GRT9165 OPERATOR MANUAL MAINTENANCE AND LUBRICATION
ARCTIC LUBRICANTS AND CONDITIONS
Arctic Conditions 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. 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 or lubricant,
check with an authorized Grove distributor or Manitowoc
Crane Care.
NOTE: All fluids and lubricants may be purchased by
contacting your local Grove distributor or
Manitowoc Crane Care.
Regardless of temperature and oil viscosity, always follow
the cold weather start-up and operating procedures, as
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 recommends specific Cold Weather lubricants for use
in ambient temperatures down to -29°C (-20°F). Refer to
Table 6-2 for a list of these recommended Cold Weather
lubricants.
Additionally, Grove recommends specific Cold Weather
lubricants for use in ambient temperatures down to
-40°C (-40°F). Refer to Table 6-3 for a list of these
recommended Cold Weather lubricants.
These recommended Cold Weather lubricants alone are not
sufficient to operate the crane in extreme low temperatures
(arctic conditions). Therefore, Grove recommends that the
crane be equipped with specific cold weather accessories,
as listed under the section Crane Warm-up Procedures,
page 4-11.
