# Precautions for Use
1. Applicable Conditions: For dry, hardened grease blockages only; this tool cannot clear blockages caused by deep internal rust in oil passages or those completely welded shut by metal shavings or welding slag. In such cases, we recommend drilling through the blockage or replacing the oil nozzle.
2. This tool has a maximum output of approximately 500 PSI and cannot replace ultra-high-pressure industrial unclogging equipment; it is not suitable for oil passages that require higher pressure to clear.
3. Pressurization Procedure: You must secure the hex nut on the main body! Do not grip the outer casing and rotate it to apply pressure; only turn the pressurization screw at the top. Gripping the outer casing and twisting it will directly cause the casing and plug to crack or break; such damage caused by user error is not covered by the warranty.
4. This tool is an auxiliary clearing tool and assumes no liability for damage to workpieces or stripped fuel injector threads. In older equipment, the threads of the fuel injector may already be corroded; fuel injector breakage may occur during the pressurization process, which is an objective condition inherent to aging components.
5. Do not operate under compressed air; be sure to apply grease before use. Pressurizing the tool without grease will damage the internal piston seals and shorten the tool’s service life.
6. After use, clean any grease residue from the tool and store it in a dry place; do not expose it to rain or water to prevent internal parts from rusting or seizing.
