1. Preventative Maintenance
Performing regular preventative maintenance through visual inspection and part replacement will help keep the
710Shark-US working at its full capacity. Failure to properly follow the recommended PM schedule may result in
uneven fills and most likely, damage to the injector head.
*IMPORTANT*
1) CLEAN THE MACHINE IMMEDIATELY FOLLOWING PRODUCTION. This is the single most important step which can be
taken to ensure the longest lifespan of the machine.
2) Always change the entire 10 x 10 grid of gaskets, o-rings, and/or needles to ensure proper sealing.
3) A change of ALL gaskets is required anytime the needle plate is removed from the injector head.

Removing the Injector Head for Maintenance
1. Removing the Injector Head
Make sure that the oil basin platform and injector head are both cool to the touch before attempting to remove the
injector head!
Tools Required:
o#4 Allen
o#5 Allen
oSmall adjustable crescent wrench
oNeedle change foam block
**Note: If the injector head is being removed for O-ring maintenance, make sure to adjust the fill volume
hard-stop to its lowest value (>3.0ml) and open the injection plates by press Oil Inject on the “Manual”
screen.
1. If an oil basin is installed, remove it at this time.
2. Gently push the needle change foam block on to the 10 x 10 grid of needles, enough so that it sticks.
3. Navigate to the “Manual” screen.
4. Press the Oil Basin button to bring the oil basin platform up to the needles. This will push the foam on
to the needles the rest of the way.
5. Use the adjustable crescent wrench to unscrew the thermocouple from the back of the injector head.
6. Remove the heating elements by gently pulling them free from the injector head.
7. Using the #4 Allen, remove the four screws which attach the injector head to the bottom of the 4 guide
posts.
8. Using the #5 Allen, remove the 3 screws which attach the injector head to the piston flange.
9. Stabilize the injector head with your hand and press the Oil Basin button to bring the oil basin platform
down. This will lower the injector head and make it safely accessible for removal.
Replacing O-rings and Gaskets
1. Gaskets
Tools Required:
