Prime with Water
To prevent material curing in the system, never load mate-
rial 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.
1. Fill the hopper with clean water.
NOTE: Some materials require a slicking agent to be
run through the hose. Consult the material manufacturer
for recommendation.
2. Turn the flow adjustment knob (H) counterclockwise
until it stops.
3. Place the applicator into a waste container.
4. Turn the motor power switch (S) to ON.
5. Turn the flow adjustment knob (H) clockwise slowly
to increase pressure, until water is purged out.
To prevent damage to pump seals caused by cavitation,
run the pump slowly until the system is primed.

6. Run the clean-out ball(s) to coat the inside of the
hoses.
a. Remove the applicator from the end of the
hose.
b. Remove the hose inlet from the pump outlet and
place a hose clean-out ball within the hose inlet.
The ball must be wetted down before inserting.
If using a 1 in. whip hose, begin with the
smallest clean-out ball.
c. Reattach the hose to the pump outlet and turn
the motor power switch (S) to ON to resume
flushing the hose.
d. The clean-out ball will be pushed out of the
hose after several minutes. Once the ball is
pushed through the hose, turn the motor power
switch (S) to OFF.
e. Is using a 1 in. whip hose, remove the hose and
transition fitting and repeat the process using
the large clean-out ball on the remaining hoses.
Once the ball is pushed out, pump out the
remaining water in the hopper, then reattach the
transition fitting and whip hose.
7. Remove the hose inlet from the pump outlet and
walk the water out of the hoses.
a. Starting at the pump, raise the hose bundle
above your head and slowly move towards the
applicator end. As you move towards the
applicator end, the remaining water will drain
from the hoses.
8. Detach the hopper from the pump (see Hopper
Removal, pg. 22) and properly dispose of any
remaining water according to local and state
regulations.
9. Use a screwdriver to lift the pump lower inlet ball
and drain the remaining water from the pump lower.
Once the pump stops draining, release the lower
inlet ball.
10. Reattach the hopper to the pump.
11. The system is ready to prime with material.
