A squeegee and suitable brushes or pads are required for wet
cleaning of hard floorings. The rotating brushes (1) scrubs the
floor thoroughly, removing dirt, by cleaning agent supplied from
the fresh water tank (2) thereby cleaning the floor. The soiled
water is drawn during the same cycle through the squeegee (3)
and fed into the dirty water tank (4). Thus, the floor can be
accessible immediately after it is dry and clean.
·Detergent particles contained in the soiled water that
are not used will cause formation of foam.
·Instructions for dosage are given on the detergent
container and must ideally adhere to manufacturer's
recommendations.
·The ideal type of detergent and the perfect dosage
applicable to it will come through sustained use of the
machine.
·Prior to wet cleaning, it is necessary to clean the floor. This
way, not only is the cleaning efficiency improved, but wear of
the brush is also substantially reduced.
·If floors are particularly dirty or if wax has to be removed
(basic cleaning); the floor must be treated twice.
·During the first cycle, the floor is scrubbed with the cleaning
agent selected according to the degree of dirt encountered,
the squeegee remaining lifted.
·Allow the cleaning agent to act on the floor for approx. 5 or 10
minutes, complying with the manufacturer's instructions.
·Scrub the floor once again while the squeegee is lowered.
·Too much foam indicates excessive dosage or improper
suitability of detergent for the existing kind of dirt.
Comply with instructions for correct dosage of
detergent. Correct dosage will help optimize costs
and also minimize impact on the environment. Too
much foam can affect the performance of the
machine.

voltage accordingly
Replace the coding plugs by pressing the ends together
with pliers.
All battery plugs at machines, batteries and battery
charger units have to be coded with the colored coding
pins according to the battery type and the charger unit
plugs are/will be seteristic curve such that a modification
of the curve (in relation to the battery type) requires
changing of the plug coding nominal voltage.

p l u g o n l y w i t h t h e s a m e n o m i n a l v o l t a g e .
The following three conditions have to be met:
1) Voltage coding must be the same for all sockets and
plugs.
2) Coding pin colour in the machine = yellow
3) Coding pin colour in the charger unit = the same as for
the battery plug according to battery type.
Before first operation of the machine, fully charge the
battery with an initial charging procedure and comply
with the operating instructions of the charger
as well as with those of the battery manufacturer. Roots
cannot be held liable for damages resulting from the fact
that the initial charging has not or insufficiently been
done.

Charging procedure for traction block batteries
- Drain both the tanks
- Move machine near charger location
- Switch Off Key
- Remove key
- Tilt operator seat forward completely
- Disconnect the battery plugs and connect them to the
charger supplied with the machine.
- Make sure to connect the charger to the
specified voltage and frequency.
- Ensure that the seat cover is completely open.
- Do not place any objects on the battery.
Charge the batteries in a well ventilated area.
Do not tamper with the charger settings.

Safety symbols for traction battery system
-Observe the instruction which
must be mounted clearly at the
charging point!
-No Smoking!
-No naked lights, embers or sparks
in the vicinity, risk of fire and explosion!
- Risk of fire explosion, avoid short circuits!
- Caution! Metal components in the battery
cells are always under voltage, never
place any foreign items or tools on the
battery!
-Wear protective goggles and protective
clothing when working on the batteries!
-Do not tilt the battery!
-Only use certified hoisting and
transport equipment.
-Do not throw in garbage!
-Keep children away from batteries
-Charge in a well-ventilated area
-Electrolyte is highly corrosive!
-Any splashes of acid in the eyes or
on the skin must be rinsed throughly
with plenty of clear pure water.
-Then consult a doctor immediately!
Traction Batteries (LA)
The above instructions have been
established for your safety and
have to be strictly observed.
1. Initial Checking-
Check the battery to ensure that it is in perfect mechanical
condition. All screwed unions within the circuit must be tightened
to ensure reliable contacts. Machine cables and charging cable
are to be connected to the correct poles of the battery otherwise
battery and charger can be damaged.
2. Discharging-
Ventilation openings may not be covered or closed. Electric
connections (e.g-plugs) may be connected or disconnected only
when the machine is in off condition. Discharge batteries must be
recharged immediately and may not remain in discharged
condition. This also applies to only partially discharged batteries.
The battery may only be connected up to the allocated battery
charger certified for the particular battery size, to avoid overload
on the electric current Maintenance Free Batteries have low
gassing properties but are not completely free of gassing. The
battery is to be connected with the correct poles (plus to plus and
minus to minus) to the disconnected battery charger. The battery
charger should then be switched on.
During the recharging procedure, the temperature in the
battery increases by approx. 10 °C. For this reason, the
recharging procedure may not be started unless the
temperature is below 35 °C.
Before recharging the battery, the temperature should be at
least 15 °C, otherwise the battery will not be correctly.
If the temperatures are constantly greater than 40 °C or
lower than 15 °C, temperature-dependent constant voltage
regulation of the battery charger will be necessary.
3. Temperature-
The battery temperature of 30 °C is rated temperature.
Higher temperatures shorten the service life and lower
temperatures reduce available capacity. 45 °C (51 °C for
AGM) is the limit temperature and is not tolerable as
operating temperature.
4. Electrolyte-
The electrolyte is sulphuric acid. The density of the
electrolyte cannot be measured. Use the recommended
electrolyte to top up.
5. Maintenance-
Daily maintenance- Recharge the battery every time it has
been discharged.
Weekly maintenance- Visual inspection after recharging for
signs of dirt and mechanical damage.
Maintenance to be carried out every three months
After fully recharging and following a standing period of at
least 5 hours, the following must be measured and
Recorded: – total voltage / – individual voltage
If noticeable changes are detected compared to previous
measurements, or differences between the cells or block
batteries, the customer service should be called for testing
or repair.
6. Care-
The battery must be kept clean and dry to prevent creeping
current. Any liquid in the battery container must be
extracted and disposed of according to regulations.
