Wolo 858 TORNADO User manual

Your purchase of a WOLO TORNADO Air Tank & Compressor is a perfect choice to power your high-pressure
air horns, tools and accessories. The Wolo name, with more than thirty years of experience, is your guarantee
of a superior horn product. If you need help installing this product, our technicians are available to answer your
questions, Monday through Friday from 9 AM to 4 PM EST by calling 1-888-550-HORN (4676).
IMPORTANT: The compressor comes pre-mounted
to the air storage tank. The installer has the option to
separate the compressor from the tank and mount it
independently.
INDEPENDENT COMPRESSOR / TANK MOUNTING
(Fig. 1):
1. If the method of mounting the compressor is to be
independent of the tank, remove the four screws that
secure the compressor to the tank, then disconnect
the braided hose from the tank. You will now be able
to separate the compressor from the tank.
COMPRESSOR and TANK INSTALLATION (Fig. 2):
IMPORTANT! When selecting a mounting location for
the compressor, make sure that the compressor’s
braided hose will be close enough to the tank’s inlet
connection.
COMPRESSOR INSTALLATION (Fig. 2A):
2. Locate a convenient location to mount the
compressor that will be dry. If the location
is the engine compartment make sure
the compressor is safe from the heat of
the exhaust manifold and try to mount
compressor as far to the front of vehicle as
possible to provide optimum airow around
compressor. IMPORTANT! Do not mount
on a plastic fender well, or on exible
material.
3. Using the compressor’s mounting base as
a template, mark the hole locations and
drill to size, use a 3/16” drill bit. Secure the
compressor to the mounting surface using
the hardware provided. (Fig. 2A)
TANK INSTALLATION (Fig. 2B):
4. The mounting location for the tank should
be easily reachable so that the tank
can be periodically serviced, draining
condensation, water from the petcock
located on the bottom of the tank.
5. Use the tank’s mounting bracket as a
template, mark the hole locations and drill
to size 15/64”. Secure tank with hardware
provided.

HOSE INSTALLATION (Fig. 3 and Fig. 4):
6. If the compressor was separated from the tank, connect the
stainless steel braided hose from the compressor to tanks inlet
port. (Fig. 3.) IMPORTANT: Make sure the threaded tting
on the end of the braided hose has either been wrapped with
Teon®tape or coated with pipe sealant to prevent air leaks.
7. Using the high-pressure plastic hose provided, cut to size to
be able to connect the tank to inlet tting of the accessory or
valve requiring high-pressure air. Place the brass nut from the
tank’s outlet tting onto the high-pressure plastic hose. Push
the plastic hose fully onto the outlet tting, tighten the brass nut
onto the outlet tting. (Fig. 4 and 5)
CAUTION: Do not over tighten the brass nut.
8. The other end of the plastic hose is connected to the accessory
or valve requiring high-pressure air.

WIRING COMPRESSOR
(Fig. 7 through Fig. 9):
9. The compressor’s red wire
is connected to a (+) 12-volt
power source, using the fuse
provided.
IMPORTANT! The fuse must
be connected directly to the
power source.
IMPORTANT! The red fused
wire must be connected to
a (+) 12-volt power source
controlled by the vehicle’s
ignition switch. This will
protect your compressor
from running continuously
and being damaged if an
air leak develops when the
vehicle is not in operation.
Suggested connection points
are: blower motor, windshield
wiper motor or the accessory terminal on the fuse panel. Make sure the
connection point has a wire that is as heavy as the compressor’s wires and
the connection point is capable of handling 25-amps. CAUTION: remove
the fuse from the fuse holder until installation is complete.
OPTIONAL: A switch can be installed into the compressor’s red wire. This will
permit the driver to turn-off the system if it is not required. (Fig. 7)
10. The compressor’s black wire is connected to a rubber plug. NOTE: the
rubber plug will have two black wires, both wires will connect to the tank’s
pressure switch.
IMPORTANT: It is recommended that both black wires be pushed forward
so that the terminals are extending out of the rubber boot exposing the 1/4”
female terminals (Fig. 8.).
11. Select one of the black wires with the 1/4” female terminal, connect the
terminal to the pressure switch. Repeat the procedure for the other black
wire. NOTE: There is no polarity, so either black wire can be connected to
either pressure switch terminal (Fig. 8).
12. Push the rubber boot onto the pressure switch (Fig. 9).
13. The black wire with the looped terminal is connected to ground; secure
the wire’s terminal to either the (-) side of vehicle’s battery or under any
metal body bolt. Make sure that the ground connection is free of rust and
paint. NOTE: The compressor is now ready to be used.Install the fuse
back into the fuse holder and the compressor will automatically start.
When the pressure drops below 80 PSI in the tank, the pressure switch
will automatically turn on the compressor. When the tank pressure is
approximately 120 PSI the compressor will automatically turn off. If the
compressor does not shut off after 4 minutes of running time, check all air
hose connections for leaks. Use soapy water or bubble solution on each tting, while the compressor is
pumping. Use a thread sealant if leak persists after tightening.
CAUTION: Do not touch compressor or ttings with bare hands during or immediately after usage, they
will be hot.
IMPORTANT! Compressor is equipped with an internal THERMAL OVERLOAD PROTECTOR. If compressor
should shut off before the tank has been lled to the pressure switch’s turn off pressure, do not attempt to
restart compressor. Allow compressor to cool off for approximately 40 minutes before resuming use.
