LUBRICATION AND MAINTENANCE

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 Grove
distributor or Manitowoc Crane Care if in doubt of the
suitability of a specific fluid or lubricant.
NOTE: Additional information regarding cold weather
operation is available through your Cummins
dealer/service center under Service Bulletin
3379009.
6-4
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
Section 4 - Operating Procedures to ensure adequate
lubrication during system warm-up and proper operation of
all crane functions.

Cold Weather Package and Lubricants

Grove Crane recommends the following cold weather
lubricants for use with ambient temperatures down to -29°C
(-20°F) (Table 6-2) and -40°C (-40°F) (Table 6-3). These cold
weather lubricants alone are not sufficient to operate the
crane in extreme low temperatures. Therefore, it is also
recommended that the crane be equipped with the cold
weather accessories given under the section titled Cold
Weather Operation, page 4-9.
