7.9 Testing the Control Interlock System
When
Every 10 hours or daily
Procedure
To enable the ground drive, loader lift and tilt, and auxiliary hydraulics, the
operator must complete all of the following actions:
1. Stand on the operator platform and engage the operator presence
pedal.
2. Start the engine.
3. Disengage the parking brake.
To test the control interlock system, perform the following functions individu-
ally with the engine running and the controls enabled. A successful test
means that the machine will not move after each of the following tests are
performed:
• Disengage the operator presence pedal, wait 5seconds, and move the
ground drive controls, lift arm controls, and auxiliary hydraulic controls.
• With operator presence pedal engaged, disengage the parking brake
and move the ground drive control only.
Note: After all controls are enabled, pressing the brake switch will only en-
gage the parking brake and limit the ground drive controls to hold the ma-
chine stationary. This allows the machine to operate the lift arm controls or
auxiliary controls while preventing the machine from moving—for example,
drilling a post hole while working on a slope.
Testing the lift arm controls interlock
1. Stand on the operator platform with the operator presence pedal en-
gaged and start the engine.
2. Raise the lift arm slightly off the ground.
3. Shut down the machine and wait for the engine to stop completely.
4. Make sure the area around the machine is clear.
5. Move the right joystick forward to lower the lift arm.
ð The lift arm should not lower.
