face.
2. Load is within manufacturers rated design capacity.
3. All machine systems are functioning properly.
4. Machine is as originally equipped from JLG.

called FORWARD and BACKWARD stability. The machine’s
position of least FORWARD stability is shown in Figure 4-1.,
and its position of least BACKWARD stability is shown in Fig-
ure 4-2. and Figure 4-3.
