Personal injury or death can result from not engaging the parking brake.Transmission engagement alone will not prevent machine from rolling when the engine is stopped.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.

The power train oil pump is a two-section pump. One section of the pump provides the lubrication. The other section scavenges oil from the bottom of the electric drive propulsion module. The following test will determine whether the pressure of the power train oil pump is within the specified limits.Required Tools
This test may be conducted while the tractor is in motion or this test may be conducted with the tractor elevated so that the tracks are free to move in both directions. No special tooling is required in order to conduct this test. The power train lubrication pressure can be found on the monitoring system display.

Test Preparation
Move the machine to a smooth horizontal location.
Use suitable lifting devices in order to lift the machine. The tracks must be able to turn freely in both directions.
Place the steering control lever in the NEUTRAL position.
Engage the parking brake.
Lower the attachments to the ground.
Stop the engine.
Turn the key to the ON position, but do not start the engine.
Verify that the implement lockout switch is in the UNLOCKED position.
Move the control levers through the full range of travel several times. Moving the control levers should relieve any pressure that may be present in the implement hydraulic system.
Make sure that the pressure in the entire hydraulic system has been released.
Turn the key to the OFF position.
Observe the state of the amber hazardous voltage present lamp. If the lamp is illuminated, do not perform any type of service on the machine. Wait until the lamp is not illuminated. Then, perform the lamp test in the next step.
While you observe the lamp, turn the disconnect switch to the
