A loader operator is using a skid steer with a laser-guided grading attachment to prepare a base for a concrete slab. The laser receiver is mounted on the mast of the attachment. If the operator observes the 'low' indicator on the laser receiver, what is the appropriate corrective action?

Question: A loader operator is using a skid steer with a laser-guided grading attachment to prepare a base for a concrete slab. The laser receiver is mounted on the mast of the attachment. If the operator observes the 'low' indicator on the laser receiver, what is the appropriate corrective action?

Answer options:

• Lower the cutting edge of the grading attachment. ✅ Raise the cutting edge of the grading attachment.
• Increase the engine RPM to apply more hydraulic power.
• Move the loader forward faster to cover more ground.

Correct answer: Raise the cutting edge of the grading attachment.

Explanation: A 'low' indicator on a laser receiver means the cutting edge is too low relative to the desired grade established by the laser plane. To correct this, the operator needs to raise the cutting edge to match the laser plane. Lowering it would make the situation worse, and engine RPM or loader speed are not direct corrections for grade accuracy.
