18. Tank Supply Valves (Figure 4-2). Located in front of
the control panel, these valves control the draw from
the tanks and supply the sprayer system.
19. Tank Return Valves (Figure 4-2). Located in front of
the control panel, these valves control the return flow
to the tanks from the sprayer system.
20. Hopper Diffuser Control (Figure 4-2). Located on
the control panel, the hopper diffuser control allows
the user to equalize the the material spread from
side to side.
21. Spreader Speed Control (Figure 4-2). Located
on the control panel, the spreader speed control,
controls the speed of the spreader motor and should
be adjusted to control the width of the spread
pattern.
22. Granular Drop Rate Cam (Figure 4-2). Located in
front of the machine below the hopper, is used to
control the drop rate of the granular product from the
hopper.
23. Granular Hopper (Figure 4-2). Located at the front
of the machine, the granular hopper has a 220# (100
kg) capacity.
24. Spreader Control Switch (Figure 4-2). Located
on the control panel, the spreader control switch
activates / deactivates the spreader motor. Stepping
off the operator platform will also shut off the
spreader motor.
25. Digital Display (Figure 4-1). Located on the control
panel, the display allows the operator to see various
functions of the machine including ground speed,
hours, distance, and many other important metrics
for the machine. See Section 4.1
26. Hopper Deflector Control (Figure 4-2). Located
on the control panel, the hopper deflector control
activates / deactivates the side deflector for the
spreader system.
27. Hopper Gate Control (Figure 4-2). Located on the
control panel, the hopper gate control opens / closes
the hopper gate.
28. Sprayer Control Switch (Figure 4-2). Located on
the control panel, the sprayer control switch activates
/ deactivates the pump for sprayer system.
29. Foamer Control Switch (Figure 4-2). (optional
accessory). Located on the control panel, the
foamer control switch activates / deactivates the
foamer system.
30. Left / Center / Right Spray Booms (Figure 4-2).
Located on the front of the machine, the spray boom
is divided into 3 sections (left, right, and center)
and are controlled by each boom's Sprayer Nozzle
Control lever.
31. Nozzles (Figure 4-2). Located on the spray boom,
the nozzles produce a fine mist for proper application
of product.
32. Spray Wand Supply Valve (Figure 4-2). Located by
the hose reel, the valve controls the draw from the
tanks and supplies the hose reel with chemicals.
33. Spray Tank (Figure 4-2). Located on both sides of
the machine, are used to mix and supply chemicals
to the sprayer system.
34. Forward Speed Control (Figure 4-2). Located
on the sides of the control panel, used to set the
maximum forward speed needed when applying
product. Speed will vary depending on application
rate of the product being applied.
4.3 SAFETY INTERLOCK SYSTEM
The machine is equipped with a safety interlock system
intended to protect the operator and others from injury.
This is accomplished by preventing the engine from
starting unless the sprayer/spreader is disengaged, the
parking brake is engaged, the steering control levers are
in the neutral position and the operator is in the operator
position. The interlock system shuts off the engine if the
operator leaves the operator platform with the steering
control levers not in the neutral position and/or the
sprayer/spreader is engaged and the parking brake not
engaged.
4.4 TESTING THE SAFETY INTERLOCK
SYSTEM
The safety interlock system should be tested each time
before using the machine. If the safety interlock system
does not operate as described below, contact your local
Authorized Scag Power Equipment Dealer immediately to
have the safety interlock system repaired.
-NOTE-
The machine will not start with the operator off
of the platform. For all test procedures listed
below, the engine must be started with the
operator standing on the platform unless specified
otherwise.
