MAINTENANCE & CARE
General cleaning will help prolong the life and performance of your treadmill. Keep the
unit clean and maintained by dusting the components on a regular basis. Clean both
sides of the running belt to prevent dust from accumulating underneath the belt. Keep
your running shoes clean so that dirt from your shoes do not wear out the running board
and belt. Clean the surface of the running belt with a clean damp cloth.
To better maintain the treadmill and prolong its life it is suggested that the machine be
powered off for 10 minutes every 2 hours and fully powered off whenever not in use.
A loose Running Belt will result in the runner sliding off when running, while too tight of
a Running Belt will result in decrease to the motors performance and also create more
friction between the roller and running belts. The most suitable tightness for the belts is
pulled out 50-75mm from the Running Board.
CENTERING THE RUNNING BELT:
Place the treadmill on level ground and set it at 3-5mph to check if the Running Belt
(C11) drifts.
1. If the Running Belt (C11) moves to
the right, turn the adjusting bolt on the
right side ¼turn clockwise, then turn
the left adjustment bolt ¼ turn
counter-clockwise. If the belt does not
move, repeat this step until it centers.
Refer to Figure A.
2. If the Running Belt (C11) moves to
the left, turn the adjusting bolts on the
left side ¼of a turn clockwise, then
turn the right adjustment bolt ¼ turn
counter-clockwise. If the belt does not
move, repeat this step until it centers.
Refer to Figure B.
3. Over time the Running Belt (C11)
will loosen. To tighten the belt turn the
Left & Right side adjustment bolts one
full turn clockwise, check the tension
of the belt. Continue this process until
belt is at the correct tension. Make
sure to adjust both sides equally to
ensure correct belt alignment. Refer to
diagram “C”.

13
LUBRICATING THE TREADMILL
*IMPORTANT NOTE:
You will need to lubricate your treadmill before the first use.
RUNNING BELTS & TREADMILL LUBRICANT:
Lubricating the running board and running belt is essential as the friction between the
two affects the life span and function of the treadmill, therefore it is suggested that the
running board and belt be inspected regularly. Should you find any wear on the Running
Board, please contact us at: [email protected].
WARNING: Always unplug the treadmill from the electrical outlet before cleaning,
lubricating or repairing the unit.
HOW TO LUBRICATE:
1. Raise the belt up on one side and apply lubricant to the running deck. Use a rag to
thoroughly wipe the lubricant over the running deck. Repeat this process for the other
side.
2. The moving parts should turn freely and quietly. Abnormality of moving parts will
affect the safety of the equipment. Inspect and tighten bolts regularly.
3. To better maintain the treadmill and prolong its lifespan, it is suggested that
maintenance be done on a regular basis.
4. A loose running belt will result in the runner sliding off during use, while too tight of a
running belt will decrease the motor performance and also create more friction between
the roller and running belts. The most suitable tightness for the belt is pulled out
50-75mm from the Running Board.
The following time table is recommended:
Light user (less than 3 hours/ week) every six months
Medium user (3-5 hours/ week) every three months
Heavy user (more than 5 hours/ week) every two months

FOLDING INSTRUCTIONS
FOLDING:
UNFOLDING:
Place your hand at position
“D” and lift the Main Frame
(A02) up until the Air
Pressure Cylinder (B06) “C”
locks into the tube.
When the Air Pressure
Cylinder (B06) successfully
locks into the tube, you will
hear a clicking sound.
Before lowering the Main
Frame (A02), ensure that the
space directly underneath it is
clear of any objects.
Grasp the Main Frame (A02)
at position “D” with one hand.
Next, using your foot, firmly
push against the Air Pressure
Cylinder (B06) “C” and press
down on the Main Frame
(A02). Once the Main Frame
(A02) has been pushed down,
it will automatically continue to
steadily lower itself until it
reaches the ground.

15
HOW TO MOVE THE MACHINE
Before attempting to move the
treadmill, please make sure
that it has been properly
folded. Unplug power cord.
Start by placing one hand at
position “D”to support the top
end of the treadmill. Next,
place one foot at position “E”to
hold the bottom end of the
treadmill steady. With your
foot at “E”, slowly tilt the top of
the treadmill downward
towards the ground. Once the
Main Frame (A02) reaches a
low enough point, the wheels
of the treadmill will touch the
ground.
To transport, hold the treadmill
from position “D”and tilt until the
wheels “E”are able to move on
the ground.

that the power source is correct before plugging the equipment. Any power source above
or below this level could cause significant damage to the equipment and or user.
GROUNDING METHODS:
This product must be grounded. Grounding provides the least resistance for electrical
current and will reduce the risk of electric shock. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance with all local
codes and ordinances. Ensure that the product is connected to an outlet which contains
the same configuration as the plug. Do not use an adaptor for this product.

looks like the plug illustrated in sketch A. Make sure that the product is connected to an
outlet having the same configuration as the plug. No adapter should be used with this
product.
DANGER:
Improper connection of the equipment-grounding conductor can result in risk of electric
shock. Check with a certified electrician if you are in doubt as to whether the product is
properly grounded. Do not modify the plug provided with the product. If it will not fit the
outlet, have a proper outlet installed by an electrician.
WARNING!
1. NEVER use a ground fault circuit interrupt (GFCI) wall outlet with this treadmill. Route
the power cord away from any moving part of the treadmill including the elevation
mechanism and transport wheels.
2. NEVER operate the treadmill using a generator or UPS power supply.
3. NEVER remove any cover without first disconnecting AC power.
