Polyethylene Tube
Precauons for Handling
The polyethylene irrigaon tube is a durable product that will operate reliably for many years if handled
properly and given a reasonable amount of care.
Medium Density Polyethylene is a semi-rigid product that retains its shape when it is not pressurized but can
also be wound on a drum or spool without damage. This characterisc makes it feasible to pump uid through
it while it is rolled up on a reel.
A few simple precauons need to be observed to prevent damaging the tube when operang your Avi-
FoamGuard.
1. When starng a new Avi-FoamGuard for the rst me, you must pull the tube all the way out in order to
correctly ghten the new tube on the spool. It is also important to follow the ming instrucons on Page 8
of this manual and in the operaonal video that was provided with this manual. The Avi-FoamGuard must
be med on the rst run.
2. Never transport the Avi-FoamGuard with the an-return pawl in the up posion! The tubing will become
loose and tangled. Do not aempt to operate your Avi-FoamGuard if there are any coils of tube that are
loose or misplaced. If loose coils of tube are noced aer pulling the tube out, they must be ghtened by
rotang the spool with the pto hand wheel. If this is not possible, pull all of the tube out before
aempng to rewind the tube.
3. Never try to move or relocate the machine if the tube is not fully rewound onto the machine.
4. Never pull the tube o the machine other than by pulling on the foam cart (straight out from the machine).
5. Never run over the tube with any kind of vehicle and avoid pinching or pulling the tube around objects.
Never bend the tube sharper than 25 mes the inner diameter of the tube.
6. If the tube is frequently pulled out only a poron of its complete length the tube remaining on the drum
will become loose. Occasionally it will be necessary to pull all the tube o the drum, leaving only several
coils remaining on the drum, to ghten the remaining coils.
7. Be careful when operang other equipment near the tube. Make sure the tube doesn’t get gouged or
punctured.
8. Avoid rewinding the tube when it is not pressurized. When the tube is not pressurized during rewind the
tube will become aened or egg-shaped and the rewind mechanism will not funcon properly. Keep the
tube pressurized to 100 PSI when rewinding!
Remember, polyethylene tube is semi-rigid and subject to being crimped. The foregoing precauons will reduce the
possibility of kinking or damaging your tube.

Timing
Proper ming of the levelwind mechanism is essenal to the successful operaon of the Avi-FoamGuard. A machine
that is not in me will result in miswrapped tube. Timing is the coordinaon between the levelwind fork and the rota-
on of the spool or drum which allows for the ght and neat coiling of the tube on the reel of the unit.
Note: You must verify ming before the rst run of the Avi -
FoamGuard!
Verify Timing:
Step 1 - Make certain the trailer is secured with wheel chocks. Li the An-Reverse Pawl and slide the holding pin
under it to hold the pawl in place.
Step 2 - Pull the tube out 100%. This is
the only me you pull the tube out its
enre length. The elbow to which the
tube is fastened must be 45° behind the
axle center line on the boom of the
spool once the tube is completely pulled
out. Be especially careful not to pull the
tube o the elbow.
Step 3 - Remove the four bolts that hold
the levelwind fork in place and remove
the fork. Observe the posion of the
hose guide carrier drive lug (special hose
guide link) on the secondary chain. (The
chain that runs le to right just in back
of the auto shut o bar). The drive lug
should be in the most extreme posion (half way around the sprocket) and on the same side of the drum as the spool
elbow. When these condions are met, the machine should be in me and ready to wind in (See Fig. 1 below). Fig. 2
illustrates a machine that is not in me.
Machine Must Be Timed
on First Run!

Timing
Adusng Timing:
Step 1 - Remove the levelwind guard
Step 2 - Remove the 2 bolts on the levelwind input sprocket. Now you can manually adjust the levelwind mechanism by
grabbing the sprocket with a pair of channel locks, holding the sprocket sll and making adjustments unl you see the
drive lug in the correct posion. Once the drive lug is in the correct posion, your machine is in me.
Step 3 - Replace the Levelwind guard and then replace the fork, being especially careful not to have any over-hang on
the chain side of the mounng plate as shown below.

Remove Guard
Cauon! Over-hang on the chain side of the mounng plate when replacing
the fork will cause damage to the unit during operaon!
