Intended use
The Scrubmaster B25 is a scrubber-drier for the wet cleaning of hard indoor
floor surfaces. This machine is intended for commercial use, e.g. in shopping
centres, swimming pools, shops, airports, schools and hotels. Any use
extending beyond this is not intended use. The manufacturer is not liable for
any damage resulting from this and the user alone bears the risk. Intended use
also includes compliance with the operating, maintenance and servicing
conditions specified by the manufacturer.
The Scrubmaster B25 may be used, maintained and repaired only by persons
who are familiar with this work and instructed about the dangers.
The relevant accident prevention regulations as well as the other generally
recognised safety engineering and occupational medical rules must be com-
plied with.
The machine corresponds by virtue of its design and construction as well as in
the version distributed by us to the usual health and safety requirements of the
EC Directives (see Declaration of Conformity). This declaration loses its validity
in the event of a modification to the machine not authorised by us. The manu-
facturer is not deemed liable for any damage resulting from unauthorised
modifications to the machine.
Notes on warranty
The terms defined in the purchase agreement apply. Claims for compensation
in relation to damage are excluded from the terms of the warranty when the
damage is the result of the failure to observe rules concerning servicing and
maintenance. Maintenance work must be carried out by an authorised Hako
service workshop and confirmed in the “Maintenance Report”, which serves as
a warranty logbook.
The following are excluded from the terms of warranty: wear and tear through
overuse, defective fuses, improper handling and use and unauthorised modifi-
cations. Claims under the terms of the warranty are also annulled when dam-
age occurs to the machine resulting from the use of parts or accessories not
explicitly approved of by us or from failure to observe maintenance rules.

Before putting into service
• Before initially starting up the machine, charge the used battery fully and
appropriately with commissioning charge. Please observe the operating
manual of the charger and the operating manual of the battery manufac-
turer. Hako assumes no liability for battery damage resulting from insuffi-
cient commissioning charge.
• Check the machine for operating safety before every start-up! Eliminate
faults immediately.
• Before starting work, operators must familiarise themselves with all
equipment, operating and actuating elements as well as with their function!

Safety instructions
1.5 Information about special risks
Electrical system
• If the electrical system is faulty, always turn off the machine and eliminate
the fault.
• Work on the electrical system may be done only in accordance with
electrical engineering standards by a specialist trained for this work.
• Regularly inspect/check the electrical system of the machine. Defects such
as loose connections, loose nuts of electrified bolts, electrical components
or damaged cables must be eliminated immediately.
• Only use original fuses with the specified current. If stronger fuses are
used, the electrical system can be destroyed and there can be fires.
Batteries
• Observe the operating manuals and safety instructions provided by the
battery manufacturer.
• Never connect or disconnect batteries when the machine is turned on.
• Make sure that the batteries are never fully discharged; recharge them as
quickly as possible.
• Only instructed maintenance personnel must handle and replace batteries.
• Only batteries approved by Hako may be used at the intended position.
• Danger! Make sure that the insulation of the battery cables is not damaged.
The battery cables should not rub against anything. If the insulation is
defective, no longer use the machine and have the battery cables replaced
by the Hako customer service immediately.
• Caution! Always make sure that the batteries are clean and dry to avoid
creeping currents and corrosion damage. Protect the batteries, in
particular, against conductive contamination, e.g. metal dust.
• Risk of short circuits and spark formation! Never place tools or other
electrically conductive objects on the battery!
• Do not remove insulating caps and covers, if necessary re-install them after
carrying out work on the battery cables.
• Caution! Explosive gases can develop when charging the batteries.
Avoid smoking, fire or naked light in the vicinity of batteries. Ensure
sufficient ventilation when charging the batteries.
• For further safety instructions, see Hako supplementary sheet
88-60-2556 – information for drive batteries.

carry out recommissioning.
• Check the mains cable regularly for damage. If damage is detected, the
machine must no longer be used. Have a qualified electrician replace the
mains cable.
• Make sure that no water or liquid can come into contact with live parts of
the machine. If water has still entered parts, immediately disconnect the
mains plug and have the machine checked by the authorised Hako
service.
