Cleaning The Reduction Chamber

WARNING: 

The impeller’s shredder 

blade and chipper blades are sharp. 

Wear leather work gloves to protect 

your hands when cleaning out the 

reduction chamber.

If the reduction chamber becomes clogged with 

debris, the shredder screen can be pivoted upward 

so that you can clean the surrounding area. To do so, 

proceed as follows:
1. 

Stop engine, make certain the chipper 

shredder has come to a complete stop, and 

disconnect the FLEX™ Power Base from the 

attachment.

WARNING: 

The muffler and 

surrounding area will be hot if the 

engine has been running. Use caution 

and protect your hands if working 

near the muffler. 

2. 

If attached, remove debris bag. Remove the 

two wing knobs on either side of the chute 

deflector and pivot the chute deflector 

upward. See Figure 5-1.
