Cylinder Cycle Time - Check
Before you begin the following procedure, refer to Testing and Adjusting, "Machine Preparation for Troubleshooting".
- Start the engine. Operate the machine until the hydraulic oil reaches normal operating temperature.
- Make sure that the scraper bowl is empty. Stop the machine on a hard, level surface. Run the engine at HIGH IDLE in NEUTRAL.
- Lower the scraper bowl to the ground. Lower the apron.
- Raise the apron. Refer to Table 1 for the time that is required to completely raise the apron.
- Lower the apron completely from the maximum height. Refer to Table 1 for the time that is required to lower the apron.
- Raise the apron to the maximum height.
- Raise the scraper bowl to the maximum height. Refer to Table 1 for the time that is required to raise the scraper bowl.
- Lower the scraper bowl to the ground without placing the bowl control in the QUICK-DROP position. Refer to Table 1 for the time that is required to lower the scraper bowl.
- Retract the ejector completely.
- Move the ejector to the front of the scraper bowl. Refer to Table 1 for the time that is required to move the ejector forward completely.
- Retract the ejector completely. Refer to Table 1 for the return time of the ejector.
