Near the Ocean After Operation : The following salt pollution measures must be taken when the machine is
operated at sea or near the coastline.
(1) After completing the work, extend/retract the hydraulic cylinders
several times to form an oil film on the rod surface. Store the machine
with cylinders retracted as much as possible.
(2) Thoroughly clean the machine with fresh water to wash off salt.
(3) To prevent corrosion, perform touch up painting periodically on hose
fittings, lubrication piping and inserting position of cover, where sea
water is easily collected.
(4) During storage of the machine, cover the machine with tarpaulin
to prevent sea water from entering into the cab vent. Apply rust
prevention oil (example: ANTIRUST P-1300NP-3 JX Nippon Oil &
Energy Corporation) onto plated part of the cylinder rods.
