 NOTICE
The handling of Cationic Emulsions (CRS-2, CMS-2, CSS-1 and CSS) may
create an environment within the Asphalt Distributor that can be corrosive to
carbon steel and cast iron.

• Cationic Emulsions are widely used within the industry.

• Cationic Emulsion is manufactured with asphalt, water, emulsifiers and
hydrochloric acid. The chemistry of individual emulsions varies in asphalt
content and Ph levels.
• Tanks and spray mechanisms used with Cationic emulsions may experience
corrosion
• It is believed the chemistry of the emulsion - specifically the residual fumes
promote the corrosion
• Etnyre Distributors are compatible with Cationic Emulsions provided that
certain precautions are taken.
• Prior to placing a distributor in to service with Cationic Emulsion, it should be
loaded with an AC or MC type material to develop a protective coating.
• Periodic inspection of the tank and spray system should be preformed in the
normal course of operation.
• It is recommended that distributors used in Cationic service be flushed
periodically and at the end of the season with an AC, MC or cutback to
remove the corrosive materials and to provide a protective coating.
• Increasing the quantity of flushing material during daily suck back and
cleanout operations will also help to minimize corrosion damage.
• Dilution is the solution.
• Additional information can be acquired from your Emulsion supplier as well as
the Asphalt Institute or the Asphalt Emulsion Manufactures Association.

WARNING
Take extra care and follow recommended
procedures when alternating asphalt materials
especially when loading hot product, over 212
degrees Fahrenheit (100 degrees Celsius), on
to a tank and system previously in Emulsion
service.

 General Safety Instructions
The operation of a bituminous distributor normally requires handling of liquid products at elevated temperature.
Also, these liquids may be of a volatile nature. A heating system is supplied to raise or maintain the product
temperature, and these systems use highly combustible fuels. As with any type of construction equipment,
there are certain hazards associated with careless or improper operation.
Safety warnings have been provided to call attention to any potentially hazardous situation that may cause
property damage, personal injury or death to the operator or bystanders. These safety warnings will be shown
at various times throughout this manual, as they are applicable to the subject being presented. These safety
warnings are identified by the following warning symbols:

Safety Precautions, Hazard Seriousness Level

You will find safety information boxes throughout this manual. These boxes contain information alerting you
to situations or actions to avoid.
Signal words (DANGER, WARNING, and CAUTION) are used to identify levels of hazard seriousness. Their
selection is based on the likely consequence of human interaction with a hazard. Definitions of hazard levels
are as follows.

DANGER - Immediate hazards which will result in severe personal injury or death.

WARNING - Hazards or unsafe practices which could result in severe personal injury or death.

CAUTION - Hazards or unsafe practices which could result in minor personal injury or product or
property damage.

All of these warnings are listed below and they also appear throughout the manual. In addition to these, you
will find notes throughout the manual.

NOTE - A note provides general information that the operator should be aware of when performing an
operation.

WARNING
To prevent possible burns to operators or

WARNING Figure 12. Using the Measuring Stick

To prevent an explosion or fire hazard, keep

burning cigarettes or other sources of combustion

WARNING
To prevent burns, always wear eye

working around the Distributor.

Check Strainers
Before removing the load line cap or strainer

ensure that there is not material in the strainer box.
Finally ensure that the tank valve(s) are closed and
the POWER switch is OFF before removing the
load line cap and stainer access cover.
Ensure that both the fill line and the suction
strainers are clean and properly installed.
Ensure that all connections on the Distributor are

Before emoving the fill line cap, make

certain that the asphalt pump is turning and

the suction valve is closed.

Fluid contaminant profile requirements for Etnyre
hydraulic units have been determined empirically
based on measuring fluid quality in successful
application, and in laboratory tests designed to
evaluate hydraulic unit contaminant sensitivity.
General contaminant levels have been developed
based on this experience and are shown in Figure

The machine should clean up during a relatively
short period of normal operation to meet the oil

that meets Curve A will provide the user with a

should be met in systems exceeding the continuous
