GENERAL OPERATION

• Power tools cannot be used in potentially explosive

atmospheres unless especially designed for that purpose.

• Unexpected tool movement or breakage of inserted

tool may cause bodily injury.

• Power tools should be disconnected from their

energy source changing or servicing any parts.

• Never put any body part, clothing hair etc. between the

tool and the work area as serious bodily injury can result.

• Guard against the risk of being injured by

whipping air hoses.

• Guard against unexpected tool movement or

breakage of the rivet may cause injury.

• Unstable postures may not allow counteracting of

normal or unexpected movement of the air tool.

AIR SUPPLY

The oil and water extractor should not be mounted on or near the air
compressor.
The temperature of air is greatly increased during compression. As the air
cools down to room temperature, in the air line, on its way to the Air Power
Tool, the moisture contained in it condenses. Thus, for maximum
effectiveness, the oil and water extractor should be mounted at some point

SUGGESTED AIR LINE CONNECTION

After unpacking the air powered rivet gun, make sure all of
the parts listed are supplied. In addition to parts supplied are
two wrenches you will need for replacement of various parts
on the PR36. Keep the packages containing wrenches, one
3/32 rivet nosepiece, one set of jaws and the bottle in a safe
place. Install the plastic rivet catcher (bottle) (#PR36-15)
and add the ¼ NPT air nipple to the air inlet side located
near the base. Add a few drops of air tool oil or #10 Spindle
oil to the air inlet near the base of the air riveter also add a
drop or two of oil to the Nose Piece Jaws (#PR36-4) through
the end of the Nose Piece (#PR36-1). Next squeeze the
operating handle Trigger (#PR36-25) several times before
inserting a rivet.

in the air supply system where the temperature of the compressed air in the
line is likely to be lowest. Air lines must be properly drained daily. Each low
point in an air line acts as a water trap. Such points should be fitted with an
easily accessible drain. See diagram below. Pitch all air lines back towards
the compressor so that condensed moisture will flow back into the air
receiver where it can be drained off. Drain daily.

Adjust your air compressor air pressure to 90-120psi, (6.21-8.28 Bars).

NOTE:

If you use extra long air hoses more than 50 feet long you may have to increase the air pressure to compensate for reduced air operating pressure.

Always use clean, dry air that has been filtered and is free of dust, corrosives fumes or moisture. You should drain the air tank daily and

clean the filtering system as needed. To use more air pressure will shorten that air tools life and may lead to premature failure of this Air

Riveter Gun and could cause injury. Use the standard air supply information located in the above diagram.
