GROUND SPEED FOR ENVIROJET
APPLICATIONS
Normal pulse rate and injection depths require that the
Turf–Truckster speed be set at its lowest possible range
setting. To reduce the injection depth for certain product
applications, the pulse rate will need to be increased and
the speed of the Turf–Truckster may be adjusted (faster)
to accommodate the faster pulse rate.
Proper speed adjustment will allow for correct
application rate and/or an ideal injection pattern of 3 to
4 inches (7.6 cm to 10 cm). If the proper ground speed
has been adjusted, a small slit and hole will be visible on
the surface of the turf. If the ground speed is too fast, an
elongated slit will appear and the hole depth will be less
than normal.
Adjusting the height position of the injection manifold
(normally .37", 10mm) will effect the depth of penetration.
Always test the system on a small area before
proceeding to the major area that will be serviced.
STARTING CHEMICAL APPLICATION
NOTICE
S
If product is being injected, the mechanical agitation
system should be on continuously.
1. Release the deck safety lock located on the left side
of the engine frame.
2. Lower the injection deck assembly and place the
hydraulic control into the neutral/float position.
3. Check to make sure the bypass valve is in the
"Recirculation Mode" position.
4. Start the auxiliary engine and run in the recirculation
mode for three (3) minutes if tank had been emptied
previously. Bring engine to full throttle.
5. To start injecting, rotate the bypass valve clockwise
to the "Injection Mode" position.
6. To stop injecting (pulsing), rotate the bypass valve to
the "Recirculation Mode" position. Reduce the
auxiliary engine RPM or turn engine off if traveling
from one service point to another.
7. If your unit is equipped with a power brush, turn it on
(using the live hydraulics valve) after the deck is
lowered and shut it off before the deck is raised.
8. If the pulsing should stop during injection, open and
close the bypass valve several times to reactivate
the pulse. There may be some type of debris lodged
in the sequencer seating area. If pulsing will not
resume after operating bypass valve (several times),
the sequencer adjustment bolt must be turned fully
to the counterclockwise position and allow the
system to operate briefly to expel any particles.
Return the adjustment to the original preset position.

RE–LOADING CHEMICALS
1. If you are planning to apply another tank with the
same chemical, it
approximately 1–2 gallons in the tank to prevent air
from entering the system.
2. To re–load the chemical tank, follow the preceding
procedure.
3. Make sure the chemical mix in the tank is exactly the
same as the previous mix.
4. When returning to applying chemicals, BE SURE the
ground speed and spraying pressure are exactly the
same as the preceding application.
SHUTDOWN PROCEDURE
NOTICE
S
When the tank is empty the pulsing will stop. Shut the
auxiliary engine off IMMEDIATELY to prevent
damage to the high pressure pump.
1. If shutting the system down with a partially full tank,
rotate bypass valve to the "Recirculation mode"
position.
2. Reduce auxiliary engine RPM, run for a short period
of time to cool down and then shut auxiliary engine
off.
NOTICE
S
NEVER shutdown the auxiliary engine with the
bypass valve in the "Injection Mode" position.
3. Fully raise the injection deck.
4. Shut off the Turf–Truckster engine and engage the
parking brake.
5. Engage deck safety lock on the left side of the
auxiliary engine frame.
SYSTEM FLUSH PROCEDURE
NOTICE
S
After each use where products/chemicals have been
injected, the entire system must be thoroughly
flushed with clean pure water.
S
Thoroughly rinsing after using wettable powders is
especially important since powders will dry and cake
in valves and hoses.
1. BE SURE the drain valve is closed.
2. Fill the tank with clean pure water through the fill port.
3. Start the Turf–Truckster engine and engage the
PTO.
4. With the mechanical
functioning, open the drain valve to empty the tank.
NOTICE
S
DO NOT drain tank into storm sewer, waterway or
other area that could cause damage to the
environment.
