MAINTENANCE

The solution system should be flushed every day to prevent a build-up of soap residue in the solution valve. To flush the
system...
1 Park the machine near a designated "DISPOSAL SITE" and drain the solution tank.
2 Put clean, warm water into the solution tank and let it drain through the drain hose.
3 When the tank is empty, re-cap the drain hose and put about 2 inches (5 cm) of clean, warm water in the tank.
4 Put the machine controls in the following positions:
• Key Switch (11) - ON
• Solution Switch (20) - ON
• Brush Drive (18) - Lowered
• Twist Grips (2) - Forward slightly
• Solution Flow Control Lever (1) - Pulled Back
5 Let all of the clean water flow from the tank. This will flush dirt and soap residue from the electric solenoid valve and
the flow control valve.
