To avoid damage the batteries and shortening their work

ing life, do not use the machine once the

batteries are at the minimum level.

TANK EMPTYING

When the recovery tank is full, the ball in float ball filter (36) blocks off the inlet of suction hose to turn off the

vacuum system. At the same time, the noise of suction motor is increased suddenly to remind operator emptying the

recovery tank. The vacuum system is deactivation, and the floor is not dried.

CAUTION!

If the vacuum system is turned off accidentally (For example, when the float is activated because

of a

sudden machine movement).

CAUTION!

Always keep the battery in a full charged state can extend its lifetime.

CAUTION!

Please charge the battery as soon as possible if the battery level is low, otherwise the lifetime of

battery can be reduced. It is better to check the battery at least once a week.

CAUTION!

If no on-board charged is equipped, use a qualified external charger for battery charging.

15

ENGLISH INSTRUCTION FOR USE

WARNING!

Wet battery charging produces highly explosive hydrogen gas.

Charge the battery in well-ventilated areas and away from naked flames.

Do not smoke while charging the battery.

Do not reinstall the recovery tank until the battery charging cycle is over.

WARNING!

Pay careful attention when charging WET battery as there may be battery fluid leakages.

The battery fluid is corrosive. If comes in contact with skin or eyes, rinse thoroughly with water

and consult a physician.

The steps to charge the battery:

1. Open the recovery tank cap (24)

to check if it is empty, if not, empty the tank first.

2. Turn the power switch (45) to off position “o“.

3. For WET battery only:

-

Check the battery electrolyte level, if necessary, full fill it.

-

Let all the battery covers open.

- Clean the surface of the battery if necessary.

4. Select one of below charging mode base on the charger type.

Use an external charger for battery charging

5. The external charger output must be 24V DC, make sure use the suitable external charger.

6. Connect battery connector to the charger and then connect charger to the supply mains.

7. Disconnect the charger conn

ector to the machine after charging is completed.

Use on-bard charger for battery charging

8. Open the security cover of battery charger interface.

9. Connect the end of the battery charging connector with the mains with a charging cable. (Please note the mains

must be Voltage 100 – 240V and frequency 50-60 Hz.) If the red warning light on the on-board charger

continues lighting, it shows that the charger is charging the battery.

10. The Green LED (51) lighting indicates that the battery is full charged.

11. Charging completed, disconnect the charging cable from supply mains

and cover the security cover.

NOTE
For more on-board charger information (35), refer to relevant manual.

SQUEEGEE CLEANING

ball filter tight, and fix the filter sponge (I) onto the float filter support frame (E). Finally, connect it to the

sewage suction hose (M).

5. Inspect the integrity of the tank sealing strip.

NOTE

Tank sealing strip (G) makes to produce the vacuum inside the tank when suction motor works. The

tank must be sealed can effectively absorb the water from the ground to recovery tank.

6. Check whether the contact surface of sealing strip (G) is integrity and sealing is sufficient. If necessary, take the

sealing strip of the tank out of the groove (H) and replace it.
