Lubrication (Fig. F-4); Troubleshooting - Tunturi T20 Manuel De L'utilisateur

- Clean the visible parts of the equipment with a vacuum cleaner
with a small suction nozzle
- Regularly check that all screws and nuts are tight.
Belt and Running Deck
Your treadmill uses a very high-efficient low-friction bed. Performance
is maximized when the running deck is kept as clean as possible.
Use a soft, damp cloth or paper towel to wipe the edge of the belt
and the area between the belt edge and frame. Also reach as far
as practical directly under the belt edge. This should be done once
a month to extend belt and running deck life. Use water only - no
cleaners or abrasives. A mild soap and water solution along with a
nylon scrub brush will clean the top of the textured belt. Allow the
belt to dry before using.

Lubrication (fig. F-4)

The running belt must be checked for lubrication condition regularly.
Therefore the treadmill comes with a 300 hours reminder function.
The "TIME WINDOW" will display "OIL" and will make an acoustic
beeping sound every 10 seconds to remind you. Follow the below
checking procedure and eliminate the "OIL" message and acoustic
warning signal by pressing and hold the "STOP" button for at least 3
seconds during this warning signal.
⚠ WARNING
• Before lubrication, remove the mains plug from the wall socket.
⚠ CAUTION
• We recommend to check the running belt lubrication at least
once every month, as more factors than time can be effective to
the lubricant conditions.
• 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.

Troubleshooting

Despite continuous quality control, defects and malfunctions caused
by individual components may occur in the equipment. In most cases
it's unnecessary to take the whole device in for repair, as it's usually
sufficient to replace the defective part.
If the equipment does not function properly during use, contact your
Tunturi dealer immediately. Always give the model and serial number
of your equipment. Please state also the nature of the problem,
conditions of use and purchase date.
If you require spare parts, always give the model, serial number of
your equipment and the spare part number for the part you need.
The spare part list is at the back of this manual. Use only spare parts
mentioned in the spare part list.
