Maintenance
Solution Strainer
The solution strainer is located in front of the left front
wheel. The solution strainer protects the solenoid valve
from debris. If there is little or no 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 counter-
clockwise 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
Brush Motor
Do not use a pressure washer to clean around the
brush motors. Use tap pressure only.
