SAFETY LOCKS 3.1 SAFETY LOCKS q If it is necessary to carry out any maintenance operation or to stop the machine with lifted loader arm, always engage the mechanical safety retainer and lock the control lever. q When travelling on roads, always engage the mechanical lock, lock the control lever in order to keep the front bucket in a stable position and use the front bucket swing lock and the teeth guard. q When travelling on roads or when the backhoe is not going to be used, always connect the boom to the safety lock, fold the arm and the bucket completely and lock both the swing and the control lever.
On machines equipped with backhoe servo controls, the movements are inhibited by the servo control locking button (see "3.3.2 pos. 12 - SERVO CONTROL LOCKING BUTTON"). q Non-compliance with these rules may cause serious damage in case of accidental lowering or rotation of the equipment. 3.1.1 FRONT LOADER LOCKS The loader arm is provided with two safety locks that have two distinct essential functions:
a) SAFETY LOCK (1) for the position of the arm when the machine is subjected to maintenance on the propeller unit and inspection of the hydraulic system equipment and of the auxiliary equipment housed in the engine compartment and in any case to the inspections and maintenance operations that must be carried out with lifted arm (A). b) SAFETY LOCK (2) for the position of the arm when the machine is travelling on roads (B).
It is important to remember that in work conditions the safety lock (1) must be positioned against the arm (C) and secured in that position by means of the safety pin (3), while the safety lock (2) must be stored in the tool box positioned in the operator's cab, inside the right access platform. IMPORTANT q The safety locks (1-2) must always adhere to the rods of the hydraulic cylinders, on whose eyes they are applied. q The safety locks must be positioned definitively by bringing the contact surfaces against each other with a slow and continuous movement, in such a way as not to damage the cylinder head surfaces.
q When the safety locks are in their definitive position, secure them with the safety pins (3). 64 DANGER
