Operation 

 

The riveter must be properly 

lubricated before operation. See “Lubrication” 
section. 

 

The  safety  cap  must  be 

installed before operating riveter.

 

1. 

Select  nosepiece  that  best  fits  rivet  being 
used. 

2. 

Use wrench to unscrew nosepiece counter-
clockwise. See Figure 2.  

 

Figure 2 

3. 

Push  new  nosepiece  into  jaws  against  the 
spring  tension,  and  rotate  until  threads 
engage. Tighten nosepiece with wrench. 

4. 

Remove protective cap from air inlet (Figure 
1). If an in-line oiler is not being used, add 4 
or 5 drops of air tool oil (not included) into the 
air inlet. 

5. 

Blow  out  air  line  to  remove  any  dirt  or 
moisture,  then  connect  air  supply  hose  to 
tool. Set air pressure to 90 psi. 

IMPORTANT:

  Connecting  a  quick-change 

coupling  directly  to  the  tool  is  not 
recommended,  as  vibration  may  cause  the 
connection to fail. Instead, add a leader hose 
and  install  any  quick-change  couplings 
farther down the line. 

6. 

Insert  rivet  mandrel  all  the  way  into 
nosepiece. 

7. 

Place rivet into hole so that rivet head makes 
contact with work surface. 

8. 

Press trigger to drive rivet.  

9. 

Release trigger to eject spent mandrel. 

Note: When  tool  is  facing  downward,  spent 
mandrels will exit through nosepiece. When 
tool is angled upward, spent mandrels will be 
caught  by  safety  cap.  Turn  safety  cap  slot 
upward to prevent spilling of mandrels.
