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.
5) to prevent dust from accumulating underneath the Running Belt (No. 5). Keep your running shoes
clean so that dirt from your shoes does not wear out the Running Board (No. 6) and Running Belt
(No. 5). Clean the surface of the Running Belt (No. 5) 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 (No. 5) will result in the runner sliding off when running, while too tight of a
Running Belt (No. 5) will negatively affect the motor’s performance and also create more friction
between the roller and Running Belt (No. 5). The most suitable tightness for the Running Belt (No. 5)
is pulled out 50-75mm from the Running Board (No. 6).
CENTERING THE RUNNING BELT:
Place the treadmill on level ground and set it at 3-5mph to check if the Running Belt (No. 5) drifts.
1. If the Running Belt (No. 5) 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. 5) does not move, keep
adjusting ¼ turn at a time until it
centers. Refer to Fig. A.
2. If the Running Belt (No. 5) 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
Running Belt (No. 5) does not move,
keep adjusting ¼ turn at a time until it
centers. Refer to Fig. B.
3. Over time the Running Belt (No. 5)
will loosen. To tighten the Running
Belt (No. 5) turn the Left & Right side
adjustment bolts one full turn
clockwise, check the tension of the
Running Belt (No. 5). Continue this
process until Running Belt (No. 5) is
at the correct tension. Make sure to
adjust both sides equally to ensure
correct Running Belt (No. 5)
alignment. Refer to Fig. C.

LUBRICATING THE TREADMILL
*IMPORTANT NOTE:
You will need to lubricate your treadmill before the first use.
Lubricating the Running Board (No. 6) and Running Belt (No. 5) is essential as the friction between
the two affects the life span and function of the treadmill. Inspect the Running Board (No. 6) and
Running Belt (No. 5) regularly. Should you find any wear on the Running Board (No. 6), 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. 5) up on one side and apply lubricant to the Running Board (No. 6).
Use a rag to thoroughly wipe the lubricant over the Running Board (No. 6). 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 (No. 5) will result in the runner sliding off during use, while too tight of a
Running Belt (No. 5) will negatively affect the motor’s performance and also create more friction
between the roller and Running Belt (No. 5). The most suitable tightness for the Running Belt (No. 5)
is pulled out 50-75mm from the Running Board (No. 6).
The following time table is recommended:
Light user (less than 3 hours/ week) every five months
Medium user (4-7 hours/ week) every two months
Heavy user (more than 7 hours/ week) every one months
