Observe the amount of solution the machine is dispensing on the floor and adjust to the desired flow. To
increase the solution flow rate, rotate the solution control knob clockwise. To shut the solution off
completely just release the drive buttons. Solution stops when brushes stop.
Keep an eye on foam buildup in the recovery tank. If excess foam begins to develop, pour a
recommended foam control solution into the recovery tank. Foam is usually an indication of excessive
soap, so a better answer may be to use less chemical.
Always operate at lower speeds when scrubbing around walls and objects. You should also reduce the
speed to maintain control when turning.
If the squeegee starts to streak, raise and wipe the blades with a clean cloth. If the problem continues,
check the blades for wear or damage, and rotate if needed. You need to presweep before scrubbing if
you are using a disk machine. Alway's be sure to check the squeegee hose for clog's at the recovery tank
elbow.
Change or turn over pads when dirty. Rotate the scrub brushes every week.
Stay clear of objects protruding from the floor, such as sockets, grates, pipes, for they will damage the
pads and squeegee blades, or create dangerous situations.
During brief stops, you do not have to turn anything off. The brushes and solution will automatically stop
when the green control buttons are released.
Always keep an eye on your LCD window. They are there to help you scrub more efficiently, by letting
you know the status of that particular system at a glance. If the battery gauge is reading low, you must
stop immediately and recharge. Running the battery dead will result in damage to the battery.
When you run out of solution, raise the brushes, and continue to vacuum the remaining water until it is
consumed. The solution drain hose is also used to indicate the level of detergent remaining in the tank.
When you are ready to stop, pick up the brushes, turn off the solution switch, pick up the squeegee, and
drive the machine back to the charging area. Be sure to drain both tanks before storing machine for an
extended period of time.
