LEVER (Front Right Hand) 7K3755 - Caterpillar

Personal injury can result if the machine moves while checking the service brakes.If the machine begins to move during the check, reduce the engine speed immediately and engage the parking brake.
This test will determine if the service brakes are functional. The test is not intended to measure the maximum brake holding effort. The brake holding effort that is required to sustain a machine at a specific engine rpm varies depending on the machine. The variations are the differences in the engine setting, in the power train efficiency, and in the brake holding ability.Test the brakes on a dry, level surface. Make sure that the area around the machine is clear. Move the machine away from other operating machines and away from personnel.
