Instruction is required before first oper-
ation. First instruction into handling of
the machine must be held by a qualified
person sent by your local Hako contract
dealer. Your Hako dealer will be in-
formed by the manufacturer upon deliv-
ery of the machine and will contact you
to make a date for instruction.
2.2 Initial charging procedure
Before first operation of the
machine, fully charge the bat-
tery with an initial charging pro-
cedure and comply with the op-
erating instructions of the
chargeraswellaswiththoseof
the battery manufacturer.
Hako cannot be held liable for
damages resulting from an in-
sufficient initial charge.
2.3 Before Putting into Operation

tore-chargingofbatteriesifrequired.
Generally proceed to initial charging
before first operation of the machine.
5. Empty recovery tank and clean it if
required, see maintenance chapter.
6. Refill solution tank and add cleaning
agent according to the manufactur-
er's recommendations.
Use only cleaning agents suit-
able for automatic machines
(low-foaming) and comply with
theinstructions foruse, dispos-
al and with the warning infor-
mation specified by the clean-
ing agent's manufacturer.

First Operation
2.5.1 Useful tips
Before beginning wet cleaning, sweep
the floor. This not only improves the
cleaning effect but also reduces the ma-
chine's liability to wear.
The floor should be treated twice in the
case of particularly dirty floors or to re-
move wax (thorough cleaning). During
the first cleaning process, the floor is
scrubbed with a cleaning agent dosage
appropriate to the degree of soiling,
whereby the squeegee is raised.
The cleaning agent is left to act on the
floor for approx. 5 to 10 minutes accord-
ing to the manufacturer's instructions,
then scrub the floor again and, after
that, treat it with the squeegee lowered.
Important information: pay attention to
the correct dosage of the cleaning
agent. The correct dosage helps to re-
duce costs and protect the environ-
ment. The development of excessive
foam impairs the machine's function. It
indicates there is too much cleaning
agent or the wrong one has been se-
lected for the cleaning process being
completed.Unusedcomponent partsof
a cleaning agent which end up in the
waste water lead to the development of
foam. Information on dosage is provid-
edonthecleaningagentcontainer. Use
the manufacturer's information as an
initial basis. Practical experience will
ensure that you quickly find out which is
the right Hako cleaning agent and the
optimum dosage to suit your needs.
