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 factory). 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 counterclockwise 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.

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 structured 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 cleaning 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 supply 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.

Operation
Fig 12
Deectors (Fig. 12/2)
To the right and left of the rotary brush
head, near the oor, are two deectors
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 deectors can be raised, if necessary. 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 deector, 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.

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 reaching 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 approx. 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 (nonfoaming) 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 - Waschund Reinigungsmittelgesetzes). Observe
the correct dosage of the cleaning agent.
The correct dosage helps to reduce costs
and protect the environment. The development of excessive foam impairs the
machine’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
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 scrubbing 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 approx. 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 vacuuming 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 difcult to access.

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 regulated via the accelerator by means of the
electronic drive control (pulse contact control). 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 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.
3.1.8 Batteries and charger
The vehicle is equipped with low-maintenance 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 discharge, 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 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. 14/1). When
the battery plug is plugged into the vehicle
socket (Fig. 14/2), the vehicle is ready to
