1300A OPERATOR’S MANUAL LUBRICATION PROCEDURE AND CHARTS
SECTION 5
LUBRICATION PROCEDURE AND CHARTS
GENERAL
Following the designated lubrication procedure is important
in ensuring maximum crane lifetime and utilization. The
procedures and lubrication charts in this section include
information on the types of lubricants used, the location of
the lubrication points, the frequency of lubrication, and other
information. The information included in this section does not
include lubrication requirements for the truck chassis. Refer
to appropriate truck manufacturer's manual for this
information.
The service intervals specified are for normal operation
where moderate temperature, humidity, and atmospheric
conditions prevail. In areas of extreme conditions, the
service periods and lubrication specifications should be
altered to meet existing conditions. For information on
extreme condition lubrication, contact your local National
Crane Distributor or Manitowoc Crane Care.
Arctic Conditions Below -18°C (0°F)
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. If you are in doubt about the
suitability of a specific fluid, check with your authorized
Manitowoc distributor or Manitowoc Crane Care.
NOTE: All fluids and lubricants may be purchased by
contacting the Manitowoc Crane Care Parts
Department.
Regardless of temperature and oil viscosity, always use
suitable start-up procedures to ensure adequate lubrication
during system warm-up.
Chassis Grease
Lubricating grease of proper consistency is to be applied
periodically at relatively frequent intervals with grease guns
through grease fittings. Minimum apparent viscosity of 300
SUS (Saybolt Universal Seconds) at 100° F (38° C) is
recommended.
Extreme Pressure Multipurpose Gear
Lubricant
This gear lubricant is compounded to achieve high load
carrying capacity and meet the requirements of either API-
GL-5 or MIL-L-2105C. Unless otherwise specified,
SAE 80W-90 viscosity may be used for year round service.
Low temperature usage is restricted as follows:
Open Gear Lubricant
This is a special high-graphite adhesive lubricant that helps
to eliminate fretting corrosion, is water resistant, and forms a
dry lubrication film which does not attract dust. Lubricant
meets NLGI Class 1-2 specifications.
Anti-wear Additives
Excessive wear in the system may cause a loss in volumetric
efficiency, and may cause shutdowns for maintenance. An
efficient anti-wear oil protects the components against
rusting, resists oxidation and helps prevent wear.
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
CAUTION
Do not use air pressure devices to apply chassis grease
otherwise damage to sealed fittings may result.
CAUTION
The multipurpose grease installed during manufacture is
of a lithium base. Use of a noncompatible grease could
result in damage to equipment.
