Figure 6 EMERGENCY BRAKING If there is any emergency during machine operating, press the emergency switch (A, Figure 5), then all functions of machine will stop, there is no display on control panel (B, Figure 5)

BRUSH/PAD INSTALLATION AND UNINSTALLATION

NOTE Install suitable brush (A, Figure 6) or Pad (B and C, Figure 6) according to the type of floor to be cleaned. CAUTION Before installation or uninstallation of brush or pad, make sure all the switches on machine are in off position and lifting up the squeegee from the floor. The operator must be equipped with suitable personnel protection devices such as gloves to reduce the risk of accidents. Proceed as following: Battery Type Dip-Switches The charger's function is controlled by 4 dip-switches (2- pair) inside the back cover. The second 2 switches should never be touched unless the charger has been replaced and their position needs to be confirmed, set the battery voltage (24V) and maximum amperage (10A) and it should always be in the Off position. The first 2 switches are accessible through a plastic plug without opening the charger. These switches set the type of charge curve used for each type of battery. The curve type signifies the manner and magnitude in which current and voltage are applied to the battery during its distinct phases of the charge cycle.

1. Remove the plastic plug covering the DIP switch access hole (C).

2. Set the first 2 DIP switches (SW1) according to the table data below.

Figure 7). a) If there is gap between the ground and middle section of rear squeegee blade (B), adjust the knob (A) in counterclockwise direction (F) until all section of rear squeegee blade good contact with ground, the front blade touch the ground slightly. b) If there is gap between the ground and both end section of rear blade(C and D), adjust the knob (A) in clockwise direction (E) until all section of rear blade good contact with the ground, the front blade touch the ground slightly.

SOLUTION TANK FILLING

1. Open the water inlet cover (E, Figure 8).

2. Filling water or solution suitable for work performance through the water inlet with filter. The solution

temperature must not exceed +104F (+40°C).

3. Don’t overfill the tank, refer to water level indicator (G) for the water volume.

WARNING! Use only low-foam and non-flammable detergents intended for automatic scrubber applications. Drive motor inspection

1. Turn the key switch (A, Figure 9) to “ON”

2. Depress the accelerate pedal (C) slightly then loosen it to

check if the machine can be steered forward and stopped.

3. To ensure the security, confirm if the machine can be

stopped immediately by pressing the emergency button (B). Rotate the emergency button to reset it. CAUTION Climbing capacity of the machine must not exceed 10%. CAUTION The brake of drive motor is unstuck when the motor works normally, it locks when the motor stops working.
