 +You can now fix the claw arms to the end piece with the last two paper fasteners. ​
 +
 +Align the holes in the ends of the claw arms with the holes in the end piece (making sure the plunger flange is fitted into the slot provided), push the split pins through and bend the legs down as before. Thus time making a tight fit is preferred.

 +===== Step 10: Operational tips =====
 +
 +When you have finished assembly, the claw arms will be wide apart. Pulling down on the syringe at the end of the handle will pull the end piece towards the handle, and bring the claw arms together.
 +
 +If things get stuck
 +  * check the pins that go through the slots in the yoke can move freely - the less binding here, the better.
 +  * after a while, the claw arms might not move as far as they should - this is a sign that a n air bubble has formed in the system. Unfortunately,​ the only way to fix this is to cut the zip ties, and remove the bubble. Sometimes this will mean disassembling and re-fill the tubing and syringes with water. The quicker you push the syringes, the more likely this will happen - slow and steady is best.
