Always flush the pump, hose, and applicator with
water before loading material.
Always follow the material manufacturer’s instructions
for the material being sprayed. Material must be
thoroughly mixed to a smooth consistency before
loading it in the hopper.

Mixing:
• Pay close attention to the work life of the material
being used.
• Only mix the material kits as needed. Do not let
mixed material sit longer than necessary.
• Scrape material down the sides of the hopper as
the hopper material level lowers. Do not let older
material cure on the walls.
• Occasionally, do not refill the hopper until it is
almost empty. This ensures all material in hopper
is used while fresh.

NOTICE
To prevent material curing in system, never load
material into a dry system. Loading material into
a dry system will cause the material to stick to
internal components and cure causing damage
and requiring replacement of those parts.
The applicator nozzle or tip must be removed during
priming. Always push out any remaining water into a
waste container before circulating material. Always
circulate clean material back into the hopper for a few
minutes before beginning to spray.

7. Set the hydraulic switch (BB) to ON, and the
pump control switch (AA) to ON.
8. Increase pressure by turning the hydraulic
pressure control (S) clockwise until a steady
stream of mixed material flows from the hose
outlet.
9. To stop dispensing, switch the pump control
switch (AA) to OFF.
10. Remove the tip from the applicator and install
onto the hose outlet. Switch the pump control
switch (AA) to ON and pump until material flows
from the applicator.
11. Turn the pump control switch (AA) OFF to stop
dispensing.
12. Install a tip onto applicator (see Applicator
manual 3A3244). The system is now primed and
ready to spray.
