5.1 - VERIFICATIONS
• Ensure that the hydraulic connections are properly tight and that the hydraulic system operates correctly:
- purge of circuits,
- valve position,
- hydraulic pressure (1.5 to 3 bar).
• No leaks.
• Proper machine stability.
• Electrical cables and wires are well secured to their connection terminals. Loose terminals can cause heat build-up on the
terminal board and malfunctions.
• Ensure that the electric cables are properly protected from all sheet metal edges or metal parts that could damage them.
• Ensure that control cables and power cables are properly separated.
• Check that the unit is properly grounded.
