OPERATIONS OF CONTROLS AND GAUGES
HOPPER LIFT - (VARIABLE MACHINES ONLY)
The Hopper Lift Lever (AF) is located to the left of the steering wheel on the left side of the driver compartment. This lever, which is marked
“HOPPER”, raises and lowers the debris hopper to ease unloading.
WARNING
The hopper may drop unexpectedly and cause injury, always engage the safety arm before working under the hopper.
HOPPER SAFETY LOCK ARM (VARIABLE DUMP ONLY)
WARNING
When the hopper is raised the safety arm must be engaged before any work is done under the hopper
The Hopper Safety Lock Arm is located under the hopper assembly. After the work is complete, the safety arm must be disengaged.
HOPPER DUMP DOOR - (VARIABLE DUMP MACHINES ONLY)
The Hopper Dump Door Lever (AE) is located to the left of the steering wheel on the left of the driver compartment. This lever opens and closes the
hopper door. This lever is located below the Hopper Lift Door and is marked “DUMP DOOR”.
SOLUTION CONTROL
To apply solution to the scrubbing brushes, push the Solution Control Lever (X) forward until the desired setting is reached. The solution rate is
continuously variable from off to approximately 1-3/4 GPM at low and 3-1/2 GPM at high. To stop application of solution, pull back on the lever until
it stops at the “off” position. The solution warning light will illuminate when the solution tank is empty, marking the end of the scrubbing cycle.
NOTE
For best results, discontinue application of solution 10 feet
before stopping or making a 90° or 180° turn.
SWEEPING BROOM LIFT CONTROL
The Main Broom Lift Control (Y) is located to the left of the driver
seat. To lower the main broom, grasp the lever and pull back to
clear the locking notch. Move the lever forward to the fi rst or second
notch in the elongated slot. The fi rst notch, “SWEEP”, is for normal
sweeping (2 to 3 inch [5 to 8 cm.] broom pattern). The second
notch, “FLOAT”, is for heavy sweeping (4 to 5 inch [10 to 13 cm.]
broom pattern).
To raise the main broom, pull the lever back and slide into the locking
notch. You may operate the main broom in either the “SWEEP” or
“FLOAT” position. However, the “SWEEP” position should be used
for normal sweeping and will result in increased broom life. The
“FLOAT” position should be used only when sweeping extremely
uneven areas.
NOTE - (Variable Dump Machines Only)
A switch triggered by the hopper and dump door position
controls the sweeping functions, main broom, side broom,
dust control, and fi lter shaker. The hopper must be down and
the dump door open before these functions will work.
