1.5 Lubrication Guide

Basically, initial lubrication is performed at factory, but the oil could be dried during transportation or stock in your warehouse.

As soon as you complete installing, please lubricate and then make sure that oil is enough or not as below.

1) Turn off treadmill .

2) Push the striding belt backward using your feet while holding the front handle bar or side handle bar.

3) You can judge whether the friction is enough or not by feeling the smooth move of the belt. Lubrication is needed if the belt is not pushed well.

z Lubricant prevents the belt and deck from being damaged by frictional heat, which extends life span of the deck and belt. z Use the lubricant provided by Motus only. KF54 silicone fluid made from Shin-Etsu Chemical Co. Ltd.

How to manage automatic lubrication system (M990T, M990TL)

A certain amount of oil is lubricated automatically every lubrication interval which is preset at Manager Mode. Default lubrication amount and lubrication interval are set up to, for instance, 30cc and 500km, respectively, which can be set at Manager Mode. Therefore, it is recommended that fitness club manger set up the lubrication amount and interval according to club condition.

A volume of lubricant tank is about 270cc, and if residual amount of oil is less than 20%, the warning SYMBOL is displayed on the screen with a beep. At that time, fill the tank as instructions below.

1) Turn OFF the treadmill and open motor hood.

2) Open the cap of oil tank by turning it with hand.

3) Fill the empty tank fully with the oil provided by Motus. Keep in mind that automatic lubrication system doesn’t work properly if oil is not filled full.

4) Close the cap of oil tank and put the motor hood in place.

5) Turn ON the treadmill. Message indicating oil lack will be still displayed on the screen with the beep.

6) To input “finishing oil-filling”, press buttons in the order as below.

15

‘INCLINE ▽’ -> ‘INCLINE △’ -> ‘SPEED ▽’ -> ‘SPEED △’ -> ‘ENTER’

Keep in mind that this step must be done after filling the tank fully.

7) The warning SYMBOL and beep disappears.

How to inject lubricant manually (M995T, M995TL)

To judge proper lubrication timing, you can feel the friction intensity by pushing the striding belt backward using your feet while holding the front handle after turn OFF the treadmill.

1. Fill the lubricator with the oil Motus provided.

2. The conduction hole for the lubrication is at the right corner on the front of the treadmill as shown in the picture.

3. Insert the pipe tip of the lubricant to the end through the conduction hole to spread out the lubricant on the center of the belt.

4. Inject the lubricant into the conduction hole by squeezing the lubricator about 20 times under the belt speed of 4km.

The amount of 30 cc is recommended.

5. To spread out the lubricant all round on the belt, operate the treadmill for a few minutes.

6. Lubricate more than twice a month.

How to eliminate warning beep & symbol requiring lubrication (M995T, M995TL)

Although lubricant is not injected automatically, lubrication interval can be set up at Manager Mode, for instance, 500km. If the interval is too short or long, you can adjust the interval at Manager Mode. Warning beep & symbol every lubrication interval makes you easy to lubricate without any need to consider lubrication timing.

To reset the warning beep and symbol after completing manual lubrication, press buttons in the order as below.

‘INCLINE ▽’ -> ‘INCLINE △’ -> ‘SPEED ▽’ -> ‘SPEED △’ -> ‘ENTER’

The warning beep and SYMBOL disappear.

16

Numeric value 5 in management mode means interval of 500 km. If you exercise on treadmill at 8km/h for 10 hours a day, total distance a day is

80km and the warning beep and symbol appears every 6.25 days corresponding to 500 divided by 80.

The speed (8km/h) and workout duration for a day (10 hours) depend on the numbers of the users or utilization rate ay Gym.

2.1 How to Stabilize the Treadmill

Two front casters and two adjustable rear feet (or stabilizing leg) support the weight of both the treadmill and a user exercising on it. The rocking motion or striding belt misalignment may be caused when one of them is not resting on the floor.

1) Check if the treadmill is even on a solid and flat surface. A BUBBLE LEVEL can be used to ensure proper leveling. Determine which foot is not resting on the floor.

2) Loosen the nut on the top of adjustable foot by turning it clockwise.

3) Once the nut is loosened, turn adjustable foot with hand until the rocking motion ceases.

4) After leveling, turn the nut counterclockwise and tighten it.

Note: Adjusting height must be done while rear side of treadmill is lifted up. Do not adjust more than 1/4 of entire adjustable rear foot’s height.

19

2.2 How to Align Striding Belt

The belt is properly aligned at the factory before shipment. However, while delivering or exercising, the belt can be misaligned from the original center position. The correct alignment or striding belt is critical to the smooth operation of the treadmill.

2.2.1 When the belt is off center to either right direction or left direction

1) Level and stabilize the treadmill prior to any alignments or tracking adjustments.

* The belt may move off center by using the treadmill on uneven surface.

2) Turn on the treadmill and then check if the belt drifts off center or not while treadmill is operated with the speed of 5km/h for a few minutes.

3) Turn off the treadmill after keeping in mind whether the belt is off center to which direction, left or right.

4) Make sure the striding belt has completely stopped.

5) Find the right belt tensioning bolt in the rear end cap of the treadmill.

Make tracking adjustments using the 10 mm hex key wrench provided as shown. z If the belt is off center to the right, turn the right adjusting bolt 1/4 turn clockwise, which brings the striding belt back to the left. z If the belt is off center to the left, turn the right adjusting bolt 1/4 turn counterclockwise, which brings the striding belt back to the right.

Note: Do not turn the adjusting bolt more than 1/4 at a time. Over-tightening the bolt can damage the treadmill. Do not exceed one full turn of the adjusting bolts in either direction.

6) Turn ON the treadmill, press START/STOP, and then operate the treadmill with the speed of

5km/h.

7) Observe the striding belt for a few minutes. The belt should be centered on the deck.

8) If you need additional alignment, repeat step 2) through 7) of this procedure until the belt is properly aligned.

CAUTION: If you hear any chafing, the belt is not center-aligned or the belt appears to be

20

getting damaged, stop the treadmill and contact authorized local dealer.

2.2.2 When the belt is diagonally tilted

When the Striding Belt is diagonally tilted as shown, the Front Roller (F4) needs to be aligned by following steps.

1) Turn off the unit power at the switch and then unplug the line cord at wall outlet.

2) Remove three Motor Cover screws (B20) and then lift the cover

(T1) out from between the upright Supports.

3) Turn the Hex Bolt (B2) in either direction to compensate for the tilted

Striding Belt.

When the Striding Belt is tilted as shown in A), turn the Hex Bolt (B2) by 1/4 turn in the direction of (1).

When the Striding Belt is tilted as shown in B), turn the Hex Bolt (B2) by 1/4 turn in the direction of (2).

Note: Make adjustments in 1/4 turn.

The position of the Front Roller to be changed by the direction of the Hex Bolt (B2) is indicated in the figure.

4) Re-assemble the Motor Cover in the reverse order of removal and make sure that the Striding Belt is properly aligned after turning on the unit power and operating it with the speed of 5km/h for a few minutes..

5) Repeat this adjustment until the

Striding Belt is properly aligned.

21

2.3 How to Adjust Striding Belt Tension

Belt tension is properly adjusted before delivery. However, while exercising for a long time, the tension can be loose. Belt tension is adjusted by moving the position of rear roller using the belt tensioning bolt of END CAP.

Note: it is very important to keep belt’s tension constant to avoid belt slips during footfall for user’s safety.

1) Turn on the treadmill, press START/STOP, and then operate the treadmill with the speed of

4km/h. Walk on the treadmill. Tightly grip the front handlebar and apply force with feet on the striding near the motor cover against the moving direction. If the belt slips, do steps from 2). If it does not slip, the tension is proper.

2) Stop the treadmill for a safety during adjustment and prepare 10mm wrench

Do not adjust tension while treadmill is in operation.

Warning: If you adjust the belt tension when the treadmill is in operation, it is very dangerous because sleeve or a part of body may be caught in roller or belt.

3) Locate the two belt tensioning bolts in the end caps on each rear side of the treadmill as shown, which enables to adjust belt tension. When turning this bolt, a position of roller moves back and forth. To move backward the roller, turn the bolts clockwise. To move forward the roller, turn the bolts counterclockwise.

4) Put 10mm wrench into the hole of the Right End

Cap as shown and then turn the wrench 1/4 turn clockwise.

5) Put 10mm wrench into the hole of the Left End Cap as shown and then turn the wrench 1/4 turn clockwise. Equal amount of rotations should be performed on right tensioning bolt and left tensioning bolt. If not so, the belt is off center to either right direction or left direction.

6) Repeat steps 1) through 5) until the belt no longer slips.

Do not exceed one full turn of the adjusting bolts in either direction. Over-tightening of the bolts may over stretch and damage the striding belt or roller bearings.

If the belt continues to slip in spite of the belt tension adjustment, verify that Drive Motor Belt can be the cause of the slip.

22

2.4 How to Adjust Motor Drive Belt Tension

The tension of Motor Drive Belt (M3, Poly-V Belt) can be loosened by a long time use and it can cause a slip between The Drive Motor Pulley and Motor Drive Belt. The tension is corrected by adjusting the mounting position of the Drive Motor (M1).

Do the steps below while referring to the following Exploded Views in Appendix.

A.1 M990T

B.1 MAIN BODY_FRONT A

C.1 MAIN BODY_REAR

1) Stop the treadmill after lifting up the unit at maximum by operating Incline Motor.

2) Turn off the unit power at the switch at the state of the treadmill lifted-up and then unplug the line cord at wall outlet.

3) Remove three bolts (B20) and then lift Motor Cover (T1) out from between the upright

Supports.

4) Loosen four nuts (N2) securing the Drive

Motor (M1) by one or two turns to allow the

Drive Motor to be moved by the Tension

Bolt (B7).

5) Turn the nut (N3) in the direction of arrow

Note: One turn of the Tension Bolt makes the Drive Motor move by 1.5 mm. Keep in mind that tightening the Tension Bolt too much can damage the internal bearings of the Drive Motor or Front Roller .

7) When the tension reaches 160 Hz, secure two nuts (N2) diagonally.

Note: It is desirable to set the tension to

150Hz before tightening two nuts (N2)

23

because tightening two nuts (N2) increases the tension of the Motor Drive Belt.

8) Measure the Tension again. If the tension is lower than 155Hz or higher than 165Hz, readjust the tension 4 through 8) until it reaches 155Hz to 165Hz.

9) When the tension reaches 160 Hz, tighten the nut (N3) securing the Tension Bolt (B7).

10) Tighten remaining two nuts (N2) diagonally.

11) Make sure that the nut (N3) securing the Tension Bolt (B7) is tightened.

12) Re-assemble remaining parts in the reverse order of removal.
