changing blades

It is recommended that ALL the blades on the trowel 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.

Perform the following procedure when changing blades: Please note the blade orientation on the trowel arm before removing.

1.Lift the trowel up, placing blocks under the main guard ring to support it.

2.Remove the bolts and lock washers from all the towel arms, and then remove the blades as shown in Figure 52.
