5.4 Altitude Compensation System (46200EB, 46200SB Only)
This unit may be equipped with an Altitude Compensation System. If so, there will be a small boxed
housing mounted to the right and aft of the engine. The system is automatic during most operating
conditions. However, if the machine is taken from above or below an altitude of 2,624 ft. (800
Meters) while the engine is running, the engine will need to be stopped and then restarted. There is
a yellow indicator light that illuminates when the machine is above 2,624 ft. (800 Meters) indicating
that the system is active.
5.5 About the Heated Hose, Wand, Valve, and Tip Guard
The Heated Hose
The heated hose supplied with the machine is Teflon-lined with steel over braid. It has a heating
element, which runs the length of the hose to heat the material within the hose. The hose is
covered with high temperature, durable rubber.
The Wand
The wand has an aluminum tube to protect both the wand and the operator. The pistol grip actuator
is equipped with an electric switch which, when depressed, sends a signal to actuate the pump.
The wand is equipped with a trigger lock to prevent accidental pump actuation when it is not
pumping material.
The trigger must be in the “LOCKED” position at all times except when
intentionally pumping material.
The Valve
The wand has a disposable duckbill valve on the end, which shuts off the flow of material when the
pump is turned off and prevents excessive dripping of material. This valve also directs the material
into a stream for easy application into the crack. Other sealing tips are available. See
for other sealing tips and options.
Tip Guard
The wand has a Tip Guard installed at the factory only when a duckbill is installed. This Tip Guard
is not required when using sealing disk or dripless tip adapter. The purpose of this guard is to
prolong the life of the duckbill and to protect the operator in the event of a duckbill failure. Ensure
this guard is installed properly before operating equipment. See below.
