6. ADDING OIL

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 be reduced and
fasteners are not fully placed by one operation of the trigger.
All operations should be carried out on a clean bench, with clean hands in a clean area.
Ensure that the oil is perfectly clean and free from air bubbles.
Care MUST be taken at all times, to ensure that no foreign matter enters the tool, or serious
The tool must remain on its side throughout the priming sequence.
• Place tool on its side, oil plug 42 side up.
• Pull back stroke set finger 88 and unscrew rear casing 86 by a maximum of 5 turns from the fully 'IN'
position.
• With an Allen key, unscrew oil plug 42 and remove with oil seal washer 43.
• Fill tool with priming oil rocking gently to expel air.
• Replace oil seal washer 43 and oil plug 42 and tighten.
• You must now bleed the tool. This operation is to ensure air bubbles are eliminated from the oil
circuit.
• Release the trigger.
• Using an Allen Key open oil plug 42.
• Top-up with priming oil to reset level. Replace oil seal washer 43 and oil plug 42 and fully tighten.
• It is necessary to fit the appropriate nose equipment and adjust the tool stroke prior to operating the
tool
