CD5520/YB5520 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
COLD CLIMATE ENGINE OPERATION
Additional information regarding cold weather operation is
available through your Cummins dealer/service center under
Service Bulletin 3379009.
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).
Engine
Warm-up Procedures for All Temperature Ranges:
1. Upon startup, allow the engine to idle for 3 to 5 minutes
before operating with a load.
2. Cold Engine Startup: After allowing the engine to warm
by idling it for 3 to 5 minutes, slowly increase the engine
speed to provide adequate lubrication to the bearings
and to allow the oil pressure to stabilize.
Transmission
Operating the transmission with a sump temperature below
normal operating temperature is limited to:
• operating in the neutral gear or
• driving with an unloaded crane while not exceeding
1500 engine RPM and not exceeding half throttle.

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’s Manual and
supplement before operating the crane at full load.
