Intended use

In short The Scrubmaster B120 R is meant for wet cleaning of hard indoor floors in commercial settings. Only people who know the work and have been instructed about the dangers may use, maintain or repair it, and unauthorised modifications void the declaration of conformity.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​​​⁠​​​‌​⁠​​⁠⁠​​‌⁠⁠​‌‌‌‌‍⁠​‍⁠‌⁠⁠‍‌‌⁠

Scrubmaster B120 R is a scrubber-drier for the wet cleaning of hard indoor floor surfaces. This machine is intended for commercial use, e.g. in shopping centres, swimming pools, shops, airports, schools and hotels. Any use extending beyond this is not intended use. The manufacturer is not liable for any damage resulting from this and the user alone bears the risk. Intended use also includes compliance with the operating, maintenance and servicing conditions specified by the manufacturer.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​​​⁠​​​‌​⁠​​⁠⁠​​‌⁠⁠​‌‌‌‌‍⁠​‍⁠‌⁠⁠‍‌‌⁠

The Scrubmaster B120 R may be used, maintained and repaired only by persons who are familiar with this work and instructed about the dangers.

Operation

2.3 General principle of operation

In short This section explains how the Scrubmaster B120 R cleans: solution goes from the solution tank to the rotating brushes and the squeegee carries used water to the waste water tank. It also covers the 120 litre solution tank, the low-water warning, and how the brush unit is lowered and decoupled.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍​‍​​​‌​⁠​​⁠‍​‍‍​‍​‍‍​​​​‍‌​‍⁠​​⁠‌‍

Scrubmaster B120 R is a ride-on scrubber-drier for wet cleaning hard floor surfaces.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍​‍​​​‌​⁠​​⁠‍​‍‍​‍​‍‍​​​​‍‌​‍⁠​​⁠‌‍

In cleaning mode, the cleaning solution is supplied from the solution tank to the rotating brushes in the brush unit. When the machine is moving forwards, the used waste water is absorbed by the squeegee and conveyed into the waste water tank.

Rear three-quarter view of the Scrubmaster B120 R ride-on scrubber-drier with its operator seat and steering wheel, with callouts 4, 5, 6, 26, 7 and 8 pointing from the top of the machine down to the brush unit area at the front
Fig. 9:

2.3.1 Solution tank

The solution tank Fig. 9-6 is filled via the filling opening Fig. 4-20. The solution tank has a capacity of 120 litres. The level can be determined via a transparent hose Fig. 10-30. If there are only 10 litres of fresh water left in the tank, the ball cock symbol flashes in the display panel and a warning sound (approx. 30 seconds) requests refilling.

2.3.2 Brush unit

The brushes in the brush unit Fig. 9-8 are driven by two electric motors. The brush unit is lowered with the brush unit button Fig. 5-36. When actuating the accelerator pedal, the brush motors and the water supply are switched on. The floor is cleaned by the rotating brushes and the supply of cleaning solution.

For maintenance purposes, the brushes in the rotating brush unit can be decoupled via the foot lever brush decoupler Fig. 8-7.

Operation

2.3.3 Squeegee

In short The squeegee is lowered and switched on with the squeegee button, and it removes waste water from the floor. For narrow sections it can be taken off and hooked into the waste water tank cover.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍​⁠​​​‌​⁠​​​‍​‍‍​‍⁠‌‌​⁠‌‌‌​‍​‍⁠‍‌‍‍

The movable, hinged squeegee Fig. 9-26 is lowered and switched on with the squeegee button Fig. 5-37. The squeegee withdraws the waste water from the floor using a sealing strip. The suction turbine vacuums the waste water from the floor. If the machine passes through narrow sections, e.g. checkout areas, the squeegee can be removed by loosening the star-shaped handle and hooked into the cover Fig. 10-A of the waste water tank.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍​⁠​​​‌​⁠​​​‍​‍‍​‍⁠‌‌​⁠‌‌‌​‍​‍⁠‍‌‍‍

3.4.6 Useful cleaning tips

In short This section gives tips for wet cleaning. Sweep first, and for very dirty floors or wax removal scrub twice, letting the detergent act for about 5 to 10 minutes between passes.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍⁠​​​​‌​⁠​​⁠​‌​‍⁠‍‌‍‍⁠‍‌‍‌⁠​‍​⁠⁠‍⁠‍

Sweep the floor before carrying out wet cleaning. This not only enhances the cleaning effect but also reduces wear of the machine's working tools.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍⁠​​​​‌​⁠​​⁠​‌​‍⁠‍‌‍‍⁠‍‌‍‌⁠​‍​⁠⁠‍⁠‍

If the floors are really dirty or wax needs to be removed, treat the floor twice. In the first step, scrub the floor with a detergent suitable for the degree of soiling; the squeegee remains raised for this.

Leave the detergent for approx. 5 to 10 minutes; subsequently scrub the floor again and work with a lowered squeegee.

Note
  • Only use detergents suitable for automatic machines (foam retarded). We recommend use of our detergents and care agents specifically developed for the machine. These products meet the requirements of the German Detergent and Cleaning Agent Act (WRMG).
  • Observe correct dosing of the detergent. Correct dosing saves money and protects the environment. Strong foam formation is a sign of excessive dosing and impairs machine operation.

3.4.7 Handling and braking the vehicle

In short This section explains how the machine is driven and stopped with the accelerator pedal. It warns about steep slopes and wet surfaces, and describes what to do if the drive motor shuts off from overload.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍⁠‌​​​‌​⁠​​‌⁠​​​⁠⁠​‍‌​‌⁠​⁠‌‌​‍⁠‌‍⁠⁠
Note Set the key switch to ‘0’ to immediately disable all the functions.
Danger
  • Danger of tilting over when driving on excessively steep slopes
    Transport journeys on slopes of up to 10 % must only be executed for 1 minute and with special caution.
  • Risk of skidding when driving on wet surfaces.
    Drive very carefully into the bend when driving downhill.

Observe the following points when driving:‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍⁠‌​​​‌​⁠​​‌⁠​​​⁠⁠​‍‌​‌⁠​⁠‌‌​‍⁠‌‍⁠⁠

  • Driving speed and braking of the machine are controlled via the accelerator pedal.
  • When releasing the accelerator pedal, the engine brake is activated automatically. This also applies to slopes and when driving downhill.
  • Stop the machine: Release the accelerator pedal.
  • When the machine is at standstill, the parking brake is activated audibly. It is no longer possible to push the machine, see section 3.4.8.

Overload protection

In case of an overload, e.g. excessively steep slopes, the drive motor is switched off after a certain period of time.

  • Let the machine cool down for approx. 15 minutes.
  • Restart the machine.

3.4.8 Pushing the machine

In short The machine has no braking effect while it is being pushed. To push it you remove the drive cover, move the pin to the ring to release the parking brake, and reverse the steps afterwards.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍⁠‍​​​‌​⁠​​‌⁠​‌⁠​‌‌‌⁠‍‍​‍​‍⁠‌‍‍⁠⁠‍‌
Danger Risk of accident! When pushing the machine, it does not have any braking effect.
After pushing the machine, only re-start it if the lever has been positioned and the cover installed.
Two photos of the drive cover opening on the machine. In the left photo, callout A points to the pin in its holder and B points to the ring. In the right photo, a hand holds the pin screwed into the ring while an arrow points upward and callout C marks the pin.
Fig. 19:

In order to push the machine, carry out the following steps:‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​‍⁠‍​​​‌​⁠​​‌⁠​‌⁠​‌‌‌⁠‍‍​‍​‍⁠‌‍‍⁠⁠‍‌

  1. Loosen the bolts of the cover to the drive using the supplied socket wrench and remove the cover.
  2. Remove the pin Fig. 19-A from the holder and screw it into the ring Fig. 19-B.
  3. In order to unlock the parking brake, slightly pull the pin upwards and simultaneously push the machine.
  4. Disassembly is in reverse order.

3.4.9 Turning off the machine

In short Bring the accelerator pedal slowly to zero, let the machine stop, switch off the cleaning functions, then switch off with the key switch.
  1. Slowly bring the accelerator pedal to the zero position. The machine slows down to standstill. A better braking effect is achieved when the machine is slowed down by applying the brake.
  2. When the machine is at standstill, the parking brake is activated audibly.
  3. Switch off the cleaning functions.
  4. Switch off the machine using the key switch.
Note Remove the key when leaving the machine to prevent unauthorised use.

5.3 Battery system

5.3.1 Type of battery

In short This section describes the two trough battery types the machine variants use and how each is wired. If other Hako-approved batteries are fitted, the configuration menu must be set to match, and only a Hako-authorised workshop should do this.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​⁠‍⁠​​​‌​⁠​​‍‌⁠‌‍‌‍⁠‌​‍⁠⁠‌⁠⁠​‌‌​​‌‌‌

The machine variants are equipped with different maintenance-free battery types. When using other batteries which have been approved by Hako, corresponding settings must be carried out in the configuration menu. These settings should only be carried out by a workshop authorised by Hako!‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​⁠‍⁠​​​‌​⁠​​‍‌⁠‌‍‌‍⁠‌​‍⁠⁠‌⁠⁠​‌‌​​‌‌‌

5.3.2 Battery plug coding

In short The battery, machine and charger plugs carry coloured coded pins that must match the battery type and voltage. If other Hako-approved batteries are used, the plugs must be re-coded, and only by a workshop authorised by Hako.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​⁠⁠‌​​​‌​⁠​​‍‍‌‌‌‍​​‍​‌​⁠‍​‍⁠‍‌​‍⁠⁠⁠

Batteries and chargers: make sure your charger is compatible with your batteries, and set its charging algorithm to your battery pack before you use it.

The plug connectors between the battery Fig. 20-A, the machine Fig. 20-B and the charger Fig. 20-C are coded with coloured coded pins (yellow, grey or green) Fig. 20-D depending on the type of battery and rated voltage.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​​⁠⁠‌​​​‌​⁠​​‍‍‌‌‌‍​​‍​‌​⁠‍​‍⁠‍‌​‍⁠⁠⁠

Battery plug coding: close-up of the battery plug (A) and the machine plug (B), a strip showing the 6 V and 24 V voltage coding marks (D), and a photo of the charger with its plug (C)
Fig. 20:

When using other batteries which have been approved by Hako, the plugs must be re-coded.

The following three prerequisites must be met for the whole system:

  • Voltage coding (24 V) must be identical for all plugs and bushes.
  • The colour of the coded pin in the connector housing of the machine is always yellow.
  • The colour of the coded pin in the charger plug (machines without built-in charger) and in the bush housing of the battery must be identical:
    • Grey for wet batteries
    • Green for maintenance-free gel batteries
Warning Risk of short circuit! The coding of the plugs should only be carried out by a workshop authorised by Hako!

5.3.3 Battery management system (BMS)

In short The battery management system monitors the battery, determines its charge state and switches off the cleaning functions at the discharge limit. If other Hako-approved batteries are used, the BMS must be reset by a workshop authorised by Hako.

Batteries and chargers: make sure your charger is compatible with your batteries, and set its charging algorithm to your battery pack before you use it.

The battery management system (BMS) ensures the battery system is monitored and secure. The BMS is responsible for:

  • determining the battery charging state during operation
  • switching off the cleaning functions when the discharge limit has been reached to protect the battery against total discharge
Attention When using other batteries which have been approved by Hako, the BMS must be reset in order to protect the battery against total discharge. The settings of the BMS should only be carried out by a workshop authorised by Hako!

5.3.6 Checking the acid level

In short The battery acid level must be checked weekly, and demineralised water refilled if needed. On batteries with an aquamatic system, a white dot visible at the top of each plug shows the level is right; otherwise refill through the aquamatic end piece after charging has finished.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​‌​​‍​​​‌​⁠​​⁠‍⁠​⁠‌‌‌‌⁠‍⁠‍‌‌​⁠‍⁠‌‍​‍⁠

Batteries and chargers: make sure your charger is compatible with your batteries, and set its charging algorithm to your battery pack before you use it.

Warning Risk of explosion and fire! When handling batteries, it is prohibited to smoke and use an open fire.
Attention
  • Observe the information in the operating manual of the battery manufacturer!
  • Refilling must only take place once the battery charging process has been terminated.
Note Batteries approved by Hako are equipped with an aquamatic system.

Fig. 24:

The customer has to check the acid level of the battery weekly, demineralised water (according to DIN 43530-4) must be refilled if necessary.‌‌​⁠‌⁠‍‌​⁠​​⁠⁠​‍‍‌⁠‍​​​​‌​​‍​​​‌​⁠​​⁠‍⁠​⁠‌‌‌‌⁠‍⁠‍‌‌​⁠‍⁠‌‍​‍⁠

If the trough battery is equipped with an aquamatic system Fig. 24-A, each individual cell features a sealing plug with float indicator. The white dot must be located at the top and must be clearly visible. If this is not the case, refill demineralised water.

To do so, connect the end piece of the aquamatic system Fig. 24-B to a container with demineralised water. Observe sufficient gradient, ensuring the water can flow into the cells. If the required level has been reached, the plugs automatically seal the cells and indicate “full”.
