(Refer to the steps for adjusting solution flow.
CAUTION !
In order to avoid damaging the floor, when the machine stays in one place without
moving, remove hands from switches & turn off the main power switch (38).
TANK EMPTYING
When recovery tank is full, a float shut-off device (36) will block the inlet connecting to the
vacuum motor. Through a sudden increase of noise from the vacuum motor, it can be considered
that the recovery tank is full and requires immediate draining.
CAUTION !
If the vacuum motor is suddenly turned off (due to sudden movement resulting in an
activation of the float), and if a resumption of operation is needed, please perform the
following steps: press the power switch (38 and 39) to turn off the power and the vacuum
motor, and open the recovery tank cover (25) to check if the float has returned to the water
surface. Close the recovery tank cover (25), and press the power switch (38 and 39) to turn
on the main power and the vacuum motor.
