2.4 Before starting up daily

Carry out the following checks before starting the vehicle up for its daily operation (also refer to Section 5.3.1):

1. Check the recovery tank, empty it if necessary. Clean it as necessary. Refer to Sections 5.6.1 and 5.6.2.

2. Fill the fresh water tank and add a cleaning agent in accordance with the manufacturer's mixing directives. Refer to Section 3.1.5 and Section

5.5.1.

Only use cleaning agents (nonfoaming) suitable for the vehicle's vendor. We recommend using our clean and care products which are specially balanced for the vehicles.

3. Check the battery charge and recharge as necessary; refer to Section 5.4.1.

Before starting the vehicle for its first working operation, carry out an initial battery charging routine; refer to Section 2.2.

4. Check the parking space for signs of leaks. Hoses, lines and tanks must show no signs of leaks or damage. If necessary, clear up any defects before putting the vehicle into operation.

Operation

3 Operation

Operating personnel must read the operating manual through carefully. Operating personnel should complete their initial test drive on a sufficiently large piece of open space until they are familiar with the individual operating elements and the respective functions.

3.1 Method of operation

The Admiral 48D is a scrubber-drier for wet cleaning hard floors (refer to Fig.

14). It cleans floors by means of intensive scrubbing with the aid of a water and cleaning agent solution. The squeegee at the rear of the vehicle vacuums up the waste water into the recovery tank in the same working process. By using the pre-sweep/vacuum unit, the vehicle can also be operated according to the tandem principle for the advanced sweeping and dry cleaning of hard floors: the dirt is swept up dust-free using two side brushes and a cylindrical brush.

Fig. 14

The scrubber-drier is a ride-on machine designed for the economic cleaning of large floor areas in buildings. A seat contact ensures that the vehicle can only be operated when an operator is seated on the driver's seat.

The most important vehicle elements are described below:

3.1.1 Pre-sweep/vacuum unit (Fig. 15/4)

The pre-sweep/vacuum unit sweeps and vacuums up dirt in dry areas in front of the scrubbing unit without swirling up dust. In this case, the two side brushes sweep the dirt directly in the track of the cylindrical brush. The side brushes sweep up the dirt from corners and edges so that it is not necessary to drive too close to shelves, walls, machines, etc. and a driving clearance to allow steering can easily be maintained. The cylindrical brush then sweeps the dirt forwards into the dirt hopper. The fine dust swirled up by the cylindrical brush is drawn up by the extractor fan and fed to the filter element. Only clean air is blown from the machine. The Admiral 48D complies with dust category U

(BIA). The pre-sweeping and vacuuming system and the filters are easily accessible for maintenance tasks.

Operation

Fig. 15

3.1.2 Scrubbing unit (Fig. 15/5)

Three disk brushes, which can be changed without the need of tools, ensure a high cleaning performance. They are each driven by a brush motor. The brush pressure can be adjusted electrically according to the floor and accumulation of dirt. When the brushes are raised, the water supply and brush rotation are stopped automatically. The deflection bars to the left and right of the disk brushes can be raised, if necessary. This ensures the cleaning solution is not forced to the center of the vehicle and, as a result, can soak the dirt. This is necessary for basic cleaning (wet scrubbing only), for example. Hook in the deflectors, refer to paragraph ”Scrubbing unit”.

In the case of all cleaning work involving immediate vacuuming, the deflectors must be unhooked so that the deflectors make contact with the floor.

Operation

Deflectors (Fig. 15/5)

To the right and left of the disk brushes, near the floor, are two deflectors which, when in their working position, prevent water splashing to the sides and guide the waste water to the center of the vehicle so that it can be vacuumed up better. The deflectors can be raised, if necessary. This is the case for basic cleaning, for example, where the floor only needs to be scrubbed when wet and the solution is not vacuumed up but allowed to soak in instead. To raise the deflector, take hold of the grip (Fig. 15/1), raise it and hook the locking hooks (Fig. 15/3) in the recesses in the angle (Fig. 15/2) above it. Proceed in the same way on the other side of the side of the vehicle.

3.1.3 Squeegee (Fig. 15/6)

The squeegee, which projects at the sides, is fixed to the scrubber-drier so that it can pivot and swing. This enables it to evade obstacles in the current track and pivot back. Its strong suction capacity ensures the waste water is vacuumed up fully even on uneven floors and in bends, leaving the floor dry enough to be walked on. The squeegee must be checked prior to starting work, when disposing of waste water and/or filling the fresh water tank and cleared of any foreign bodies which have been vacuumed up. Check that the sealing strips are in perfect condition. The rollers serve to support the squeegee to prevent excessive bending of the sealing strips. The squeegee is automatically raised when reversing.

3.1.4 Suction turbines (suction) (Fig. 16/3)

The two suction turbines are located on the rear panel of the fresh water tank and can be accessed after opening the rear doors. The suction turbines are switched on and off automatically when lowering and raising the squeegee, respectively. A float switch in the recovery tank switches the suction turbine off automatically on reaching the maximum fill height.

Operation

3.1.5 Fresh water tank (Fig. 16/2)

The fresh water tank is located behind the driver's seat on the right-hand side. The fresh water tank is a tank partitioned by a membrane panel and has a volume of approx. 81.9 gal. Open up the red tank cap and secure it to fill the tank. Fill water, max. 122 °F, and add the cleaning agent in accordance with the manufacturer's instructions. Lower the cap again to close it.

Only use cleaning agents (nonfoaming) suitable for the vehicle's vendor.

We recommend using our clean and care products which are specially balanced for the scrubber drier. Observe the correct dosage of the cleaning agent. The correct dosage helps to reduce costs and protect the environment.

Fig. 16

Operation

The development of excessive foam impairs the vehicle's function. It indicates overdosage of the cleaning agent; components of the cleaning agent which are fed back to the waste water cause foaming. Information on dosage is provided on the cleaning agent container. Use the manufacturer's information as an initial guideline. Practical experience will ensure that you quickly find out which is the right cleaning agent and the optimum dosage to suit your needs. The fresh water supply to the brushes is automatically opened when the scrubbing program is activated. If necessary, the feed can be stopped manually by means of the ball cock. Operating times with one tankful:

• at 0.5 gal/min approx. 155 minutes

• at 1.1 gal/min approx. 77 minutes

• at 1.8 gal/min approx. 44 minutes

3.1.6 Recovery tank (Fig. 16/1)

The recovery tank is located behind the driver's seat on the left-hand side. The recovery tank is a tank partitioned by a membrane panel and has a volume of approx. 81.9 gal. The waste water is fed to the recovery tank via the squeegee by means of a vacuum. A float switch at the top of the recovery tank switches the suction turbine off automatically as soon as the maximum tank fill level is reached. In this case, the control lamp (Fig. 19/2) on the left operating panel lights up. An acoustic signal is also issued. A spray/vacuum tool (refer to Section 4), which can be connected to the vehicle, is optionally available with which to clean and vacuum up water from areas difficult to access.

Operation

3.1.7 Traction drive

The traction drive is provided by a drive motor on the steerable front wheel. The driving speed can be continuously regulated via the accelerator by means of the electronic drive control (pulse contact control). The axle gear is a gear train which runs in an oil bath.

In the case of faults involving the traction drive, stop the vehicle immediately and remove the key from the key switch!

3.1.8 Brakes

The scrubber-drier is equipped with a service brake and a parking brake. The service brake relates to a drum brake which acts hydraulically on the rear wheels. It is actuated by a foot pedal. The parking brake is actuated mechanically via brake cables. It is applied by means of the foot pedal to the left of the steering column and released using the safety catch in the steering column.

Operation

3.1.9 Batteries and charger

The scrubber-drier is powered by a traction battery (36 Volt / 395 Ah

), 6 monobloc batteries each producing 6 Volt. They are fit in a battery tray. To ensure protection against deep discharge, the scrubber drier is equipped with a deep discharge signal transducer (Battery Management System (BMS)). It is integrated in the electronic system and set up at the factory for GiS batteries (service indicator: No. 5).

If other batteries are used, the deep discharge signal transducer must be adjusted. This adjustment work should only be performed at an authorized PowerBoss service center.

The battery is provided with a connection cable with battery plug (Fig.

17/1). When the battery plug is plugged into the vehicle socket (Fig. 17/2), the vehicle is ready to operate.

Useful tips for cleaning

• Sweep the floor before starting wet cleaning. This not only improves the cleaning effect but also reduces the vehicle's liability to wear.

• The floor should be treated twice in the case of particularly dirty floors or to remove wax (basic cleaning).

- During the first cleaning process,

the floor is scrubbed with a cleaning agent dosage appropriate to the degree of soiling, whereby the squeegee is raised.

- Let the cleaning solution work into

the floor for 5 to 10 minutes according to the manufacturer's information.

- Then scrub the floor again with the

squeegee lowered.

• Observe the correct dosage of the cleaning agent. Information on dosage is provided on the cleaning agent container.

• Use the manufacturer's information as an initial basis. Practical experience will ensure that you quickly find out which is the right PowerBoss cleaning agent and the optimum dosage to suit your needs.

Operation

The correct dosage helps to reduce costs and protect the environment.

The development of excessive foam impairs the vehicle's function. Cause: Too much cleaning agent leads to certain component parts of it getting into the waste water resulting in the development of foam. This indicates that the amount and mixture of solution do not match the level of dirt.

3.3.5 Switching the vehicle off

Apply the parking brake!

1. Turn the key from position 1 to lock position 0. The vehicle is no longer ready to operate.

2. Remove the key from the key switch.
