108
STEP 3:
Remove Plugs (No. 137) from the
Handlebars (No. 3R & No. 3L). Save
the Plugs (No. 137) for later use when
you remove the Handrails (No. 114).
Attach the Handrails (No. 114) to the
treadmill bracket with 4 Screws (No.
75).
Tighten and secure with
Allen
Wrench (No. 20)
.
STEP 4:
Connect the
Power Cord (No. 96) to the
treadmill.
Insert the Safety Key (No. 128) into the
Meter (No. 108).
The assembly is complete!

*IMPORTANT NOTE:
This treadmill does come pre-lubricated, but it is recommended to lubricate your treadmill before
the first use.
RUNNING BELTS & TREADMILL LUBRICANT:
Lubricating the Running Board (No. 24) and Running Belt (No. 25) is essential as the friction
affects the life span and operation of the treadmill. It is suggested that the Running Board (No. 24)
and Running Belt (No. 25) be inspected regularly. If you find any wear on the Running Board (No.
24), 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:
Raise the Running Belt (No. 25) up on one side and apply lubricant to the Running Board (No.
24). Use a rag to thoroughly wipe the lubricant over the Running Board (No. 24). Repeat this
process for the other side. The moving parts should turn freely and quietly. Abnormal moving parts
will affect the safety of the equipment. Inspect and tighten bolts regularly.
To better maintain the treadmill and prolong its lifespan, it is suggested that maintenance be done
on a regular basis. DO NOT LOOSEN OR MAKE ANY ADJUSTMENTS TO THE RUNNING BELT
WHILE APPLYING LUBRICANT. A loose Running Belt (No. 25) will result in the runner sliding off
when in use, while too tight of a Running Belt (No. 25) will decrease to the motor's performance
and also create more friction between the roller and Running Belt (No. 25). The most suitable
tightness for the Running Belt (No. 25) is when it is pulled out 50-75mm from the Running Board
(No. 24).
The following time table is recommended:
Light user (less than 3 hours/week)
Medium user (3-5 hours/week)
Heavy user (more than 5 hours/week)
Lubrication
every six months
every three months
every two months

Folding Instructions
Stand in front of the treadmill. Fold the
Tablet Bracket (No. 4) by pulling it to
the right as shown in drawing A. Then,
turn it down as in the drawing B.
Hold the Handlebars (No. 3L & No.
3R). Press the Foot Lever (No. 115)
until you hear a click. Then, lower the
Handlebars (No. 3L & No. 3R).
Before you fold the treadmill, remove
the 4 Screws (No. 75) and the 2
Handrails (No. 114) using the Allen
Wrench (No. 20).
If you saved the Plugs (No. 137), you
can plug in the holes.

Moving Instructions
Before moving the treadmill, fold the treadmill first. Pull out the Supporting Transportation
Wheels (No. 36) according to the drawing, to ensure the folded treadmill is stable when standing
upright.
To store the treadmill upright, lift the treadmill so it stands vertically. To move the treadmill, tilt the
treadmill towards you until the Transportation Wheels (No. 33) on the front base touch the
ground. Then you can move the treadmill in front and back or left and right directions.

WARNING:
This treadmill requires a power source of 10 amps (100-120V) in order to properly operate. For
your safety as well as the safety of others, please verify that the power source is correct before
powering in the equipment. Any power supply source above or below this level could cause
significant damage to the equipment and/or user.
GROUNDING METHODS:
This product must be grounded. Should the treadmill malfunction or breakdown, grounding
provides a path of least resistance for electric current to reduce the risk of electric shock. This
product is equipped with a plug that has an equipment-grounding conductor and a grounding plug.
The plug must be plugged into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
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. Ensure that the product is connected to an outlet with the same
configuration as the plug. Do not use an adaptor for this product.
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 the 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 any moving parts of the treadmill including the elevation mechanism and
transport wheels.
2. NEVER operate the treadmill using a generator or UPS power supply.
3. NEVER remove any cover on this treadmill without first disconnecting the power cord.

Cleaning
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 (No. 25) will prevent dust from accumulating underneath.
Keep your running shoes clean so that dirt from the shoes does not wear the Running Board (No.
24) and Running Belt (No. 25). Clean the surface of the Running Belt (No. 25) using a clean
damp cloth. Keep liquids away from electrical parts and Running Belt (No. 25). Be careful and
keep all liquids away from the electrical components and underneath the Running Belt (No. 25).
WARNING
Remember to unplug the treadmill from the electrical outlet before removing the motor
cover. Remove the motor cover and vacuum underneath at least once a year.
Running belt and the lubricant oil of the motorized treadmill:
Running Belt (No.25) and Runing Board (No.24) are already pre-lubricated. Running Belt
(No.25) and Runing Board (No.24) friction may play a major role in the function and life of your
treadmill, thus requiring periodic lubrication. We recommend a periodic inspection of the running
board. If the running board is worn out, please contact: [email protected]
We suggest you buy lubricant from local distributors or contact our company directly.
Maintenance Instructions

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.
Adjusting Belt Centering and Tightness:
