Treadmill Lubrication; Adjust Running Belt - JLL S400 Manual Book

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,

Adjust Running Belt

A
fter 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.

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)
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.
