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.

all six sides of each of the four trowel arms. This is
important to properly seat the new blades.
4. Install the new blades, maintaining the proper blade
orientation for direction of rotation.
5. Reinstall the bolts and lock washers.
