The following procedure should be followed to adjust trowel arms when

NOTE it becomes apparent that the trowel is finishing poorly or in need of routine maintenance.

Trowel Arm Adjustment Procedure

A level, clean area to test the trowel prior to and after is essential. Any unlevel spots in the floor or debris under the trowel blades will give an incorrect perception of adjustment. Ideally, a 13 cm x 13 cm (5 x 5 in.), 19 mm (3/4 in.) thick flat steel plate should be used for testing.

1.To determine which blades need adjustment, place the trowelinthetestarea(three-quarterinchthickplate)andlook for the following conditions:

■Pitch the blades as flat as possible and look at the adjustment bolts.They should all barely make contact with the lower wear plate on the spider. If you can see that one of them is not making contact, some adjustment will be necessary.

■Is the machine wearing out blades unevenly (i.e. one blade is completely worn out while the others look new)?

Figure 39 below illustrates a "worn spider bushings or bent trowel arms". Check to see that adjustment bolt is barely touching (.25 mm [.010 in.] max. clearance) lower wear plate. All alignment bolts should be spaced the same distance from the lower wear plate.

Figure 40 below illustrates the "correct alignment " for a spider plate (as shipped from the factory).
