6. SOLUTION STRAINER
The solution strainer is located in front of the left

solution flow to the ground, check the strainer for
debris. Drain the solution tank and clean the
solution strainer. To remove the strainer, turn the
bottom part of the strainer counterclockwise until
the bottom is separated. Clean out the debris
from the wire mesh and re-assemble. Make sure
the O-ring gasket is in place when re-assembled
