SLEEVE-SPACER 2383298 - Caterpillar

Keep engine speed low and do not operate until the message 'Warm-Up Mode Power Derate" on the monitor goes out. If it does not go out within thirty seconds, stop the engine and investigate the cause before starting again. Failure to do so, can cause engine damage.
Always run the engine at low idle for at least ten minutes before performing any other operations in cold conditions or each time the engine oil and oil filter are changed in order to protect your engine and hydraulic components.
Depending on the ambient temperature, in order to prevent the machine operation with high speed without sufficient lubrication at the turbo bearing, the engine speed may be set to low speed and the hydraulic power minimized for a pre-determined time after the engine starts. Refer to turbo protection feature.
The engine may automatically change speeds when the machine is stationary and idling in cold ambient temperature for an extended time. This is to:
Maintain desired coolant temperature.
Maintain desired operation of engine systems.
Maintain desired operation of the regeneration system.During extended idling in cold ambient conditions, engine speed may operate between 900 rpm and 1000 rpm. Operation at 1000 rpm is minimal and will only last for up to 20 minutes. The regeneration active indicator may also illuminate during extended idling conditions to signal that a regeneration is in progress.Hydraulic System
When you cycle the machine controls, the machine can move suddenly. Contact between the machine and external objects or ground personnel can result in serious injury or death. Before you cycle the machine controls, the machine should be located in an unobstructed, hazard-free work area that is away from external objects and ground personnel.
Make sure that the area is clear of personnel and equipment.Note: The hydraulic lockout control must be in the UNLOCKED position before the hydraulic controls will function.
Allow the engine to warm-up at low idle for at least 5 minutes. Engage the work tool controls and disengage the work tool controls. This will speed up the warm-up of the hydraulic components.When you idle the machine for warm-up, observe the following recommendations:
If the temperature is greater than 0°C (32°F), warm up the engine for approximately 15 minutes.
If the temperature is less than 0°C (32°F), warm up the engine for approximately 30 minutes.
If the temperature is less than − 18°C (0°F) or if hydraulic functions are sluggish, additional time may be required.
The hydraulic oil temperature should be higher than 25 °C (77 °F) before performing work with the machine. Make sure that the warm-up procedure is performed.If the hydraulic oil temperature is less than 25 °C (77 °F) and the machine is operated abruptly, serious damage to the hydraulic components may occur.
Note: The recommended operating temperature of the hydraulic fluid for this machine is 55 °C (131 °F).
To warm up the hydraulic oil, turn the engine speed dial to the medium engine speed.
Run the engine for approximately 5 minutes and move the joystick intermittently from the BUCKET DUMP position to the HOLD position. Do not hold the
