7.1.
Using the rotary broom
1.
Make sure that the attachment and the base machine are compatible in terms of mechanical solutions,
hydraulics and electricity.
2.
Apply parking brake. The rotary broom is attached to the coupler on the base machine (e.g. a loader). Attach
the rotary broom to the base machine, and make sure the locking cotters are secured.
3.
Turn off the base machine and make sure the parking brake is applied.
4.
Make sure there is no pressure in the base machine hydraulic system. When connecting, always make sure the
hydraulic connectors are clean and the hoses are intact.
5.
Check c
arefully the attachment’s, the base machine’s and the fitting’s trajectory for collision. Make sure that the
needed space for hydraulic hoses and -attachments is adequate. Check that the brush roll rotates outwards
from the. If not, switch hoses in the base machine.
6.
Lift rotary brooms front and back support legs. Lock them in upward position with locking cotters.
7.
Start the broom while bristles are not toughing ground, do not press bristles to ground.
8.
Keep the rotary broom in suitable distance from ground (picture 3). Brush ring should bend approx. 20mm. Do
not press the broom too hard with a base machine. Brush rings wear down faster and
the
attachment could
be damaged!
9.
Stop sweeper completely before changing rotating direction,
otherwise hydraulic motor might be damaged!
10.
Stay alert for any abnormal behaviour and oil leaks also during driving.
