Arctic Lubricants and Conditions
Temperatures Below -9°C (15°F)
Regions with ambient temperatures below -9°C (15°F) are
considered arctic. In general, petroleum based fluids
developed especially for low temperature service may be
used with satisfactory results in these temperatures.
However, certain fluids, such as halogenated hydrocarbons,
nitro hydrocarbons, and phosphate ester hydraulic fluids,
may not be compatible with hydraulic system seals and wear
bands. Therefore, always check with an authorized National
Crane distributor or Manitowoc Crane Care if in doubt of the
suitability of a specific fluid or lubricant.
When operating in cold weather and regardless of the oil
viscosity of the crane’s lubricants, always follow the cold
weather start-up and operating procedures described in the
Operator Manual to ensure adequate lubrication during
system warm-up and proper operation of all crane functions.
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 (EPGL)
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.
Low Temperature Grease
This special grease for low temperature remains plastic at
-51° C (-60° F) with melting point of 138°C (280°F). The
grease is a heavy duty extreme pressure type lubricant
(Lubricate Low Temp or equal).
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.
Hydraulic Oil
Oil in a hydraulic system serves as the power transmission
medium, system lubricant and coolant. Selection of the
proper oil is essential to ensure satisfactory system
performance and life. The most important factors in selecting
an oil for hydraulic service are viscosity and anti-wear
additives.
NOTE: When operating the crane in temperatures
-9°C
(15°F)
and below, follow the procedures in the
section titled “Arctic Lubricants and Conditions” on
page 5-2.
Standard Hydraulic Oil
Temperature Above -9°C (15°F)
The factory fill standard hydraulic oil is ISO grade 46/68
Hydraulic Oil. This fluid is acceptable for operating
temperatures above
-9°C (15°F). For alternate hydraulic oil
products, refer to National Crane lube specifications.
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 non-compatible grease could
result in damage to equipment.

CAUTION
Operation of the crane with incorrect hydraulic oil in sub

damage to the extend cylinder.
