Hydraulic Oil
General
Optional thermostatically controlled heaters (120 or 240 volt)
can be installed in hydraulic tank to aid in cold-weather
startup.
Heaters are designed to keep the oil temperature 30°F
(17°C) warmer than ambient air temperature. Contact your
Manitowoc dealer for availability and installation of cold
weather heater package.
Hydraulic tank heaters must be unplugged when engine
is running to prevent hydraulic system from
overheating.

expected ambient temperature will remain at 32°F (0°C) or
below.
Change hydraulic system oil to ISO Grade 46 when the
expected ambient temperature will remain above 32°F (0°C).
