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.
