Lubrication (Fig. F-4); General Cleaning; Belt Adjustments - Tunturi T20 User Manual

Lubrication (fig. F-4)

The running belt must be checked for lubrication once
per 2 months, based on the average use of 60 minutes
per day.
WARNING
• Before lubrication, remove the mains plug from
the wall socket.
CAUTION
• Only lubricate the running belt if necessary. If
you apply too much lubricant, the running belt
will slip easily due to lack of friction.
- Stand steadily on the running belt.
- Take hold of the front handlebar and push the
running belt with your feet so that it slides back and
forth. The running belt must move smoothly and
evenly without making sound.
- If the running belt does not move smoothly and
evenly or if the running belt does not move at all,
touch the underside of the running belt with your
fingertips to check the lubrication:
• If you feel lubrication or your fingertips are shiny,
there is sufficient lubrication on the running belt.
• If you do not feel lubrication or your fingertips
are dusty or rough, apply lubricant (15-20 ml)
in the middle of the running deck under the
running belt and let the equipment operate at
5km/h for at least 5 minutes.
• After lubrication, do not fold the equipment
before having done a workout for 20 minutes
with a speed of at least 5 km/h. The lubricant will
be spread evenly over the running belt.
Belt Dust
This occurs during normal break-in or until the belt
stabilizes. Wiping excess off with a damp cloth will
minimize build-up.

General Cleaning

Dirt, dust, and pet hair can block air inlets and
accumulate on the running belt. On a monthly basis:
vacuum underneath your treadmill to prevent buildup.
Twice a year, you should remove the black motor hood
and vacuum out dirt that may accumulate.
UNPLUG POWER CORD BEFORE THIS TASK.

Belt adjustments

Adjustment must be made from the rear roller. The
adjustment bolts are located at the end of the step rails
in the end caps.
- Tighten the rear roller bolts (clockwise) only enough
to prevent slippage at the front roller. Turn both
running belt tension adjustment bolts in increments
of 1/4 turn each and inspect for proper tension by
walking on the belt at a low speed, making sure the
belt does not slip. Keep tensioning the bolts until
the belt stops slipping.
- If you feel the belt is tight enough, but it still slips,
the problem may be a loose Motor drive belt under
the front cover.
- Do Not Over-tighten
Over tightening will cause belt damage and
premature bearing failure.
Running belt tracking adjustment
The performance of your treadmill is dependent on
the frame running on a reasonably level surface. If
the frame is not level, the front and back roller cannot
run parallel, and constant belt adjustment may be
necessary.
The treadmill is designed to keep the running belt
reasonably centered while in use. It is normal for some
belts to drift near one side while the belt is running with
no one on it. After a few minutes of use, the running
belt should have a tendency to center itself. If, during
use, the belt continues to move toward one side,
adjustments are necessary.
Exception: During rehabilitation where the user is using
one leg much stronger than the other, it might happen
that the running belt drifts to one side. In these cases
you should not adjust unless the running belt does not
centre itself during normal condition usage.
To set running belt tracking (fig. F-5)
A 10 mm Allen wrench is provided to adjust the rear
roller. Make tracking adjustments from the left side only.
Set belt speed at approximately 3 to 5 kph.
Remember, a small adjustment can make a dramatic
difference!
Turn the bolt clockwise to move the belt to the right.
Counterclockwise to move to the left. Turn the bolt only
a 1/4 turn and wait a few minutes for the belt to adjust
itself. Continue to make 1/4 rotation turns until the belt
stabilizes in the center of the running deck.
The belt may require periodic tracking adjustment
depending on use and walking/running characteristics.
Some users will affect tracking differently. Expect to
make adjustments as required to center the tread-belt.
Adjustments will become less of a maintenance concern
as the belt is used. Proper belt tracking is an owner
responsibility common with all treadmills.
NOTE
• Damage to the running belt because of incorrect
running-belt adjustments is not covered by the
products warranty.
