completely and securely supported. Secure the drill on trestles or stands and lock all lifting
rams with their yellow locking devices. See "2.26 Locking the lifting rams during service" on
page 58.
Ensure also that the surface supporting the trestles is firm enough to support them. If the hopper
is full, which it ought not to be, the weight of the drill is considerable. A full RDA 400 S around

weights greater than 3 000 and 3 500 kg respectively.
"Figure 4.4" shows the recommended placement of the trestles.
The hydraulic system must always be bled following service of the system. Make sure
NOTE!
there is nobody in the immediate work area of the machine. Operate the lifting ram, the bout mark-
er rams and the pre-implement rams to their end and inner stops a couple of times until all air has
been evacuated from the hydraulic systems
