A-16 / ENGLISH

BROOM HEIGHT ADJUSTMENT

The working height of the broom is adjustable to compensate for bristle wear. Before adjusting the broom, always check the length of the broom bristles. Replace the
broom if the bristle length is 4.4 cm or less.
To Adjust the Broom Height...
1 Drive the machine to an area with a level, dry fl oor and apply the Parking Brake (50).
2 With the engine running and the Brushes / Broom On-Off Lever (31) ON, put the Broom Raise-Lower Lever (35) in the SWEEP position (middle notch). Do not
move the machine. Let the broom run for 1 minute. This allows the broom to polish a strip on the fl oor.
3 After 1 minute, raise the broom and release the Parking Brake. Move the machine out of the way, so that the polished strip is visible.
4 The width of the strip should be 3.8 cm.
5 If the strip is too narrow (or too wide), open the lower access door on the left side of the machine, loosen the Locknut (C) and adjust the Turnbuckle (D). The
Turnbuckle controls the working height of the sweeping broom. Lower the broom if the strip is too narrow. Raise the broom if the strip is too wide. Then tighten
the Locknut.
