If necessary, turn off the machine, and adjust the squeegee. (Refer to the steps for squeegee adjustment)3.
If necessary, turn off the machine, and adjust the solution flow with the ball valve handle. (Refer to the steps for adjusting solution flow.4.
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 (41).
Battery discharge during operation
It is only when the green warning light (38) is continuously lit that the power supply of the battery is sufficient for the normal operation of the5.
machine.
NOTE
When all the four green lights (38) turn on, it shows that the battery is fully charged. When only the last green light (38) is on, and
begins to flash, suggest charging the battery, as the machine will stop automatically after a few minutes. After the last green light (38)
turns off, and the red light (39 and 40) begins to flash, the machine will stop automatically after a few seconds. (Refer to the steps
related in the maintenance section).
CAUTION !
Do not use the machine when the power supply of the battery is insufficient, so as to avoid damaging the battery and shortening the
battery life.
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 (41 and 42) 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 (41 and 42) to turn on the main power and the vacuum motor.

water. Alternatively, place drain hose to a low position or on the ground to make the water
outlet face downward (B, Figure 13), and then twist open the drain cap to drain the wastewater
in the tank. After draining is completed, rinse the inside of recovery tank with clean water
CAUTION !
When draining the wastewater, the drain hose must be folded or lowered to a lower
position (Figure 13 A or B), and the cap removed for wastewater to drain. Do not allow the
opening of the drain hose to face upward, as it could get wastewater on the operator..
SOLUTION TANK EMPTYING
Complete Steps 1 to 4.6.
As shown in Figure 14, turn open the lid of Solution tank (A) counter clockwise (direction C), to7.
drain Solution tank completely. Use clean water to rinse the inside of Solution tank. When work
is completed, replace the solution tank lid (A) by twisting in a clockwise in direction (B).
AFTER EACH USE
When work is done and before leaving the machine, completes the following steps:
Remove the brush / pad holder.1.
Drain solution tank & rinse with clean water.2.
Drain recovery tank & rinse with clean water.3.
Complete the daily maintenance procedures. (see maintenance section)4.
Remove and rinse squeegee assembly with damp towel.5.
Keep recovery tank lid unsealed from tank to allow fresh air to circulate freely6.
PERIODS OF INACTIVITY
If the machine is not to be used for more than 30 days, please treat it in the following way:
Complete the necessary procedure that should be followed after the machine is used.1.
Disconnect the connector (9) connecting the battery and the machine.2.
In order not to damage the batteries, the batteries should be charged once every 3 months.3.
USING FOR THE FIRST TIME
