MAINTENANCE
Poly Hose Repair
Hoses should be repaired as soon as possible after
damage is discovered to prevent further deteriora-
tion.
NOTE
• Pin holes in the hose should be marked with
a quick burst of bright colored spray paint
while there is pressure in the line to assist in
locating the hole later for repair.
Large tears or cuts, that interrupt operation, can be
temporarily repaired by using a rigid mender. A rigid
mender is a straight steel nipple that fits inside the
two hose ends to be joined. Clamps secure the hoses
to the nipple. Although rigid menders satisfactorily
join the sections, they do introduce a rigid section in
the hose which encumbers free travel of the hose on
the cart path.
Permanent hose repairs require special equipment.
Contact your Valley Dealer for permanent repair of
hose or training and use of the special equipment.
Rigid Mender Installation
1. Place the rigid mender between the two sections
of hose. See Figure 80-1.
2. Insert the mender halfway into the first hose sec-
tion. See Figure 80-1.
3. Slide the other hose section into the mender.
See Figure 80-1.
4. Secure both hoses onto rigid mender with band
clamps. See Figure 80-1.
Flex Joint Hose Replacement
No extra support is needed when changing the flex
joint hose. See Figure 80-2.
1. Loosen the band clamps and slide out of way.
2. Remove the old flex joint hose.
3. Insert the new flex joint hose.
4. Position the band clamps and tighten completely.
NOTE
• Position the band clamps so that they do not
interfere with the alignment mechanism.
