--Start Up--
Caution! If the tube is pulled out in an arc, the first 20% of the tube must
be pulled straight away from the machine. Failure to observe this
limitation places excessive side load on the level wind mechanism and
may result in equipment failure or tube damage. See the section titled
“Handling The Polyethylene Tube”.
Use a gear in your tractor that will not exceed 3 MPH at full throttle. Pull the tube out
at a steady rate and do not exceed 3 MPH. Do not start and stop. Slow the tractor
to 1 MPH or less for fifty feet prior to stopping.
The purpose of the gearbox brake is to prevent coils of tube from becoming loose on
the tube spool. Loose coils of tube will make the level-wind mechanism appear to
be out of time. In this case, the level-wind system will be damaged and a mis-wrap
will occur.
Coasting of the spool during the tube pull out is the most frequent cause of mis-wrap
problems! This problem is most common when the Water-Reel is used often in short
runs and the entire tube is seldom pulled all the way out or when the sprinkler cart is
pulled out fast and with sudden stops. When the spool coasts, the irrigation tube will
become loose on the spool.
7. Adjust sprinkler cart to the desired width. See “Specification Section”.
8. Turn on the pump. Do not pick up or hold Supply Hose as it is being pressurized!
Confirm the sprinkler is operating as expected and in the desired arc. The arc of the
sprinkler will affect the precipitation application of the system. Note the “Precip Rate”
column on the performance guide located on the Water-Reel. The lowest
precipitation rate will occur when the sprinkler is operating a full 360-degree circle.
See below.
Note:
The swivel seal at the main bearing may leak initially at low pressure however
will stop as pressure increases, and the “o” ring seats.
Note: Arc settings where the sprinkler never throws
water forward of the sprinkler cart could make the
sprinkler cart track off line. This is caused by the
continuous thrust of the sprinkler that tries to push the
tube towards the Water-Reel. It is necessary to have
some sprinkler thrust which puts the Tube under
tension.
