Installation of New Main Brush (cont)
Remove the three screws and washers and the bristle strip retained by them. Install the new strip and assemble the retaining screws and washers. Be sure to install the "V" of each strip in the same relation to the core as its companion strips. (See Fig. 11, page 11)
CAUTION: The strips must be carefully centered on the core before they are firmly lockedintoposition. Rotatethebroom by hand through a full revolution to check for possible interference with the shaft carriers at each end. Failure to check this area could result in damage to the drive mechanism.
Continue to replace one strip at a time, checking end clearance on each end, until all strips have been re- placed with new fillers.
Readjust the broom to allow for the new bristle strips.
The main brush is preadjusted at the factory to insure even engagement with the floor across its full width. However, should the brush show signs of uneven wear, end to end, compensating adjustments may be made. Raise or lower either end as required by changing the length of the adjusting rod. (See fig. 12)
