10.0 OPERATION INSTRUCTION.
We shall now go through a complete wrapping process, from loading to storage place, and explain
the practical use of Auto Wrap 1200 EH.
10.1
LOADING.
Pick a bale to wrap. Increase the opening between the rollers as much as possible. Lower the
machine almost to the ground.
Do not lower the machine all the way down to the ground.
Drive
in under the bale. Close the rollers until they begin to lift the bale. Lift the machine and the bale
approx. 4"-6", (10-15 cm), above the ground. Close the rollers completely.
The rollers must not
under any circumstances hit the ground while closing.
The reason why the rollers shall not hit
the ground is that this will increase the wearing on the gears and the bearings of the rollers.
10.2
HEIGHT ADJUSTMENT OF TOWER / PRESTRETCHER.
The tower is adjustable up or down after the bale size. It has three fixed adjustments. The tower and
the wrapping arm with prestretcher are rather heavy, so it is recommended to use a tackle or the
front loader to lift it. Tighten the properly after adjustment. The prestretcher has to be adjusted so
that the plastic film is always hitting the middle of the bale. If you use a 500 mm film on a 750 mm
prestretcher, the height of the film roll can also be adjusted with the two distance sleeves.
(See chapter 6.6).
10.3
START.
Remember that the plastic film end has to be locked in the U-shaped slot before starting the
wrapping. When the plastic film end is in the slot, push "
START
"
(8),
and the wrapping arm now
moves at ½ speed for approx. one half revolution before it automatically switches to full speed. This
is to avoid damage of the film when starting. When the wrapping arm has done a couple of
revolutions, the cutter-arm automatically releases the film end. (See also chapter 10.7).
10.4
OVERLAP.
Control that the overlap is correct. If not, see chapter 9.0.
10.5
HOW MANY LAYERS OF PLASTIC FILM?
When the bale is completely covered with film, read the counter that displays the number of
revolutions done by the wrapping arm. This number has to be multiplied by 2 or 3, depending on how
many layers of film you want to have.
* 4 layers - multiply by 2.
* 6 layers - multiply by 3.
As long as you wrap bales with the same diameter, you can stop at the same number every time.
10.6
STOP.
When the required number of revolutions is obtained, push the"
STOP
"-button
(9)
. The wrapping arm
will now rotate 1-2 revolutions, the cutter moves up, the arm speed is reduced and it stops at the
right place for next wrapping cycles. Then the cutter is closing automatically, and the film is held
tight in the U-formed slot and perforated. The bale is now completely wrapped and ready for
stacking.
10.7
When the wrapping sequence is ended, give the
ZERO-
button
(3)
a
short
push, and
a stroke
lights
up in the display. The stop-value is now stored in the memory, and the wrapping arm will
automatically stop after the same number of revolutions by the next wrapping sequence. (The stroke
will extinguish after the first revolution in next wrapping sequence).
* Emergency stop: see chapter 2.1
