O
PERATION
When the 4 wheel drive option is installed on a machine, there are no switches required to activate it, the
machine is always in 4 wheel drive mode as long as it is in Low Range (Field). The 4 wheel drive mode will not
work in High Range (Road) as this speed is intended for High speed transport only. If traction is lost at any
time with either the front or rear tires, operator should depress the switch located on the floor near the operators
right foot. This makes a temporary “posi-traction” link between the front and the rear. When the difficult spot is
cleared, release the switch and continue on. It is not intended for the “posi-traction” switch to be depressed for
long periods of time, or when the machine is making a sharp turn.
Electronic Digital Display —————
1. The Electronic Digital Display has 2 different screens that show critical values and the status of different
systems on the 33 Series Sweeper.
a. The first screen will display the following: (This is the default screen upon start-up)
i. Engine Oil Pressure (psi)
ii. Coolant Temperature (deg F)
iii. Battery Voltage (V)
iv. Engine Hours (hrs)
b. The second screen will display the following: (This screen is accessed by pushing [2 times]
either one of the 2 center Soft Keys.)
i. Vehicle Speed (mph)
ii. Engine RPM (rpm)
2. The Digital Display also has a warning screen to alert the operator of a potentially harmful situation.
This warning screen display is:
a. Do Not Sweep in High Gear
i. This screen will flash once every 5 seconds when in high gear.
3. Other functions of the Digital Display unit are as follows:
a. The Left Soft Key (push 2 times) allows you to adjust the brightness and contrast by following the
+ or – symbols above the Soft Keys.
i. When finished with the adjustment this screen will revert back to the Home Screen.
b. The Right Soft Key (push 2 times) brings up the Main Menu.
i. This screen is primarily for programming and requires the use of a PIN number to make
any changes in the program. Flory Industries retains possession of all programming
information.
ii. Press the Left Soft Key to EXIT this screen and return to the Home Screen.
Blower —————
The blower air stream (ON-OFF) is controlled with a “damper” that is hydraulically actuated by the
electrical “rocker switch” switch located on the top of the Speed Control Lever. The volume of air may be varied
from full “ON” to full “OFF” by the use of this control. Press on the right side of the switch to turn the blower ON,
and press on the left side of the switch to turn the blower OFF.
The blower spouts may be adjusted vertically to accommodate different field conditions, such as blowing
up hill, down hill, or when trees are planted on borders. The rear spout is adjusted with a hydraulic cylinder, and
the front spout is linked to the rear spout with a chain, so that they will operate together. The electrical switch for
the hydraulic cylinder valve is located on the control console. Press the switch up to raise the spouts, and press the
switch down to lower the spouts.
The deflector vanes in either spout may be adjusted both vertically and horizontally for maximum air
control.
It is not necessary to run the engine at full RPM if satisfactory blowing results can be obtained at a lower
engine speed. Lower engine RPM will result in less dust being generated by the blowing process.
