GROUNDING METHODS
This product power must be grounded. Should the treadmill malfunction or breakdown,
grounding provides a path with the 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.
DANGER –Improper connection of the equipment-grounding conductor can result in a risk of
electric shock. Check with a qualified electrician or serviceman if you are in doubt as to
whether the product is 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.
This product is for use on a nominal 110-volt circuit and has a grounding plug that looks like
the plug illustrated in sketch A in following figure. Make that the product is connected to an
outlet having the same configuration as the plug. No adapter should be used with this product.

11
MAINTENANCE AND ADJUSTMENTS
Warning: ALWAYS UNPLUG THE TREADMILL FROM THE ELECTRICAL OUTLET
BEFORE CLEANING OR SERVICING THE UNIT.
Warning: Always unplug the treadmill from the electrical outlet before removing the
motor cover. At least once a year remove the motor cover and vacuum under the motor
cover.
RUNNING BELT AND DECK LUBRICATION
This treadmill is equipped with a pre-lubricated, low maintenance deck system. The belt/ deck
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 deck. You need contact with our
service center if you find the damage of the deck.
We recommend lubrication of the deck according to the following timetable:
➢Light user (less than 3 hours/ week) annually
➢Medium user (3-5 hours/ week) every six months
➢Heavy user (more than 5 hours/ week) every three months
Attention:
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 to prevent dust from accumulating underneath the belt. Keep your running shoes
clean so that dirt from your shoes do not wear out the running board and belt. Clean the
surface of the running belt 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 will result in the runner sliding off when running, while too tight of a
Running Belt will result in decrease to the motors performance and also create more friction
between the roller and running belts. The most suitable tightness for the belts is pulled out
50-75mm from the Running Board.

12
CENTERING THE RUNNING BELT
Place the treadmill on level ground and set it at 6-8 mph to check if the Running Belt drifts.
If the belt drifts to the right, turn off the switch first, turn
the right adjusting bolt 1/4 turn clockwise, then turn the
left adjusting bolt 1/4 turn counter-clockwise until the
belt is centered. Refer to PIC –A.
If the belt drifts to the left, turn off the switch first, turn the
left adjusting bolt 1/4 turn clockwise, then turn the right
adjusting bolt 1/4 turn counter-clockwise until the
belt is centered.. Refer to PIC –B.
Over time, the belt will loosen. To tighten the belt, turn
both the left & right side adjustment bolts one full turn
clockwise. Check the tension of the belt. Continue this
process until belts is at the correct tension. Make sure to
adjust both sides equally to ensure even belt alignment.
Refer to PIC –C.
