and tighten by wrench. The limit fixing sleeve (b) shall be installed on the nose assembly after the grip range is successfully
adjusted.
Adjusting Rules
A. （a）Fixing sleeve（b）Limit fixing sleeve（c）Adjusting sleeve (d) Limit sleeve
B. To refer the following picture: The scale value (0-4) on limit sleeve (d) represents the grip range (adjusting to
No.2 scale value means the grip range is 2mm). The operations are as follows: The limit fixing sleeve (b) shall be
rotated along anticlockwise direction and the adjusting sleeve (c) shall be rotated along clockwise direction and
limit sleeve (d) will move inward (the scale value will be changed gradually from 0 to 4, on the contrary, if the
adjusting sleeve is rotated along counterclockwise direction, the value will be changed gradually from high to
low). After the scale is confirmed, the limit fixing sleeve (b) shall be rotated along anticlockwise direction to
connect firmly with fixing sleeve (a), and the grip range can not be changed when tightening.
Note: The grip range is from 0 to 5mm (carrying out the riveting operation only within the adjusting range
from 0 to 5mm), if the operation exceeds the grip range, the tool will be damaged. Therefore, please do not
exceed the allowable grip range and do not press the tool switch to adjust the grip range!
