FUNCTIONS AND NOTES

FUNCTION
DP-SCRUB20 is suitable for ceramic tile flooring, marble flooring, epoxy flooring, PVC flooring, diamond flooring, terrazzo flooring, concrete flooring, and hard floor cleaning. It has an 18-inch brush or pad driver to clean the floor, and the dirty water will be sucked into a recovery tank by the squeegee. Cleaning is finished after passing over the floor one time. The best feature of this machine is quick dirt removal from the floor and it only requires one person.

ATTENTION

1. This machine is a high-efficiency, hard floor scrubber with clean and suction function, but no sweep function. To avoid any tangling and blockage, sweep the floor before operation.
2. This machine is suitable for smooth, hard floor cleaning. If you attempt to clean a tile floor with gaps or a rough marble floor, although this scrubber can remove dirt, it can not absorb the dirty water completely as it would on a smooth floor.
3. This machine is designed for smooth, hard floors. To avoid any potential risk, do not walk and operate on an inclined plane.
4. Store and park the machine on a horizontal surface. Inexperienced people are forbidden to operate the machine.
5. Do not start or store the machine in an area with flammables, explosives, and chemical medicine.
6. The operator is forbidden to wear slippers or be barefoot.
7. Do not put your hands or feet under the moving brush pad.
8. Keep the electrical control parts away from water and any other liquid, it is useful to wipe the machine with a wet cleaning cloth.
9. Maintenance and amendment should be done by professional personnel.

Battery-powered and equipped with an automatic walking device, The DP-SCRUB20 is a professional floor-cleaning machine with the following characteristics:

1. Simple operation All actions including accelerating, stopping, or retreating can be conducted by operating on the same handlebar. When this machine retreats to its limiting position, its emergency stop switch will drive the machine in the opposite direction after being pressed by the operator, to prevent the operator from being injured.
2. Power indication Power can be indicated by different colored LCDs so that the operator is informed of the workload.
3. Convenient maintenance The recovery tank is detachable, you can take it off the machine, which is convenient for cleaning. You can rinse the filter by screwing the floating frame. Or you can drain out the water in the solution tank separately, which is convenient for machine maintenance.
4. The dirty water tank cover is transparent, for easily checking tank levels. The transparent water level pipe clearly shows the water level. The suction motor is fixed under the dirty water tank for silent cleaning.
5. Pressurized function makes cleaning much easier, even for a floor with heavy dirt.
6. Convenient for maintenance Squeegee replacement is quick and convenient. Loosen the two fixed squeegee knobs in the suction squeegee, pull off the suction hose connection, then take off the suction part. Replace the back squeegee by loosening the fastener. Reverse the upper and lower to reuse the squee.

SPECIFICATIONS

BEFORE FIRST USE

New machines should be operated according to the following procedures during their first use. (The operation should be implemented under the instruction of the sales engineer assigned by the company or agent)

1. To avoid harmful interference, the machine should be removed from the package carefully and the accompanying documents and spare parts should be checked with great care.
2. Only after having a full understanding of the content of the operator’s manual, the operator can handle this machine. (A specific person should be assigned to operate this machine)
3. The sales engineer or distributor will introduce how to control the handlebar.
4. Align the battery and make sure that the batteries and output device are correctly connected. Never make a mistake on the polarity of the battery. The batteries can be connected with the power only after the connection of the batteries is confirmed to be right. (This operation can be carried out only after the on-spot inspection has been made by the sales engineer.)
5. Connect the squeegee to its frame, then screw down the fixed handle and connect the tube to the machine connection.
6. Take out the brush disk or needle bed and then choose a proper brush disk or cleaning pad to prepare for installation by the floor condition.
7. With the lock open, the function test is carried on to observe whether the power display and function keys are normal. Only after further tests show nothing wrong, the next operation can be implemented.
8. Pour water into the solution tank and then add the proper amount of cleaners; install the brush disk.
9. Loosen the brake pedal.
10. Turn on the power switch.
11. Lay down the squeegee and brush disk.
12. Start the suction motor and brush motor.
13. Pull the water valve switch upwards to regulate the water output.
14. The clean-out operation can be carried out by pushing forward the control handle as well as adjusting the walking rate.
15. After cleaning, the brush motor and water absorption motor should be turned off one after another.
16. Uplift the brush disk, squeegee it, and drain the dirty water out. The machine should be cleaned and maintained according to the requirements in the operator’s manual if a whole day’s work is finished.
17. Move the machine to the parking place, turn off the power, and push down on the brake pedal.

OPERATION AND MAINTENANCE

1. Before operating, big pieces and dust on the ground should be removed. The operation should never be carried out until no dirt, block, or wastepaper can be found on the ground, and all those procedures will help to increase the work efficiency and protect the machine.

2. Insert the activation key into the start switch and rotate it to “1” (Seen in figure 1) to check the battery capacity. Op-eration should never be carried out until the green light turns on (seen in figure2) to indicate the full capacity of the battery.
   Green light x4| Battery power 100%
   ---|---
   Green light x3| Battery power 80%
   Green light x2| Battery power 60%
   Green light x1| Battery power40%
   Red light flash| Battery needs to be charged

3. Fill the solution tank with clean water, add detergent according to the floor status. There are 2 ways to water filling (see Figure 3)

4. Lift the brush pedal to lower the brush disk down to the ground. (Seen in figure4)Lift the squeegee handle to lower the squeegee down to the ground. (Seen in figure5)

5. Operate the switches to control the brush and suction motor.

   • suction motor on only – use for water-sucking.
   • brush on only – clean a floor with heavy dirt
   • both switches on – dual cleaning.

6. Use the pressurized function when cleaning heavy dirt. Lifting the handle gives the brush more pressure on the floor. Regress to get back to normal. (See Figure 6)

7. Control the clean water flow rate by operating the water valve knob according to different floor situations. This makes for high-efficiency cleaning and no waste by properly consuming detergent. (see figure 7)

8. With the regulating handle of the squeegee, increase or decrease the angle between the squeegee and the floor. The suction of dirt would be efficient with a suitable included angle. (see figure8)

9. Regulating the pressure between the squeegee and the floor

   • screw the small casters up to keep them from touching the floor when the squeegee is working, then adjust the included angle between the squeegee and floor to have the best working status for the squeegee. (the included angle is 90° between the rubber blade and the floor).
   • screwing the casters down keeps them on the floor when the squeegee working. Keep adjusting the casters until the squeegee is working efficiently.
   • screw the casters up a bit, to give the squeegee the best working efficiency (see figure 8).

10. If there is still cumulation after one way cleaning on a rough floor, just lift up the squeegee and switch on the suction motor, repeat the sucking in that area.

    • Deep grooves may cause incomplete cleaning, please dispose separately.

11. Problems occurred while adjusting the water suction. During the operation, you should stop the machine and check it immediately if the suction motor sounds abnormal, or if the squeegee can not suck or absorb water at all.

    • When the water level rises to the highest point (the bobber can touch the cap), the sewage should be discharged.Method: Take the waste pipe out of the clip, open the cap of the tube, discharge sewage to the sewer and clean the recovery tank.
      (Seen in figure 9)

    • If the water level of the recovery tank is not too high and it’s not bubbling, the connection between the squeegee and the hose should be checked for clogs. In this case, the water sucker will recover normally after being cleaned.

    • If the water level of recovery tank is not so high but
      it is bubbling too much, that indicates that excessive cleansers have been added or the cleanser you used is a bubble-productive one. The water absorption motor recovers only after enough bubble-dispelling agents are put into the recovery tank.

    • Remove the upper cover (see in figure 10), start up the suction motor, and make sure that the suction intake is normal. If the suction is too weak, check the seal and whether the floater is jammed (Seen in Figure 10).

12. Method for replacing the brush disk

    • Installation of the brush pad: Put the brush pad under its cover (If the dial is used, the brush pad should be installed on the dial, then put the brush pad under its cover.) Lay down the brush pedal and align the brush head with the brush clip. Then press, the brush disk will be installed automatically with the running of the motor. And then you can carry out your operation as usual.
    • Removal of the brush pad: There are two ways to remove the brush pad: The first way is to step on the brush pedal after the work (Uplift the brush pad), then turn off the brush switch. At this time, the brush pad will be removed automatically after the motor stops running. The second way is to press, and then the brush pad should be removed auto-matically in the condition that the brush pedal is stepped on.
      Note: If the brush pad is in the process of being raised, the brush motor should not be started up arbitrarily; otherwise, the brush disk will be removed automatically.

13. Method for replacing the batteries

    • turn off all the switches, and lift off the dirty water tank (see figure11)
    • loosen the strap of the batteries, discharge the connecting cables, and replace the batteries separately.

14. Maintenance of the squeegee As a major component of the machine, the squeegee will be worn away due to friction between the glue bars and the ground during operation. In case it is not effective, the following procedures should be conducted:

    • Check whether there is anything in the rubber scraper; (Prepare a towel to wipe the dirty rubber blade at any time)
    • Check whether the joint of the squeegee and hose is clogged up by the small pieces. (Remove the connection of the hose or squeegee to clean the clog.)
    • Check whether the angle between the scraper and the ground is proper; if not, you can adjust the angle by regulating the hand wheel. (Seen in figure8)
    • Check the wearing condition of the scraper edge. If the wearing condition is so serious that the adjustment will not work, turn over the rubber blade and use another side of it. (see figure 12) If another side is also worn out, it has to be replaced by new rubber blade.

15. Daily upkeep when the operation is finished:

    • clean the machine surface with a wet and dry cloth, and open the water tank cover to check and make sure there is no damage to the inside seal.
    • pumping out the dirty water from the pollution tank, then adding more clean water to wash the inside again.
    • uplift the brush and the squeegee, and pack the machine in a dry, flat place without combustible gas, combustible liquid, chemicals, or fire.
    • if unused for some time, please disassemble the battery from the machine and clean the tanks. Cover the opening of the tank cover with a dust cloth.
    • For the battery, you should keep charging as per the instructions in the clause even though the battery is disassembled from the machine.

16. Ensure the clean water tank is clean. Cumulation may cause a blockage. Clean the filter weekly to ensure the water pipe expedites when in operation (see Figure 13)

MAINTENANCE AND CHARGE OF BATTERY

This machine is battery-powered and thus the quality of the battery will directly affect the function of the machine. Please use the battery recommended by our company or other high-quality power batteries. (Never use any automotive battery.) To adapt itself to the requirements of various working conditions, a battery of 12V×2/100AH can be used in this machine. Please choose the proper batteries according to your demands. Except for the difference in capacity, the batter-ies can be classified into two main categories: maintenance battery and maintenance-free battery according to their nature. As an open-type battery, a great deal of vapor bubbles will be produced when charging the maintenance battery. Therefore, the battery chamber cover should be taken off every time it is being charged. The liquid height of the electrolyte should be often checked. If it is lower than a specified height, distilled water should be added in time.

(No mineral water, tap water, or plain boiled water; never add any electrolyte arbitrarily). The maintenance battery is characterized by simple operation, moderate price, and high price, and can have a very good performance ratio if maintained in good condition.
While using the maintenance-free battery, you don’t have to add liquid to its sealed structure. Yet because of its precision, the operator should pay more attention to the details in daily use. In case any mistake has been made, it will cause great economic losses. Though it is unnecessary to take the cover off when charging the maintenance-free battery, the specified or configured charger must be in use. If the charger designed for the common maintenance battery is used for charging the maintenance-free battery, it could explode. The maintenance-free battery is characterized by strict structure, non- electrolyte leakage, adding liquid, longer life than maintenance battery, and high price. Furthermore, the operator should pay more attention to the details in its daily use. Any minor mistake will cause great losses. Therefore, it requires the operator to be better informed or educated in operation. Whether you choose the battery recommended by our company or one bought by yourself, you should instruct your employees to pay more attention to the following cautions:

1. The added distilled water shall not exceed the upper limit line. If the electrolyte is too full, it will overflow through the holes in the battery cover. With the characteristic of conducting electricity, the circuit self-discharge will be formed in case the electrolyte flows between the positive plate and the negative plate. In this situation, the electrolyte should be wiped off or washed with boiled water.
2. Resist rust: Besides checking whether it is installed firmly, pay more attention to the oxide and sulfate produced by the battery clip. After cleaning the rust, Vaseline may be applied to resist rust.
3. Cleaning: Keep the battery exterior clean. Always clean the dust and dirt on the battery cover, as well as the overflowed electrolyte. This will help to avoid self-discharging.
4. The liquid height of the electrolyte: the performance of the battery can be ensured only by remaining at the normal liquid height of the electrolyte.
5. In low temperature: when this machine enters the low-temperature zone, full discharging of the battery should be avoided. The charging rate at low temperatures will become slow.
6. Discharge: This machine uses a microcomputer to monitor the discharging of the battery. When the discharge is lower than the specified scale, the red light may turn on to alarm the operator. At that time, the battery should be charged as soon as possible.
7. If the machine is stored for over 30 days, its battery will be charged every 20-45 days; otherwise, the battery may be damaged.
8. Remember to charge the battery after finishing the work. Keeping the battery at full capacity will help to prolong the lifespan of the battery.
9. Please use the specified charger to charge the battery. The output voltage of the charger should be matched with the specified voltage of the battery, and the rated current should be matched with the capacity of the battery. Any mismatch between them may cause damage to the battery or charger.
10. Notice: If the charger designed for a maintenance-free battery is used for charging the maintenance battery, the maintenance battery lifespan will probably be shortened for long-term undercharge. If the charger designed for a maintenance battery is used for charging the maintenance-free battery, the maintenance-free battery could explode.

Battery Maintenance Tips

1. Take care of the electrolyte volume when using a maintenance battery. It’s necessary to avoid exposing the polarities to the air or it will cause injury to the electric volume and the battery lifetime.
2. Check electrolyte volume one time per week in summer, and one time per month in winter.
3. When left unused, continue to charge the battery one time per month or it will cause battery damage.
4. Try to charge the battery when the red light is on. Continuously charging the battery when it’s not dead will hurt the battery’s stability.
5. If the machine has the above problem, please correct the way it’s used. It could help to charge and discharge after using 3-5 times. If the problem is still there, please do a “deep discharge,” only turn on the brush or squeegee, and charge until the red light flickers. Usually, this would help after 3 cycles.
6. Hang up the dirty water tank(see Figure 14). It is best to keep the charger from lying directly on the ground. You can put it on a wall holder (see Figure 15), which is good for ventilating and keeping dry. Ensure the battery has good heat dissipation.
