The hydro-pneumatic 0764 type 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 07640 fitted with a stem catcher is the standard tool for which a pintail deflector option is available (see details on page 9). It
is also possible to order the base tool only (part number 07640-00200) which will not be fitted with a nose assembly.
The base tool part number for the other two tools of this type, the 07641 and 07642, is 07641-00200. Differences with the
07640-00200 are on the general assembly and parts lists pages 18 and 19.

All tools are operated with compressed air at an optimum pressure of 5.5 bar. We recommend the use of pressure regulators and
automaticoiling/filtering systems on themain air supply. Theseshould befitted within 3 metresof the tool (seediagrambelow) 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 or1/4inch.
Read servicing daily details page 14.

There are three types of nose assemblies which are used with the 0764 type of tooling and thus three models 07640, 07641and 07642.
If you have purchased a complete tool, it will already be fitted with the correct nose assembly for your fastener.
It is essential that the correct nose assembly is fitted prior to operating the tool. By knowing your original complete tool part number
or the details of the fastener to be placed, you will be able to order a new complete nose assembly using the selection tables pages
4, 5,6 and 7 according to the tool model you are using.
0 7 6 4 0 M O D E L
The 07640 tool always uses a fixed nose assembly. Nose assemblies and components vary according to the type of fastener being
placed (see dimensions ‘A’ & ‘B’ on pages 4 and 5). Check part numbers on component tables.
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 4 into jaw housing 3.
Insert jaw spreader 5 into jaw housing 3 (locating in the ‘V’ shape formed by the jaws).
Locate buffer 6 on jaw spreader 5.
Locate spring 7 onto jaw spreader 5.
Fit locking ring 8 onto the jaw spreader housing assembly of the tool.
Holding tool pointing down, screw on the assembled jaw housing or chuck collet onto the jaw spreader housing assembly and
tighten with spanner.
Screw nose tip 1 into nose casing 2.
Place nose casing 2 over jaw housing 3 screw onto tool, tightening with spanner.

As described on pages 6 and 7 the fitting of a straight swivel nose assembly to a 07641-00200 base tool will create a 07641 tool model
and the fitting of a right-angle swivel nose assembly to the same base tool will create a 07642 tool model. Because there are few
differences between the two nose assemblies, the fitting and servicing procedures are almost identical. Differences clearly refer to the
model they apply to.
FITTING INSTRUCTIONS
The following procedure will allow you to fit either of the swivel nose assemblies (as illustrated below) to the tool. If you order a complete
nose assembly rather than individual components, you will only need to start at stage .
Allmovingpartsshould be lubricated. Unless stated otherwise use Moly lithium grease (details page 14). When on grey tint, instructions
refer only to the right-angle nose assembly fitted to 07642 models.
Fit locking ring 10 over jaw spreader housing of tool (item 19 page 18).
Coat screw 13 with thread locking adhesive and use to secure nose tip 14 onto body 5.
Lightly lubricate items 17,18,19,20 and insert into jaw carrier 3 as shown. Secure with screws 16.
Position lever 4 into body 5 and hold in place with pin 15 through the hole of body 5 (not a slot).
Lubricate the sides of the jaw carrier assembly and insert into body 5.
Lubricate rollers 8 and ENSURE that they will freely rotate in the holes of adaptor 9. If necessary ream the holes.
Position spring clip 7 over adaptor 9 past the holes for the rollers and rotate until the locating peg is aligned with the corresponding
hole in adaptor 9(smallest hole).
Fit adaptor 9 over the end of body 5 and drop rollers 8 into place. Push spring clip 7 over rollers 8.
Insert spindle 11 through adaptor 9 into jaw carrier 3 until the hole lines up with slot in body 5. Temporarily hold in place with
pin 6.
Insert pin 12 through the front slot of body 5 into jaw carrier 3.
Hold the assembly vertical to prevent all pins dropping and slide the jaw carrier assembly back and forth a few times to ensure free
movement.
Push pin(s) 6 out and let spindle 11 drop out. Screw spindle 11 onto the jaw spreader housing of the tool, leaving the small screw
fixing hole uppermost for straight swivel nose assemblies. Tighten gently with a tommy bar.
Screw the assembly over spindle 11 onto the tool handle. Replace pin(s) 6.
On straight swivel nose assemblies attach platform 22 onto the top of the spindle with screw 21. Deburr the back end of platform
22 so that it cannot catch on guard 1.
Snap guard 1 over the assembly, carefully sliding cut-out around the head of screw 15 and secure with screw 2.

SERVICING INSTRUCTIONS
Nose assemblies should be serviced at weekly intervals.
Item numbers refer to both illustrations on page 12.
Remove the complete nose assembly using the reverse proce-
dure to the ‘Fitting instructions’.
If guard 1 is at all damaged it must be replaced by a new one.
Any worn or damaged parts should be replaced.
Pay particular attention to jaw carrier items in the upper
illustration opposite as follows:
Check wear on jaws 17.
Check that jaw spreader tube 18 is not distorted.
Check that spring 19 is neither broken nor distorted.
Check that spring guide 20 is not damaged.
Check that spring clip 7 is not distorted. When removing
spring clip 7, use two screwdrivers as shown in the lower
illustration opposite.
Check for excessive wear on slots of body 5.
Assemble according to fitting instructions.

CONSTANT COMPONENTS

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 pressing the trigger and when
it is fully depressed.
On 07640 model, if stem extraction is required, check and set stem extraction adjustment as follows:
Item numbers in bold refer to the general assembly and parts list page 18 and 19 .
With tool connected to compressed air supply, turn vacuum adjustment screw 11 clockwise until air flow from rear end of tool head
ceases. With nose of tool pointing downwards, insert a rivet into nose tip and hold in position. Turn vacuum adjustment screw anti-
clockwise until there is sufficient suction at nose tip to retain rivet. Fit stem catcher assembly and place rivet. If broken stem fails
to eject, then increase vacuum by turning vacuum adjustment screw anti-clockwise.
If stem extraction is not required, turn vacuum adjustment screw clockwise until air flow from rear end of tool head ceases. In this
mode, plunger of valve plug assembly 67 will remain extended, making tool unstable when standing. This can be overcome by
replacing valve plug assembly 67 with valve plug 69 .
Note: When using stem extraction, ensure nose tip is NOT fitted with a stem retention device.
Ensure either stem catcher or pin tail deflector are fitted as required.
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 opposite.

Safety Instructions appear on page 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 18 and 19 .
Before proceeding with dismantling, empty the oil from the tool. Remove 4 and bonded seal 5 from the handle assembly and drain the
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, pages
