1400A OPERATOR’S MANUAL LUBRICATION
Intermediate Hydraulic Oil
(-10°F to 80°F) (-23°C to 27°C)
For colder operating environments, the standard fluid may be
replaced with a Low Service Temperature Multi Viscosity
Hydraulic Oil with High Viscosity index 175+.
Wide Range Intermediate Hydraulic Oil.
(-30°F to 80°F) (-34°C to 27°C)
For even colder operating conditions, the standard fluid may
be replaced with a petroleum based fluid developed
especially for colder environments.
Arctic Hydraulic Oil.
(-10°F and below) (-23°C and below)
In general, petroleum based fluids developed especially for
low temperature service may be used with satisfactory
results. However, certain fluids, such as halogenated
hydrocarbons, nitro hydrocarbons and phosphate ester
hydraulic fluids might not be compatible with hydraulic
system seals and wear bands. Arctic hydraulic oil is not
recommended for service in ambient temperatures above
32°F (0°C).
If you are in doubt about the suitability of a specific fluid,
check with your authorized National Crane distributor or
Manitowoc Crane Care.
NOTE: All fluids and lubricants may be purchased by
contacting the Manitowoc Crane Care Parts
Department.
LUBRICATION POINTS
A regular frequency of lubrication must be established based
on component operating time. The most efficient method of
keeping track of lube requirements is to maintain a job log of
crane usage.
All oil levels are to be checked with the crane parked on a
level surface in transport position, and while the oil is cold,
unless otherwise specified. On plug type check points, the oil
levels are to be at the bottom edge of the fill port.
Over lubrication of non-sealed fittings will not harm the
fittings or components, but under lubrication shortens
lifetime.
Worn grease fittings that do not hold a grease gun, or those
that have a stuck check ball, must be replaced.
When wear pads or rotation bearings are lubricated, cycle
the components and lubricate again to ensure complete
lubrication of the entire wear area.
CAUTION
Operation of the crane with incorrect hydraulic oil in sub
freezing temperature (below 32°F, 0°C) can cause
damage to the extend cylinder.
CAUTION
Lubrication intervals (page 5-3) are to be used only as a
guide. Actual intervals should be formulated by the
operator to correspond accordingly to conditions such as
continuous duty cycles and/or hazardous environments.
