Dual Sweep Machines
1.
Adjust the Top Link and/or Motor Bracket of each brush, until about
40
% or
150
° of its circumference, at the outer/leading edge, is in
contact with the road surface.
CAUTION:
An incorrect front brush set-up affects not only sweeping efficiency, but
can also greatly influence the rate of brush wear.
REMOVING / REFITTING THE BRUSH HEADS
The Scarab Minor Euro 3 is fitted
with quick-release brush hubs.
These hubs incorporate slotted
holes. Brush removal is
accomplished by loosening the
four flange nuts and rotating the
brush, until the nuts align with the
holes. The brush can then be
taken off and/or refitted without
removing the nuts from the brush
bolts. All Scarab supplied
replacement brushes now have
captive bolts and are supplied
with new flange nuts.
CAUTION:
Care should be taken to ensure that when fitting/refitting brushes they
are correctly positioned on the hubs, in accordance with the illustrated
alignments (see Fig. 7).
FLUID LEVELS
For coolant and hydraulic filler points refer to Fig. 8.
The brake and screen-wash reservoirs are in the cab. Access to the brake
fluid reservoir is gained via a flap on top of the dash panel.
For engine oil filler and dipstick refer to Fig. 9.
