Product Overview

This manual section provides detailed instructions on how to check the pressure setting of the relief valve in your machinery. Proper maintenance of the relief valve is crucial for ensuring smooth operation and prolonging the life of your equipment.

Key Features

• Step-by-step procedure for checking pressure settings
• Guidelines for optimal oil temperature
• Instructions for using a pressure gauge effectively
• Specifications for assessing gauge readings

Benefits

• Ensures machinery safety and operational efficiency
• Reduces the risk of equipment malfunction
• Provides clear guidance for accurate maintenance checks

Usage Recommendations

• Park the machine on a level surface and lower any attachments to the floor.
• Ensure the oil reaches the required operating temperature:
  • Run the engine at full throttle, holding the loader control lever in the ROLLBACK position for 15 seconds.
  • Move the loader control lever to NEUTRAL for 15 seconds.
  • Repeat until the oil is at 125u00b0F (51u00b0C), or the reservoir feels very warm.
• Attach a pressure gauge (capacity of at least 4000 psi, 27 580 kPa, 276 bar) to the quick disconnect fitting at Test Port 1, located inside the LH frame rail to the left of the engine.
• Turn the steering wheel completely to the right or left while running the engine at full throttle and record the pressure reading.
• Reduce the engine to low idle for two minutes before stopping it.
• Compare your recorded pressure reading against the specifications provided on page 2 of the manual.
• If the reading is incorrect, refer to Section 5002 for repair or replacement of the steering control valve.

For an in-depth understanding, kindly follow manual guidelines diligently. Ensuring that all maintenance steps are adhered to will improve the performance and upkeep of your machine.
