Installation
The EN-Tree P must be installed in such a way that its use is not limited by other objects. Keep at least
2.50 m free around the unit.
The EN-Tree P must be attached to the wall with suitable fittings. The EN-Tree P must only be
mounted on a brick or concrete wall. Position the plugs firmly in the centre of a brick in case of a brick
wall. The fixation must be able to resist a horizontal pulling force of 950 N.
In case of installation of 2 EN-Tree P pulley, we advise you to place the centre of the EN-Tree P at
2.5 m from both sides of the corner (figure 1).

Warnings
Should the use of this device lead to an undesirable event such as death or serious injury to the
user, the manufacturer and the competent authority of the Member State MUST be informed
without delay!
Always use the original Enraf-Nonius accessories that are meant for this product.
The EN-Tree P should be operated or used by one person at once.
Limbs must be kept clear from moving parts.
Clean the cuffs after usage.
During exercising hands must be kept clear from the guiding bars of the weights.
Never re-set weights during exercising.
Do not change the load settings during exercising or training: load changes are only allowed in
the starting position
Avoid the cord grating along sharp paths.
Keep spectators away from the pulley when it is in use (at least 1 meter).
For safety reasons keep sufficient distance from a unit used for training; one should not be
within 1 meter distance from the outer borders of a unit while it’s used for training
When using the latissimus grip, first the load must be selected, before the grip is mounted. If
you change the weight in the meantime you have to hold the upperweight to prevent the grip
from falling down.
The 45 degrees Pull Down accessory is only intended for support during exercising. Never apply
the full body weight to the Pull Down accessory. The maximum admissible weight for the 45
degrees Pull Down accessory is 50 kilograms.
When used by children, supervision by a knowledgeable (para)medic is obligatory. At all times
keep children away from the equipment when no supervision is at hand!
A correct bio mechanical positioning of the body is necessary.
When the EN-Tree Pulley is not used in the correct way, injury may occur. Supervision by a
knowledgeable paramedic is therefore obligatory.
If pain is experienced during use: stop the training immediately and consult professional
medical help
In case of damage from transport is noticed, contact your local distributor.
DO NOT USE the device!
Caution
EN-Tree P is powered by low voltage currency, the pneumatic resistance is fed by compressed
air. Use only Enraf-Nonius supplied or prescribed spare parts. A wrong currency or a wrong
pressure can result in damage of the unit.
The manufacturer of the compressor advises frequent maintenance and the use of special oil
lubricants. To prevent malfunction follow the instructions in the service manual of the
compressor.
Take care to prevent the compression of electrical circuits wires and air tubes between the
moving parts and the unit itself.
The device is not intended for use in so-called "wet rooms" (hydrotherapy rooms).
Note
• In case of any malfunction of your EN-Tree P contact your Enraf-Nonius supplier or Enraf-Nonius
B.V. (Rotterdam, The Netherlands). Have repairs, maintenance and installations carried out by an
authorized Enraf-Nonius service technician
• Repairs or maintenance performed by a non Enraf-Nonius authorized service technician and/or
the use of (spare) parts that are not originally Enraf-Nnius made, results in a direct loss of any
guarantee
• The maximum resistance setting for the training equipment will be dependent on the pressure of
the compressor

8 Operation
Switch on
After switching on the device, a welcome screen will be displayed while the device performs a self-test.
At the end of the self-test the device enters the “stand-by screen” and is ready for use.
Training screen
This screen will show the amount of resistance
in kilograms (kg).
Default value is 5 kg.
The arch above the value indicates that it can
be adjusted by using the rotary knob.
When adjusting the resistance, the device will
tell you to wait until the right amount of force
is set.
The bottom half of the screen will show the
amount of repetitions or the time. Default
setting is zero (-) repetitions.
When the training is started, the device will
count the repetitions made.
Touch the field where the number of
repetitions is displayed to set a number
of repetitions.
Now the device will count down when
making repetitions.
Page 10 of 16 EN109-1400755-48 IFU
Press the clock button if you want to exercise
for a certain amount of time. Use the rotary
knob to set. Time will count down after the
first repetition. (Time will keep counting down,
regardless of the number of repetitions
made.)
When time is up or repetitions counted down
to zero, a beep will sound to indicate work out
is finished.
Series
Press the right tab if you want to
program a training with multiple series.
This can be either series of repetitions or
series of a certain duration.
Simply touch the parameters to adjust
them (the arch will appear to indicate
they can be adjusted with the rotary
knob).
Rest time will automatically start
counting down when a series is
completed. When the rest is over,
training will start when you start moving
again.
If you don`t want to complete a series or
pause, you can use the NEXT button to go to
the next phase.
Use reset to skip the entire training. The
device will return to default settings.
Programmed values will be lost.
Page 11 of 16 EN109-1400755-48 IFU
Record
A bar at the bottom of the screen will
display the range of motion (ROM).
Touch this area to set markers for the
right ROM, start and finish for the
movements.
A screen will open to record two
correctly executed repetitions.
On the bottom of the screen select if you want
to record both ROM and speed or just ROM.
Perform two repetitions. Limits for ROM (and
speed) will be recorded to be used as an
example for the next training session.
Few seconds after the recording is finished,
the EN-Dynamic will return to the training
screen.
Limits for ROM are now shown on the ROM-
bar. Moving outside this ROM will be shown
in red to indicate the movement is not
executed like recorded.
If speed is recorded as well, the speed
bar will show a “ghost” to indicate the
required speed.
If you want to change the ROM or
speed, just press the area with the bars
to start a new recording.
Reset will delete all set parameters for
your training including ROM and speed.
Page 12 of 16 EN109-1400755-48 IFU
Chip card
To execute a training programmed on an EN-
Train or Track chipcard, simply put the card
into the opening at the top of the console
(chip facing down and towards you).
The device will show a welcome screen.
Press OK to start the training.
If the training is completed, a beep will sound
and the device will tell you where to go next
(next device or PC).
Remove chipcard.

9 Maintenance
Cleaning
• The steel undercarriage can be cleaned with a damp cloth and a (nonabrasive) liquid household
cleaner
Maintenance
• To keep the leather parts flexible, you can use leather fat.
• After some time, the sliding and turning parts could run less smoothly, because of pollution and
dehydration. You can re-grease the Pulley with ball bearings grease (which you can obtain at a
bicycle shop). If required, the guiding bars of the weights can be greased with a little oil.
• Check the cord and the cord fixations regularly for signs of wear. In case of excessive wear and
tear, the cord must be replaced and use of the EN-Tree Pulley is not recommended until the cord
has been replaced.
• In order to obtain spare parts, please contact your supplier.
• We recommend to have the EN-Tree P checked yearly by authorized personnel of Enraf-Nonius or
by its authorized distributor. The manufacturer will not be held responsible for the results of
maintenance or repairs by unauthorized persons!
Expected service lifetime
This device will remain suitable for its intended use as long as it is subjected to yearly maintenance by
a qualified service engineer as described in the service manual.
The service engineer will decide whether the device is suitable for use according to the specifications.
End of life
Your EN-Tree P contains materials which can be recycled and/or are noxious for the environment.
At the end of the duration of life, specialized concerns can take apart the EN-Tree P and sort out the
noxious materials and materials for recycling. By doing so you contribute to a better environment.
Please ensure that you are well informed of the local rules and regulations regarding
the removal of equipment and accessories.
