Operation
Button for boost function
(Fig. 19/9)
The boost function only works in combi-
nation with the Hakomatik button. The
maximum water supply and full brush
pressure are activated as long as the
Boost button remains pressed. The
icons for scrubbing (Fig. 20/10), suction
turbine operation (Fig. 20/8), solution
dosing level 6 (Fig. 20/2) and the icon
for brush pressure adjustment
(Fig. 20/11) flash in the indicator field.
After releasing the button the machine
automatically switches back to the op-
erating mode in which the machine was
running before the Boost function was
activated.
Conditions for the boost function:
• charge status of the battery is ok,
• suction turbine has not been deacti-
vated by the float switch,
• Hakomatic button is activated.
