Fig 9

Adjusting the squeegee

The squeegee must be set up on a level

oor according to the conditions in which

it is to be used. The squeegee must stand

vertically on the oor (adjusted at the fac-

tory). The sealing strip (Fig. 9/3) should

bend slightly to the rear when the vehicle

is in operation. Supporting rollers (Fig.

9/5) limit its movement toward the oor. To

increase the squeegee contact pressure,

the supporting rollers must be adjusted:

• Loosen the counternuts (Fig. 9/4) and

raise the supporting rollers on the left

and right evenly (turn screw counter-

clockwise and lock again).

The sealing strip now bends a little more

towards the rear. An adjustment of the

supporting rollers is also necessary when

the edge of the sealing strip is worn.

2.4 Before starting up daily

Carry out the following checks before start-

ing the vehicle up for its daily operation

(also refer to Section 5.3.2):

1. Check the recovery tank, empty as

necessary. Clean it as necessary. Re-

fer to Sections 5.6.1 and 5.6.2.

2. Check the waste container; empty and

clean it, if necessary; refer to Section

5.7.1.

3. Fill the solution tank and cleaning

agent in accordance with the manu-

facturer’s mixing directives. Refer to

Section 3.1.4 and Section 5.5.1.

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. These products meet

the requirements stipulated in

the washing and cleaning agent

directive (WRMG - Wasch- und

Reinigungsmittelgesetzes).

4. Check the battery charge and recharge

as necessary; refer to Section 5.4.1.

Before starting the vehicle for its

rst working operation, carry out

an initial battery charging routine;

refer to Section 2.2.

5. Check the area where the vehicle was

parked 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 open ground or a test

track until they are familiar with

the individual operating elements

and the respective functions.

3.1 Method of operation

The Admiral 38C is a scrubber-drier

designed for wet cleaning rough and struc-

tured hard oors inside buildings, such as

multi-storey car parks or in logistics and

industrial areas (refer to Fig. 11). It cleans

oors 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. The Admiral 38C is a ride-on

machine designed for the economic clean-

ing of large oor areas in buildings. A seat

contact ensures that the vehicle can only

be operated when an operator is seated

on the driver’s seat.

Fig 11

The most important vehicle elements are

described below:

3.1.1 Rotary brush head

(Fig. 12/2)

The two rotary brushes, which can be

changed without the need for any tools,

in the rotary brush head provide a high

cleaning performance. The solution sup-

ply starts automatically when the rotary

brush head is lowered. The solution is

sprayed onto the oor to be cleaned by

means of three nozzles. At the same time,

the contra-rotating rotary brushes start to

rotate. They then scrub the oor in such a

way that even dirt which has penetrated

more deeply is removed. The two rotary

brushes are each driven by a splashproof

electric motor. The contra-rotating motion

of the rotary brushes also picks up coarse

dirt and throws it into the downstream

waste container (sweeping function). In

addition to the cleaning effect, this also

ensures that coarse dirt, such as cable

ties, cigarette ends etc., does not slide

under the sealing strip of the squeegee

and, thus, impair the vacuuming results.

The waste water left over is then removed

by the squeegee which follows on.

Admiral 38C Scrubber PB# 4100055UM Rev.* 08/10

Page 22

Operation

Fig 12

Deectors (Fig. 12/2)

To the right and left of the rotary brush

head, near the oor, are two deectors

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 deectors can be raised, if neces-

sary. This is the case for basic cleaning,

for example, where the oor only needs to

be scrubbed when wet and the solution is

not vacuumed up but allowed to soak in

instead. To raise the deector, take hold of

the grip (Fig. 12/6), raise it and hook the

locking hooks (Fig. 12/4) in the recesses in

the grip above it (Fig. 12/5). Proceed in the

same way on the other side of the side of

the vehicle.

Side brush unit (Fig. 12/1)

In order to be able to sweep up coarse dirt

close to walls and beyond the width of the

squeegee, a side brush unit, consisting of

two side brushes (right and left) can be

installed as an option at the front, refer to

Section 3.1.9.

Admiral 38C Scrubber PB# 4100055UM Rev.* 08/10

Page 23

Operation

3.1.2 Squeegee

(Fig. 12/3)

The squeegee, which projects at the sides,

is xed to the Admiral 38C so that it can

pivot and swing. This enables it to evade

obstacles in the current cleaning track

and pivot back. Its strong suction capacity

ensures the waste water is vacuumed up

fully even on uneven oors and in bends,

leaving the oor dry enough to be walked

on. The squeegee must be checked prior

to starting work, when disposing of waste

water and/or lling the solution 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.

Operation

3.1.3 Suction turbines (suction)

(Fig. 13/3)

The two suction turbines are located on

the rear panel of the solution 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 oat

switch in the recovery tank switches the

suction turbine off automatically on reach-

ing the maximum ll height.

3.1.4 Solution tank

(Fig. 13/2)

The solution tank is located behind the

driver’s seat, on the right-hand side (when

facing the front). It has a capacity of ap-

prox. 174 liters. Pivot the gray tank cap

open and lock to ll. Fill water, max. 50 °C,

and add the cleaning agent in accordance

with the manufacturer’s instructions. Pivot

the tank cap back down.

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 Admiral 38C. These products meet the

requirements stipulated in the washing and

cleaning agent directive (WRMG - Wasch-

und Reinigungsmittelgesetzes). Observe

the correct dosage of the cleaning agent.

The correct dosage helps to reduce costs

and protect the environment. The devel-

opment of excessive foam impairs the

machine’s function. It indicates overdos-

age of the cleaning agent; components of

the cleaning agent which are fed back to

the waste water cause foaming. Informa-

tion on dosage is provided on the cleaning

agent container. Use the manufacturer’s

information as an initial guideline. Practi-

cal experience will ensure that you quickly

nd out which is the right cleaning agent

and the optimum dosage to suit your

needs. The solution feed to the brushes

is automatically opened when the scrub-

bing program is activated. If necessary, the

feed can be stopped manually by means

of the ball cock.

Operating times with one tankful:

•at 2 l/min. approx. 87 minutes

•at 4 l/min. approx. 43 minutes

•at 7 l/min. approx. 24 minutes

3.1.5 Recovery tank

(Fig. 13/1)

The recovery tank is located behind the

driver’s seat, on the left-hand side (when

facing the front). It has a capacity of ap-

prox. 174 liters. The waste water is fed

to the recovery tank via the squeegee

by means of a vacuum. A oat switch at

the top of the recovery tank switches the

suction turbine off automatically as soon

as the maximum tank ll level is reached.

In this case, the control lamp (Fig. 15/2)

on the left operating panel lights up. An

acoustic signal is also issued. A vacuum-

ing 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 difcult to access.

Page 25

Operation

3.1.6 Traction drive

The traction drive is provided by a drive

motor on the steerable front wheel. The

driving speed can be continuously regu-

lated via the accelerator by means of the

electronic drive control (pulse contact con-

trol). The axle gear is a low maintenance

gear train which runs in an oil bath: The

gear oil need not be changed.

In the case of faults involving the

traction drive, stop the vehicle

immediately and remove the key

from the key switch!

3.1.7 Brakes

The Admiral 38C is equipped with a ser-

vice brake and a parking brake. The ser-

vice 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.

3.1.8 Batteries and charger

The vehicle is equipped with low-main-

tenance batteries. The batteries concern

6 individual cells with an output of 36

Volt/320 Ah5. They are located under the

seat console.

To ensure protection against total dis-

charge, the Admiral 38C is equipped with

a total discharge signal transducer (TSG).

It is integrated in the electronic system and

set up at the factory.

If other batteries are used, the

total discharge signal trans-

ducer must be adjusted. This

adjustment work should only be

performed at an authorized Pow-

erBoss service center.

The battery is provided with a connection

cable with battery plug (Fig. 14/1). When

the battery plug is plugged into the vehicle

socket (Fig. 14/2), the vehicle is ready to

operate. To charge the battery, insert the

battery plug in the charger. The vehicle

includes a battery charger. Pay attention

to the safety information of the producer of

battery and battery charger.

Indicator eld

(Fig. 17/1) The indicator eld enables the

Admiral 38C to provide feedback on the

operating status of the vehicle. This only

relates to operating states which cannot be

switched on or off via the operating panel:

recovery tank full, parking brake applied

and error messages.

The individual buttons and functions are

described in detail below:

Indicator for recovery tank

maximum ll level

(Fig. 17/2) The yellow control

lamp lights up when the recovery

tank has reached its maximum ll level.

Also, a “beep” signal is issued every

15 seconds. In this case, a oat switch

switches the suction turbine off and the

squeegee is raised.

Indicator for parking brake

applied

(Fig. 17/3) 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.

Indicator for function faults

(Fig. 17/4)

The control lamp lights up red

when one of the following faults

occurs:

• The thermostatic switch disconnects

from the brush or hydraulic motor.

• 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 ap-

pears in the display of the service indicator

(Fig. 17/5). This error code infers which

fault has occurred (refer to Section 3.5.1).

At the same time, the control lamps ash

and an acoustic, pulsating signal is issued.

Operating hours counter

(Fig. 17/5) 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 suc-

cession (for further details, refer to Page

36, Key Switch (Fig. 18/1)). The operating

hours appear after this.

The counter only operates when consum-

ers are switched on (e.g. hydraulic or

brush motor, suction turbine). At the same

time, a red dot ashes at the bottom right

of the display.

Service indicator

(Fig. 17/5) The same LED

also 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 indica-

tor display. At the same time, the four

dots of the error code ash in the display

and a pulsating acoustic signal is issued.

The control lamp in the functional fault

display lights up red. Section 3.5 provides

• Increase solution quantity (Fig. 22/3)

• Solution on/off (Fig. 22/2)

• Increase brush pressure (Fig. 22/4)

Check whether the oor is suf-

ciently dry at regular intervals,

otherwise people could slip. If the

oor is 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.

Admiral 38C Scrubber PB# 4100055UM Rev.* 08/10

Page 45

Operation

Wet scrubbing (basic cleaning)

If you do not want to vacuum the oor dry

in the same working procedure because

you want the solution to soak into the dirt,

for example, activate this program.

Wet oors are a potential risk for

slipping! Ensure to provide the

corresponding information and

warning signs.

• Press the “Button for rotary

brush drive” button (Fig. 15/9)

on the left-hand operating

panel.

Various functions can be switched on or off

with the following buttons according to the

conditions at the location of use:

• Reduce solution quantity (Fig. 22/1)

• Increase solution quantity (Fig. 22/3)

• Solution on/off (Fig. 22/2)

• Increase brush pressure (Fig. 22/4)

Vacuuming dry

• Press the “Button for squee-

gee and suction turbine” on

the left-hand operating panel.

Check whether the oor is suf-

ciently dry at regular intervals,

otherwise people could slip. If the

oor is 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.

Vacuuming with the hand-held suction

hose

The hand-held suction hose is an optional

accessory.

Vacuuming with the hand-held suction

hose only works when the operator is not

seated on the driver’s seat (seat contact

switch is not actuated).

Always apply the parking brake

before getting out of the vehicle!

• Press the “Button for squee-

gee and suction turbine” on

the left-hand operating panel.

The squeegee remains raised.

Useful tips for cleaning

• Sweep the oor before starting wet

cleaning. This not only improves the

cleaning effect but also reduces the

vehicle‘s liability to wear.

• The oor should be treated twice in

the case of particularly dirty oors or to

remove wax (basic cleaning).

- During the rst cleaning process,

the oor is scrubbed with a cleaning

agent dosage appropriate to the de-

gree of soiling, whereby the squee-

gee is raised.

- Let the cleaning solution work into

the oor for 5 to 10 minutes accord-

ing to the manufacturer’s information.

- Then scrub the oor again with the

squeegee lowered.

• Observe the correct dosage of the

cleaning agent. Information on dos-

age is provided on the cleaning agent

container.

• Use the manufacturer’s information

Admiral 38C Scrubber PB# 4100055UM Rev.* 08/10

Page 46

Operation

as an initial basis. Practical experience will

ensure that you quickly nd out which is

the right PowerBoss cleaning agent and

the optimum dosage to suit your needs.

The correct dosage helps to

reduce costs and protect the

environment.

The development of excessive

foam impairs the machine’s func-

tion.

• 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

• Turn the key from lock position 1 to po-

sition 0. The vehicle is no longer ready

to operate.

• Remove the key from the key switch.

Apply the parking brake!

area.

An appropriate service and park-

ing area must have a solid oor,

have a roof and ensure that no

hazardous substances (e.g. oils,

battery acid, cleaning agents,

etc.) can get onto the oor or in

the sewage system.

2. Stop the vehicle and switch it off.

Before getting out of the vehicle

General information on handling

batteries

Pay attention to the safety infor-

mation n paragraph 1.4 and 1.5.2

as well as the information on

servicing and maintenance in the

battery documents.

• Always disconnect the battery plug be-

fore starting any work on the electrical

installation.

• Batteries may only be handled and

changed by properly skilled mainte-

nance personnel.

• Pay attention to legal requirements and

local directives.

5.4.1 Charging batteries

Before starting the vehicle up for

the rst time, the batteries to be

used must be properly charged

by implementing the initial battery

charge routine, see paragraph

2.2. PowerBoss assumes no

liability for damage to the battery

caused by a fault when the bat-

tery is charged for the rst time.

There must be sufcient ventila-

tion in the charging area - risk of

explosion!

The seat console (Fig. 23/4)

must be open during the battery

charging process to prevent the

development of explosive oxyhy-

drogen!

Only use the original charger!

Pay attention that the insulation

is not initially damaged and not

damaged during the charging

process. The cable must not rub

against anything. Do not use the

charger if the insulation is dam-

aged.

We recommended charging the bat-

tery when at least one dot of the battery

indicator has gone out after operating

the vehicle. The indicator (Fig. 23/1) also

indicates the charge status of the batteries

during the charging process.

• Connect the battery plug (Fig. 23/3) to

the battery charger supplied.

• Pay attention to the information in the

operating manual supplied with the

charger and the manual from battery

manufacturer.

Do not inhale battery gases.

5.4.2 Servicing the driving batteries

Checking the acid level

The Admiral 38C is tted with a main-

tenance-free battery. However, if a wet

battery is used instead, the acid level must

be checked by the customer on a weekly

basis and distilled water must be topped

up, if necessary; also see paragraph 5.3.1.

There must be no naked ames

used in the vicinity when han-

dling batteries, particularly when

checking the acid level.

The battery cells are provided with ll level

indicators which ensure the correct height

of electrolyte is maintained: Rell distilled

water, if required. Details on the lling pro-

cess are contained in the manual provided

by the battery manufacturer.

Spilled battery acid must never

enter the sewage system in its

initial form, it must be neutral-

ized beforehand: e.g. diluted with

plenty of water or absorbed with

granulate.

Checking the acid density and voltage

of each battery

These points must be checked and cor-

rected at regular intervals within the scope

of PowerBoss system maintenance by an

authorized service center.

5.7.2 Changing the rotary brushes

Check the rotary brushes on a

weekly basis for signs of wear.

When a rotary brush has worn to a diam-

eter of approx. 3.9 in, the rotary brushes

must be replaced by new ones (diameter

of new rotary brush: 5.4 in).

To protect the oor surface, the

rotary brushes are equipped

with a wear restriction facility.

When the minimum diameter is

reached, the rotary brush head

lowers onto a vertical stop. The

full cleaning performance can no

longer be achieved when in this

position.
