DYMET

Electric wires in touch with the excavator piston-rod create electric arc.

Electric arc caused multiple defects at the piston-rod. After the surface grinding the excavator works, but small oil leak still exists and oil becomes dirty very quickly.

Use DYMET to eliminate the defects. Blast by abrasive. Remove chromium at the defect edges.

Spray K-01-11.

Now grind again.
