Be Aware of Signal Words
Signal words designate a degree or level of hazard seriousness.
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury. This signal word is limited to the
most extreme situations, typically for machine
components that, for functional purposes, cannot
be guarded.
WARNINGindicates a potentially hazardous situationwhich, if not avoided,could resultin death or
serious injury, and includes hazards that are exposed when guards are removed. It may also be
used to alert against unsafe practices.
CAUTION indicates a potentially hazardous situation which, if not avoided,may result in minor or
moderate injury. It may also be used to alert
against unsafe practices.

Transport Machinery Safely
Maximum transport speed for implement is 20
mph. Some rough terrains require a slower
speed.Sudden brakingcan cause atowed loadto
swerve and upset.
▲ Do not exceed 20 mph. Never travel at a
speed which does not allow adequate control
of steering and stopping. Reduce speed if
towed load is not equipped with brakes.
▲ Comply with state and local laws.
▲ Do not tow an implement that, when fully
loaded, weighs more than 1.5 times the weight
of towing vehicle.

▲ Do not fold or unfold the sprayer while the trac-
tor is moving.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the
skin, causing serious injury.
▲ Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
▲ Use a piece of paper or cardboard, NOT
BODY PARTS, to check for suspected leaks.
▲ Wear protective gloves and safety glasses or
goggles when working with hydraulic systems.
▲ If an accident occurs, see a doctor immedi-
ately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene may result.

▲ Store or dispose of unused chemicals as
specified by the chemical manufacturer.
▲ Before adding chemical to the tank, make
sure tank is at least half full. Do not pour concentrate into an empty tank.
▲ Never leave fill hose attached to the sprayer
after filling tank. Chemicals in tank can siphon
out of tank and contaminate freshwater
source.
▲ Always keep hand-wash tank filled with clean
water and have soap available in case of an
emergency. Immediately and thoroughly flush
any area of the body that is contaminated by
chemicals.
▲ Spray only with acceptable wind conditions.
Wind speed must be below 5 mph. Make sure
wind drift of chemicals will not affect any surrounding land, people or animals.
▲ Never wash out the sprayer tank within 100
feet of any freshwater source or in a car wash.
▲ Rinse out the tank. Spray rinse water on last
field sprayed.
▲ Do not touch sprayer components with mouth
or lips.
▲ If chemical is swallowed, carefully follow the
chemical manufacturer’s recommendations
and consult with a doctor.
▲ If persons are exposed to a chemical in a way
that could affect their health, consult a doctor
immediately with the chemical label or container in hand. Any delay could cause serious
illness or death.
▲ Dispose of empty chemical containers prop-
erly. By law rinsing of the used chemical container must be repeated three times. Puncture
the container to prevent future use. An alternative is to jet-rinse or pressure rinse the container.
▲ Wash hands and face before eating after
working with chemicals. Shower as soon as

Field Adjustments
Foam Marker
The foam marker should be set so that when a pass is
makein the field with the foammarker on, you shouldbe
able to clearly see the foam marker on the next pass. If
too much foam is being applied, you will have to fill up
the foam marker more often. The rate of foam coming
out of the foam marker can be adjusted with the foam
control valve, refer to Figure 7, page 14.
If youfind thatthe dropsof foamare not large enough to
see, a foam marker bell can be placed on the end of the
drop hose to make larger foamdrops. Referto the parts
manual on page 1-1 to purchase a foam marker bell.
Foam Marker Preparation
General Notes for Field Operation
1. Check to make sure the foam marker is securely attached to its mount, and the foam generator cylinders are securely fastened to the boom.
2. Check the volume of soap in the foamtank to make
surethere is enough soap tooperate the foammarker for the time you will be spraying.
3. Check the foammarkerclear hose that routes along
the boom to be sure her are no kinks in the hose.
4. Turn on the foammarker by turning the foammarker
switchto the left orrightandsee if the powerlighton
the foam marker lights up. If the light does not turn
on, the foam marker does not have power. Check
the wiring harness plug.
