TyrFil Flushless Pump | Flatproofi ng Technical Manual
Note: Write the date and lot number on the bag and lay it on
the fl atproofed tire during the curing process. After the cure is
completed, the sample should be retained for future reference
should any problems arise while the fl atproofed tire is in
service.
10. Reset stroke counter to zero.
Processing
Important: Never leave a pump operating unattended.
1. Position tire vertically in the tire cage with the valve stem
between the 4 o’clock and 8 o’clock position, with 6 o’clock
being ideal.
2. Select the proper core holder and fi lling adapter for the
valve stem. To avoid leaks, make sure all gaskets are in
place and threaded connections are assembled with Tefl on
®
tape. Remember, tires with longer or angled valve stems will
take longer to fi ll because of the increased back pressure.
Whenever possible, use the largest valve stem available.
3. Remove the valve core from the tire that has been infl ated for
pre-stretching. It is important to keep the bead seated. Do
not let air bleed excessively. See page 13 for Bead Reseating
instructions.
4. Insert the valve core into the core holder and immediately
connect the fi lling adapter to the tire valve stem. Attach the
fi lling adapter to the fl uid gun.
5. Fully open the valve on the manifold and begin fi lling the tire.
6. Check the internal tire pressure frequently by closing the hand
valve on the manifold and opening the pressure gauge valve.
7. Continue pumping until the tire has enough pressure to keep
the bead seated or tube infl ated. To check the level of material
in the tire, tap the casing lightly with a hammer (unfi lled portion
will sound louder).
8. When the venting pressure is reached, close the manifold hand
valve. Insert a hypodermic needle into a tread groove at the
12 o’clock position just deep enough to vent trapped air. Stop
inserting further when you start to hear air escape from the tire.
For steel belted tires and thick casings (greater than 12 ply) you
will need to drill a
1
⁄
8
-inch hole through the tire to assist needle
insertion.
9. Use of Carlisle TyrFil’s specially designed SmartNeedle
™
Inserter will make needle insertion much easier, safer, and will
avoid damaging the needle or your hand.
Note: After insertion of the needle, the tire pressure will drop. It is necessary to maintain at least 30%
until all of the air is completely vented and the tire is full of fl atproofi ng material.
