Hengwang Excavator Air Conditioning System: Operation and Maintenance Guide

1. Usage Precautions

• Do not activate the air conditioning immediately after starting the engine. Allow the engine to stabilize first to reduce unnecessary load.

• Run the air conditioning in idle mode weekly to ensure oil circulation and prevent compressor seizure due to oil deficiency.

• Adjust the temperature based on external conditions. Avoid excessively low settings to minimize engine load and fuel consumption.

• Choose appropriate modes (e.g., face, foot, or windshield airflow).

• Winter: Prioritize foot mode for cabin warmth.

• Summer: Use face mode for faster cooling.

• Use internal circulation in dusty or polluted environments.

• Switch to external circulation periodically to maintain air quality.

• Procedure: Use a manifold gauge to verify refrigerant levels. If low, inspect for leaks before refilling.

• Risks of Neglect: Poor cooling efficiency, compressor wear, or seizure.

• Procedure: Ensure wiring connections are secure. Clean accumulated dust or debris around the clutch.

• Risks of Neglect: Electrical failures, clutch wear, or shaft seal damage.

• Procedure: Check and clean/replace clogged filters regularly.

• Risks of Neglect: Reduced airflow, filter deformation, or evaporator blockage.

• Procedure: Remove accumulated dust or foreign objects from the condenser.

• Risks of Neglect: Corrosion, refrigerant leaks, poor heat dissipation, or high system pressure.

• Procedure: After prolonged inactivity (>7 days), run the air conditioning in idle mode for 5+ minutes before normal use.

• Risks of Neglect: Inadequate oil-refrigerant mixing, leading to compressor oil starvation and seizure.
