MAINTENANCE (FIG.5 - FIG.6)
Main brush (Fig.5)
The main brush sweeps dust and refuse into the bin at
the rear of the motor-sweeper.
!
Caution!
Never sweep up string, wire, etc., which can become
entangled in the brush and damage the bristles. Pe-
riodically check the condition of the brush.
Adjusting the main brush (Fig.5)
The main brush should just touch the fl oor. While the
motor-sweeper is stationary on an even fl oor the section
of fl oor covered by the bristles should be 3 cm wide (see
picture). If the main brush no longer touches the fl oor, or
leaves lines of dirt, it has worn down (5 mm) and must
be lowered. Proceed as follows to lower the main brush:
• Slacken
off nut 4
•
Turn knob 5 clockwise by 1 notch (each notch cor-
responding to 2.5 mm lowering - 3 cm wide trace)
•
Re-tighten nut 4.
!
Caution!
the second notch and arrow 3 correspond to the work
position with a new main brush (3 cm trace)
Replacing the main brush (Fig.5)
•
Remove the refuse bin and lift up the motor-swe-
eper at the front.
•
Remove the two bolts 1 securing the brush to the
drive pins 2.
•
Remove the old brush and mount the new one.
