Why is my Power Fist 8558777 Nail Gun not shooting fasteners?
If your Power Fist Nail Gun is not shooting fasteners, there are a couple of potential reasons. It could be due to a damaged pusher spring, which would need replacing. Alternatively, you might be using the wrong size of fasteners. Make sure to use 1/2 in. crown staples or 1-1/2 in. to 2 in. nails.
Why is my Power Fist 8558777 lacking power and slow to cycle?
If your Power Fist Nail Gun lacks power or cycles slowly, the issue might stem from several causes. First, the tool may be too dry; try adding about 2-3 drops of lubrication into the air connector. Second, the air pressure could be too low; ensure your air compressor is set between 70 psi and 110 psi. Finally, the exhaust might be blocked; in this case, clean the exhaust channel.
What to do if fasteners are jammed in my Power Fist 8558777 frequently?
If your Power Fist Nail Gun is frequently jamming fasteners, several factors could be at play. The drive channel might be worn, requiring fixing. Alternatively, the piston could be broken or worn, necessitating replacement. Bent fasteners can also cause jams; remove them and replace them with 1/2 in. crown staples or 1-1/2 in. to 2 in. nails. A dirty magazine could be the culprit; clean it thoroughly. A loose magazine can also cause jams; tighten the screws. Finally, incorrect fasteners can lead to jamming; verify that the fasteners are the correct size.
