Operation
Preventing Spraybar Failure
It is very important to keep the spraybar cylinder rods
free of asphalt build-up. Build-up on these rods may be
pulled into the cylinder and cause premature failure of
the cylinders.
Some asphalt materials may build up faster than others.
Therefore, check the cylinder rods frequently. It may
be necessary to clean the cylinder rods several times a
day. The rods must be cleaned at the end of each day.
See Washdown, later in this section, for recommended
solvents.
Fire Hazard! Never spray cleaning
solvent or release agent on or near a heating
element that is hot or being heated or on or near
any open ame or source of ignition. Do not operate
Burner System during cleaning! Cleaning solvent and
release agent could ignite causing serious personal
injury.
When using spray down, consider the
environment and do not allow cleaning solvent to run
onto the ground.
DO NOT SMOKE around the machine.
Fuel, asphalt material and the fumes from both
can explode when exposed to ame or heat from
smoking or other sources.
4. Mark the link of the chain that gives the proper
height for a job so there is no need to recount the
chain links each day. If the bar is improperly set,
streaking or wind distortion of the spray fans may
occur.
