7 Move the plunger carrier loop down and tighten the plunger screw until it 
stops.
8 Move the plunger carrier loop up and down. If the syringe plunger does not 
move along with the carrier, repeat the previous steps. Be sure the plunger 
screw is tight.

the slide up and down. The needle should slide smoothly in the needle 
guide. See Figure 42.
