Before first use, add 200ml of refrigeration oil to the compressor (pre-filled in some regions). We recommend using Gaahleri’s official designated oil or refrigeration oil.

IMPORTANT: Please fill the provided 200ml refrigeration oil before use.

If the oil appears darkened or the level is low, please replace it promptly to prevent overheating or damage. For optimal performance, we recommend replacing the oil proactively after 200 hours of operation.

Always switch off the compressor after use. Periodically drain accumulated water from the tank and the moisture trap. Store the equipment in a well-ventilated, dry area at all times.

CNC-Machined Full Aluminium Body.

The GTX-778 is tough, lightweight, and refined. A tool that looks as good as it performs silently.
