3.2.1.2 Check Sweeping Mark Distance
•
Take machine to level concrete or asphalt ground
(check inflation pressure of machines equipped with pneumatic tyres and correct pressure if required)
•
Switch on cylindrical broom and let it run briefly while vehicle is standing
•
Lift up and switch off the cylindrical broom, forward machine a short distance and measure dimensions of sweeping marks
With correct adjustment of the cylinder broom, the marks left on the ground have to be in parallel. The distance between parallel
sweeping marks of the Jonas 1200 E should amount to 50 + 5 mm, that of the Jonas 1200 V/D to: 70 +10 mm.
Note:
Exceeding the specified width has a negative effect on the service life of the cylindrical broom.
The distances between marks reduce as the cylinder broom diameter reduces due to bristle wearing.
3.2.1.3 Adjust Sweeping Mark Distance
Adjust the sweeping mark distance by turning the hand wheel located under the engine compartment cover. The “mark pin” indicates
wear limit of the cylindrical broom.
