Only use cleaning agents (non-

foaming) 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

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 (non-

foaming) 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 Ah5),

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

the scrubber-drier to provide feedback

on the operating status of the vehicle.

This only relates to operating states

which cannot be switched on and off via

the operating panel: recovery tank full,

dirt hopper for pre-sweep/vacuum unit

full, parking brake applied and error

message.

The individual buttons and functions are

described in detail below:

Indicator for recovery tank

maximum fill level

(Fig. 21/2) The yellow

control lamp lights up when

the recovery tank has

reached its maximum fill level. Also, a

"beep" signal is issued every 15

seconds. In this case, a float switch

switches the suction turbine off and the

squeegee is raised.

Dirt hopper and front flap

indicator of the pre-

sweep/vacuum unit

(Fig. 21/3) The control lamp

lights up red when the dirt hopper is not

properly inserted (engaged) or the front

flap is not properly closed.

Indicator for parking brake

applied

(Fig. 21/4) The control lamp

lights up red when the

parking brake has been

actuated via the pedal to the left of the

steering column. If the traction drive is

switched on, an acoustic signal is also

issued.

Operation

Indicator for function

faults

(Fig. 21/5)

The control lamp lights up

red when one of the following

faults occurs:

• Thermostatic switch of the brush

motor, drive motor or cylindrical

brush has switched off

• One of the safety fuses is defective

or an electronic fuse has been

tripped.

• Another fault has occurred.

At the same time, a four-digit code

appears in the display of the service

indicator (Fig. 21/6). This error code

infers which fault has occurred (refer to

Section 3.5.1). At the same time, the

control lamps flash and an acoustic

signal is issued.

Operating hour

counter

(Fig. 21/6) The four-digit

LED serves to display

the operating hours.

When the key in the key switch is turned

on, one and then two four-digit codes

appear in succession (for further

details, refer to page 48, Key switch

(Fig. 22/6)). The operating hours

appear after this.

The counter only operates when

consumers are switched on (e.g. drive

or brush motor, suction turbine or pre-

sweep/vacuum unit). At the same time,

a red dot flashes at the bottom right of

the display.

Service indicator

(Fig. 21/6) The four-digit

LED serves for a more

accurate determination

of function faults. If a

fault occurs during operation, a four-

digit code (error code) appears in the

service indicator display. At the same

time, the four dots of the error code

flash in the display and an acoustic

signal is issued. The control lamp

indicating functional faults lights up red.

Section 3.5.1 provides an overview of

the error codes which help you clear

the location of use:

• Reduce water quantity (Fig. 26/2)

• Increase water quantity (Fig. 26/4)

• Fresh water feed on/off (Fig. 26/3)

• Increase brush pressure (Fig. 26/1)

Vacuuming dry

• Press the “Button for

squeegee and suction

turbine” (Fig. 21/10) on

the left-hand operating

panel.

Check whether the floor is

sufficiently dry at regular

intervals, otherwise people

excessively wet, check the

vehicle for leaks and that the

sealing strips are in a good

condition. If the sealing strips

are damaged, change them;

refer to Section 5.8.4.

Operation

Vacuuming with the suction hose

The suction hose is an optional

accessory and part of the

spray/vacuum tool function.

When the suction hose is in

operation, the scrubber drier's

parking brake must be applied.

Vacuuming with the suction

turbine” (Fig. 21/10) on

the left-hand operating

panel to switch the

suction turbine on and

off.

The squeegee remains raised.

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.

vehicle is switched off and,

thus, drain the battery.

3.3.6 Loading and transporting the

vehicle

Refer to Section 5.13.

Operation

3.4 After finishing work

1. Drive to a suitable service or parking

area.

An appropriate service and

parking area must have a solid

floor, have a roof and ensure

that no hazardous substances

(e.g. oils, battery acid, cleaning

agents, etc.) can get onto the

floor or in the sewage system.

2. Stop the vehicle and switch it off.

Before getting out of the

vehicle apply the parking

brake, switch off the key switch

and remove the key.

Check that the working lights

are switched off.

The working lights can be
