WARNING
Read this manual before operating the machine
Most accidents occurring during work are due to non-observance of simple safety norms and elementary
precautions.
Many accidents can be avoided if the causes are known and opportune cautions taken beforehand.
There is no device or protection, no matter how advanced, that may prove so effective at avoiding accidents
as a careful and attentive behaviour.
WARNING
Ensure that the attachment is safely resting onto the ground before repairing, adjusting or servicing machines
fitted with hydraulically, mechanically or cable controlled attachments (such as, excavators, loaders, dozers,
scrapers, etc.). Should it be necessary to partially or fully raise the hydraulically, mechanically or cable
controlled attachment to gain access to certain items, make sure the attachment is adequately retained in the
raised position by means other than the hydraulic lift cylinders, cables and/or mechanical devices used for
controlling it.
