Introductory comment

• SENTRY 141M is a floor scrubbing machine that, using the mechanical action of the rotating brush and the chemical action of a water/detergent solution, can clean any type of flooring. As it advances, it also collects any removed dirt as well as the detergent solution not absorbed by the floor.
• The machine must only be used for this purpose. Even the best machines will only work well if used correctly and kept in good working order. We therefore recommend you read this instruction booklet carefully, and consult it whenever difficulties arise while using the machine. If necessary, remember that our customer assistance service (organized in collaboration with our dealers) is always available for advice or direct intervention.

Intended use

• The floor scrubbing machine is designed for the professional cleaning of surfaces and floors in industrial, commercial, and public environments only. It is only suitable for use in closed (or at least covered) places.
• The machine is not suitable for use in the rain, or underwater jets. IT IS FORBIDDEN to use the machine for picking up dangerous dusts or inflammable liquids in places with an explosive atmosphere. In addition, it is not suitable as a means of transport for people or objects.

   • ATTENTION: If one of the three LEDs flashes refer to the battery charger manual supplied with the machine
   • ATTENTION: The machine is equipped with an automatic system that disconnects the power supply from the electrical system while the batteries are being recharged
   • ATTENTION: In order not to cause permanent damage to the batteries, it is essential to avoid their complete discharge: arrange the recharge within a few minutes of switching on of the “discharged batteries” blinking light.
   • ATTENTION: Never leave the batteries completely flat, even if the machine is not being used.
   • ATTENTION: For the daily recharging of the batteries, you must fully respect the indications provided by the manufacturer or retailer. all installation and maintenance operations must be carried out by specialized personnel.
   • ATTENTION: Do not move the machine when the battery charger power supply cable is connected to the battery charger.
   • ATTENTION: Danger of gas exhalation and leakage of corrosive liquids.
   • ATTENTION: Danger of fire: Keep naked flames at a safe distance.

If the charger is not incorporated into the machine, carefully read the use and maintenance manual of the charger being used to recharge the batteries.

BATTERY INDICATOR
The battery indicator is digital, with 4 fixed positions and a flashing one. The numbers that appear on the display show the approximate charge level.

• 4 = maximum charge
• 3 = ¾ charge
• 2 = 2/4 charge
• 1 = 1/4 charge
• 0 = discharged batteries (flashing)
  • ATTENTION: A few seconds after the appearance of the flashing “0”, the brush motor switches off automatically. With the remaining charge it is still possible, however, to complete the drying process before recharging

INSTRUMENT PANEL COMPONENTS
The instrument panel components are identified as follows:

1. Main switch (1).
2. Suction switch (2).
3. Solenoid valve switch (3).
4. Digital battery level indicator (4).

FIXING THE HANDLEBARS
For packaging purposes the handlebars are supplied folded; they must now be put in the working position. Proceed as follows:

1. raise the handlebars by pulling the lever – indicated by the arrow – upwards.
2. place the machine in the working position.
3. attach the recovery tank to the handlebars tube by means of the two hooks.

TROUBLESHOOTING

1. ELECTRICAL SYSTEM SAFETY
   The machine is fitted with self-restoring safety fuses located in the electric system (beneath the solution tank) that interrupt the power supply to the brush and suction motors when the machine exceeds the predetermined load. To restore the power supply to the motor, switch off the machine and wait for the fuses to cool down (about 40 seconds). If the switch disconnects the current again, contact the FIMAP technical assistance center.

2. INSUFFICIENT WATER ON THE BRUSHES

3. Verify that the solution tank filter is clean.

4. Verify that the solenoid valve switch is on.

5. Verify that the quick connection is correctly inserted.

6. Check the cock regulation screw on the water outlet.

7. THE MACHINE DOES NOT CLEAN WELL

8. Check the state of wear and tear of the brushes and, if necessary, replace them. The brushes should be changed when the bristles are about 15mm long.

9. THE SQUEEGEE DOES NOT DRY PERFECTLY

10. Verify that the squeegee rubbers are clean.

11. Verify that the suction tubes are correctly inserted in their housing on the squeegee.

12. Verify that the distributor is clean.

13. Replace the rubbers, if worn

14. EXCESSIVE FOAM PRODUCTION

    • Check that a low foam detergent has been used. If necessary, add a small quantity of anti-foam liquid to the recovery tank.
    • Remember that, when the floor is not very dirty, more foam is generated. In this case the detergent solution should be more diluted.

CHOOSING AND USING THE BRUSHES

POLYPROPYLENE BRUSH (PPL)
Used on all types of floors. Good resistance to wear and tear, and hot water (no greater than 60°C.). PPL is non-hygroscopic and therefore retains its characteristics even when working in wet conditions.

PAD HOLDER
The pad holder is recommended for cleaning shiny surfaces.

There are two types of pad holders of the CENTRE LOCK type, equipped with a snap-type central locking system in plastic that allows the abrasive floor pads to be perfectly centred and held without any risk of them becoming detached:

1. fitted with a series of anchor points that allow the abrasive floor pad to be held and dragged while working
2. fitted with a series of groups of bristles that allow the abrasive floor pad to be held and dragged while working
