[ WARNING ]
The proper Stroke Distance is decided as per the WORKPIECE Thickness and the Grip Range of RIVET NUT.
Each RIVET NUT has its own Grip Range, the Maximum Grip and Minimum Grip.
The WORKPIECE Thickness must be WITHIN the Grip Range of RIVET NUT or BETWEEN the Maximum Grip
and Minimum Grip of RIVET NUT for safe and firm fastening.
If the Maximum Grip of RIVET NUT is SMALLER than the WORKPIECE Thickness, this TOOL and RIVET NUT
Threads might be damaged.
If the Minimum Grip of RIVET NUT is LARGER than the WORKPIECE Thickness, this RIVET NUT cannot be
gripped firmly in the WORKPIECE.
Adjusting TOO LONG Stroke Distance might damage this TOOL and RIVET NUT Threads, while TOO SHORT
Stroke Distance cannot fasten RIVET NUT firmly in the WORKPIECE.

PRECAUSION:
Before operating this TOOL, it is strongly requested to follow the above "E" to install the correct size of
THREADED MANDREL and NOSEPIECE, the above "F" to adjust the proper Stroke Distance, and the above
"G" to adjust the Protruding Length (L) of THREADED MANDREL to ensure perfect fastening work between
TOOL and RIVET NUT.
[ WARNING ]
If hand force CAN NOT squeeze 2 HANDLES to touch
REAR BODY, DO NOT CONTINUE TO SQUEEZE 2
HANDLES, it may be caused by TOO LONG Stroke
Distance. REDUCE The Stroke Distance immediately
to protect this precious TOOL and RIVET NUT Thread
from damage. See TROUBLESHOOTING K-2).
NOTE:
It is always suggested to SQUEEZE 2 HANDLES WITH
BALANCED HAND FORCE to deform RIVET NUT a
Normal Bulge against the back of WORKPIECE.

2 HANDLES TO TOUCH REAR BODY, HOW TO RE-ADJUST THE CORRECT
STROKE DISTANCE TO PROTECT THIS TOOL AND RIVET NUT THREAD
FROM DAMAGE:
11
As the Stroke Distance has been re-adjusted, the
Protruding Length (L) of THREADED MANDREL
needs to be adjusted again to be same as RIVET NUT
Height (H), L = H, as per the above "G" instruction.

K-3) HOW TO SOLVE THE PROBLEM OF RIVET NUT STUCK ON THE THREADED
MANDREL WHEN RIVET NUT SCREWS ONTO THREADED MANDREL'S
THREADS BY TURNING THE ROTATING KNOB:
K-4) HOW TO SOLVE THE PROBLEM OF RIVET NUT STUCK ON THE THREADED
MANDREL WHEN SQUEEZING 2 HANDLES AND DEFORMING RIVET NUT IN
THE WORKPIECE ABNORMALLY:
1 2
Open 2 HANDLES a little bit , rotate whole TOOL to align the
FIXING-HOLES of HEAD with the inside LONG FIXING-HOLE
of MANDREL SEAT , then plug the FIXING-HOLE PIN into
these FIXING-HOLES and put the PIN RETAINER onto
FIXING-HOLE PIN End , the free rotation of THREADED
MANDREL is therefore stopped.
