6.Examine stabilizer ring for out of round or bends. If ring is damaged, replace ring. If ring is found to be correct with no damage, set aside.

Changing Blades

It is recommended that ALL the blades on the entire machine are changed at the same time. If only one or some of the blades are changed, the machine will not finish concrete consistently and the machine may wobble or bounce.

1.Place the machine on a flat, level surface. Adjust the blade pitch control to make the blades as flat as possible.

2.Note the blade orientation on the trowel arm. This is important for ride-on trowels as the two sets of blades counter-rotate. Lift the machine up, placing blocks under the main guard ring to support it.

3.Remove the bolts and lock washers (Figure 33) that secure the blade to the trowel arm, then remove the blade.
