An operator is preparing to attach a bucket to a telehandler. After connecting the hydraulic lines, the operator notices that the bucket does not tilt forward or backward when the control lever is activated. The telehandler's main hydraulic functions (boom lift, boom extend) are working correctly. What should be the first step in troubleshooting this issue?

Question: An operator is preparing to attach a bucket to a telehandler. After connecting the hydraulic lines, the operator notices that the bucket does not tilt forward or backward when the control lever is activated. The telehandler's main hydraulic functions (boom lift, boom extend) are working correctly. What should be the first step in troubleshooting this issue?

Answer options:

• Check the hydraulic pressure of the main pump. ✅ Verify that the auxiliary hydraulic circuit for the attachment is engaged.
• Inspect the bucket's mechanical connection pins.
• Replace the hydraulic tilt cylinders on the bucket.

Correct answer: Verify that the auxiliary hydraulic circuit for the attachment is engaged.

Explanation: Many telehandlers require the activation of an auxiliary hydraulic circuit, often via a dashboard switch or lever, to enable hydraulic functions for attachments. If other main functions are working, the problem is likely specific to the attachment's circuit. Checking main pump pressure or replacing cylinders would be premature steps; inspecting mechanical pins is for physical connection, not hydraulic function.
