8.4 PRIMING PORTS
Fig. 5
8.5 STROKE SETTING
The Pull Stroke Setter is used to advance the Head Piston 64 to full stroke. The external threads on the Pull Stroke Setter
wind into the Head 63, pushing the Head Piston back. With the Head Piston fully forward, only one side of the Pull Stroke
Setter will wind into the Head, as the Head Piston prevents thread engagement when using the other side. When the Pull
Stroke Setter is wound up to a stop in the Head, the Head Piston has been advanced to half of the available stroke. The Pull
Stroke Setter is then unscrewed and the other side is wound into the Head, completing the stroke.
The Return Stroke Setter is used to draw the Head Piston 64 fully forward. The Return Stroke Setter stops against the Head
63, whilst the internal threads wind on to the Head Piston, drawing it forward. With the Head Piston at full stroke, only one
side of the Return Stroke Setter will wind on to the Head Piston, as the Head prevents thread engagement when using
the other side. When the Return Stroke Setter is wound up to a stop in the Head, the Head Piston has been returned to
approximately half of the available stroke. The Return Stroke Setter is then unscrewed and the other side is wound on to the
Head Piston, returning it to the fully forward position.
When either Setter is used, the Head Piston should not rotate. If necessary, a 10mm A/F Allen key should be fitted to the rear
of the Head Piston to prevent rotation. It may be necessary to move the Head Piston forward with the Starter Nut to allow
the Return Stroke Setter to engage the thread.
8.6 INITIAL PRIMING PROCEDURE
Follow these instructions if all of the oil has been emptied from the tool, e.g. following tool disassembly and maintenance. If
the tool has stroke loss, follow the Top-up Priming Procedure on page 26.
