2.3.3 Adjusting brush roller
• Adjust brush pressure with
handwheel. Adjustment can
be checked on scale next to
right-hand wheel. First follow
our recommendations and
then adapt brush pressure to
wear of brush roller or, if
necessary, to your local
conditions.
NOTE!
Excessively high roller pressure
increases brush wear and
requires greater pushing force.
2.3.4 Functional check
• Push the machine at normal
walking speed over the
surface to be cleaned:
The cleaning capacity is
dependent on the working speed
(number of revolutions of
the brush roller).
The side brush allows edges and
corners to be swept clean.
• Check the sweeping result
and then correct the brush
pressure if necessary.
2.4
Supervision of
operation
CAUTION!
String, wire, packing tape
and similar long objects
should be picked up from
the floor by hand and not
swept up with the sweeping
machine:
This will help to maintain the
sweeping capacity of the
machine and prevent machine
damage caused by jamming of
the drive.
Empty the dirt collecting tank at
regular intervals. Sweeping is no
longer possible when the tank is
full.
2.5
After completing work
• Empty the dirt collecting tank.
To transport or for space-saving
storage:
• Swivel up side brush arm
• Loosen wing nuts on handle,
spread handle apart
somewhat and swivel
forward.
