14.1.3 Dispensing Head Piston Assembly:
Insert the lubricated piston into the dispense head. This motion should be
quite free and without too much force. If the piston does not move freely, a
little more Lubricant is required.
In that case, remove the piston, add a little more lubricant as prescribed
above and re-insert.
