Hydraulic Oil Reservoir Level
The hydraulic oil reservoir has a sight gauge (1, Figure 5-6)
located on the side of the reservoir. The oil in the hydraulic
reservoir is sufficient when the level is between the High and
Low marks on the sight gauge with the crane parked on a
level surface in the transport position and the oil cold.
If the oil level is too low, add the recommended hydraulic oil
until the oil level is even with the upper mark. If the oil level is
high, drain oil until the oil level is even with the upper mark.
Surface Protection for Cylinder Rods
Steel cylinder rods include a thin layer of chrome plating on
their surfaces to protect them from corroding. However,
chrome plating inherently has cracks in its structure which
can allow moisture to corrode the underlying steel. At typical
ambient temperatures, hydraulic oil is too thick to penetrate
these cracks. Normal machine operating temperatures will
allow hydraulic oil to warm sufficiently to penetrate these
cracks and if machines are operated daily, protect the rods.
Machines that are stored, transported, or used in a corrosive
environment (high moisture, rain, snow, or coastline
conditions) need to have the exposed rods protected more
frequently by applying a protectant. Unless the machine is
operated daily, exposed rod surfaces will corrode. Some
cylinders will have rods exposed even when completely
retracted. Assume all cylinders have exposed rods, as
corrosion on the end of the rod can ruin the cylinder.
It is recommended that all exposed cylinder rods be
protected using Boeshield
®
T-9 Premium Metal Protectant.
Manitowoc Crane Care has Boeshield T-9 Premium Metal
Protectant available in 12 oz. cans that can be ordered
through the Parts Department.
NOTE: Cylinder operation and inclement weather will
remove the Boeshield protectant. Inspect
machines once a week and reapply Boeshield to
unprotected rods.
