To open the ECOS Monitoring submenu, press the
monitoring submenu button (Figure 3-108) in the main
menu.
Temperature ranges and their effects:
• Above 50°F (10°C)
Normal crane operation is permissible without speed
restriction.
• From 50°F to 32°F (10°C to 0°C)
To preheat, carry out crane movements with loads only
in normal operation mode, at average engine speed and
at average operating speed.
• From 5°F to 32°F (–15°C to 0°C)
To preheat, only carry out crane movements without a
load. Only operate at normal speed, at medium engine
speed and medium working speed.
• Below 5°F (–15°C)
Crane movements are not permitted. Preheat the
hydraulic oil first.
Preheating
1. Set the swing gear to a maximum speed of 30%.
2. Lock the turntable.
3. Actuate the swing brake pedal.
4. While holding the swing brake on, attempt to swing the
boom.
5. Observe the hydraulic oil temperature; the hydraulic oil
is preheated when the display (1) (Figure 3-107) shows
a temperature of at least 50°F (10°C).
From 5°F (–15°C), you can perform crane movements
without a load in order to speed up the preheating process.
NOTE: Operate all crane functions at least twice after
preheating the hydraulic oil temperature above
50°F (10°C) in order to remove the cold oil from all
parts of the hydraulic system.

Crane Warm-up Procedures
The following procedures detail the actions that must be
taken to properly warm the different crane components
before operating the crane.
NOTE: For temperatures below -9°C (15°F) refer to arctic
lubricants and conditions in the Operator and
Service Manuals.
Before starting the crane, ensure the appropriate lubricants
are used to provide lubrication for the prevailing ambient
temperatures in which the crane will operate in (a list of
lubricants and their temperature ranges can be found in the
Lubrication section of your crane’s Operator Manual, by
contacting your local Manitowoc distributor, or by contacting
Manitowoc Crane Care directly).

CAUTION
Crane Damage Hazard!
Operating the crane with the incorrect lubricants and
fluids for the prevailing ambient temperature and/or failing
to adequately warm the crane prior to cold weather
operation can lead to a failure of a crane component or
system.
Always use Manitowoc recommended lubricants and
fluids for the prevailing ambient temperature and properly
start and warm the crane using the cold weather
procedures found in this Operator Manual and
supplement before operating the crane at full load.
