OPERATION OF DOUBLE ACTING LEVER
When the relief valve begins to operate,
with the hydraulic cylinder lifted by the
lever, let go the lever to be in the neu-
tral position. If the relief valve is keep-
ing on operating, it leads to performance
deterioration of related parts due to over-
heating of oil.
