| 1. |
The air supply must always pass through a filter, a lubricator and a pressure regulator. |
 |
| 2. |
The air pressure must be set to the value indicated in Table 1. NOTE: Failure to observe this instruction can result in serious damage to the tool. |
|
| 3. |
The tool should be operated without an insert until familiarity is achieved in the actuation of the two control features. |
|
| |
(a) |
Depression of the lever causes the mandrel to advance out of the tool. |
|
| |
(b) |
Depression of the button (with the lever still depressed) causes the mandrel to reverse into the tool. This will not happen unless the tool is under actual installation conditions. Under non-installation conditions the end of the threaded mandrel should be lightly pressed against a piece of smooth wood with the lever and button depressed, to return the mandrel into the tool. |
|
| 4. |
To install an insert: |
|
| |
(a) |
Depress both lever and button causing the mandrel to reverse into the tool leaving the chamber in the prewinder clear. |
|
| |
(b) |
Place an insert in the chamber with the tang end lying towards the nozzle end of the prewinder. |
|
| |
(c) |
Offer the nose of the prewinder up to the tapped hole in the workpiece making sure that the tool is in true alignment with and concentric with the hole. A light contact pressure should be applied and maintained between tool and workpiece from this stage through to the complete withdrawal of the mandrel from the installed insert. |
|
| |
(d) |
Release button but maintain depression on the lever. Allow mandrel to advance slowly into the insert until the driving end of the mandrel engages the tang of the insert and until the first coils of the insert are engaged in the first threads of the prewinder nozzle. The rate at which the mandrel advances can be controlled by sensitive manipulation of the button. |
|
| |
(e) |
Hold this condition and the insert will pass through the prewinder nozzle and into the workpiece. When the insert is installed to the correct depth the drive will stall or if the tool is one which is fitted with clutch, a clicking sound will be heard. |
|
| |
|
During the reversing process DO NOT attempt to pull the tool away from the workpiece until it can be seen that the threaded mandrel is disengaged from the installed insert. |
|
| 5. |
Depth of installation of insert: |
|
| |
(a) |
Having installed the insert one can judge whether it is too deep, just right or too shallow. This will be influenced by whether there is a countersink at the mouth of the hole and how deep it is etc. |
|
| |
(b) |
If the installation is too shallow remove a shim or shims from the spacer set and try again. |
|
| |
(c) |
If the installation is too deep add a shim or shims to the spacer set. Spare additional shims are supplied for this purpose. |
