STENSBALLE / NESBO sweepers

User manual

GB

Vibration

Mechanical sweepers are equipped with a PTO shaft.

Depending on the type of tractor and front hitch system used, the 

distance between the PTO connection and the ground may vary. 

Please make sure that the tractor is suitable for the sweeper.

Please be aware that there may be situations where the two universal 

joints on the PTO shaft are not at the same angle. This will typically 

occur when the sweeper is swung to one side.

If the brushes rotate very unevenly and the sweeper makes a lot of 

noise during operation, this indicates that the PTO axle is overloaded 

due to the lack of alignment between the 2 universal joints and/or too 

sharp turns.

Contact your dealer for more information.

NOTE

Unnecessary wear on the PTO shaft

If the PTO axle instructions are not observed, the 

machine may vibrate causing unnecessary wear on 

the PTO axle and other parts.

Ejecting material

When using the hydraulic swing function, material may be ejected to 

the right or left.

Please make sure that the indicated rpm is maintained and that the 

operating speed is always controlled so that the machine sweeps the 

ground cleanly.

CAUTION

Damage to machinery or attachments

When sweeping snow or large quantities of heavy 

material, you must regulate operating speed so that 

the machine sweeps the material to one side – rather 

than pushes it ahead of the brush roll. If material 

accumulates ahead of the machine, the gears will 

overload, causing serious damage to the machine.

If rope, steel wire, etc. becomes entangled in the 

brushes, stop the machine immediately and remove 

the items.
