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.
C09)to prevent dust from accumulating underneath the belt. Keep your running shoes clean so that
dirt from your shoes does not wear the Running Board (No. D09) and Running Belt (No. C09).
Clean the surface of the Running Belt (No. C09)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 4 mph to check if the Running Belt (No. C09) drifts
from the center. Use Allen Wrench (No. B04) to adjust.
1. If the Running Belt (No. C09)drifts
to the right, turn the right adjusting bolt
¼turn clockwise
, then turn the left
adjustingbolt¼ turncounter-clockwise.
If the Running Belt (No. C09)does not
move, repeat this step until it centers.
Refer to Figure A.
2. If the Running Belt (No. C09)drifts
to the left, turn the left adjusting bolt ¼
of a turn clockwise, then turn the right
adjustingbolt ¼ turn counter-clockwise.
If the Running Belt (No. C09)does not
move, repeat this step until it centers.
Refer to Figure B.
3. Over time the Running Belt (No.
C09)willloosen. To tightenthe running
belt turn the Left & Right adjusting
bolts one full turn clockwise, check the
tension of the
Running Belt (No.
C09)
. Continue this process until
Running Belt (No. C09)
is at the
correct tension. Make sure to adjust
both sides equally to ensure correct
belt alignment. Refer to diagram
“C”
.

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. D09) and Running Belt (No. C09)is essential as the friction
between the two affects the life span and operations of the treadmill. Inspect the Running Board (No.
D09) and Running Belt (No. C09)regularly. If you find any wear on the Running Board (No. D09),
please contact us at: [e-mail].
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. C09) up on one side and apply lubricant to the Running Board (No.
D09). Use a rag to thoroughly wipe the lubricant over the Running Board (No. D09). 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 all 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. C09) will result in the runner sliding off during use, while
too tight of a Running Belt (No. C09) will negatively affect the motor performance and also create
more friction between the roller and Running Belt (No. C09). The most suitable tightness for the
Running Belt (No. C09) is when it is pulled out 50-75mm from the Running Board (No. D09).
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
