Transmission Operation At Low Ambient Temperatures - New Holland Boomer 45 Operator's Manual

Transmission operation at low ambient temperatures

Warm up period
WARNING
Unexpected movement!
During the warm-up operation, do the following: Engage the parking brake, set all shift levers to their
NEUTRAL positions, and place the Power Take-Off (PTO) clutch lever in the OFF position.
Failure to comply could result in death or serious injury.
The tractor hydraulic oil also serves as the tractor transmission fluid. During cold weather operation, the hydraulic
oil viscosity increases. This increase in oil viscosity restricts the oil's ability to flow and lubricate in the transmission
and hydraulic circuits. The cold oil can result in abnormal noises and slower operation times due to the increased oil
viscosity.
NOTE: A warm up time at 50% rated engine speed is recommended to assure proper vehicle functionality, transmis-
sion lubrication and operation.
NOTE: Do not operate the tractor under full load condition until the hydraulic oil is sufficiently warmed up.
