Test Service Brake Holding Ability
Be sure the area around machine is clear of personnel and obstructions.Be sure the steering frame lock link is in the stored position.Test the brakes on a dry, level surface.Fasten the seat belt before testing the brakes.The following tests are to determine if the service brake is functional. These tests are not intended to measure maximum brake holding effort. Brake holding effort required to hold a machine at a specific engine rpm will vary from machine to machine due to differences in engine setting, power train efficiency, etc., as well as differences in brake holding ability.Engine rpm at beginning of machine movement, with service brake applied, should be compared against the engine rpm your specific machine was able to hold on a prior test, as an indication of system deterioration. 1. Start the engine, and raise the bucket slightly. Apply the service brake and release the parking/secondary brake. 2. With the service brake applied (right brake pedal only). Move the transmission to 2nd speed reverse. 3. Gradually increase the engine speed to high idle. The machine should not move.
If the machine begins to move, reduce the engine speed immediately and engage the parking/secondary brake.
4. Reduce the engine speed to low idle, move the transmission to NEUTRAL. Engage the parking/secondary brake, lower the bucket to the ground and stop the engine.
If the machine moved
