FIELD SET UP AND OPERATION
BEFORE operating your new CADMAN TRAVELLER , inspect the machine for any
damage or parts which may have come loose during shipping. REPORT ANY DAMAGE TO
YOUR DEALER IMMEDIATELY !
1. Tow the machine to the field. Park the traveller on the head land (lane way) at right angles
to the rows to be irrigated.
NOTE : For the first use of a new machine or a machine which has been drained prior to stor-
age, start in an area which will allow you to pull out the full length of hose (
EXCEPT
for one full coil ). This will allow you to be sure that the hose is properly laid on the
base layer and properly indexed.
If you are unable to pull out all of the hose in the area you are working, pull out enough
hose to reach the base layer. This will allow you to see if the coils of hose in the base layer are
stacked tightly together. If the hose is found to be improperly indexed (the hose tries to climb
up on itself or gaps exist between the coils of hose), do the following:
• Set the hose drum so that the hose connection is at the six o’clock position (closest
to the ground).
• Fully apply the brake to prevent further rotation of the hose drum.
• Manually move the coils of hose so that they are tightly stacked together all across
the base layer of hose.
Check the position of the hose guide in relation to the hose. If the hose does not travel
straight through the hose guide and lay snugly against the drum elbow, do the following (see
following page):
• Remove the indexer shield.
• Remove the # 50 chain which runs from the hose drum axle to the indexer gearbox.
•
Manually adjust the hose guide position so that the hose travels in a straight line
through the hose guide and lays snuggly against the drum elbow.
• Re-install the # 50 chain from the hose drum axle to the indexer gearbox.
• Re-install the indexer shield.
CAUTION
Before moving a traveller at any time, be sure that the drive system is fully engaged,
the engine fuel valve is in the OFF position and the transport brake is fully applied.
CAUTION
Low pressure operation can cause indexing problems. The hose indexing sys-
tem of your Cadman traveller is set up to properly index the polyethylene hose onto the
hose drum under most operating conditions. However, when operating at very low in-
let pressures (110 PSI or less), the PE hose can flatten slightly causing the indexing
system to appear to be either out of adjustment or not functioning properly. This is
probably not the case in this circumstance.
It is advisable to increase the inlet pressure at the machine to at least 110 PSI to
help prevent further hose indexing problems related to low inlet pressures.
