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 flush out the system. If the circuit
is connected to the burner fuel supply, comply with the
burner fuel specification when filling 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, Teflon impregnated
grease (part # 33384) at all times. Any other grease will
be liquefied 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 fittings with clean cloth before greasing, to
avoid injecting dirt and grit. Replace and repair broken
grease fittings immediately. If a fitting will not take
grease, remove and clean thoroughly. Clean lubricant
passageway.
1. Lubricate asphalt pump bearings, 2 locations

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.
