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 (41).
Battery discharge during operation
5 ． 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 the 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
Figure 12

USER MANUAL
11
recovery tank cover (25), and press the power switch (41 and 42) to turn on
the main power and the vacuum motor.
Recovery tank emptying
1. Turn off the machine.
2. Raise the squeegee assembly (14).
3. Move the machine to a dedicated draining location.
4. Grasp the handle (2) and tilt the machine backward until the
guide wheel touches the floor.
5. Remove the drain hose from the clip, bend the top end of
draining hose (A, Figure 13), and then remove the drain
hose cap. Lower the hose to a low level or on the ground to
drain the 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
6. Complete Steps 1 to 4.
7. As shown in Figure 14, turn open the lid of Solution tank (A)
counter clockwise (direction C), to 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:
1. Remove the brush / pad holder.
2. Drain solution tank & rinse with clean water.
3. Drain recovery tank & rinse with clean water.
4. Complete the daily maintenance procedures. (see maintenance
section)
5. Remove and rinse squeegee assembly with damp towel.
6. Keep recovery tank lid unsealed from tank to allow fresh air to circulate freely
PERIODS OF INACTIVITY
If the machine is not to be used for more than 30 days, please treat it in the following way:
1. Complete the necessary procedure that should be followed after the machine is used.
2. Disconnect the connector (9) connecting the battery and the machine.
3. In order not to damage the batteries, the batteries should be charged once every 3 months.
USING FOR THE FIRST TIME
After the first 9 hours of use, please check components to ensure all connections (electrical &
mechanical) are tight & check for any damage that may have occurred during operation. Check for
water leakage.

SQUEEGEE BLADE CHECK AND REPLACEMENT
1. Following the methods related in the previous section clean the squeegee (Figure 15)
2. Check the edge (E, Figure 15) of the front squeegee blade and the edge (F) of the rear squeegee
blade (D). On the whole length, they should be level. Otherwise, adjust their heights through the
following procedure.
－ Loosen the clip (G) to let the rear squeegee blade (D) separate from the bracket (M) for the
adjustment of the position of the squeegee. After the adjustment, lock the clip once again.
－ Loosen the screw on the handle (I) to adjust the front squeegee blade (C); tighten the handle
screw after adjustment.
3 Check if the front squeegee blade (C) and the rear squeegee blade (D) is intact and if there are
broken edges and cracks. If damage is found, change them according in the following way. If the
front edge of the rear squeegee blade (J) has worn, it can be flipped upside down and re-installed
(the top edge is required to be intact). If the top edge is also worn, change it by following the
procedure below:
－ Loosen the clip (G) to let the pressure blade separate from the bracket (M), take off the clip
bar (K), and then change or turn the rear squeegee blade (D) upside down. Re-install the rear
squeegee blade in the reverse order of taking it off.
－ Loosen the handle screw (I) and take off the front clip bar (L), and then change the front
squeegee (C).
Re-install the front squeegee blade in the reverse order of taking it off.
After changing the squeegee blade, adjust the level of the front and rear squeegee blades in
the procedures as described above.
4. Connect the Vacuum hose (11) to the squeegee.
5. Install the squeegee and tighten the knobs.
6. If necessary, adjust the squeegee by turning the adjustment knob (20) (refer to the procedures
for adjusting the balance of the squeegee).
