2.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 A Blade

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 at one time, 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. 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.

2.Remove the bolts and lock washers on the trowel arm, and then remove the blade. (Access is easier if the steps are removed.)

3.Scrape all concrete and debris from the trowel arm.This is important to properly seat the new blade.

4.Install the new blade, maintaining the proper orientation for direction of rotation.

5.Affix the bolts and lock washers.

6.Torque to 9 ft. lbs.

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

Trowel Blade Removal

1.Remove the trowel blades from the trowel arm by removing the three hex head bolts (Figure 32) from the trowel arm. Set blades aside.
