learn how to drain recovery and solution tanks)

DRAINING THE SOLUTION (CLEAN) TANK

: The brush motors are circuit breaker
protected to protect them from damage. If a
breaker trips, it can’t be reset immediately. You
must first determine what caused the breaker to
trip, and allow the motor to cool down before you
can reset the breaker. The breakers are located on
the back panel of the control housing.

: Anytime scrubbing operation is completed,
the solution tank should be drained and cleaned.
1. Pull down on the clear tube (back left of the
machine) to remove it from the hose barb.
This will allow the solution to flow freely into
a bucket or floor drain.
2. Rinse the solution tank with clean water after
every use. This will help prevent chemical
buildup and clogging of the solution lines.
3. With clean water in solution tank, turn
machine power on, solution switch “on” and
pull the operating triggers. This will allow the
clean water to flush through and clean the
solution plumbing.
4. Once tank is rinsed, flushed and drained,
reconnect the clear tube to the hose barb. Be
sure the tube is pushed all the way up on the
hose barb.
