Treadmill service: Replace front roller

To replace the front roller, follow the procedure below:

• turn off the treadmill and disconnect it from the power supply;

• open the motor protection cover;

• loosen the rear roller trying to keep the roller perpendicular to the running deck;

• completely unscrew the right-hand adjusting screw of the front roller;

• remove the drive belt from the roller and motor pulleys;

• remove the front roller and replace with the new roller;

• reposition the drive belt on the roller and motor pulleys;

• screw the right screw on the front roller and align it correctly so that it is exactly perpendicular to the deck of the treadmill (see following photo):

 

• check the exact alignment of the transmission belt (see the following photo);
  
   
  • re-tighten and adjust the rear roller;
  • turn on the treadmill and set the manual program to 5 - 6 km/h to perform the re-alignment of the rollers and centering of the belt;
  • switch off the treadmill and reposition the motor protection cover.

Weslo Assistance: Electrostatic discharge

Contact us for assistance and spare parts

We see in this article a suggestion of our technicians for assistance on the Weslo treadmills.

If the user receives a small electric discharge during operation of the treadmill, you can try solving the problem in the following manner

• check the nature of the "discharge”, i.e. if it derives from static or other phenomena;

• if the electric discharges are of an electrostatic nature, check the environment in which the customer is running and with what types of clothes he performs the exercises. If necessary replace the belt, because old running belts may cause electrostatic discharges;

• if the electric discharges are not of an electrostatic nature, check the grounding system of the treadmill and all its components. Check the integrity of the wiring and that there are no components of the controller under tension in direct contact with parts of the frame;

• check that the customer's grounding system is up to standard;

• check the pulse sensors, as in some cases the wires leaving the sensor touch or are pinched to the frame (see figure). In this case isolate the part where the contact occurs (see figure) and reposition the hand-pulse (see figure)

• if, after careful checking of the connections and any replacement of the belt or other parts, no appreciable results are obtained, the cause may lie on the frame painting.

Treadmill motor: replace it and adjust the trimmer of the board

Some things to consider when replacing the treadmill motor.

Over time, the ways in which the power ratings of treadmill motors have been calculated have changed. In the past, the c.d. "continuous duty power" S1 was calculated on the basis of the motor insulation class and the type of use (8 duty cycle classes, S1 to S8, defined by the IEC). Subsequently for marketing reasons, powers related to discontinuous operation were used. So, the same engine labeled in the past 3/4 HP (0.75 HP) can now be labeled 2.75 HP, because instead of doing the calculation in S1 class it is done in class 6.

 

Test of the armature of a motor, weight verification

 

In general, the real power of the motor depends primarily on the diameter and secondly on the length of the motor (the diameter, however, affects much more). It can be considered that motors with diameter from 8 / 8.5 cm are from about 1.5 HP continuous (some more serious manufacturers mark them 1 HP), a diameter of 9.5/10.0 sounds reasonable for 1.75 HP, 10.5 cm for 2.25, 12 cm for a 2.5 / 2.75. Besides it is difficult to go on motors for domestic use. Small motors break down more frequently (they dissipate heat much worse, have a smaller manifold, etc.). Some construction details could make one motor a bit better than another of equivalent dimensions (e.g. the one in the picture above has the slats of the oblique armature)

 

Turning the TORQUE trimmer clockwise adjusts the torque given to the motor

When replacing a smaller size motor with a larger one, it is often necessary to adjust the trimmer on the board.

It may be necessary to adjust the IR and LIMIT trimmers (also called TORQUE)

The SPEED trimmer is used to adjust the ratio between the input signal to the motor board (coming from the console) and the relative output on the motor (e.g. from a 5V regulation from the console = 140V to the motor can switch to 5V to the board = 180V to the engine). This adjustment is usually useless because a retraction system (optical or magnetic speed sensor) returns the real speed to the console and the console consequently adapts the signal sent to the engine control card as long as the read speed does not match the one set on the console.

Treadmill belt | when to replace it and how to adjust it

ATTENTION: the belt must be replaced if:

- it is not possible to tension (it continues to slip even after having it tightened)

- the black rubber is damaged or dry

- it tends to open up where there is a joint

- has swollen and touches the frame

- the white cloth underneath the belt is damaged or missing

In all these cases you can buy a low friction running belt for your treadmill on our e-shop

http://www.partsfortreadmill.com/parts-for-treadmill/belt-for-treadmill/

If you need spare parts or assistance, contact us.

  

Preliminary operations

1. Before starting, make sure the treadmill is turned off and unplugged from the power outlet.

2. To remove dust, pass the vacuum cleaner suction nozzle around the visible components.

3. For the removal of films or dirt, use a damp cloth with a mild detergent applied on the cloth only.

4. Do not immerse the components of the treadmill in any type of liquid.

Belt alignment

Make sure the walking belt is always centered to the treadmill frame. The way you run on the treadmill and a non-flat floor surface are two possible causes of belt misalignment.

When the belt is misaligned, it is necessary to act on the two adjustment bolts on the treadmill back.

1. Press "START" to start the running belt and then increase the belt speed up to 5 Km/h.

2. Stand behind the treadmill to determine in which direction the belt tends to move.

3. If the belt moves to the left, turn the left adjustment bolt a quarter of a turn clockwise and the right bolt a quarter turn counterclockwise (See FIG. C)

4. If the belt moves to the right, turn the left adjustment bolt a quarter turn in the counterclockwise direction and the right bolt a quarter turn clockwise (See FIGURE D)

5. Observe the path of the belt for about one minute. If necessary, repeat the operations in steps 3, 4 and 5.

 

Adjustment of the tension of the treadmill belt

Adjust the tension of the treadmill belt if it starts to slip on the rollers.

Keep the belt as slow as possible while adjusting the treadmill belt tension.

1. Press "START" to start the treadmill, then set the speed to 1 Km/h.

2. Slow down the belt holding yourself firmly to the handlebar and applying more weight on the belt as if walking downhill. By breaking considerably, the belt may slip.

3. If the belt slips, stop the treadmill, turn both the screws a quarter of a turn clockwise and repeat steps 2-3 if necessary.

Note: take care not to over-tension the belt. Stop as soon as the belt no longer slips. If it keeps slipping, replace the belt.

Icon MC2100E repair | treadmill controller checks using LED

If you need spare parts or assistance, contact us.

To find out if the controller has not been damaged etc., follow the steps described below

- with the board installed and main switch off, keep an eye on the red LED on the board (there is only one). When you turn on the main switch, the LED MUST NOT light up simultaneously with the activation of the switch, but it must light up steady after a certain delay (some instants).

At the beginning, it makes an almost imperceptible "lighting-up", then it turns on fixed. If it becomes fixed immediately, the control board is damaged (programming error) and you have to change the controller.

Other cases in which the board is damaged, always linked to the LED are:

- LED on steady immediately with weak light.

- LED completely off, but dashboard / console turned on (probable microprocessor in short).

If the board is not damaged or does not have the micro damage, then it is potentially repairable.

Note: starting from May 2015, Treadmill Spare Parts, together with the Repairs Laboratory, has developed a replacement chip which allows the successful repair of all defective Icon boards of the MC2100, MC66 and MC2000 types even in the event of a faulty original chip.

E1 E2 treadmill errors/ speed sensor

The errors E1 and E2 on the treadmill often depend on problems with the speed sensor. In fact, they indicate the wrong reading of the actual speed of the treadmill.

If you need spare parts or assistance, contact us.

The most common sensor is the magnetic type (in photo). In most cases, the sensor has a "cigar" shape while in some cases a square shape. The square sensor is identical to the cigar sensor in the functionality. In both cases, before proceeding with the replacement it is advisable to check that the magnet placed on the pulley is close to the sensor (2-3 mm) otherwise the missing reading may depend on the fact that the sensor has moved due to the treadmill vibrations.

On our e-shop you can buy sensors for treadmills.

Belt for treadmill position control guides

Applicable for different types of treadmills manufactured by Strengthmaster and other makers. Useful in case the belt guides are positioned incorrectly and ruin the running belt at the sides.

1. Under the running platform, welded on the frame there are two guides.

 

2. Temporarily offset the belt under the guide.

3. Measure the distance between the driving footrest: this should be between 17 and 18 mm.

 

4. If the distance is different from the specified distance, use a key (10 mm) or another tool to restore the correct distance.

5. Be very careful to act exactly on the point shown in the figure to avoid damaging the guide.

6. Repeat the same operation on the other guide.

7. Center and tension the belt.

Motor with electric discharges or incorrect calibration of the treadmill controller

n this video we show a malfunctioning treadmill. In the video you can see how the motor starts and sometimes a red light on the board lights up (current limit reached).

The defect may be due to an incorrect calibration of the LIM trimmer on the board (too low) or more likely by a demagnetization of the motor, which must therefore be replaced.

Find spare parts and assistance for treadmills on the website: http://www.partsfortreadmill.com

 

In this second video, we show abnormal behavior at a more sustained rate.

First of all, it can be seen that the motor tends to go much too fast, i.e. at a speed exceeding the one set on the console.

Moreover, it is seen that as soon as a load is applied (the person steps on), the motor slows down significantly and the red light on the board turns on.

This is another symptom of a demagnetizing engine. The motor must be therefore replaced.

 

In this last video, we see that changing the setting of the IR trimmer causes sudden changes to the motor rotation speed. The IR trimmer is the regulation of the minimum power of the motor (to be set according to motor specification).

The technician also tries to set the LIMIT trimmer. LIMIT sets the max. current to the motor. Clearly there is no change as this trimmer comes into play as protection of the board when the motor requires a lot of current.

The third SPEED trimmer is in this configuration irrelevant because the speed is controlled on this treadmill (and on many others) directly from the console, so the control board cannot make adjustments.

E3 E4 error on Technogym Run XT 600

In this video we show the E3 / E4 error on the Technogym Run XT 600 gym treadmill.

 

Based on the error codes (see http://www.treadmillsrepair.co.uk) it is possible to identify the cause of the fault. In this specific case on the inverter E4 was displayed. The inverter had to be replaced, because it was short-circuited. We replaced it with one of the new ones supplied by Treadmill Parts http://www.partsfortreadmill.com/inverter-compatibile-xt-technogym.html
