Hydraulic Oil
When adding or changing the hydraulic oil, refer to
Table 7-2. Hydraulic Fluids Chart. Fluids that are
not equal to those listed could result in substandard
performance or failure of components.
Clean-out Solvent
Any commercially available cleaning solvent or release
agent can be used to ush out the system. If the circuit
is connected to the burner fuel supply, comply with the
burner fuel specication when lling the tank.
Do not use Terpene Hydrocarbon or
equivalent to clean out the spraybar. It destroys the
Viton seals.
Fluids And Lubricants
Asphalt Pump Lubrication
Use only Rosco high-temperature, Teon impregnated
grease (part # 33384) at all times. Any other grease will
be liqueed in the high operating temperature and will
run out of the bearings. With no lubrication, the bearings
will seize in a short time.
Use only a hand held grease gun for all greasing. Wipe
grease ttings with clean cloth before greasing, to
avoid injecting dirt and grit. Replace and repair broken
grease ttings immediately. If a tting will not take
grease, remove and clean thoroughly. Clean lubricant
passageway.
1. Lubricate asphalt pump bearings, 2 locations
(Figure 7-1) every 3 hours or twice daily.

2. Lubricate asphalt circuit valve stems, one location
on the 3-Way valve and the 2-Way valve every 3
hours or twice daily. Figure 7-2 shows the 3-Way
valve.
Lubricate the points described above
at the end of the day to prevent seizing or setting up
over night.
Grease For Other Components
Use an SAE multi-purpose high temperature grease
with extreme pressure (EP) performance or a SAE multi-
purpose lithium base grease.
