use a fine dust filter.
SAFETY GUIDELINES
WARNING!
Servicing of double-insulated wet/dry vacuum.
With a double-insulated wet/dry vacuum, two systems of insulation are provided instead of grounding.
No grounding means 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. Your double-insulated wet/dry vac is marked with
the words ‘double insulated’ and the symbol (square within a square) may also be marked on the
appliance.
EXTENSION CORDS
When using an extension cord with your wet/dry vacuum refer to the following table to determine the
required A.W.G. wire size. Before using the cleaner make sure the power cord and extension cord are
in good working condition. Make repairs or replacements before using the vacuum cleaner. Only use
extension cords that are rated for outdoor use.

will not be captured by the filter and may cause damage to the motor. When vacuuming fine dust use a
fine dust filter (sold separately).
WARNING:
Be sure to read, understand, and apply information entitled “Safety Guidelines”. Do not vacuum in areas
with flammable gases, vapours, or explosive dusts in the air. Flammable gases or vapours include, but are
not limited to: lighter fluid, solvent-type cleaners, oil-based paints, gasoline, alcohol, or aerosol sprays.
Explosive dusts include but are not limited to: coal, magnesium, grain, or gun powder. To reduce the risk
of health hazards from vapours or dust, do not vacuum toxic materials.

REMEMBER! The foam wet filter must be removed after wet vacuuming and
the cartridge filter must be installed before dry vacuuming again.
IMPORTANT:
When vacuuming large quantities of liquids, do not immerse the nozzle
completely in the liquid; leave a gap at the tip of the nozzle opening to allow
air inflow. The machine is fitted with a float valve that stops the suction action
when the collection tank reaches its maximum capacity. You will notice an
increase in motor speed. When this happens, turn off the machine, disconnect
from power supply, and drain the liquid into a suitable receptacle or drain.
To continue vacuuming, refit the power head to the collection tank. After wet
vacuuming, turn the machine off and remove plug from power supply. Empty
the collection tank, clean and dry the inside and outside before storage.

STORAGE
Before storing your vacuum, the collection tank should be emptied and cleaned. The accessories should be
cleaned and stored so they can be readily available when needed. Store the wet/dry vacuum indoors.
REPAIRS
Repairs for this wet/dry vacuum should be performed only by qualified service personnel using only
identical replacement parts.
IMPORTANT:
Clean or change the filter regularly for best performance. ALWAYS USE THE
CARTRIDGE FILTER FOR DRY VACUUMING. If the machine is used without the
cartridge filter, the motor will burn out and the warranty will be voided. Always
keep spare filters on hand.
NOTICE:
The filters included are made of high quality materials designed to stop small
dust particles. The cartridge filter should be used for dry pick-up only. A dry
cartridge filter is necessary to pick up dust. If the cartridge filter is wet, it will
clog quickly and be very difficult to clean. Handle the filter carefully when
removing it for cleaning and replacing it. Check the filters for tears or small
holes. A small hole can let dust pass through and out of the filter. Do not use a
filter with holes or tears; replace it immediately.
