Spraying

surfaces. There is a risk of slipping.

gun aimed only at the pumps, valve blocks,
screw connections, pipes, hoses of the
hydraulic system of the superstructure:
– On the derricking cylinder (2)
– On the slewing gears (1)
– On the slewing duct (3)
– On the hoists (4)
• Clean surfaces sprayed by accident immedi-
ately with water.
• Let the corrosion protection dry for one hour.
• Check that a transparent waxy protective film has covered the entire sur-
face.
