Usually a spark means you have a problem with either the drive motor or motor controller board became damaged. Unplug unit remove the motor shroud physically inspect the motor and board for any signs of arching then replaced the board. Next use a multi meter to check continuity of the drive motor by removing the red and black leads that attached to the board if a reading is much more than 1.0 to 2.0 ohms then your motor is also damaged need to be replaced.

SOURCE: Where can I purchase a teflon spray lubricant for treadmill? or should have the lubricant you need. Order it online and they should be able to ship it directly to your house. I service tunturi treadmills, although I haven't come across a teflon lubricated machine, it is very important with these machines you stick with the manufacturer specified lubricants.

Dear Sir:

I will try to help you:

If any error code appears on the display or there are other

malfunctions, proceed as follows:

1. Turn off the power switch for a minute and then
turn it on again.

2. Insure the tether key is properly inserted.

3. Insure the power cord is properly plugged.

4. Insure the treadmill is properly lubricated (see 4.3.


5. If the error code does not disappear after the

above mentioned maintenance actions, please

contact your local TUNTURI dealer. Always give

the error code and serial number (see the sticker

at the back of the frame, below the left-hand side



Lubrication is the most important service activity for the

treadmill. This is absolutely essential, if the friction of the

running deck increases noticeably or the motor begins to

heat up. Lubrication intervals must under no circumstances

exceed 200 usage kilometres; we recommend relubrication

once a month. During the first 200 km of use, the running

deck must be lubricated at intervals of 50 km. Insufficient

lubrication will cause the belt, running deck and motor to

wear out and break.

NOTE! Before you start to use your treadmill, it must be

carefully lubricated per the lubrication instructions

below! NOTE! If the treadmill is not used for at least

three weeks, it must be carefully lubricated per the

lubrication instructions below!

The need for relubrication depends to a great extent on the

running styles and weight of the user: heavy user weight and

slow speed put particular strain on the device and therefore

demand greater lubrication. Use only the teflon enclosed to

lubricate the treadmill. Contact your local TUNTURI dealer

for further supplies of teflon.

NOTE! The device must under no circumstances be

lubricated with silicone!

Please apply teflon by using the pressurised can provided
with these instructions.

instructions on the teflon bottle carefully.

1. Let the treadmill run at a slow speed and spray

teflon into the lubrication pipe underneath the

treadmill. The pipe is marked with a decal.

2. When teflon is applied for the first time, the

spraying time with the pressurised can should be

approximately 20 seconds. Later, a spraying time of

10 seconds is sufficient.

3. Teflon drops through the holes of the lubrication

pipe to the center of the running belt; the treadmill

is instantly ready for use.

Please ensure after each time that you relubricate your

treadmill that a strip of about 8" wide on the underside of the

running belt becomes moist with teflon oil along its whole
length. If necessary,

If you need further assistance, please reach me, sincerely. God bless you.

From time to time, error codes will pop up on your treadmill. It just takes a quick second to clear the error log and get the treadmill up and running again.
1.When the treadmill is not in use, press the "Stop," "ENTER" and "QUICK START" buttons in rapid succession. The "RESET" button can also be used, in place of the "Stop" button.
2.Press the "ENTER" button three times to access the treadmill's error log.
3.Press the up or down arrows to scroll through the error codes, if necessary for club or personal logging purposes.
4.To view the treadmill's odometer reading when a particular error code was elicited, press "SELECT" while a particular error code is displayed.
5.To clear the error log, press "QUICKSTART" for a minimum of four seconds while viewing the list. Prompts will appear on the display and let you know when the log has been deleted.
I hope you find it very helpful.

Hi, We have had our treadmill for about 3 weeks. For the past few days, when we start it up, after about 15 seconds of running on it, it stops and Error 1 shows up on the screen. It is a t40 model. ...

error 1 is a fairyl universal code for treadmills that means your control board has gone bad. Here is a list of things that will cause this to occur:

1. Improper lubrication of belt/deck (too much friction and amperage draw)

2. electrical variance (example: going from US 110 to foreign 220)

3. potentiometer on control board may be set too low (usually blue box with turnable dial) - to change this you would have to turn the dial ever so slightly and test after each movement until the belt starts to run on its own without the error.

other than the above issues you would have to replace the motor control board
