smoothness.

2. If trowel bounces has excessive vibration or does not run

smoothly repeat alignment procedure.

NOTE

Before removing the blades,
please note the orientation of the
blade on the trowel arm.

2. Remove the three bolts and lock washers that secure the

blade to the trowel arm. Remove the blade.

3. Using a wire brush, scrape all concrete particles and foreign

debris from the trowel arm.

4. Install the new trowel blade onto the trowel arm. Make sure

blade is installed correctly, maintaining the proper orienta-
tion for direction of rotation.

Reinstall

the three bolts and lock washers that secure the

blade to the trowel arm. Tighten all three bolts securely.

6. Repeat steps 2-5 for all remaining blades.

Changing a Blade

Whiteman recommends that

all the blades be changed at the

same time

. The machine may wobble or bounce if only some of

the blades are changed at one time.

1. Place the machine on a flat, level surface. Adjust the blade

pitch control to make the blades as flat as possible. Note the
blade orientation on the trowel arm.
