A-12 / ENGLISH

SWEEPING

Follow the instructions in the preparing the machine for use section of the manual.
1 While seated on the machine, adjust the seat to a comfortable operating position using the adjustment controls (J).
2 Release the Parking Brake (F). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal
(G) to go forward or the rear of the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.
3 Push the Lower Hopper Switch (QQ) to make sure the hopper is seated properly. NOTE: The Hopper UP Indicator (MM) will be illuminated if
the hopper is not in the down position.
4 Move the Main Broom Lever (B) to the SWEEP (middle notch) position to lower and enable the main broom and dust control systems.
NOTE: The dump door opens automatically when the main broom (B) is lowered and closes when the broom is raised.
Use the FULL FLOAT (last notch forward) position only when sweeping extremely rough or uneven À oors. Use at other times will only
increase broom wear.
5 When sweeping À oors with puddles, push the Dust Control Switch (JJ) to turn OFF the dust control system before the machine enters a
puddle. Turn the dust control system back ON when the machine is back on completely dry À oor. NOTE: This is done to prevent the Hopper
Dust Control Filter (12) from getting wet.
When sweeping wet À oors, keep the Dust Control Switch (JJ) OFF at all times.
6 The Side Broom (9) is automatically enabled when the main broom is lowered and starts spinning when the Drive Pedal (G) is activated. The
Side Broom (9) can be turned off and back on at any time by pushing the Side Broom Switch (HH).
The side broom sweeping pattern is adjusted by turning the Side Broom Height Adjustment Knob (10).
7 Drive the machine straight forward at a quick walking speed. Drive the machine slower when sweeping large amounts of dust or debris or
when safe operation dictates slower speeds. Overlap passes 6 inches (15 cm).
8 If dust comes out of the broom housing while sweeping, the Dust Control Filter (12) may be clogged. Push the Shaker Switch (LL) to clean
the dust control ¿ lter. The dust control system (JJ) will automatically turn OFF while the shaker is running and turn ON after the shaker turns
OFF (the shaker runs for 15 seconds).
9 Check behind the machine occasionally to make sure that the machine is picking up debris. Dirt left behind in the path of the machine usually
indicates that the machine is moving too fast, the broom needs to be adjusted, or the hopper is full.
NOTE: If the machine does not move for 40 seconds, the engine will automatically return to idle. The sweep system will only activate with the
engine RPM at high. To begin sweeping again press the Engine Speed Switch (GG) to return engine RPM to high.

EMPTYING THE HOPPER

WARNING!
Make sure the Hopper Safety Support (5) is in place whenever attempting to do any maintenance work under or near the raised
hopper. The Hopper Safety Support (5) holds the hopper in the raised position to allow work to be performed under the hopper.
NEVER rely on the machine's hydraulic components to safely support the hopper.
NOTE: The MINIMUM ceiling height dumping clearance required for raising the hopper is 102" (259.08 cm)
1 Put the Main Broom Lever (B) in the UP / OFF position. NOTE: The Shaker will automatically run for about 15 seconds after the main broom
is raised.
2 If you do not raise the main broom, push the Shaker Switch (LL) to remove excess dirt from the dust control ¿ lter.
3 Drive the machine close to a large trash receptacle and hold the Raise Hopper Switch (RR) until the hopper is all the way up. NOTE: The
dump door automatically closes when switch (RR) is pushed. You regain control of the dump door as soon as the hopper begins to raise so
you can dump at any height if necessary.
4 Move the machine forward until the hopper is over the receptacle and set the Parking Brake (F). Press the Open Dump Door Switch (NN) to
open the dump door and empty the hopper. NOTE: If not dumping into a trash receptacle, low dumping is recommended to help eliminate
airborne dust.
5 Put the Hopper Safety Support (5) in place by pulling back on the Hopper Safety Support Pull Rod (I), then lower the hopper slightly to
secure.
6 Check the hopper door and the front edge seal. Use a broom, if necessary, to remove litter from these areas. The hopper door must seal
tightly against the broom housing bulb gasket for proper operation.
7 Return to the operator's compartment. Release the parking brake. Move the machine back until the hopper will clear the receptacle. Raise
the hopper slightly and push forward on the Hopper Safety Support Handle (I) until the Hopper Safety Support (5) disengages, then lower the
hopper. NOTE: The brooms will not turn on if the hopper is not completely down. The indicator light (MM) on the control panel should turn
OFF indicating that the machine is ready for use.
