BACKHOE ATTACHMENT OPERATING INSTRUCTIONS Template Name: OM_1_col Template Date: 1994_04_29
The instructions contained in this chapter do not cover all possible conditions of operation for the backhoe attachment. They only constitute basic information to enable the machine to be operated correctly. NOTE : The first time it is operated, manoeuvre the machine in a clear area, at low speed. NOTE : For the operation of the controls, see "Backhoe attachment controls" in the "Controls/Instruments/Accessories" section.
Safety instructions - Be careful. - Make sure that the operator’s seat is correctly adjusted in the backhoe attachment position. - Use the seat belt.

- Make sure that no other person is in the working range of the machine. - Place the attachment in the working position. See “Setting the machine in the backhoe attachment working position” in the “Operating instructions” section. - Never dig near or under the stabilizers, since the machine could fall into the excavation.

- When working in an area of reduced visibility, for example next to a building, place a safety barrier and sign panels to prevent anyone coming near the machine.
General The backhoe attachment will dig more quickly if the work cycle is short and uninterrupted. Organize your work site so as to obtain a smooth work cycle. If you try to take a very big cut with the backhoe bucket, you may cause a hydraulic stall situation (where the dipper control lever is pulled towards the operator but nothing happens). The hydraulic system main relief valve makes a noise when a hydraulic stall occurs. This overload causes the work cycle to be prolonged and it increases the hydraulic temperature.
