Oiling Your Pneumatic Nailer or Stapler Properly

Oil tools daily -

Many pneumatic tools use engines that require the use of rubber O-rings and those O-rings require lubrication in order to function properly. The following points will ensure that you are oiling your pneumatic tool properly:

1. Read your instruction manual and make sure that your pneumatic tool requires oil, and if so, the manual will tell you the recommended amount of oil and when to oil the tool. Some pneumatic tools are oil-less and may not require oil.

2. If you are using your pneumatic tool in a harsh climate, including those climates that are extremely high in humidity or cold temperatures, be sure to check with the tool manufacturer. These climates may require the use of oils
that are designed specifically for these climates.

3. Tools should be oiled prior to every use, and they should also be oiled prior to storage. Tools that sit in storage for an extended period of time without oil have a higher chance of drying out, thus damaging internal parts.

baumr ag User Manual Needed

  • There should if available for your model type a maintenance kit neccesary for your model or all the used o-rings and sometimes special tools because there are special buna-n or nbr o-rings used sometimes braun or green colored on some parts and gaskets, seals and rings used and allways if your tool is leaking then replace the impact bold in front of the spindle if you have find the right drawing for your model type
  • The right lubrication is very important in combination of the o-rings because of the heat building release by rotating and hammering and a leaking tool has oft made all o-rings hardenet because of the failed pneumatic working loose of lubrication dried out principal it becomes very dry internal on some places and much to hot .

Do anybody know if grease is used in palm nailer assembly? It contains cylinders and o-rings and my guess is only oil can be used. Otherwise grease will trap dust and create problems

When you assemble a palm nailer you need to use a light grease, usually included with rebuild kits, liberally on all o-rings and moving parts. This will insure the o-rings are not damaged during assembly. The air passing through the tool during use will blow out all the grease and oil so use pneumatic tool oil once or twice a day to keep the o-rings lubricated.

when i apply air to my framing gun the firing pin comes out and doesnt return

Try some oil in the gun, they have pneumatic tool oil, they should be oiled daily, though none of us really do this! If that doesn't fix it, it probably needs some new o-rings internally.

How do I fix the plunger ?

This can be caused by any number of reasons.

If your piston driver does retract and slowly slides back to the downward position. This is a good indication that your piston o-ring is worn and needs replacing.

However the most common cause of the problem in which the driver will not retract at all, is that an o-ring has broken or has popped off of your piston cylinder. This o-ring is located in the bottom chamber of the gun.

Generally if the tool has not had the o-rings replaced in over a year, and if the tool is used quite often, it is good to have all the o-rings replaced especially when they are in contact with moving parts. Also as a rule, if you are unfamiliar with pneumatic tool repair, remove only the parts necessary to your problem. Often one problem can compound to many if you interfere with parts that are working properly.

To make a quick repair take following steps:

Disconnect the tool from air supply.

Remove the head cap from the body by removing the 4 bolts on the top. Be careful not to tear the gasket if you do not have a replacement.

With a thin tool pop the piston driver out of the top, by pushing upwards from the nose end.

If tool has dirt, excess oil, or grit inside clean it up as much as possible especially around rubber o-rings. Keep in mind that the tool needs oil to remain lubricated, don't leave tool dry around o-rings.

Use two head cap screws to gently remove the cylinder plate that is now exposed around the piston cylinder. Gently pull upwards (friction and an o-ring hold this tightly in place).

Now you can remove the piston cylinder. It may pop up because it is spring loaded, or it may be stuck downward. Carefully work it loose so it can be removed.

Examine the o-rings on the cylinder. Are any out of position? If there are any broken they must be replaced. If one popped out of position, reposition it.

The o-ring that can cause this problem is most likely the large rubber ring that covers a series of smaller holes that are positioned around middle portion of the cylinder.

Replace parts in the reverse manner of removal. Lubricate o-rings with appropriate assembly grease which is best, or pneumatic tool oil.

When the cylinder plate is reassembled, make sure that the cylinder is up. In other words, the spring that is surrounding the cylinder below the plate must be released as much as possible. This will enable flush contact between the cylinder and the parts on the head cap when the tool is assembled fully.

Replace the gasket, head cap, and the four bolts.

Hook tool up to air supply, check for air leaks, test fire tool.
