Inspect for damaged or missing motion alarm decal (Item 1) [Figure 50-130-1] (cab machine) or (Item 1) [Figure 50-130-2] (canopy machine). Replace if required.
NOTE: The excavator will need to be moved slightly in both the forward and reverse direction to test the motion alarm. Keep all bystanders away from machine during test.
Sit in the operatorโs seat and fasten the seat belt. Start the engine.
Move the travel control levers (one lever at a time) in the forward direction. The motion alarm must sound. Move the travel control levers (one lever at a time) in the reverse direction. The motion alarm must sound.
Slightly move both travel control levers in the forward direction (until the machine is slowly moving forward) and then press the motion alarm cancel switch (Item 1) [Figure 50-130-3]. The motion alarm will shut off. With the machine still moving forward, move one of the levers to the neutral position, the motion alarm must sound.
Slightly move both travel control levers in the reverse direction (until the machine is slowly moving backward) and then press the motion alarm cancel switch (Item 1) [Figure 50-130-3] (the switch icon will be illuminated when the motion alarm is deactivated). The motion alarm will shut off. With the machine still moving backward, move one of the levers to the neutral position, the motion alarm must sound.
Return both levers to neutral and turn excavator key to OFF position. Exit the excavator.
The motion alarm is mounted to the bottom rear of the excavator. (To the front of the engine oil pan.)
Inspect the motion alarm electrical connections and wire harness (Item 1) [Figure 50-130-4], wire harness (Item 1) [Figure 50-130-5] and motion alarm switch (Item 2) [Figure 50-130-5] for tightness and damage. Repair or replace any damaged components.
If the motion alarm switch requires adjustment, see the following information.
