Question about Dewalt D51256K 16 gauge finish nailer kit
If air escapes from the trigger as soon as you connect air, most likely bad trigger valve or needs orings in valve. If air leaks from the trigger when you attempt to fire the gun, then internal orings are at fault. If leaks when attempting to fire, remove head and lube all the orings with silicone paste lube (sold at Lowes or swimming pool supply) and retest. If gun fires after lube, order oring kit or keep using till trouble. If you need to replace the trigger valve, remove nails for safety and the trigger to expose the valve. Remove the rollpins holding the valve into body. Apply air to gun and catch the valve as it pops out with a gloved hand (use caution because the valve could come out with force).
