The TTB 3226 has been fitted with a Hi - Lo function, this reduces the noise produced by
the vacuum motor by 3dB.
To operate the Hi - Lo mode start the machine in the normal way.
When the machine is running normally the Hi - Lo light will be illuminated Blue
This means the Vacuum motor is running at 100%.
With the machine running press the Hi - Lo button once the Vacuum motor will reduce
speed to 75% of capacity and the Hi - Lo light will NOT illuminate Blue.
Use the maximum speed control knob and set desired
traction speed as required, depending on floor type and
level of soiling.
Middle speed is the optimum cleaning speed for most types
of floors.
Once the Max speed has been set using the control knob on
the control panel, fine adjustments can be made using the
variable control speed pedal located on the right side of the
footplate.
