HANDLING AND INSTALLATION Release the parking brake by pressing the lever next to the pedal. Lifting and transporting the palletized machine ! ATTENTION: during all lifting operations, make sure tipping over or being accidentally dropped. The machine must be loaded onto/unloaded from vehicles in areas with adequate lighting.
Batteries switch the machine on by turning the ignition key. ! ATTENTION: do not use NON-rechargeable batteries machines: Leak-proof tubular batteries (WET): the electrolyte level must be checked regularly. Sealed batteries (GEL or AGM): this type of battery requires no maintenance. correspond to those listed in the section on the “Technical of the machine.
! DANGER: during installation of the batteries removal of the batteries must be entrusted or any type of battery maintenance, the skilled to a TENNANT-approved service technician technician must wear the Personal Protective (referred to hereinafter as skilled technician). Equipment (gloves, eyewear, overalls, etc.) needed to limit the risk of accidents.

Unlock the dirty water tank from the solution tank Tilt the dirty water tank backwards. by pulling the knob as illustrated. ! DANGER: after tilting the dirty water tank, the safety bracket must be inserted into one of the two available slots to prevent the tank from accidentally closing.
Choosing the battery charger ! ATTENTION: check that the battery charger is compatible with the batteries being charged. Tubular lead-acid (WET) batteries: an electronic battery charger is recommended, but consult the manufacturer of the external battery charger. for the type of battery. Preparing the battery charger Connect the vacuum hose to the squeegee, bending it to the position as illustrated.
The angle of the blades can be adjusted by turning the Installation of Brush (or Drive disc) knob positioned above the squeegee. the brushes underneath the housing, making certain that they rest against the locating stops to align them with the coupling assembly. Similarly, the height of the squeegee can be adjusted by raising or lowering the two wheels positioned in front of / behind the squeegee, turning the relative knobs.
Press the brush coupling/release button, the which immediately enables the coupling operation; now the machine is ready for the coupling step, which can be accomplished by pressing the brush coupling and release button a second time. Remove the cover from the brush compartment by unscrewing the knob.
Disassembly: Repeat the steps described above in reverse order. Filling the detergent tank ! ATTENTION: before carrying out the operations apply the parking brake. ! ATTENTION: when using the Chem Dose device with WATER ONLY, at a temperature of between +4 °C / 39.2 °F and 55 °C / 131 °F.
Chem Dose – (Chem Dose model) Select the percentage dilution of the detergent – (Chem Dose model). Regulate the detergent mixture to be supplied to the liquids. brushes as follows: Turn the ignition key to switch the machine on. ! ATTENTION: before carrying out the operations apply the parking brake.

Press the ‘+’ and ‘-’ buttons to set the detergent percentage, minimum 0.5%, maximum 10%. To store the changes and exit, press and hold the programming button until the display shows the battery voltage.
PRACTICAL GUIDE FOR THE OPERATOR Clothing and equipment Wear safety shoes with non-slip soles. Wear protective eyewear or visor and safety garments. Depending on the surface being cleaned and on the envi- ronment, the protective measures necessary for atomized sprays include respiratory masks with class FFP2 or equiv- alent or higher protection.
