating the need for a separate
grounding system. Use only identical replacements parts. Read the servicing
instructions before servicing the Wet/Dry Vacuum.
Use this Wet/Dry Vacuum only as described in this manual.
Observe the following warnings that appear on the motor housing of this
Wet/Dry Vacuum.
WARNING
SERVICING OF A DOUBLE-INSULATED WET/DRY VACUUM
In a double-insulated Wet/Dry Vacuum, two systems of insulation are provided
instead of grounding. This means that no grounding is provided on a double-insulated
appliance, nor should a means for grounding be added. Servicing a double-insulated
Wet/Dry Vacuum requires extreme care and knowledge of the system and should
be done only by qualified service personnel. Replacement parts for a double-insulated
Wet/Dry Vacuum must be identical to the parts they replace. The double-insulated
Wet/Dry Vacuum is marked with the words
“DOUBLE INSULATED” and the symbol may also be marked on the appliance.
•For household use only.
•To reduce the risk of electric shock, unplug before cleaning or servicing.
•DO NOT use without filters in place.
•To reduce the risk of electric shock, use indoors only.
WARNING
If the supply cord is damaged, it must be replaced by the manufacturer or
its service agent or a similarly qualified person in order to avoid a hazard.
WARNING
Remove the plug from the socket before performing maintenance. Before using
the machine make sure that the frequency and voltage shown on the rating
plate correspond with the mains voltage. Specifications and details are subject
to change without prior notice. The accessories shown in the pictures may vary
from model to model.

for extended hours or when using it in a noisy area.

DRY PICK-UP
1. The filter must always bein correct position to reduce the risk of leaks
and possible damage to the vacuum. Make sure that the filter is completely
covering the filtercage. Make sure there are no gaps between the filter
andthe lid. (See illustration). It is very important to assemble the filter
to the cage without allowingany possible leaksor tears. Any leaks will
allow the pickedup debris to be blown out ofthe blower port and back
into the surrounding environment.
2. When using the vacuum to pick up very fine dust, it willbe necessary
to empty the dust tank and clean or replace the filter at more frequent
intervalsto maintain peak vacuum performance. Shake excessdust
NOTICE
A dry filter is necessary to pick up dry material. If you use the vacuum to pick up
If the filter gets wet, replace it before continuing to do dry pickups.

water pipe with screwdriver. Put the exhaust water pipe in the hook of the tank.
Makes sure it higher than the tank.
3. This wet/dry vac is equipped with a float mechanism which will rise automatically
and the motor noise becomes higher in pitch due to increased motor speed.
The liquid capacity may vary with the rate of pickup.
IMPORTANT:
To reduce the risk of damage to the vacuum, do not run motor with float
in raised position.
NOTE:
If accidentally tipped over, the vacuum could lose its suction ability. If this occurs,
to its normal position, and you will be able to continue operation.

1277-027
50L STAINLESS STEEL WET/DRY VACUUM
MAINTENANCE
WARNING
To reduce the risk of injury from accidental starting, unplug power cord before
changing or cleaning filter. The filter should be cleaned often to maintain peak
Vacuum performance. Do not remove filter cage and float. The float prevents
water from entering the impeller and damaging the motor. The cage prevents
fingers from touching the moving impeller.
NOTICE
To avoid damage to the impeller and motor, always reinstall the reusable filter
before using the vacuum for dry pickups and always reinstall the foam filter
before using the vacuum for wet pickups.
After cleaning, check the filter for tears or small holes. Do not use a filter with holes
or tears in it. Even a small hole can cause dust to come out of the vacuum. Replace
it immediately.
Before installing the filter on the vacuum, clean the area of the lid so that the clamp
ring will seal the bag against the lid and stop small particles from bypassing the filter
bag. If the filter is clean and not damaged, replace it on the filter cage. If it cannot
be reused, place a new filter over the filter cage.
Clean the filter in an open area.
CLEANING
To keep the wet/dry vacuum looking its best, clean the outside with a cloth
dampened with warm water and mild soap.
To clean the tank:
1. Dump out debris.
2. Wash tank thoroughly with warm water and mild soap.
3. Wipe out with dry cloth.
STORAGE
Before storing the vacuum, the dust tank should be emptied and cleaned.
The cord should be wrapped and hung on the unit and the accessories should
be kept in the accessory holder so they can be readily available. The vacuum
should be stored indoors.
