Operation; Vacuuming Dry Materials - RIDGID WD1660 Owner's Manual

Operation

To reduce the risk of fire or explosion, do not operate this vac in areas with
flammable gases or flammable vapors such as lighter fluid, cleaners, oil-base
paints, gasoline, alcohol or explosive dust such as coal, magnesium, grain or
gun powder in the air. Do not vacuum explosive dust, flammable or combusti-
ble liquids or hot ashes. Do not use this vac as a sprayer. To reduce the risk of
health hazards from vapors or dusts, do not vacuum toxic materials. To
reduce the risk of electrical shock do not expose to rain. Store vac indoors.
Unplug power cord before changing or cleaning filter or emptying the dust
drum.
CAUTION: To reduce the risk of hear-
ing damage wear ear protectors
when using the vac or blower for
extended hours or when using it in a
noisy area. The operation of any util-
ity vac or blower can result in foreign
objects being blown into the eyes,
which can result in severe eye dam-
age. Always wear safety goggles
complying with ANSI Z87.1(or in Can-
ada CSA Z94-3-M88) shown on Pack-
age before commencing operation.
Safety Goggles are available at many
local retail stores.
To reduce the risk of electric shock, this
appliance has a polarized plug (one blade
is wider than the other). This plug will fit in
a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the
plug. If it still does not fit, contact a quali-
fied electrician to install the proper outlet.
Do not change the plug in any way.
NOTE: When using the unit in the vacu-
uming mode, always insert the air diffuser
in the exhaust port on the detachable
blower. This breaks up the direct flow of
air and diffuses it.
Familiarize yourself with the accessories
included with the vac. Each accessory
may be used in various ways for vacuum-
ing and blowing debris. Here is a list of the
accessories and their uses.
Utility Nozzle - General purpose nozzle
for most vacuuming applications.
Wet Nozzle - Used for wet pickup on
smooth surfaces to pick up liquid and dry
the surface in one stroke.
WARNING
Car Nozzle - Dry pickup nozzle for car
interiors and most upholstery cleaning.
Blower Nozzle - Attached to the end of a
hose or directly to the power assembly
concentrates the air for blowing applica-
tions.
Diffuser - Insert in the exhaust of the vac
while vacuuming and the air exiting the
exhaust is "diffused". This breaks up the
air coming out of the exhaust.
Extension Wands - These wands can be
connected together and provides addi-
tional length for more reach.
Hose - Provides transfer of vacuum or
blowing capability to work site. Provides
the means of attaching extension wands
and nozzles.
Male To Male Adapter - Use this acces-
sory to connect the blower nozzle to the
exhaust of the power assembly.
Accessory Caddy - Store all the acces-
sories with your vac.

Vacuuming Dry Materials

1. The filter must be in correct position at
all times to avoid leaks and possible
damage to vac.
2. When using your vac to pick up very
fine dust, it will be necessary for you to
empty the drum and clean the filter at
more frequent intervals to maintain vac
performance.
NOTE: A dry filter is necessary to pick up
dry material. If you use your vac to pick up
material when the filter is wet, the filter will
clog quickly and be very difficult to clean.
