MAIN BROOM MAINTENANCE
To Adjust the Main Broom Height...
1 Drive the machine to an area with a level fl oor and set the parking brake.
2 See Figure 13. Press the One-Touch™ Sweep Switch (Y) to lower the main broom. DO NOT move the machine.
3 Lightly press the Drive Pedal (37) to start the main broom and let it run in place for 1 minute. This allows the broom to polish a “strip” on the
fl oor. After 1 minute, raise the broom, release the parking brake and move the machine so that the polished strip is visible.
4 Inspect the polished strip on the fl oor. If the strip is less than 2 inches (5.08 cm) or more than 3 inches (7.62cm) wide, the broom needs to be
adjusted.
5 To adjust, press the Broom Select Switch (AA) twice, or until the Main Broom Indicator Light (Y1) is fl ashing. The LCD Display (C) will show
the broom position bar graph (C8) and main broom symbol (C9) . Press and hold or repeatedly press the Broom Height Raise Switch (Z) to
raise the main broom or Broom Height Lower Switch (BB) to lower the main broom (the position indicator will move up and down to represent
the broom position). After 10 seconds without adjustment the main broom will be set at this position and exit the adjustment menu.
Start with the position indicator at the top of the bar graph for a new broom. Adjust the position indicator down as the broom wears. Replace
the broom when the position indicator reaches the bottom of the bar graph.
6 Repeat steps 1-5 until the polished strip is 2-3 inches (5.08-7.62cm) wide.
The width of the polished strip should be the same at both ends of the broom. If the strip is tapered, move the machine to a different area and
repeat steps 1-5. If the polished strip is still tapered, contact your Nil
fi sk Dealer for service.
