HOW TO ADJUST THE BALANCE
To achieve a smooth and comfortable experience, you must ensure that the treadmill is stable. If you
notice that the treadmill is unbalanced during use, you should adjust the Adjustable Foot Pads (No.
C23-2). To do so, use Spanner w/ Screw Driver (No. B03) to loosen Nut (No. C23-1) by turning it
clockwise. With the Nut (No. C23-1) loosened, rotate the Adjustable Foot Pads (No. C23-2) until it
sits level with the surface that the treadmill is on. When you have finished adjusting the Adjustable
Foot Pads (No. C23-2), use Spanner w/ Screw Driver (No. B03) to re-tighten the Nut (No. C23-1) by
turning it counter-clockwise. If required, repeat this process to adjust the remaining feet.

18
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 (No.
C19) to prevent dust from accumulating underneath. Keep your running shoes clean so that dirt from
your shoes does not wear out the Running Board (No. D13) and Running Belt (No. C19). Clean the
surface of the Running Belt (No. C19) 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.
A loose Running Belt (No. C19) will result in the runner sliding off when running, while too tight of a
Running Belt (No. C19) will negatively affect the motor’s performance and also create more friction
between the roller and Running Belt (No. C19). The most suitable tightness for the Running Belt
(No. C19) is pulled out 50-75mm from the Running Board (No. D13).
CENTERING THE RUNNING BELT:
Place the treadmill on level ground and set it at 4-5MPH to check if the Running Belt (No. C19) drifts.
If the Running Belt (No. C19) 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 Running Belt (No. C19)
does not
move, repeat this step until it centers.
Refer to Figure A.
If the Running Belt (No. C19) moves to
the left, turn the adjusting bolts on the left
side ¼ clockwise,
then turn the right
adjustment bolt ¼ turn counterclockwise
. If
the Running Belt (No. C19)
does not
move,
repeat this step until it centers.
Refer to Figure B.
Over time, the Running Belt (No. C19)
will loosen. To tighten the
Running Belt
(No. C19), turn the Left & Right
side
adjustment bolts one full turn clockwise
.
Check the tension of the
Running Belt
(No. C19)
. Continue this process until
Running Belt (No. C19)
is at the correct
tension. Make sure to adjust both sides
equally to ensure correct belt alignment.
Refer to Figure C.

LUBRICATING THE TREADMILL
IMPORTANT NOTE:
You will need to lubricate your treadmill before the first use.
RUNNING BELTS & TREADMILL LUBRICANT:
Lubricating the Running Board (No. D13) and Running Belt (No. C19) is essential as the friction
between the two affects the life span and function of the treadmill. It is suggested that the Running
Board (No. D13) and Running Belt (No. C19) be inspected regularly. Should you find any wear on
the Running Board (No. D13), 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 Running Belt (No. C19) up on one side and apply lubricant to the Running Board (No.
D13). Use a rag to thoroughly wipe the lubricant over the Running Board (No. D13). 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. A loose Running Belt (No. C19) will result in the runner sliding off during use, while too tight of a
Running Belt (No. C19) will negatively affect the motor’s performance and also create more friction
between the roller and Running Belt (No. C19). The most suitable tightness for the Running Belt
(No. C19) is pulled out 50-75mm from the Running Board (No. D13).
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
