If you have an uneven suction result, the settings of the suction nozzle should be
corrected:Proceed as follows::
Before carrying out the settings, check that:
• the slats are not damaged (replace).
• the suction nozzle is not damaged.
Height setting(Fig. A)
• Unlock the squeegee lowering lever and push it forward.
• Pull out the key and operate the parking brake (See ‚Parking brake‘ Page 9).
• Unscrew the hexagonal nut.
• Turn the Allen screw left or right.
The distance between the floor and the running wheel (with slats perpendicular to the
floor) must be between 1 - 3 mm.
• Retighten the hexagonal nut.
• Check the result during the cleaning and refer to "Angle of inclination (Fig. B)"
if the result is unsatisfactory.
Angle of inclination(FIg. B)
• Switch off the brush drive and the suction unit.
• Pull out the key and operate the parking brake (see Parking brake‘ Page 9).
• Unscrew the Allen screw Nos. 1 to 4 on the suction nozzle adjustment (half a
turn).
• Insert a screw driver into the slot in the cam and hold it in its current position
while unscrewing the Allen screw No. 5.
• Only change the angle of inclination in small steps using the cam.
• Keep the screwdriver in this position while tightening the cylindrical screws
numbers 1 to 5.
• Check the result and correct it again if necessary.
A correct setting has been achieved if the atripper edge of
the rear slat (x) is distributed over the complete width“ of
the suction nozzle..
