TyrFil Flushless Pump

| Flatproofi ng Technical Manual

15. Lay the sample on the fi lled tire for use in checking the

progress of the cure. Use a tire marker to identify stroke or
weight count and psi on the tire. Document in the fl atproofi ng
log. This log is used to record processing data and customer
warranty information.

Note: It is very important to keep accurate records as this
ensures adequate warranty documentation in the unlikely
event that the need arises. In the Flatproofi ng Log, you should
include: date of processing, customer name, pumper’s name,
type of tire, product used, lot #, fi nal tire pressure and pounds
of material. All entries should be in ink and a copy should be
made of each entry sheet. Flatproofi ng log sheets are available
through Carlisle TyrFil for your convenience.

16. Put rim stickers on the wheel.

Note: Warmth speeds the cure. Tires fl atproofed with materials
at 72˚ F (22˚ C) and placed in a warm room [minimum 72˚ F (22˚
C)] will cure 70% in 24 hours and 100% in 72 hours. Tires can
go into service 24-48 hours after processing.

Tire Pressurization

Over-pressurization -

Do not over-pressurize tires. In addition to the potential danger of bursting the tire,

over-pressurization will cause “crowning” (extreme tread wear at the center of the tire) and possible splitting
of the carcass upon impacting curbs, potholes, etc. Once the material has cured, there is no way to correct
this problem. If a tire becomes over-pressurized during the fi lling process, close the manifold valve and open
the drain valve. Pressure inside the tire will force the fl atproofi ng material out through the drain valve. Close
the drain valve and check pressure again.

Under-pressurization -

Do not under-pressurize the tire. This can cause excessive fl exing of the casing and

material, which may lead to overheating and eventual tire failure. Unlike a tire fi lled with air, a complete loss of
pressure can result from the leakage of only a small amount of material from the tire after it is fi lled. If leakage
is observed, the tire may need to be re-pressurized.

Re-pressurization -

Voids or air pockets are created when uncured material escapes from a newly

fl atproofed tire. Once the fl atproofi ng material has cured, a tire with voids can be re-pressurized by injecting
additional material through the sidewall. Contact the Carlisle TyrFil Technical Department prior to sidewall
injection.

Clean-Up Procedures

Proper shutdown and cleaning of the pump and equipment is vital. When you have fi nished processing tires,
the equipment must immediately be cleaned of all reactive materials. If left in the machine, they will cure,
become insoluble and clog the equipment.

1. Open the hand valve over a waste container until the pistons

are in the down position. This allows the piston rods to be
submerged in the throat seal lubricant. Then close the manifold
hand valve.

2. Turn off the air supply to the air motor by closing the ball valve

at the regulator.
