tank (D) with asolution suitable for the work to be performed.
Refill to the reference mark “1” of the level check hose (H).
Always follow the dilution instructions on the label of the
chemical product used to prepare the solution.
The solution temperature must not exceed +104°F (+40°C).
WARNING!
Use only low-foam and non-flammable detergents,
intended for automatic scrubber applications.
3)
( For machines with Chemical Mixing System)
Fill the tank (D) with clean water by using the filler neck (B)
or the rear filler neck (C).
Refill to the reference mark “1” of the level check hose (H).
The water temperature must not exceed +104°F (+40°C).

Open the cover (E) and check that the recovery water tank
(F) is empty, otherwise empty it with the drain hose (G).
Carefully lift the tank (A, Fig. 15).
Open the cap (B).
Replace or fill the jug (C) with any standard gallon container
of detergent suitable for the work to be performed (highly
concentrated detergents).
Do not fill the detergent tank completely, leave afew
centimeters from the edge.
WARNING!
Use only low-foam and non-flammable detergents,
intended for automatic scrubber applications.
NOTE
To install anew jug container, determine the cap size and
if it is the smaller cap, remove the reducing adapter from
the hose cap (B). Insert the suction tube into the jug (C).
Pushdown firmly on the cap (B) and twist at the same
time to put the cap back onto the jug (C).

·By pushing it with the hands on the handlebar (E) and
pressing the switch (F) to move forward, or pressing the
switch (F) together with the switch (G) to move backward
(only for FOCUS II L17, FOCUS II L20, FOCUS II L20
Cyl., BOOST L20 ).
The forward speed can be adjusted with the adjuster (H).
Lower the squeegee (I) with the lever (J).
Lower the brush/pad-holder deck (K) by pressing the pedal
(L).
Press the brush/pad-holder switch (M) and the vacuum
system switch (N).
Press the washing water flow control switches (O) as
necessary, depending on the type of cleaning to be
performed.
Start cleaning:
·(Only for FOCUS II S20 )by pushing the machine with the
hands on the handlebar (E) and pressing the switch (F).
·(Only for FOCUS II L17, FOCUS II L20, FOCUS II L20
Cyl., BOOST L20 )by pushing the machine with the
hands on the handlebar (E) and by pressing the switch
(F). If necessary, the forward speed can be adjusted with
the adjuster (H).
NOTE
To move the machine forward, press either the left or
right switch (F) or both.

Stop the machine by releasing the switches (F) (Only for
FOCUS II L17, FOCUS II L20, FOCUS II L20 Cyl., BOOST
L20 ).
Stop the brushes and the vacuum system by pressing the
switch (M). The vacuum system stops after afew seconds.
Lift the brush/pad-holder deck (K) by pressing the pedal (L).

MACHINE OPERATION (SCRUBBING/DRYING)
1.
2.
3.
Start the machine as shown in the previous paragraph.
If necessary, press the washing water flow control switches
(A and B, Fig. 17) as necessary, depending on the type of
cleaning to be performed.
If necessary, stop the machine and adjust the squeegee
with the knob (C) so that the rear blade (D) touches the floor
along all its length.
Machine drive controls
CAUTION!
These procedures must be performed by qualified
personnel or Clarke personnel only.
The machine speed and forward movement capability depends on
the floor type and on the choice of using brush or pad.
These can be adjusted by two screws (B and D, Fig.18), which
are on the brush plate, according to the following procedure:
– Loosen the nut (A); when turning the adjusting screw (B)
counter-clockwise, the machine moves towards the left;
when turning it clockwise the machine moves towards the
right.
– (Only for FOCUS II S20 )loosen the nut (C); when turning the
adjusting screw (D) counter-clockwise, the machine speed
increases; when turning it clockwise the machine speed
decreases.
When the procedure is completed, tighten the nuts (A and/or C).

NOTE
For correct scrubbing/drying of floors at the sides of the
walls, Clarke suggests to go near the walls with the right
side of the machine (A and B, Fig. 19) as shown in the
figure.
CAUTION!
To avoid any damage to the floor surface, turn off the
brushes/pad-holders when the machine stops in one
place, especially when the extra pressure function is
on.
Detergent flow adjustment
(For machines with Chemical Mixing System)
1)
2)
3)
Turn the knob (A, Fig. 20) clockwise or counter-clockwise to
increase or decrease the detergent concentration.
The average detergent concentration values, matching the 4
colored areas of the scale (B), are shown in the figure.
To set the detergent quantity to zero, fully turn the knob (A)
counter-clockwise.
Figure 19
NOTE
The detergent concentration is kept constant even if the
washing water flow is changed with the switches (C) or
(D).
Working with brush/pad-holder extra pressure function
turned on
If the floor proves to be particularly difficult to clean, it is
possible to turn on the brush/pad-holder extra pressure
function by pressing the pedal (E) to position (E3).
CAUTION!
When the cylindrical brush deck (S, Fig. 2 - Page 9) is
installed, the extra pressure function is not enabled.

Battery discharge during operation
Until the green warning light (A, Fig. 21) stays on, the
batteries allow the machine to work normally.
When the green warning light (A) turns off, and the yellow
warning light (B) turns on, it is advisable to charge the
batteries, because the remaining charge will last for afew
minutes (depending on battery characteristics and work to be
performed).
When the red warning light (C) turns on, batteries are fully
discharged. After afew seconds, the brush/pad-holder is
automatically tuned off, while the vacuum system and (only
for FOCUS II L17, FOCUS II L20, FOCUS II L20 Cyl.,
BOOST L20 )the drive system stay on, to finish drying the
floor and drive the machine to the appointed recharging area.
CAUTION!
Do not use the machine with discharged batteries,
to avoid damaging the batteries and reducing the
battery life.
TANK EMPTYING
An automatic float shut-off system (A, Fig. 22) stops the vacuum
system when the recovery water tank (B) is full.
The vacuum system deactivation is signaled by asudden
increase in the vacuum system motor noise frequency, also the
floor has not dried.
CAUTION!
If the vacuum system turns off accidentally (for
example, when the float is activated because of
a sudden machine movement), to resume the
operation: turn off the vacuum system by pressing
the switch (D, Fig. 19), then open the cover (C, Fig.
22) and check that the float inside the grid (A) has
gone down to the water level. Then close the cover
(C) and turn on the vacuum system by pressing the
switch (D, Fig. 19).
When the recovery water tank (B, Fig. 21) is full, empty it
according to the following procedure.
