Can the oil injector and auxiliary oil pump be turned off when cranking a reciprocating compressor regularly?

Or can only the auxiliary oil pump be turned off, while the oil filler must remain on?
Before, during, and after shaft turning, the auxiliary oil pump must be turned on to prevent dry rubbing of the bearing shells, crossheads, etc., which could cause damage to them.
Starting first is correct. Auxiliary equipment. Then stop the parking brake. Power on to start operation
First, turn on the auxiliary facilities and the oil injector, then perform shaft turning
First, it is necessary to understand the functions of the two types of oil: the circulating oil is used to lubricate the bearings and bearing shells, while the oil injector is used to lubricate the moving parts inside the cylinder. Therefore, it is best to keep both oil supplies for cranking active, and they should be activated before starting the cranking process. In special cases, if cranking is required for an extended period of time, it is advisable to turn off the oil injectors intermittently.
The auxiliary oil pump must be started first before cranking the engine, in order to prevent wear and damage to the bearing shells and crossheads
The auxiliary oil pump must be turned on; whether the filler is turned on depends on the design
The auxiliary oil pump must be started first before turning the shaft
Only after the auxiliary oil pump starts operating properly can the motor for turning the disk be connected and power supplied to turn the disk~~~~
For simple cranking, the oil injector can remain off, but the auxiliary oil pump must be turned on first
The lubrication system in the auxiliary oil pump is used to lubricate the bearings and crossheads. The auxiliary oil pump remains operational even when it is in standby mode; therefore, it is necessary to run the cranking auxiliary oil pump. The oil injector is used to lubricate the packing and cylinders; it is turned on only when the equipment is in operation. It needs to be turned on before rotating the equipment, and turned off after the rotation is complete, in order to prevent excessive oiling that could lead to carbon buildup.
