TRE 500 Staples don't go in deep enough.

It is actually made by Stanley and has a Master Mechanic badge on it.

The Stanley TRE300 stapler and it's staples have been discontinued and are no longer available. However, the Sears brand extra wide crown staples will fit this stapler.

Hi!
The Stanley TRE 300 is an electric stapler/nailer.
It will accept 1/4" 5/16", 3/8", 1/2" & 9/16" staples and 1/2" & 5/8" brad nails. How much? Depending on the size of nails or staples.
BTW it's a great little machine :)

There is no depth adjustment on this tool -
If the staples are going too deep - most likely the piston (#17) has threaded off the driver inside the tool, you have a broken piston bumper (#62) inside, or the teflon foot pad (#56) on the bottom of the tool is the wrong thickness for the flooring you are using.
If the staples are not driving far enough - most likely you have a broken / chipped driver blade (#21) or the teflon foot pad (#56) on the bottom of the tool is the wrong thickness for the flooring you are using.



Detail

I believe on that model you have to release the magazine latch, pull the lower half all the way back, load the staples into the upper half of the magazine, then close and latch the lower half. The staple pusher and spring are located in the lower half so the staples need to be in front of that for them to be properly pushed into the nose. Also make sure you are running the correct staple. There are 1/4" and 3/16" narrow crown staples out there and they don't interchange. The staples should slide freely in the magazine when they are loaded.

Hi Nancy,

Do you mean it rapid fires, or do you mean fires the staples to deep?
If it fires too deep, the adjustment for that is on the back of the gun. The + and - give more/less depth. Adjust it towards the - direction to get the brad/staple to no penetrate as far.

Thanks,

Hi,
That is a common problem with those guns...have returned quite few of them that did not last more then a few hundred staples...my local hardware returned them got credit for them and gave me new ones...they are a poor excuse for a staple gun but there is not much of an alternative to them...

The working pressure of this tool is 85 - 90 PSI max. Do not over power it or you risk O-ring breakage. These guns are adjustable for floor thickness. The adjustment is simply by adding and removing shims on the floor contact part of the tool. For 3/4" the pad should be 5/16" thick without shims

Go to website and type in tre550 and you will find a copy of a PDF instruction. It is very limited. They also have a tool tips area.

Either the pioston backed off piston stem or the blade is broken. remove 4 bolts holding shoe to yellow body. remove magazine and shoe. remove yellow bumper inside gun. Pull piston down and inspect blade. if not broken see if piston backed off stem. if so gun must be rebuilt and part # BC347 must be replaced. visit www.bostitch.com and download schematic and where parts can be obtained.
