IMPERIAL TRUCK MOUNTED VACUUM TANKER MANUAL
WARNING:
When entering a transport, septic, or
holding tank, always have someone standing by to
provide assistance, and always have a respirator that
supplies grade D breathing air or a self-contained
breathing apparatus on hand for them. In the event
of an attempted rescue, this equipment is necessary
to prevent death of the rescuer.
WARNING
: Attach a safety-harness and rope to
any person that enters a transport, septic, or holding
tank. Have the safety-harness rope held by a person
standing by to provide assistance outside the tank. An
attempted rescue without the advantage of a rope
and harness can be life threatening to the rescuer.
WARNING
: Entry into a transport, septic, or
holding tank is confined space entry. Persons
entering these tanks for any purpose must be
trained in and follow OSHA confi ned space safety
procedures.
To replace the wear-plate, unbolt the six 1/2”-1NC
hex head screws that fasten it to the collar on the
standoff pipe. Have replacement fasteners on hand
in case any of the existing ones are damaged during
removal. Aluminum tanks require stainless steel
fasteners and steel tanks use zinc plated fasteners.
Along with each hex head screw and nut, use two
fl at washers and one lock washer.
In addition, aluminum tanks use a gasket between
the standoff collar and the wear-plate to separate
the dissimilar metals used in the two. It is a good
idea to have a replacement gasket on hand when
changing the wear-plate on these types of tanks.
Replacement wear-plates can be obtained through
Imperial Industries, Inc., P.O. Box 1685, Wausau, WI
54402-1685, Phone 800-558-2945.
Lighting Devices
Lighting devices referred to under this section
are those built into your Imperial Vacuum Tanker
equipment. For instructions on chassis-cab lighting
devices, refer to your OEM vehicle manufacturer’s
operation/maintenance manual.
Standard lighting devices on your Imperial Vacuum
Tanker include stop/turn-signal/tail lamps, backup
lamps, identifi cation lamps, and license plate lamps.
The stop/turn-signal/tail lamps and the backup
lamps are built into the step bumper at the rear of
the tank. The side-marker lamps are built into the
side of the step bumper and into the rails of the hose
platforms. Finally, the license plate lamp and bracket
is usually mounted at the base of the step bumper.
The stop/turn-signal/tail lamps, backup lamps, and
side-marker lamps have a sealed beam design, which
makes replacement easy (Figure 4.7). To replace these
lamps use the following procedure:
