Prepare to wrap
Do not wear loose-fitting clothing, which may catch in moving parts. Always wear
protective clothing and substantial shoes.
We strongly recommend that you make certain that there is no non implicated people on
the wrapping site. This is particularly important for the owner of an automatic model
operated from the tractor. Never let the machine operated without superintendence.
Before starting to work with your Stretch-O-Matic ® , we strongly suggested tha
you:
 Carefully study and understand this manual.
 Give the unit a visual inspection for any loose bolts, worn parts or cracked welds, and
make the necessary repairs.
Follow the maintenance safety instructions included in this manual.

children and animals.
 Because it is possible that this equipment may be used in dry areas or in presence of
combustibles, special care should be taken to prevent fires and fire-fighting
equipment should be readily available.
Instructions before towing your Stretch-O-Matic ®
It is possible to tow your bale wrapper but the recommended maximum speed is 40
kilometer per hour. And, certain precautions allow to avoid disastrous situations.
Therefore we recommend that you :
 Check that the roller table is safely locked into the upward position with the bar
locked into place with both pins.
 Check that the draw pole is safely locked with the hitch pin locked into place.
 Attach a safety chain to the draw pole if the unit is to be towed on public road.
 Check that the wheels are straight.
 Close the steering cylinder’s valve to lock wheels.
 Comply with state and local laws governing highway safety and movement of
farm machinery on public roads.
 Use approved accessories, lighting, flags and necessary warning device to
protect operators of other vehicles on public roads during daytime and nighttime
transport. Various safety lights and devices are available from your local dealer.

Plastic Installation
For security reason, the motor will be stop when you open the side door to install the
plastic roller, ( photo #3 p. 11)
Need to reset to restart (reset button picture #5 p.17)
The plastic must be treaded over the slave roller and then through the two red rollers on
the tensionner as shown on the diagram.
The two black stretcher rollers rotate at different speeds. This induce the plastic to be
stretched. It is very important that the plastic go over the slow roller first and the faster
roller second. The faster roller should be marked by a red dot opposite it on gear case.
If there is any question of which is the fast roller (For the serial numbers up to 345.)
1) Place a pen mark on each roller and rotate one roller one turn.
2) Check the location of the marks on the other roller.
● If it has advanced further then, it is the fast roller.
● If it has advanced less, it is the slow roller.
When the plastic is installed properly, it should stretch film tight on the bale to form a
smooth linear tube.

Making Silage
Bale quality
Well shaped firm bales are necessary for successful wrapping.
Bales are best wrapped as soon as possible after baling.
If bales are left unwrapped they will sag and lose shape.
Heating will start soon after baling and the protein quality will be lost. It is desirable to
wrap within four hours of bailing.
The Stretch-O-Matic ® can operate even under rainy condition.
Moisture
There is a considerable moisture range over which successful silage can be made.
In general, 40 to 50 % moisture is satisfactory for dairy cows. Some beef farmers prefer
60 to 70 % moisture as it limits intake. A good rule of thumb is «Half way to Hay».
The ideal being 55% moisture.
Dryer silage gives you :
1. ighter bales to handle
2. ess freezing in the winter
Wrapping dry hay or straw
The Stretch-O-Matic wrapper can be used to weather protect dry hay and straw.

Wrapping Site Recommendations
Select a site, which will allow for making adequate length rows of bales. The Stretch-O-
Matic ® is a very fast wrapper but requires time to set up and move to a new row. There
should be space for at least fifty bales in a row.
Select a site that is accessible all year round and which does not flood in the spring.
A firm surface is preferable for the successful operation of the Stretch-O-Matic ® . Wrap
on a level or up a slight grade. If you must wrap along a slope, optional guide wheels
are available.
A site that is free from grass and debris will be less likely to attract rodents that can
damage the plastic.
Marking lay-out for best efficiency
If bales are brought to the site
before wrapping, arrange them
to allow easy access to bales
and allow the wrapper and tractor
plenty of room to move.
Note : initially takes 3 to 4 bales
before bale wrapper moves.
A guide bale is first placed
on the machine to protect
the end of the line.
Once the row is well under way,
it is picked up.

Recommended Operating Procedure
WARNING !
Always switch engine off and remove ignition key
before installing or changing plastic rolls, doing maintenance or
climbing on the wrapper.
We suggest the following method
of operating the Stretch-O-Matic ® models 7500 & 8400
Manual and automatic models first steps
• Park the wrapper where you want the end of the row, facing in the right way.
• ower the wrapper to the ground using the draw pole jack. Remove the jack.
If your wrapper has hydraulic front wheel, use the up/down lever to lower the machine.
Be certain that the forward-backward lever is in the « FLOATING POSITION »
before starting to wrap bales.
• Attach the chain from the folding roller table to the bale pusher with the bale pusher in
the open position.
• Stop the motor before installing plastic rolls. Open security guards, install plastic rolls
according to diagram on page 9 in this manual. Properly close the security guards
before starting the engine.
• Remove the transport lock bar.
• Open the steering lock valve.
Manual model (Automatic model see next page)
 Use the bale pusher valve to close bale pusher, lowering roller table.
 Install roll of plastic according to Plastic installation diagram on page 9.
 Open bale pusher and place the first guide bale on the table. Push this bale through
the hoop. This gives a stable end for the line. This bale is picked up and placed on
the wrapper later when the line is well under way.
 Next, place a single bagged bale on the wrapper and push it to the hoop to form the
end seal. Alternatively a bale of straw or a special plastic cap can be used to form a
tight end seal.
 From the outside, pull out some plastic through the stretcher closest to you and tie it
to the stabilization bar of the fix hoop. Push hoop lever forward to apply one and a
half layer of plastic. Untie plastic and repeat with the other plastic roll.
 As the bale is pushed through the hoop, start the plastic dispenser rotating to apply
plastic. Keep your plastic overlapping six inches, this will apply four layers. By
adjusting the flow divider you will control the speed of the rotating hoop, thus
controlling how many layers of plastic is applied on the bales.
 We recommend an extra layer of plastic on this first joint. This will compensate for
the stress when the first bale touches the ground. The same recommendation is
valid for the last joint of your line.

Apr-17

Automatic model
 Start the engine, make certain it is free of hay or combustible material.
 Start as recommended at top of page above and after starting the engine put the
machine in manual mode.
 Press forward button to close bale pusher, lowering roller table then install roll of
plastic according to the Plastic Installation iagram on page 12.
 Open bale pusher and place the first guide bale on the table. Push this bale through
the hoop. This gives a stable end for the line. This bale is picked up and placed on
the wrapper later when the line is well under way.
 Next, place a single bagged bale on the wrapper and push it to the hoop to form the
end seal. Alternatively a bale of straw or a special plastic cap can be used to form a
tight end seal.
 Pull out some plastic through the stretcher closest to you and tie it to the stabilization
bar of the fix hoop. Push on hoop button to apply one and a half layer of plastic.
Untie plastic and repeat with the other plastic roll.
 As the bale is pushed through the hoop, start the plastic dispenser rotating to apply
plastic. Keep your plastic overlapping six inches, this will apply four layers. By
adjusting the flow divider you will control the speed of the rotating hoop, thus
controlling how many layers of plastic is applied on the bales.
 We recommend an extra layer of plastic on this first joint. This will compensate for
the stress when the first bale touches the ground. The same recommendation is valid
for the last joint of your line.
 After enough bales have been wrapped manually for the machine to start moving
forward, it is put on the automatic mode.

When the operator press the RED button, the wrapping system stop.the
operator need to press the reset on the control box and star. If the operation
is STOP is press during the wrapping, it suggested to put the swith in
manual mode and finish the bale manually after put back in automatic form
and restart the processus automatic- reset- start

Apr-17

 The photocell located on the bale cradle is activated when the bale is placed on the
wrapper. This switch starts the bale pusher (ram) moving the bale towards the hoop.
 The moment the bale pusher (ram) hits the second limit switch should correspond to
the front of the bale entering the hoop. This switch will signal the hoop to start
wrapping.
 When the pusher has fully advanced, it hits the third limit switch. This one will signal
the hoop to stop turning and the ram to retract.
 As the ram retracts fully it will hit the first limit switch which will signal it to stop and
wait for the next bale.
CAUTION !
Before switching engine off, always have the machine in « MANUAL MODE »
and the electronic control panel switch should be moved in « OFF
POSITION ». The remote control is used only when the button on the
control box is in «Automatic mode». The operator must keep in mind
that a visitor might not realize that he is operating with the remote control.
Always keep a safe distance from the moving parts.

Plastic Application
Careful application of an adequate amount of plastic is critical to gives good quality
product. Careless application of plastic will result in losses.
Continually watch for «dark windows» indicating that not enough plastic has been
applied.
• You can adjust the sliding limit switches positions to get a customized plastic
application.
The 1
st
limit switch gives the ram its starting position.
The 2
nd
limit switch gives the hoop its starting command.
The 3
rd
limit switch gives the ram its retracting signal and the hoop its stop signal.
By changing the position of the limit switches 2 and 3, it is possible to automatically apply
extra plastic layers on bale joints. You also can change the position of the limit switches
when your bale length varies, thus you are not wasting any time or plastic.
• Use steering valve to keep row straight if necessary or « LEFT / RIG T » buttons on
automatic models.
• When the desired length of row has been reached, place a bale bag or cap on the
last bale to seal the end.
To Unload the Rolls
A special bar is provided for the unloading. She is placed on the right side of the machine.
• Insert the end of the bar in the pusher and attach the plate.
• Advance the pusher while finishing covering the last bale with plastic.
• Repeat this operation until the bale is fully at the end of the table with rollers.
• Put the bar back at it’s place.
• Using the chain fixed at the back of the frame, remove the machine from the line of the
bales, so you can put the tow bar. Or, if your wrapper is equipped with a traction, use the
proper lever to move it.
• Do the opposite than the starting motion, raise the table, attach it with the locking bar for
transport and install the hitch.
