your head to your chest for one count.
Shoulder Lifts
Lift your right shoulder up toward
your ear for one count. Then lift
your left shoulder up for one
count as you lower your right
shoulder.
Side Stretches
Open your arms to the side and
continue lifting them until they are
over your head. Reach your right
arm as far upward toward the
ceiling as you can for one count.
Feel the stretch up your right side.
Repeat this action with your left
arm.
Quadriceps Stretch

BELT ADJUSTMENT:
IMPORTANT: DO NOT OVER TIGHTEN THE TREADMILL BELT! THIS WILL VOID YOUR BELT WARRANTY!
You may need to adjust the running belt during the rst few weeks of use. Over time, you will need to adjust it less frequently as the running
belt will adjust to your walking or running style. The treadmill belt may stretch or become off-center within the rst few weeks or months and
this is perfectly normal during the break-in period.
ADJUSTING THE TREADMILL BELT TENSION:
If the running belt feels as though it is “slipping” or hesitating when you plant your foot during a run, the tension on the treadmill belt may have
to be increased. Again, this is normal and easy to rectify.
A. Place a hex wrench on the LEFT side tension bolt. Turn the wrench clockwise 1/4 turn to draw the rear roller and increase the belt tension.
B. Repeat STEP A on the RIGHT belt tension bolt. You must be sure to turn both bolts the same number of turns, so the rear roller will stay
square relative to the frame.
C. After completing STEP A and STEP B, walk on the treadmill to determine if the “slip” is gone.
D. Repeat STEP A and STEP B until the slipping is eliminated.
E. Be careful not to over tighten the treadmill belt as you can create excessive pressure on the front and rear roller bearings and or tear the
running belt seam. An excessively tightened running belt will damage the roller bearings and treadmill belt.
F. If your belt is no longer “slipping” but off center, STOP and read below for how to center the treadmill belt.
TO DECREASE THE TENSION ON THE TREADMILL BELT, TURN BOTH BOLTS COUNTER- CLOCKWISE THE SAME NUMBER OF
TURNS.
IMPORTANT: If your treadmill belt is rubbing on the side frame or is very close to touching the side frame you will need to center the
treadmill belt with the treadmill off. Once you adjust the rear tension bolts properly, then turn the treadmill on to 2.0mph (no faster) and
with your foot, manually “push” the treadmill belt away from the side rail. This will safely remove the belt from the side rail and speed
up the “centering” process. Use extreme caution while the treadmill belt is moving.
CENTERING THE TREADMILL BELT
When you walk or run, you may push off harder with one foot than the other. The severity of the deection depends on the amount of force
that one foot exerts in the relation to the other. This deection can cause the treadmill belt to move off center. This deection is normal and the
treadmill belt should center on its own when the treadmill is unoccupied. If the treadmill belt remains consistently off-center, you will need to
center the treadmill belt manually (see below).
A. Observe the treadmill belt and see if it is
touching either the right or left side of the frame. If
it is, read the IMPORTANT instructions above!
B. Start the treadmill without anyone on the
treadmill belt. Press the Speed Up button until the
speed reaches 2.5 mph, or a safe walking speed
for you. Use extreme caution while the treadmill
belt is moving.
C. Observe whether the treadmill belt is closer to
the right or left side of the deck.
If you need to align the treadmill belt from the
left side to right side, always adjust the left side bolt
only. The simple rule of thumb for aligning the belt is
this: working from the (user) left side bolt, if you need
to move the belt to the right, “tighten” the left side bolt
(turn clockwise in 1/4 turns only). This will move the belt
slightly to the right.
If you need to align the belt to the left, “loosen” the
left side bolt (turn the bolt counter clockwise in 1/4
turns only). This will move the treadmill belt to the left.
Anytime you need to either tighten the belt or align the belt, you should have the treadmill running at around 2.5 mph. Also, these adjustments
can take up to 30 seconds to alter the position of the belt so be patient.
NEVER OVER TIGHTEN THE TREADMILL BELT AS IT WILL RUIN YOUR TREADMILL!
Use extreme caution while the treadmill belt is moving.
You may need to adjust the running belt during the first few weeks of use. All running belts are properly set at
the factory. It may stretch or be off-center after use. Stretching is normal during the break-in period.
ADJUSTING THE BELT TENSION
If the running belt feels as though it is "slipping" or hesitating when you plant your foot during a run, the
tension on the running belt may have to be increased.
TO INCREASE THE RUNNING BELT TENSION:
A. Place 8MM wrench on the left belt tension bolt. Turn the wrench clockwise 1/4 turn to draw the rear roller
and increase the belt tension.
B. Repeat STEP A for the right belt tension bolt. You must be sure to turn both bolts the same number of
turns, so the rear roller will stay square relative to the frame.
C. Repeat STEP A and STEP B until the slipping is eliminated.
D. Be careful not to tighten the running belt tension too much as you can create excessive pressure on the
front and rear roller bearings. An excessively tightened running belt may damage the roller bearings that
would result in bearing noise from the front and rear rollers.
TO DECREASE THE TENSION ON THE RUNNING BELT, TURN BOTH BOLTS COUNTER-
CLOCKWISE THE SAME NUMBER OF TURNS.
CENTERING THE RUNNING BELT
When you run, you may push off harder with one foot than with another. The severity of the deflection depends on
the amount of force that one foot exerts in the relation to the other. This deflection can cause the belt to move off-
center. This deflection is normal and the running belt will centre when no body is on the running belt. If the running
belt remains consistently off-center, you will need to centre the running belt manually.
A). Start the treadmill without anyone on the running belt, press (SPEED UP ) bottom until speed reached 6kph.
B). Observe whether the running belt is toward the right or left side of the deck.
a. If toward the left side of the deck
Using wrench, turn the left adjustment bolt clockwise 1/4, turn the right adjustment bolt counterclockwise
1/4.
b. If toward the right side of the deck
Using wrench, turn the right adjustment bolt clockwise 1/4, turn the left adjustment bolt counterclockwise
1/4.
c. If the belt is still not centered, repeats the above steps until the running belt is on center.
C). After the belt is centered, increase the speed to 16kph and verify that it is running smoothly. Repeat the
above steps if it is necessary.

TO DECREASE THE TENSION ON THE RUNNING BELT, TURN BOTH BOLTS COUNTER-
CLOCKWISE THE SAME NUMBER OF TURNS.
CENTERING THE RUNNING BELT
When you run, you may push off harder with one foot than with another. The severity of the deflection depends on
the amount of force that one foot exerts in the relation to the other. This deflection can cause the belt to move off-
center. This deflection is normal and the running belt will centre when no body is on the running belt. If the running
belt remains consistently off-center, you will need to centre the running belt manually.
A). Start the treadmill without anyone on the running belt, press (SPEED UP ) bottom until speed reached 6kph.
B). Observe whether the running belt is toward the right or left side of the deck.
a. If toward the left side of the deck
Using wrench, turn the left adjustment bolt clockwise 1/4, turn the right adjustment bolt counterclockwise
1/4.
b. If toward the right side of the deck
Using wrench, turn the right adjustment bolt clockwise 1/4, turn the left adjustment bolt counterclockwise
1/4.
c. If the belt is still not centered, repeats the above steps until the running belt is on center.
C). After the belt is centered, increase the speed to 16kph and verify that it is running smoothly. Repeat the
above steps if it is necessary.

You may need to adjust the running belt during the first few weeks of use. All running belts are properly set at
the factory. It may stretch or be off-center after use. Stretching is normal during the break-in period.
ADJUSTING THE BELT TENSION
If the running belt feels as though it is "slipping" or hesitating when you plant your foot during a run, the
tension on the running belt may have to be increased.
TO INCREASE THE RUNNING BELT TENSION:
A. Place 8MM wrench on the left belt tension bolt. Turn the wrench clockwise 1/4 turn to draw the rear roller
and increase the belt tension.
B. Repeat STEP A for the right belt tension bolt. You must be sure to turn both bolts the same number of
turns, so the rear roller will stay square relative to the frame.
C. Repeat STEP A and STEP B until the slipping is eliminated.
D. Be careful not to tighten the running belt tension too much as you can create excessive pressure on the
front and rear roller bearings. An excessively tightened running belt may damage the roller bearings that
would result in bearing noise from the front and rear rollers.

ONE TIME BELT ADJUSTMENT
Treadmill Belt Slipping?
IMPORTANT: DO NOT OVER TIGHTEN THE TREADMILL BELT! THIS WILL VOID YOUR BELT WARRANTY!
To perform this adjustment, turn off the treadmill and unplug the power cord.
The circled image above is the drive motor adjustment bolt. If you have tried to adjust the rear rollers and the belt is still slipping then
this bolt will need to be tightened. This is a one-time adjustment and will never need to be adjusted again. Here are the instructions on
how to tighten this bolt:
IMPORTANT: Failure to follow these instructions will result in injury.
Elevate your treadmill to the highest possible elevation. Turn off the treadmill and unplug the power cord. Remove the (4)
Phillip screws located in the motor cover. You will now be able to see and adjust the drive motor adjustment bolt.
This is very important: If you have already tried to adjust the rear roller bolts (which most likely you have) then it is very important to loosen the
rear roller bolts by the same amount of turns you previously tightened them. If you are not sure, call us at 888-888-7985 (Ext 1) and we will
walk you through this step. Or, you should be able to see about a ½” gap in-between the rear roller and the plastic end cap covering the roller.
Again, at any point you can call us directly at 888-888-7985 (Ext 1).
The next step is to tighten the drive motor adjustment bolt. If it feels really loose then you can tighten it to the point where you can no longer
wiggle it with your hand. From here, you will tighten the bolt ¼ turn clockwise and then walk on the treadmill to see if the slippage is gone. If
it is not then tighten the bolt another ¼ turn clockwise. Keep repeating this to the point that the belt is no longer slipping. You do not want
to over tighten the belt. Once the belt is no longer slipping you can put the motor cover back on and lower the treadmill incline back down
to 0%. Walk on the treadmill again. There is a slight chance that the belt will slip and that is ok. Now you can proceed with the normal belt
adjustment rules listed on the previous page. Again, you will never have to adjust the motor drive adjustment bolt again.

LUBRICATION MAINTENANCE:
It is important to take good care of your treadmill deck (the walking surface underneath the belt). Using a 100% pure
silicone lubrication will also improve the performance of your treadmill by reducing the heat and friction that occur
during workouts.
NOTE: Use the silicone that is supplied with the treadmill. Additional silicone lubricant can be purchased from your
retail store.
WARNING: STOP the treadmill and remove the safety key before lubricating the running deck.
HOW TO APPLY SILICONE ONTO THE TREADMILL DECK:
1. Locate the silicone bottle. It is located in the hardware kit package included with this treadmill.
2. Cut the very tip of the applicator shaft with a pair of scissors.
3. Apply the silicone evenly on the treadmill deck as the drawing shows. The application area is only in the area
where your feet make contact with the deck. This typically is the middle 2/3rds of the deck area. Do not put too
much silicone on the deck. To apply the silicone, lift the belt up with your ngers and reach the silicone bottle as
far underneath the belt as you can and squeeze a small amount onto the deck. Repeat the same procedure from
the opposite side of the belt to reach the other portion of the deck. Slowly work your way down the treadmill deck.
You only need to apply a little lubrication in each spot. After completing the lubrication, it is recommended to now
do a workout as the heat and friction from the belt will help spread the lubrication around to the rest of the deck
area and absorb into the underside of the belt.
CAUTION: Excessive lubricant may cause the silicone to leak onto the oor and may make the treadmill belt slippery.
