EXERCISE INSTRUCTIONS
GETTING STARTED
Before starting any exercise programs, you should consult your physician to determine if you
have any medical or physical conditions that could put your health and safety at risk or prevent
you from using the treadmill properly. Be aware of your body’s signals. Incorrect or excessive
exercise can damage your health. Stop exercising immediately if you experience any of the
following symptoms: pain, tightness in your chest, irregular heartbeat, extreme shortness of
breath, lightheadedness, dizziness, or feelings of nausea.
Turn on the power switch located next to the power cord. Get to know your treadmill. Before
attempting to use the treadmill take some time to stand alongside it and familiarize yourself with
the controls. Once you feel comfortable to get on, you can stand with your feet on the foot rails
and balance yourself by putting your hands on the handrails.
Next, attach the clip end of the Safety Key (No. 71) to your clothing and insert the magnetic end
of the key into the console. Press the START button to start the treadmill. The machine will start
at the default speed of 0.5MPH. Once you feel comfortable, you may slowly increase the speed.
When you are finished with your exercise, press the STOP button or remove the magnetic end of
Safety Key (No. 71) to stop the treadmill.
SAFETY LOCK
Remove the Safety Key (No. 71) from the console to stop the treadmill immediately. Once the
treadmill reaches a full stop, the window display on the computer will show “---” and the treadmill
will beep. To start the treadmill again, insert the magnetic end of Safety Key (No. 71) into the
console and press START.
POWER OFF
Power to the treadmill can be turned off at any time without risk during or after an exercise.
CAUTION
1. We recommend that you maintain a slow speed at the beginning of a session and hold the
handrails until you become comfortable and familiar with the treadmill.
2. Insert the magnetic end of the safety key into the console and attach the opposite end with
the safety clip to your clothing before beginning your workout. To end your workout, press the
STOP button or remove the safety key. The treadmill will stop immediately.

MAINTENANCE GUIDE
General cleaning will help to 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 the two
exposed sides of the running belt will prevent dust from accumulating underneath the belt. Keep
your running shoes clean so that dirt from the shoes does not wear out the running belt. Clean the
surface of the running belt using a clean damp cloth. Keep liquids away from electrical parts and
running belt.
ADJUSTING THE RUNNING BELT
Place the treadmill on level ground and set it at 3.5-5 MPH to check and see if the Running Belt
(No. 26) drifts from the center. Adjust the Running Belt (No. 26) according to below instructions
with Allen Wrench (No. 12).
2. If the Running Belt (No. 26) drifts to
the left, remove the safety key, turn the
adjusting bolt on the left side 1/4 turn
clockwise, then start running until the belt is
centered. Refer to image B.
1. If the Running Belt (No. 26) drifts to
the right, remove the safety key, turn the
adjusting bolt on the right side 1/4 turn
clockwise, then start running until the belt is
centered. Refer to image A.
3. Over time, the Running Belt (No. 26)
will loosen. To tighten the belt, remove the
safety key, turn both the left & right side
adjusting bolts 1/4 turn clockwise, then
re-start running. 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 even belt
alignment. Refer to image C.

LUBRICATING THE TREADMILL
Lubricating the running belt & running board is essential as the friction affects the life span and
operations on the treadmill. Inspect the running belt regularly. If you find any wear on the running
board, please contact us at [e-mail].
WARNING: Always unplug the treadmill from the electrical outlet before cleaning, lubricating,
or repairing the unit.
The following time table is recommended:
Light user (less than 3 hours/ week) every 2 months
Medium user (3-5 hours/ week) every 45 days
Heavy user (more than 5 hours/ week) every month
NOTE:
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 when not in use.
A loose running belt will result in the runner sliding off when in use, while too tight of a running belt
will result in decrease to the motors performance and also create more friction between the roller
and the running belts. The most suitable tightness for the belt is pulled out 50-75 mm from the
running board.

TROUBLESHOOTING
CODE Description How to troubleshoot
E01
1. Message wire is broken or not
connected well.

reset the IC.
3. If you experience a problem with the power on
the
bottom control board, change the bottom
control board.

1. The wire for the motor is not
connected well or the carbon
brush inside the motor is loose.
