Please refer to the TOOL EXPLOSIVE ILLUSTRATION and the PARTS LIST in this manual in order to have a
good understanding of the tool parts described. The descriptions of the tool parts appear in this manual are
in italics.
1) This pneumatic powered tool should be worked with compressed air supply. It is recommended to use the air
hose with diameter bigger than 8 mm.
2) To check the compressed air pressure within the specified range between 0,5Mpa and 0,7Mpa, and to connect
the air hose adaptor onto the tool air adaptor. The air adaptor has its different versions in different countries
and areas, normally the tools are equipped with the correct version as default, in case the air adaptor does not
apply in your air supply hose adaptor, contact the tool distributor(s).
3) To change and use correct cap screw and anvil according to the size of the rivet nut to be set. This tool is
equipped with cap screws and anvils from M3 up to M12 in the tool kit. For convenience, 7 identical locknuts
provided in the tool kit for each size of the cap screw and anvil in pairs. The steel grade for the screw puller
must be 12.9.
GETTING START TO WORK
a) To remove the anvil from the tool and the locknut
(spanner from the tool kit):
c) To remove the adaptor sleeve, the screw puller,
drive bar (M3 to M8) and drive bar washer (M3 to
M8) (17mm standard spanner + spanner from the
tool kit):
b) To remove the retaining ring and nose sleeve:
d) To assemble the spring into the drive bar
(M3 to M8), the drive bar (M3 to M8) into the cap
head of cap screw, the drive bar washer (M3 to M8)
on to the cap screw and the adaptor sleeve:
f) To install the nose sleeve and screw on the retaining
ring:
g) To screw on the locknut and anvil
(spanner from the tool kit):
e) To screw on adaptor sleeve tight with spring house
with spanners (17mm standard spanner + spanner
from the tool kit):

MANDREL PROTRUDING SET FOR BLIND NUT
STROKE SETTING
1) To set the length of the cap screw
protruding out of anvil according to blind
rivet nut length, by positioning of the
locknut and anvil locking each other:
1) It is very important step to define the stroke to be set on the
tool, by measuring the rivet nut and calculating in formula:
Stroke = A – ( B + C )
a) The tool stroke can be set from 1mm up to 7mm, and it shows by the indicate line pointing on to the graduation scale
precisely.
b) To increase the stroke: slide the stroke setting slider in the direction of the tool front (cap screw), turning the stroke setting
knob anti-clock wise, release the stroke setting slider back (to be sure the small needle tip seated back into the hole on the
edge of the stroke setting knob) and checking the indicate line pointing.
c) Repeat the operation until the indicate line pointing at the defined stroke; To reduce the stroke: operate in the same way but
turning the stroke setting knob clock wise.
2) Never to set the cap screw protruding length too long nor
too short according to the rivet nut to be set:
A= depth of the rivet nut (inside of the rivet nut non-threaded and no upset
part of the nut when setting)
B= total thickness of work piece(s)
C= rivet nut head thickness (if countersunk head rivet nut, then C = 0)
2) To set the stroke on the tool :

TO SET RIVET NUTS
3) Checking the set stroke by initial rivet nuts setting. It is extremely important to have precise stroke setting and
trial set on work piece and refer to the illustration below to see if you got a nice set up:
1) After start-up preparations, stroke setting and initial trial setting, to put the rivet nut into work piece hole
(pre-drilled), to insert the cap screw of the tool into the rivet nut and press the button of the tool, the operation
of the rivet nut setting will be automatically finished.
2) The tool, after the button pressed, the tool will automatically insert into the rivet nut and set the rivet nut on the
work piece then released automatically.
3) If users have not had the stroke setting correctly, the tool might can not be released, then follow the process
described below to release the tool:
4) If the tool operator used a bad quality rivet nut or improper stroke setting, the tool might be blocked on the set
rivet nut and work piece and can not be released according to the above 3) described, then to use the anti-
block sticker in the tool kit, insert into the slot-shaped hole on the nose sleeve, then turning the tool with force
anti-lock wise to release the tool.
a) Slightly press the release button at the rear of the tool.
b) Press the button of the tool, then the tool will be release from the set rivet nut.

2) To connect the air supply and to cover some cloth over
the hole where the screw removed, then to press the
button and the oil will be leaked out from the tool :
3) To screw the oil inject adaptor (on oil injection tube
set in the accessories pack) into the hole where screw
removed :
4) To use the oil injection tube (in the accessories pack)
to inject the oil slowly until not able to refill, to remove
the injection tube and its adaptor, then clean the oil on
the tool and tightly screw on the screw back to the tool:
5) To test the tool stroke. If the stroke still not enough
as it should be, it means there could be some air in the
oil cylinder when you refilling the oil to the tool. Then
the extra air needs to be released from the tool.
To connect the tool with air supply, to pull the tool button 6 or 7 times,
then loosen the screw , let the extra air leaking out, then screw on the
screw tight again:
TOOL MAINTENANCE
1) To remove the screw by hexagon wrench:
If there is no lubricating device connected in the air distribution,
daily and before starting work, for better performance of the tool,
add a few drops of hydraulic oil on the inlet of the air adaptor of
the tool in order to reduce the frictions of the tool parts since the
oil will be blown inside the tool when tool operates.
After certain period of use, the tool stroke might be reduced,
it shows the hydraulic oil of the pneumatic tool is necessary
to be refilled or changed:
