Walk-Around Inspection
Check the machine
• Check visually upper and lower joints
of lateral inclination cylinders and
cross joint.
• Inspect the lifting point of leader
mounted device (hammer, rotary head,
vibrator etc.).
• Keep a close watch for leaks in
cylinders. If leaking is observed, find
the source and correct the leak.
• Inspect all lifting devices (winches,
steel ropes, lifting hooks and chains).
• Check that steel ropes are correctly on
winch drums and pulleys.
• Check that winches fastening bolts are
not loose, tighten if necessary.
• Checking of bolts is easiest, when
counterweight is fully out.
• Inspect the possible leaks of the
hydraulic system (cylinders, hoses,
tubes, fittings and joints). Correct the
leaks as soon as possible.
