the solution and waste water tanks contains silver ions in nanoparticle form.
• Spare parts must be original spare parts to guarantee safety.
Note
Before starting up the machine, read the following safety instructions
and act accordingly. Machine operating errors can be avoided and
trouble-free operation can be guaranteed only with precise factual
knowledge.
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, which are enclosed with each Li-Ion battery. Minuteman assumes no
liability for battery damage resulting from insufficient commissioning
charge.

During operation
• Sturdy and slip-proof shoes must be worn when working with the machine.
• Only those surfaces approved by the contractor or its DXWKRUL]HG
represent-ative for use of the machine may be cleaned.
• When working with the machine, pay special attention to third persons,
especially children.
• When driving over thresholds up to 1 cm high, pull the machine over the
threshold in transport position. For thresholds over 1 cm high, lift themachine
by the handle loop and place it over the threshold.
• Only use detergents suitable for automatic machines (foam retarded) and
observe the application, disposal and warning instructions provided by the
detergent manufacturer.
• The machine is not suitable for removing liquids, dusts or materials that are
dangerous to health, combustible or explosive. It is also prohibited to collect
burning objects, e.g. glowing cigarettes. The collection of dry wood dust,
Hg. beech and oak dust, is also prohibited – health hazard!
• The machine must not be used in potentially explosive atmospheres.
• Warning! The machine should only be used on level surfaces with
a maximum slope of 2%.
• Manipulating the switches and protective devices is forbidden.
• Daily and weekly maintenance work must be done in accordance with the

please contact your nearest Minuteman service centre.
• The maintenance work and maintenance intervals specified in the
operating manual must be complied with.
• Use suitable tools for the cleaning and maintenance work.
• Have the machine checked for safe condition by an expert in accordance
with the accident prevention regulations at appropriate intervals (we
recommend at least once yearly).
• Spare parts must at least comply with the technical requirements specified
by the manufacturer. This is guaranteed by original spare parts.
• Turn the machine off for cleaning and maintaining the machine as well as
before replacing parts.
• Cleaning the machine with a high-pressure cleaner or steam jet is not
allowed.
• Application of aggressive and corrosive detergents is not allowed.

Page 10 Scrubmaster B5 988793UM Rev A 06/23
1.5 Information about special risks
Magnets
There is a magnet in the area of the solution tank and the waste water tank.
Warning! Magnets can affect the function of pacemakers and implanted
defibrillators.
• If you have such a device, keep a minimum distance of 80 mm to the
magnet.
• Warn people with a pacemaker and implanted defibrillator not to approach
magnets.
Caution! Magnets generate a far-reaching, strong magnetic field that can
damage credit cards, debit cards, mechanical watches and hearing aids.
• Keep objects that can be damaged by strong magnetic fields away from
the magnet.
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.

Page 11
Scrubmaster B5 988793UM Rev A 06/23
Batteries
• Observe the operating manuals and safety instructions provided by the
battery manufacturer! The operating manual is enclosed with the battery.
• Only use the Minuteman charger supplied to charge the battery.
• Make sure that the batteries are never fully discharged; recharge them as
quickly as possible.
• Only instructed operating staff must handle and change batteries.
• Risk of explosion! Do not heat up the battery or place it in a fire.
• Do not drop or damage the battery.
• Caution! Always make sure that the batteries are clean and dry to avoid
creeping currents. Protect the batteries, in particular, against conductive
contamination, e.g. metal dust.
• Risk of short circuits and spark formation! Do not touch the battery
terminals with metal objects and do not insert metal objects through
openings in the battery!
• Risk of short circuit! During storage, keep the battery away from metal
objects such as paper clips, coins, nails or similar.
• If liquid escapes from the battery or there is a strange smell, remove the
battery from all heat sources or flames! There is a risk of fire or breakage
if the escaping liquid or gas ignites.
• Keep the battery out of the reach of children.
• For further safety instructions, see Minuteman supplementary sheet 88-60-
2556 – information for drive batteries.
