Part No. 237062 Z-45/25 Bi-Energy • Z-45/25J Bi-Energy 3 - 23September 2015 Section 3 • Scheduled Maintenance ProceduresB-12Test the Drive BrakesProper brake action is essential to safe machineoperation. The machine uses drive motorregenerative braking to stop the machine.Hydraulically-released individual wheel brakes holdthe machine once it has stopped. The drive motorregenerative braking should operate smoothly, freeof hesitation and jerking. Hydraulically-releasedindividual wheel brakes can appear to operatenormally when not fully operational.Collision hazard. Be sure that themachine is not in free-wheel orpartial free-wheel configuration.Refer to B-6,Confirm the ProperBrake Configuration.Note: Select a test area that is firm, level and freeof obstructions.1 Mark a test line on the ground for reference.2 Lower the boom into the stowed position.3 Choose a point on the machine; i.e., contactpatch of a tire, as a visual reference for usewhen crossing the test line.4 Bring the machine to maximum drive speedbefore reaching the test line. Release the drivejoystick when your reference point on themachine crosses the test line.5 Measure the distance between the test line andyour machine reference point. Refer toSection 2,Specifications.Note: The brakes must be able to hold the machineon any slope it is able to climb.B-13Test the Drive Speed -Stowed PositionProper drive function movement is essential to safemachine operation. The drive function shouldrespond quickly and smoothly to operator control.Drive performance should also be free ofhesitation, jerking and unusual noise over theentire proportionally controlled speed range.Note: Select a test area that is firm, level and freeof obstructions.1 Create start and finish lines by marking two lineson the ground 40 feet / 12.2 m apart.2 Lower the boom into the stowed position.3 Choose a point on the machine; i.e., contactpatch of a tire, as a visual reference for usewhen crossing the start and finish lines.4 Bring the machine to maximum drive speedbefore reaching the start line. Begin timingwhen your reference point on the machinecrosses the start line.5 Continue at full speed and note the time whenthe machine reference point passes over thefinish line. Refer to Section 2,Specifications.CHECKLIST B PROCEDURES
