Intended use
The Scrubmaster B 310 R is a large-
area scrubber-drier designed for wet
cleaning rough and structured hard
floors inside buildings, such as in multi-
storey car parks or logistics and indus-
trial areas. This machine is intended for
commercial use. Any use beyond this is
regarded as improper use. The manu-
facturer is not considered liable for any
damage resulting from improper use;
the user is solely responsible for all the
risks.
The scrubber drier has not
been approved for use on pub-
lic paths and roads.
Intended use also includes maintaining
and observing the operating, mainte-
nance and repair conditions prescribed
by the manufacturer.
The scrubber drier may only be operat-
ed, serviced and repaired by personnel
who are familiar with the work involved
and are aware of the risks.
The applicable accident prevention
laws must be observed and any gener-
ally accepted health and safety direc-
tives must be maintained.
Based on the conception, design and

plicable safety and health require-
ments stipulated in the EU directives
with regard to its planning, construc-
tional design and final construction
as introduced by us onto the market.
In the case of modifications to the ve-
hicle not approved by us, the EC
Declaration of Conformity enclosed
in this operating manual loses its va-
lidity.
• In addition to the information provid-
ed in this operating manual, all legal-
ly applicable health and safety provi-
sions must be observed.

1.3 Operating information
• Before starting the vehicle up for the
firsttime,the batterytobeusedmust
be fully charged, properly, by imple-
menting the initial battery charge
routine. Please pay attention to the
operating manual provided with the
charging unit as well as the manual
from the battery manufacturer. Hako

and that it is safe to drive and oper-
ate. Clear up any faults and defects
immediately! Never operate the vehi-
cle without functional safety equip-
ment.
• Warning: Do not use the vehicle
without a protective roof structure
(refer to "Accessories", "Cab safety
roof") in areas where the driver is at
risk of being hit by falling objects
(e.g.warehouses).Contactthetrade
association responsible for you as to
whether obligations exist in this re-
spect.
• The scrubber drier must be subject-
ed to an inspection in respect of its
operationally safe condition at least
once a year by an authorized techni-
cal expert. The results of the inspec-
tion must be documented in writing
and kept safe at least until the next

sonnel must be fully familiar with all
adjustment, operating and control el-
ements as well as their respective
function! It is too late to do this when
the vehicle is actually in operation!
• The warning labels attached to the
scrubber drier provide important in-
formation concerning safe operation.
• Wet floors are a potential risk for slip-
ping! Ensure to provide the corre-
sponding information and warning
signs.
• If the floor is excessively wet, check
the vehicle for leaks and that the
sealing strips are in a good condi-
tion. If the sealing strips are dam-
aged, change them immediately.

12
Safety Information
1.5.2 Batteries
• Due to a change in the center of
gravity, only approved batteries may
be installed at the intended position.
• To prevent creeping currents, al-
ways keep the batteries clean and
dry and protect them from contami-
nation, e.g. from metal dust.
• Never lay any metallic objects or
tools on batteries. Risk of short cir-
cuit and deflagration!
• Ensure sufficient ventilation in the
charging area when charging the
batteries. Otherwise there is a risk of
explosion!
• The seat console must be pivoted
open during the battery charging
process to prevent the development
of explosive oxyhydrogen!
• Only use recommended chargers!
Pay attention that the insulation is
not initially damaged and not dam-
aged during the charging process.
The cable must not rub against any-
thing. Do not use the charger if the
insulation is damaged.
• Ensure there are no naked flames
nearby when handling batteries, par-
ticularly when checking the acidity.
Risk of explosion!
• Do not inhale battery gases.
• Battery acid is very corrosive; keep
away from children.
• Wear protective goggles when con-
trolling the acid level.
• In the event of acid splashing in the
eyes, rinse them with water for ap-
prox. 15 minutes and seek medical
attention immediately.

• Always observe legal regulations
and local directives when disposing
of cleaning agents, also refer to the
German Water Resources Act
(WHG).
Disposing of batteries
• Used batteries with the recycling
symbol contain reusable commodi-
ties. The heavy metals contained
represent a major risk both to peo-
ple's health and to the environment.
Never open or damage batteries.
Never touch, inhale or swallow the
content of batteries. Health hazard!
Do not allow batteries to get into the
environment. Risk of contaminating
theground and water! In accordance
with symbol with the crossed out bin,
thesebatteriesmustnot bedisposed
of in domestic waste. Return and re-
cycling of old batteries must be

Pay attention to persons in the
vicinity of the vehicle when
completing any work.
2.1 Instruction
Instructions to operators are required
before putting the vehicle into service.
Only technicians from your local autho-
rized Hako dealer are allowed to pro-
vide initial instruction on the vehicle.
The manufacturing plant will notify the
dealer immediately after delivering the
vehicle and the dealer will contact you
to arrange a date.
2.2 Initial battery charge
An initial battery charge must be per-
formed in order for it to provide an opti-
mum performance and service life. A
battery charger is available which is
specially adapted to the batteries.
Only use batteries and char-
gers recommended by us. The
full terms of warranty can only
be accepted when these units
are used.
Before starting the vehicle up
for the first time, the batteries
to be used must be fully
charged, properly, by imple-
menting the initial battery
chargeroutine. Hako assumes
no liability for damage to the
battery caused by a fault when
the battery is charged for the
first time.
The seat console must be piv-
oted open during the battery
charging process to prevent
the development of explosive
oxyhydrogen!
Only use the original charger!
Pay attention that the insula-
tion 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 in-
sulation is damaged.
Do not inhale battery gases.

Please pay attention to the operating
manual provided with the charging unit
as well as the manual from the battery
manufacturer. Powering up the batter-
ies is described in such detail in the
manufacturer's documents that further

first time
The following work must be completed
before starting the vehicle up for the
first time:
2.3.1 Installing the rotary brushes
Two rotary brushes must be fitted in the
rotary brush head. These rotary brush-
es are not part of the scope of delivery
supplied with the vehicle. Choose the
rotary brushes separately according to
the task to be completed (refer to Sec-
tion 4). If you ordered the rotary brush-
es together with the vehicle, the rotary
brushes are normally already installed
by the authorized Hako dealer prior to
delivery.
Check whether rotary brushes
are fitted.
If no rotary brushes are installed, pro-
ceed as follows to install them.
The following applies to all
work on the rotary brushes:
Turn the key switch to position
0, remove the key and apply
the parking brake (Fig. 16/8).
The front rotary brush is
changed from the right-hand
side of the vehicle, the rear ro-
tary brush from the left-hand
side of the vehicle.
