11. Circulate clean water:
a. Fill the system hopper with clean water.
b. Turn the motor power switch (S) to ON to
begin circulating water. Increase flow and
pump for several cycles.
c. While pumping, open the fluid drain/purge
valve. Allow the water to flush out any
material to prevent material hardening in the
valve. Once the water appears clean, close
the fluid drain/purge valve.
d. Turn the motor power switch (S) to OFF.
12. Remove the applicator and clean/flush
separately.
a. Make sure all parts are free of residual
material.
b. Turn on air to make sure air lines are free
of obstructions.
13. Remove the remaining material with a hose
clean-out ball:
a. Place the hose outlet back in the waste
container.
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 hose 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. Repeat until all
sediment is removed from the hose.
Material left on the throat seal can dry out and
damage the seal. Always stop the pump at
the bottom of the stroke to avoid damage to
the throat seal.
e. If 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.

draining, release the pump lower inlet ball.
d. Disconnect the hose from the pump lower
outlet.
e. Starting at the pump, raise the hose bundle
above your head and slowly move towards
the applicator. As you move towards the
applicator, the remaining fluid in the hose will
drain from the applicator into the bucket.
f. Reattach the hopper to the pump.
