-
All functions are in order
-
Learn the functions of the back broom in an enclosed area before actual usage.
7.1.
Using the back broom
1.
Make sure that the attachment and the base machine are compatible in terms of mechanical solutions,
hydraulics and electricity.
2.
The back broom is attached to the coupler on the base machine. Reverse the base machine near the broom.
Attach the support beams to the broom. Attach the back 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.
Lift back brooms front support legs. Lock them in upward position with locking cotters.
6.
Check carefully 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.
7.
Keep the back 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!
8.
The maximum rotational speed of the broom roller is 300 r/min. Gear ratio for the broom roller us 1:1,4
(retardant). Adjust the power out-
take (540 r/min) and the engine’s rotational speed
so that the max. rotational
speed of the broom roller is not exceeded.
9.
Adjust the driving speed and the rotational speed of the broom appropriate for the amount of sand / trash.
10.
Back brooms horizontal propeller shafts are equipped with overload switch. Their max. torque is 900 Nm. It is
forbidden to replace to overload switch with a stronger torque switch.
11.
Stay alert for any abnormal behaviour and oil leaks also during driving.
