Frequently Asked Questions
How do you change the tips on the GAH-15?
Tips can be easily swapped using a standard 1/4” hex wrench. Simply loosen the cap, slide out the valve assembly, and replace the tip. Ensure the O-ring is fitted to the new tip before reassembling.
Does it require a large compressor?
No. While it uses 10 CFM at maximum speed, its efficient design allows it to run on most mid-sized workshop compressors. For best results, keep the tool within 5m of your air source or use a small surge tank.
