For options with a foot shell:
Do not allow aggregates such as sand to remain in the foot shell. Upon exposure to aggregates, immediately disassemble
prosthesis by removing the foot shell from the foot and rinse with water. The abrasive properties of aggregates will wear the
fiberglass components of the foot module.
After use in water:
•
Remove the foot shell and take off the sock
•
Rinse the foot with clean water
•
Dry well
Replace sock and/or foot shell if worn to prevent damage to the fiberglass components.
The RUSH FOOT EVAQ8 Collection components may need periodic cleaning or replacement during the life cycle of the system and are
not replaceable under the warranty as it is considered normal wear:
•
Tubing
•
Inline filter
•
One-way valves housed inside the vacuum heel
B. Periodic Inspection of the RUSH ROGUE 2 EVAQ8 System:
• Inspect the foot module every six months. If the user is more active, more frequent inspection may be necessary. Service as
necessary.
• Visually inspect the tubing for kinks, cracks, or wear that may leak air into the system. Replace tubing if any of these conditions
exist.
• Remove the inline filter from tubing and look through it. If light can be seen, the filter is clean. If light is blocked, blast air from a
syringe through the inline filter from distal to proximal end (reverse of normal flow) to attempt to clear the blockage. If blockage
persists, the filter needs to be replaced.
• The one-way valves contained in the vacuum heel may need to be cleaned and flushed with distilled water or isopropyl alcohol to
ensure proper function. This procedure should be done only by a qualified professional.
• To flush the one-way valves and vacuum heel:
1. Exhaust Assembly
2. Exhaust Filter
3. Large O-Ring
4. Valve Body Adapter
5. Small O-Ring
1.
Remove the vacuum hose from the user's socket keeping it attached to the EVAQ8 foot.
2.
Remove the EVAQ8 foot from the user's socket.
3.

to the (2) Exhaust Filter. NOTE: If (4) Valve Body Adapter does not remove with (2) Exhaust Filter, use a flat blade screwdriver
to remove it.
5.
Place the (4) Valve Body Adapter into a soft jaw vice or grip with soft face pliers and remove the (2) Exhaust Filter with

7.
Inside the heel beneath where the (7) Straight Barb was located is another (8) Duckbill Valve. Remove the (8) Duckbill Valve
by tapping the foot against your hand or by straightening out a (9) Paperclip and inserting it into the other side of the heel
to push out the (8) Duckbill Valve.
8.
Inspect both (3 & 5) O-rings on the (4) Valve Body Adapter. There is one at the base of the threads, and one in a groove on
the body. Replace both if they show any wear.
9.
Clean the female threads in both sides of the heel with a cotton swab and isopropyl alcohol or distilled water.
10. If you are reusing the (1) Exhaust Filter, (7) Straight Barb, in-line filter, and (8) Duckbill Valve, clean them with isopropyl
alcohol or distilled water. Take extra care and make sure the (8) Duckbill Valve are clean and free from debris (a magnifier is
helpful for inspection). Flush the in-line filter from both directions to ensure it is clean.
11. Once the parts are dry, or if you are using new parts from a rebuild kit, set all the parts out on a clean surface.
12. Insert the turquoise (8) Duckbill Valve into the threaded opening of the (1) Exhaust Filter so that the (8) Duckbill Valve rim is
flush against the opening of the (1) Exhaust Filter and the tip of the (8) Duckbill Valve is inside the (1) Exhaust Filter. Thread
the (1) Exhaust Filter into the (4) Valve Body Adapter BY HAND until snug.
13. BY HAND, thread the assembled (1) Exhaust Assembly into side of the heel that will NOT be connected to the prosthetic
socket by vacuum hose.
14. Once the (1) Exhaust Assembly is threaded in snugly BY HAND, torque to 15 in-lbs. Do not over torque. Over torquing will
snap the threads and will not be covered under warranty. NOTE: If you do not have a torque wrench, thread the (1) Exhaust
Assembly until you feel a hard stop and then turn
