Operation
FOAM MARKER (Optional
Equipment)
The optional foam marker for this sprayer
automatically mixes foam concentrate
and water, and permits both the foam
density and delivery rate to be varied on-
the-go. Clear water is taken directly from
the rinse tank, and foam concentrate is
drawn from a separate tank.
•
Filling
Since the water used comes directly
from the rinse tank, ensure that the rinse
tank is full before starting spray
operation. This tank can be filled either
through the fill cap or the quick-fill
connector.
To fill the foam concentrate tank
(located on service platform), remove
the cap and add undiluted foam
concentrate. If spraying at temperatures
below 40
°
F, dilute concentrate 50/50
with water to ensure good flow
characteristics.
•
Foam Collector Height
Adjust foam collector drop hose until
collector is approximately one foot
above the ground, or to desired length.
•
Basic Operation
Before starting spray operation, test foam
output to ensure that foam density and
delivery rate are acceptable. (Additional
information on troubleshooting foam
output can be found in the
MAINTENANCE SECTION).
1. Press rocker switch LEFT or RIGHT
to activate system. Foam should
begin to drop from foam heads within
approximately. 1 to 3 minutes.
2. Observe foam appearance after
approximately 1 to 3 minutes of
operation. If output is unsatisfactory,
adjust
FOAM FREQUENCY and/or
FOAM MIXTURE controls. Allow
approximately 1 to 3 minutes after
each adjustment for new foam
setting to take effect.
3. On sprayers equipped with 90’/120’
booms, additional foam collector
heads are provided at a 60’ width.
The foam is redirected automatically
to these additional collector heads
when the outer wings are folded.
However, a delay of 1 to 3 minutes is
normal for foam to begin dropping
from these collector heads.
IMPORTANT: Boom electrical control
box must be in the <ON> position for
the 90’-60’ foam redirection to occur.
4. Move rocker switch to center position
to stop flow of foam.
