Other
Preventive Maintenance
Other preventive maintenance
activities must be completed by a
qualified service technician at the
recommended intervals. Failure to
do so could result in serious
injury. These activities include:
• Flipping or replacing the
running deck.
• Replacing the running belt.
Static electricity: Depending on
where the treadmill is placed, you
may experience dry air, causing a
common experience of static
electricity. You can notice that by
walking across a carpet and then
touching a metal object. On your
treadmill you may experience a
shock due to the build-up of
static electricity on your body and
the discharge path of the tread-
mill. If you experience this type
of situation, you may want to
increase the humidity to a
comfortable level through the use
of a humidifier.
Maintenance must be performed on a regular basis. Performing maintenance actions can aid in providing
safe, trouble-free operation of all JLL equipment.
JLL is not responsible for performing regular inspection and maintenance actions for your machines.

Treadmill Cleaning
K
eep the running belt free of dust and debris
for smooth running and prevent injuries. They
could damage the electric motor and other
moving parts.
After every workout use a neat, dry cloth for
cleaning the treadmill and the handrails to prevent
the machine of corrosion. And wipe away any sweat
that may have dripped onto the running belt. Avoid
scratching the display by using a soft cloth and no pa-
per towel.
Contaminants, such as hand lotions, oils or body
powder, may come off on the heart rate sensors. These
can reduce sensitivity and interfere with the heart rate
signal. It is recommended that the user have clean
hands when using the contact heart rate. Clean the
handles using a cloth dampened with water.
For cleaning the console unplug the machine and
clean with a dust free cloth. For further cleaning, use
a soft cloth or paper towel damped with water. Do not
use abrasive or chemical cleaning agents.
3 easy steps to clean your treadmill:
1. Set the speed at 2 km/h and put a humid, clean
cloth at the end of the running belt, hold it there
and move it along the end of the running belt
until it is free of dust.
2. Vacuum or sweep the floor underneath and
around the treadmill to prevent that any speck
goes into the mechanism. A treadmill mat can
help to avoid dust goes into it.
3. Vacuum cleaner or soft, damp cloth to clean
treadmill’s entire cover area.
When not using product for an extended period of
time the product should be disconnected from the
power supply.
To avoid serious injury or death:
• Replace worn or damaged
components immediately and keep
the equipment out of use until
repair is completed.
• Unplug unit when not in use or
when performing maintenance.
Warning: Equipment hazard
Treadmill Balance
P
lace the running machine on a level floor for
avoiding off-balance. If that is not possible,
adjust the treadmill by altering the big screws with
plastic head located underneath the frames.
Check if the treadmill is balanced:
1. Stand on the machine with your feet on the side
frames.
2. Put your weight on the right side first and then switch
to the left side.
3. If you feel any shakiness, adjust those big screws
with plastic head.
5 steps to lubricate
the JLL D100 treadmill
1. Unplug the treadmill.
2. Access to the deck by
lifting the belt on the treadmill
up with your fingers or with
something flat and no sharp.
3. Look at the running board or
touch it to check if it is oily or
not. In case of dryness, use
the lubrication oil provided
with every treadmill machine,
apply it on the running deck
and spread a straight line
down the side of the deck.
4. Repeat on the other side.
5. Turn on the machine and
leave it running for around
2-3 minutes at 3-4 km/h.
Walk on the treadmill to help
spreading the lubrication oil.

Treadmill Lubrication
If the level of friction between the deck and
the belt is high, it will damage the motor
and electronics. The running belt must be
lubricated by a special lubrication oil after a
period of usage. A well-lubricated treadmill
will have a smooth running and last longer.
Recommendation:
• Less than 3 hours per week of use,
lubricate it every 6 months.
• 3-6 hours per week,
lubricate it every 3 months.
• More than 6 hours per week,
lubricate it every month.
Tool Required:
• Special lubrication oil
(provided in the box)

Adjust Running Belt
After a period of time, the user will feel there is
a pause sensation whilst running. Running belt
can loose and stretch a bit over time causing a
slipping sensation if it is not adjusted and tightened
when is needed.
If the belt is too tight, this may cause harm to
your motor and/or roller. A belt too loose or too tight
can cause wear and tear of both the belt and the
board.
Check If The Running Belt Is Loosen
1. One way of checking is every time you use the
treadmill, set the speed at 2-3 km/h.
Walk on the machine and try to stop the running
belt with your feet while holding the handrails
and pulling your body on the opposite direction.
If the belt stops, means that it is loosen and
needs to be tightened.
2. Another way is checking if the gap between the
running belt and the running board is smaller
than 5-6 mm, that means that the running belt is
loosen.
Tight The Running Belt:
1. Power off.
2. Turn the two belt adjustment screws,
located at the rear, clockwise to tighten
the belt slightly by quarters.
3. Get back to the treadmill and check the belt
(read description above). If it is still loose,
re-adjust the belt screws by another quarter.
Until you get a tighten belt.
4. Run the machine on its own for 1-2 minutes to
see if the belt stays in the middle.
5. Do the final test. Leave the machine running for
a couple of minutes at 6-8 km/h
6. If the running belt stays in the centre, we can
use the treadmill straight away.
Adjust The Belt When Is
Not In The Centre (Bear Left Or Right):
Usually between the frames and the running belt
there should be a gap of 5-6 mm on both sides. If
that gap is different it means that the belt is
eccentric. So we have to put it back to the right
position by following these steps:
1. Power on and set the speed at 2-3 km/h and
adjust the screw at the end of the treadmill
slowly with the Allen key.
2. If the belt slants to the left, adjust the left bolt
clockwise or adjust the right bolt counter
clockwise. If the belt slants to the right, adjust in
the opposite manner.
3. While adjusting the belt, check if the gap of
difference has disappeared, if it is still there,
screw the bolt again. Repeat this procedure until
the running belt is in the centre. It does not need
to be aligned perfectly, but ensure it is not
scraping or rubbing on anything on the sides.
4. Set the speed at 6 km/h to check if the
running belt is still in the same position. Once
you checked that, the treadmill is ready to use.
The running belt should be replaced every 24.000
km. The running deck should be flipped every 24.000
km and replaced every 48.000 km. A service prompt
will appear at this interval and the parts will need to
be replaced.

Adjust Motor Belt
After a period of time, the user will feel there is a pause sensation whilst running. That may be due to a
loose drive belt, so adjust the motor belt would be necessary. First of all, you have to check if it is loose
following the steps below:
Check If The Motor Belt Is Loosen
1. Unplug the treadmill.
2. Remove the motor cover by unscrewing the bolts on each side. You will see the motor located on the left
hand side of the treadmill.
3. The easy way of checking is by touching the drive belt to feel if it is slack. If you can wiggle the belt up and
down, means that the drive belt is loose.
4. Another way of checking is setting the speed at 2-3 km/h. Walk on the machine and try to stop the running
belt with your feet while holding the handrails and pulling your body on the opposite direction. If the motor
pulley stops and the front drive roller keeps running means that the motor belt is loose and it needs to be
tightened.
Tight The Running Belt:
1. Power off.
2. Locate the four bolts holding the motor.
3. Loosen those four bolts, but do not remove them.
4. Locate the long tensioning bolt that goes from the front edge of the treadmill to the front edge of the motor
pallet. NOTE: You should remove the plastic cover to have access to the long tension bolt.
5. Use an Allen key in a clockwise sensation to tighten the tensioning bolt just enough to remove the slipping.
6. Check the tension on the belt.
7. Power on the machine and check if the motor belt is still loose.
NOTE: DO NOT tight the motor belt too much, it will cause the motor shaft to snap.
