LUBRICATING THE TREADMILL
IMPORTANT NOTE:
You will need to lubricate your treadmill before the first use.
RUNNING BELT & TREADMILL LUBRICANT:
Lubricating the Running Board (No. E18) and Running Belt (No. C22) is essential as the friction
affects the life span and operations of the treadmill. Inspect the Running Belt (No. C22) and Running
Board (No. E18) regularly. If you find any wear on the Running Board (No. E18), 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. To apply lubricant, lift one side of the Running Belt (No. C22) and apply oil to the middle of the
Running Board (No. E18). Next, start the treadmill and place it at the lowest speed setting and allow
the oil to spread over the Running Board (No. E18). Repeat this process for the other side.
2. The moving parts should turn freely and quietly. Abnormal 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. DO NOT LOOSEN OR MAKE ANY ADJUSTMENTS TO THE RUNNING BELT WHILE APPLYING
LUBRICANT. A loose Running Belt (No. C22) will result in the runner sliding off during use, while
too tight of a Running Belt (No. C22) will negatively affect the motor’s performance and create more
friction between the roller and Running Belt (No. C22). The most suitable tightness for the Running
Belt (No. C22) is when it is pulled out 50-75mm from the Running Board (No. E18).
The following timetable 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

10
HOW TO FOLD THE MACHINE
STEP 1:
Pull out the Tablet Holder Fixed Base (No.
C19) from Console Rear Cover (No. C14).
STEP 2:
Loosen the 2 Puller Bolts B (No. B10) inside
the Console Base Bracket (No. A04) by
turning counter-clockwise using the Allen
Wrench (No. B03).
Lift the Console Base Bracket (No. A04)
upward (in the direction specified by the arrows
on the diagram to the left).

11
STEP 3:
Support the Left & Right Upright Tubes (No.
A02 & No. A03) with your hands to prevent
them from falling.
Loosen the 2 Puller Bolts A (No. B09) inside
Left & Right Upright Tubes (No. A02 & No.
A03) by turning counter-clockwise using the
Allen Wrench (No. B03).
STEP 4:
Pull the Console Base Bracket (No. A04)
along with Left & Right Upright Tubes (No.
A02 & No. A03) downward (in the direction
specified by the arrows on the diagram to the
left).

12
HOW TO MOVE THE MACHINE
Hold the treadmill at position as above with your hand. Lift the treadmill and
then you can move the treadmill to any place.

13
HOW TO ADJUST THE BALANCE
When the height of each pad or because of individual machine placed on the ground is not even,
you need to adjust the Adjustable Pads (No. C31) to level the machine on the ground.
Adjustment method: First, place the machine as shown above, use Spanner w/ Screwdriver
(No. B21), and adjust the Adjustable Pads (No. C31) clockwise to raise the footpad and counter-
clockwise to lower the footpad. When you have finished adjusting the base leveler, re-tighten the
first Nut (look down from the top) of Adjustable Pads (No. C31) clockwise by using Spanner
w/ Screwdriver (No. B21). If needed, repeat this process to adjust the remaining base levelers.

14
MAINTENANCE & CARE
General cleaning will help prolong the life and improve the performance of your treadmill. Keep the unit
clean and maintained by dusting the components on a regular basis. Cleaning two exposed sides of
the Running Belt (No. C22) will prevent dust from accumulating underneath. Keep your running shoes
clean so that dirt from your shoes does not wear out the Running Board (No. E18) and Running Belt
(No. C22). Clean the surface of the Running Belt (No. C22) with a clean damp cloth.
To better maintain the treadmill and prolong its life, it is suggested that the treadmill be powered off for
10 minutes every 2 hours and fully powered off whenever not in use.
CENTERING THE RUNNING BELT:
Place the treadmill on level ground and set it at 3-5MPH to check if the Running Belt (No. C22) drifts
from the center.
If the Running Belt (No. C22) moves to the
right, turn the right adjusting bolt ¼ turn
clockwise, then turn the left adjusting bolt ¼
turn counter-clockwise. If the Running Belt
(No. C22) does not move, repeat this step
until it centers. Refer to Figure A.
If the Running Belt (No. C22) moves to the
left, turn the left adjusting bolt ¼ turn
clockwise, then turn the right adjusting bolt ¼
turn counter-clockwise. If the Running Belt
(No. C22) does not move, repeat this step
until it centers. Refer to Figure B.
Over time, the Running Belt (No. C22) will
loosen. To tighten the Running Belt (No.
C22), turn the left & right adjusting bolts one
full turn clockwise, check the tension of the
Running Belt (No. C22). Continue this
process until Running Belt (No. C22) is at
the correct tension. Make sure to adjust both
sides equally to ensure correct belt
alignment. Refer to Figure C.

before plugging in 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 a path of the least resistance for electrical current
to 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 adapter for
this product.
This product is for use on a nominal 100-120V circuit and has a grounding plug that looks like the plug
illustrated in sketch A.
DANGER:
Improper connection of the equipment can result in risk of electric shock. Check with a qualified
electrician or serviceman if you are unsure whether the product has been properly grounded. Do not
modify the plug provided with this product. If it will not fit the outlet, have a proper outlet installed by a
qualified electrician.
WARNING!
1. NEVER use a ground fault circuit interrupt (GFCI) wall outlet with this treadmill. Route the power
cord away from all moving parts of the treadmill, including the elevation mechanism and
transportation wheels.
2. NEVER operate the treadmill using a generator or UPS power supply.
3. NEVER remove any cover on the treadmill without first disconnecting power cord.
