Safety Rules This instruction manual must be read with particular attention to the following safety rules, by any person installing, operating, or servicing this tool. 1 Do not use outside the design intent. 2 Do not use equipment with this tool/machine other than that recommended and supplied by Avdel UK Limited.

Intent of Use The 74201 hydro-pneumatic tool is designed for placing Avdel® threaded inserts and is ideal for batch or flow-line assembly in a wide variety of applications throughout all industries. The tool works on the principle of adjustment of the force rather than the stroke. The advantage lies in the fact that it is possible to place the same insert (of the specified tightening thickness) in materials of different thicknesses, after setting the tool for the greatest thickness.
Putting into Service Air Supply All tools are operated with compressed air at an optimum pressure of 5.5 bar. We recommend the use of pressure regulators and automatic cooling/filtering systems on the main air supply. These should be mounted within 3 metres of the tool (see diagram below) to ensure maximum tool life with minimum tool maintenance.
Nose Assemblies It is essential that the correct nose assembly is fitted prior to operating the tool. If you know the code for your complete, original tool, or the details of the fastening systems which are to be used, you will be able to order a new complete nose assembly using the selection tables on page 9. Fitting Instructions I M P O R TA N T The air supply must be disconnected when fitting or removing nose assemblies unless specifically instructed otherwise.
Nose Assemblies Selection Nose tips vary in shape according to the insert type. Each nose assembly represents a unique assembly of components which can be ordered individually. All nose assemblies also include a nose tip Lock Nut 2 (part number 07555-00901). Component numbers refer to the illustration on the opposite page. We recommend holding some stock of internal components as items will need regular replacement. Read the Nose Assemblies Servicing Instructions opposite carefully.
S e r v i c i n g t h e To o l Regular servicing should be carried out and a comprehensive inspection performed annually or every 500,000 cycles, whichever is sooner. I M P O R TA 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.
S e r v i c i n g t h e To o l Service Kit For all servicing we recommend the use of the Service Kit (part number 74200-99990) supplied in its own plastic case.
Maintenance Every 500,000 cycles the tool should be completely dismantled and components replaced where worn, damaged or when recommended. All ‘O’ rings and seals should be replaced with new ones and lubricated with Molykote® 55M grease before assembling. I M P O R TA N T Safety Instructions appear on page 4. The employer is responsible for ensuring that tool maintenance instructions are given to the appropriate personnel.
Maintenance D i f f e r e n t i a l Va l v e • • • • • Using special flat spanner* unscrew Adaptor Nut 58, withdraw and remove Spring 54 and ‘O’ Ring 55. Remove Threaded Pin 50 and Deflector 49. Using a spanner* remove Silencer 59 and nylon Washer 51. Push Valve Piston 57 out from its housing together with ‘O’ Rings 56, 53 and 52. Check ‘O’ Rings 56, 55, 53 and 52 for damage, Spring 54 for distortion and renew if required. • Assemble in reverse order of dismantling.

Priming Priming is ALWAYS necessary after the tool has been dismantled and prior to operating. It may also be necessary to restore the full stroke after considerable use, when the stroke may have been reduced and fasteners are not now being fully placed by one operation of the trigger. Oil Details The recommended oil for priming is Hyspin® VG32 available in 0.5l (part number 07992-00002) or one gallon containers (part number 07992-00006). Please see safety data below.
