IN T E N T O F U S E
The hydro-pneumatic 07391 tool is designed to place Avdel breakstem rivets at high speed making it ideal for batch or flow-line
assembly in a wide variety of applications throughout all industries.
The tool is designed to be operated with forward stem release nose assemblies. A complete tool will always be fitted with one of two
assemblies which includes a nose tip. One or two nose tips will be screwed into the base of the tool. To select a complete tool use both
tables opposite. In the first table identify your fastener and read the part number of the nose tip required to place this fastener.
`A’ and `B’ dimensions will help you assess the accessibility of your application. By finding the nose tip part numbers in the second
table you will be able to read the complete tool part number. There may be two complete tools which contain the nose tip, you may
select either.
It is also possible to order the base tool only part number 07391-00200.
Dimensions shown in bold are millimetres.
Other dimensions are in inches.

OPTION 1
Ensure that the correct nose equipment is fitted.
Connect the tool to the air supply.
Insert the fastener body squarely into the prepared hole of the
application.
Apply the tool to the protruding rivet stem.
Fully operate the trigger. The tool cycle will ensure the rivet is
placed.

PU T T I N G I N T O S E R V I C E
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

inch.

There are two nose assemblies available for the 07391 tool with only the nose tip varying. See nose assembly component table below
for part numbers. If you have purchased a complete tool, it will be fitted with one of these two nose assemblies.
It is essential that the correct nose tip is fitted prior to operating the tool. One or two extra nose tips are supplied screwed into the base
of the tool. For nose tip part numbers refer to the table on page 5. It is essential to use whichever nose tip has the smallest diameter
hole fitting over the fastener stem.
FITTING INSTRUCTIONS
I M P O R T A N T
The air supply must be disconnected when fitting or removing nose assemblies unless specifically instructed otherwise.
Lightly coat the jaws with Moly lithium grease.
Drop jaws 4into jaw housing 3.
Insert jaw spreader 5into jaw housing 3(locating in the ‘V’ shape formed by the jaws).
Locate buffer 6on jaw spreader 5.
Locate spring 7into jaw spreader 5.
Fit locking ring 8onto the jaw spreader housing assembly of the tool.
Holding tool pointing down, screw on the assembled jaw housing onto the jaw spreader housing assembly of tool and tighten with
spanner.
Screw nose tip 1into nose casing 2.
Place nose casing 2over jaw housing 3 and screw onto tool, tightening with spanner.
NOSE ASSEMBLY COMPONENTS
The table lists component part numbers for
both nose assemblies. Item numbers refer to
the text and illustration above. We recommend
some stock as items will need regular
replacement. Read nose assemblies servicing
instructions above carefully.
SERVICING INSTRUCTIONS
Nose assemblies should serviced at weekly intervals.
Remove the complete nose assembly using the reverse procedure to the ‘Fitting instructions’.
Any worn or damaged part should be replaced by a new part.
Particularly check wear on jaws.
Check spring 7is not distorted.
Assemble according to fitting instructions.

Regular servicing should be carried out and a comprehensive inspection performed annually or every 500000 cycles, whichever is
sooner.
I M P O R T A N T
The employer is responsible for ensuring that tool maintenance instructions are given to the appropriate personnel.
The operator should not be involved in maintenance or repair of the tool unless properly trained.
D A I L Y
Daily, before use or when first putting the tool into service, pour a few drops of clean, light lubricating oil into the air inlet of the
tool if no lubricator is fitted on air supply. If the tool is in continuous use, the air hose should be disconnected from the main air
supply and the tool lubricated every two to three hours.
Check for air leaks. If damaged, hoses and couplings should be replaced by new items.
If there is no filter on the pressure regulator, bleed the air line to clear it of accumulated dirt or water before connecting the air
hose to the tool. If there is a filter, drain it.
Check that the nose equipment is correct.
Check the stroke of the tool meets the minimum specification (inside front page). It is the difference in the measurement between
the front face of the jaw spreader housing assembly and the front face of the handle top bore before the trigger is operated and
once it is fully pressed.
W E E K L Y
Dismantle and clean the nose assembly with special attention to the jaws. Lubricate with Moly lithium grease before assembling.
Check for oil leaks and air leaks in the air supply hose and fittings.
Grease can be ordered as a single item, the part number is shown in the service kit overleaf.
SE R V I C I N G T H E T O O L
FIRST AID
SKIN: As the grease is completely water resistant it is best
removed with an approved emulsifying skin cleaner.
INGESTION: Make the individual drink 30ml Milk of
Magnesia, preferably in a cup of milk.
EYES: Irritant but not harmful. Irrigate with water and
seek medical attention.
ENVIRONMENT
Scrape up for burning or disposal on approved site.
M O L Y L I T H I U M G R E A S E E P 3 7 5 3 S A F E T Y D A T A
FIRE
FLASH POINT: Above 220°C.
Not classified as flammable.
Suitable extinguishing media: CO2, Halon or water spray
if applied by an experienced operator.
HANDLING
Use barrier cream or oil resistant gloves
STORAGE
Away from heat and oxidising agent.

For all servicing we recommend the use of the service kit below (part number 07900-03400) supplied in its own plastic case.
M A I N T E N A N C E
Every 500000 cycles the tool should be completely dismantled and new components should be used where worn, damaged or
recommended. All ‘O’ rings and seals should be renewed and lubricated with Moly Lithium grease EP 3753 before assembling.
I M P O R T A N T
Safety Instructions appear on pages 2 & 3.
The employer is responsible for ensuring that tool maintenance instructions are given to the appropriate personnel.
The operator should not be involved in maintenance or repair of the tool unless properly trained.
The airline must be disconnected before any servicing or dismantling is attempted unless specifically instructed otherwise.
It is recommended that any dismantling operation be carried out in clean conditions.
Item numbers in bold refer to the general assembly and parts list page 12 and 13.
Before proceeding with dismantling, empty the oil from the tool by removing handle plug 4and bonded seal 5. Empty oil into a suitable
container.
Prior to dismantling the tool it is necessary to remove the nose assembly. For simple removal instructions see the nose assemblies section, page 8.
For total tool servicing we advise that you proceed with dismantling of sub-assemblies in the order shown opposite.
