It is recommended to set a trial rivnut to ensure the correct stroke setting. The illustration below
shows the results of correctly and incorrectly set stroke.
If the stroke is set too long or there is a fault with the rivnut itself, it's possible that the rivnut may not
be released from the tool mandrel (#1) after setting.
To release the tool from the damaged rivnut, first loosen the knurled cover (#12), slide away the
sleeve (#56), then insert a 2.5mm diameter Allen-key through the stroke adjusting window into the
gap along the flat side of the nose pedestal (#10) and spring house (#5) which is positioned to the
side in the stroke adjusting window. Be sure that the nose pedestal (#10) and spring house (#5) are
secure with each other then hold on to the nose pedestal (#10) and the Allen-key clockwise. This
will also turn the mandrel (#1) clockwise therefore releasing the rivnut as shown:
TOOL OPERATION FOR SETTING RIVNUTS
1) After completing your start-up preparations and setting your stroke correctly, turn your rivnut
once onto the tool mandrel (#1) then apply light pressure to the end of the rivnut - the mandrel
(#1) will automatically thread itself into the rivnut. Place the mandrel (#1) with rivnut attached
into your pre-drilled work piece hole.
2) Pull the tool trigger (#53) to set the rivnut in its position on work piece.
3) After setting the rivnut, release the trigger (#53). The mandrel (#1) will turn anti-lock wise
and release the tool from the set rivnut. If the tool is still not released from the set rivnut,
press the button at the back of compressed spring pedestal (#21), then the tool will be
released.
