This instruction manual must be read with particular attention to the following safety rules,
by any person installing, operating, or servicing this tool.
DO NOT USE OUTSIDE THE DESIGN INTENT.
DO NOT USE EQUIPMENT WITH THIS TOOL/MACHINE OTHER THAN THAT
RECOMMENDED AND SUPPLIED BY AVDEL.
ANY MODIFICATION UNDERTAKEN BY THE CUSTOMER TO THE TOOL/MACHINE,
NOSE ASSEMBLIES, ACCESSORIES OR ANY EQUIPMENT SUPPLIED BY AVDEL OR THEIR
REPRESENTATIVES, SHALL BE THE CUSTOMER'S ENTIRE RESPONSIBILITY. AVDEL WILL BE
PLEASED TO ADVISE UPON ANY PROPOSED MODIFICATION.
THE TOOL/MACHINE MUST BE MAINTAINED IN A SAFE WORKING CONDITION AT
ALL TIMES AND EXAMINED AT REGULAR INTERVALS FOR DAMAGE AND FUNCTION BY
TRAINED COMPETENT PERSONNEL. ANY DISMANTLING PROCEDURE SHALL BE
UNDERTAKEN ONLY BY PERSONNEL TRAINED IN AVDEL PROCEDURES. DO NOT DISMANTLE
THIS TOOL/MACHINE WITHOUT PRIOR REFERENCE TO THE MAINTENANCE INSTRUCTIONS.
CONTACT AVDEL WITH YOUR TRAINING REQUIREMENTS.
THE TOOL/MACHINE SHALL AT ALL TIMES BE OPERATED IN ACCORDANCE WITH
RELEVANT HEALTH AND SAFETY LEGISLATION. IN THE U.K. THE “HEALTH AND SAFETY AT
WORK ETC. ACT 1974” APPLIES. ANY QUESTION REGARDING THE CORRECT OPERATION
OF THE TOOL/MACHINE AND OPERATOR SAFETY SHOULD BE DIRECTED TO AVDEL.
THE PRECAUTIONS TO BE OBSERVED WHEN USING THIS TOOL/MACHINE MUST BE
EXPLAINED BY THE CUSTOMER TO ALL OPERATORS.
ALWAYS DISCONNECT THE AIRLINE FROM THE TOOL/MACHINE INLET BEFORE
ATTEMPTING TO ADJUST, FIT OR REMOVE NOSE EQUIPMENT.
DO NOT OPERATE A TOOL/MACHINE THAT IS DIRECTED TOWARDS ANY PERSON(S).
ENSURE THAT VENT HOLES DO NOT BECOME BLOCKED OR COVERED AND THAT
HOSES ARE ALWAYS IN GOOD CONDITION.
3
In addition to the general safety rules opposite, the following specific safety points must also
be observed:
THE OPERATING PRESSURE SHALL NOT EXCEED 7 BAR - 100 LBF/IN2.
DO NOT OPERATE THE TOOL WITHOUT FULL NOSE EQUIPMENT IN PLACE.
WHEN USING THE TOOL, THE WEARING OF SAFETY GLASSES IS REQUIRED BOTH BY
THE OPERATOR AND OTHERS IN THE VICINITY TO PROTECT AGAINST FASTENER
PROJECTION, SHOULD A FASTENER BE PLACED ‘IN AIR’. WE RECOMMEND WEARING
GLOVES IF THERE ARE SHARP EDGES OR CORNERS ON THE APPLICATION.
TAKE CARE TO AVOID ENTANGLEMENT OF LOOSE CLOTHES, TIES, LONG HAIR,
CLEANING RAGS ETC. IN THE MOVING PARTS OF THE TOOL WHICH SHOULD BE KEPT DRY
AND CLEAN FOR BEST POSSIBLE GRIP.
WHEN CARRYING THE TOOL FROM PLACE TO PLACE KEEP HANDS AWAY FROM THE
TRIGGER/LEVER TO AVOID INADVERTENT START UP.
ALWAYS ADOPT A FIRM FOOTING OR A STABLE POSITION BEFORE OPERATING THE
TOOL AND BE AWARE OF A TORQUE REACTION ON THE HANDS WHEN THE TOOL IS
OPERATING, PARTICULARLY DURING THE REVERSING SEQUENCE. GRIP THE TOOL FIRMLY
TO BE ABLE TO COUNTER THE TORQUE REACTION, BUT NOT TOO TIGHTLY.
KEEP HANDS AWAY FROM THE ROTATING DRIVE SCREW AND THE NOSE END OF
THE TOOL. IF A FASTENER BECOMES JAMMED ON THE DRIVE SCREW, SHUT OFF THE AIR
SUPPLY AND DRAIN THE SUPPLY LINE TO THE TOOL BEFORE ATTEMPTING TO DISLODGE IT.
THE TOOL IS NOT ELECTRICALLY INSULATED.
THIS TOOL IS NOT DESIGNED FOR USE IN COMBUSTIBLE OR EXPLOSIVE
ATMOSPHERES.
The pneumatic 07412 type tool is designed to place Avdel threaded inserts at high speed making it ideal for batch or flow-line assembly
in a wide variety of applications throughout all industries.
Use the selection table page 9 to select a complete tool which will be fitted with the correct nose equipment for the threaded insert
selected.
It is also possible to order the base tool only (part number 07412 - 00400). For details of nose equipment see pages 8 and 9.

A I R S U P P L Y
All tools are operated with compressed air at an optimum pressure of 5.5 bar. We recommend the use of pressure regulators and
automatic oiling/filtering systems on the main air supply. These should be fitted within 3 metres of the tool (see diagram below) to ensure
maximum tool life and minimum tool maintenance.
Air supply hoses should have a minimum working effective pressure rating of 150% of the maximum pressure produced in the system
or 10 bar, whichever is the highest. Air hoses should be oil resistant, have an abrasion resistant exterior and should be armoured where
operating conditions may result in hoses being damaged. All air hoses MUST have a minimum bore diameter of 6.4 millimetres or

When placing Standard Nutserts, lubricate the drive screw of the tool every 25 placings. This is best achieved by wiping
the drivescrew with a sponge soaked with STP Lubricant part number 07992-00013

OPTION 1
Ensure that the correct nose equipment is fitted.
Connect the tool to the air supply.
Place the insert into the prepared hole of the application.
Locate the drivescrew of the tool into the insert.
Operate the throttle lever (item 33 page 15) and hold. The
drivescrew will screw and collapse the insert.
To release the tool from the insert, press the reverse valve
button (item 51 page 15) whilst still holding the throttle lever
down. The drivescrew will reverse out of the insert.
OPTION 2
Ensure that the correct nose equipment is fitted.
Connect the tool to the air supply.
Screw the insert lip first onto the drivescrew of the tool.
With the insert on the tool, locate it into the prepared hole of
the application.
Operate the throttle lever (item 33 page 15) and hold. The
drivescrew will screw and collapse the insert.
To release the tool from the insert, press the reverse valve
button (item 51 page 15) whilst still holding the throttle lever
down. The drivescrew will reverse out of the insert.

Whether supplied as a assembly (part number 08412-00380) or within a complete tool, the clutch is supplied unset.
Correct clutch setting is necessary to ensure optimum deformation of the insert. If the deformation is insufficient (clutch torque too low)
the insert will rotate in the application. If the deformation is excessive (clutch torque too high), thread distortion will occur and extensive
wear on the drivescrew may lead to fracture.
I M P O R T A N T
The air supply to the tool must be disconnected when adjusting the torque of the clutch
Slide round the cover of the clutch housing (item 68 page 15) until you can see the serrations of the adjustment nut of the clutch
(item 15 page 15).
Using the clutch adjuster key supplied with the tool, turn the adjustment nut clockwise to decrease the torque or anti-clockwise to
increase the torque.
Turn the key one full turn at a time and test the tool having rotated the clutch housing cover back in place. Repeat as required.
After dismantling the clutch, we suggest that you set the torque to its minimum by turning the key fully clockwise then adjust by turning
the key anti-clockwise two turns at a time until the correct torque is acheived.

If you have purchased a complete tool, it will already be fitted with the correct nose equipment for your insert.
It is essential that the correct nose equipment is fitted prior to operating the tool. By knowing your original complete tool part number
or the details of the insert to be placed, you will be able to order a complete combination of nose equipment by referring to the table opposite.
FITTING INSTRUCTIONS
I M P O R T A N T
The air supply must be disconnected when fitting or removing nose equipment unless specifically instructed otherwise.
Before fitting the nose equipment, ensure the clutch on the tool is set to the correct torque for the insert being placed. (Torque settings
are shown on the table opposite.)
Ensure spring (item 83 page 15) is fitted to the base tool.
Insert drive shaft 5into head of tool.
Place washer 2onto drive screw 4, then bearing washer 3and second washer 2, as shown on illustration below.
Lubricate as per servicing instructions below.
Slide nose 1onto drive screw 4noting orientation.
Push this sub-assembly onto the drive shaft aligning the hexagon of the drive shaft with the hexagonal hole in the drive screw.
Screw on locking cap 6to retain nose equipment components.

NO S E E Q U I P M E N T
SERVICING INSTRUCTIONS
Nose equipment should be serviced at weekly intervals.
Remove the complete nose equipment using the reverse procedure to the ‘Fitting Instructions’.
Any worn or damaged part should be replaced by a new part.
Particularly check wear on drivescrew, thrust washers and thrust bearing.
Lubricate thrust washers and thrust bearings with high pressure grease (eg Shell Alvania E.P.I.)
Check spring is not distorted.
Assemble according to fitting instructions.
