EXERCISE GUIDELINES

WARNING! Before beginning this or any exercise program, you should consult your physician. This is espe-

cially important for individuals over the age of 35 or individuals with pre-existing health problems.

Warming up prepares the body for the exercise by increasing circulation, supplying more oxygen to the mus-

cles and raising body temperature. Begin each workout with 5 to 10 minutes of stretching and light exercise

to warm up. The photos on this page show several forms of basic stretching you may perform before your

workouts. In order to achieve an adequate warm-up, perform each stretch three times.

Moving Instructions

CAUTION! TO AVOID THE RISK OF INJURY, NEVER ATTEMPT TO MOVE THE TREADMILL WHILE

IT IS IN THE UNFOLDED OPERATING POSITION. TO REDUCE THE POSSIBILITY OF INJURY

WHILE LIFTING, BEND YOUR LEGS AND KEEP YOUR BACK STRAIGHT. AS YOU RAISE THE

TREADMILL, LIFT USING YOUR LEGS, NOT YOUR BACK. IN ORDER TO RAISE OR LOWER THE

TREADMILL SAFELY, YOU MUST BE ABLE TO LIFT 45 POUNDS (20KG). IT IS SUGGESTED YOU

ALWAYS USE THE AID OF A SECOND PERSON WHEN MOVING THE TREADMILL.

With the treadmill in the folded locked position (safety latch is engaged), grasp the handrail and place one foot

on the base as shown in the photo below. Next, with a firm grasp on handrail, place one foot on the center of

the base crossbar and carefully tilt the treadmill back until it rolls freely on the wheels. Using extreme caution,

move the treadmill to the desired location. To set the treadmill down, place one foot on the center of the base

crossbar and carefully lower treadmill onto base in resting position. Do not attempt to move the treadmill over

Power Requirements

IMPROPER CONNECTION OF THE EQUIPMENT GROUNDING CONNECTOR CAN RESULT

IN A RISK OF AN ELECTRIC SHOCK. CHECK WITH A QUALIFIED ELECTRICIAN OR

SERVICE MAN 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 ELEC-

TRICIAN.

This treadmill can be seriously damaged by sudden voltage changes in your home’s electrical power. Voltage

spikes, surges, and noise interference can result from weather conditions or from other appliances being turned

on or off. To reduce the possibility of treadmill damage, always use a surge protector (not included) with your

treadmill.

Surge protectors can be purchased at most hardware stores. The manufacturer recommends a single outlet

surge protector with UL 1449 rating as a Transient Voltage Surge Suppressor (TVSS) with UL suppressed

voltage rating of 400V or less and an electrical rating of 120VAC, 15 amps.

This treadmill must be grounded to reduce the risk of electrical shock. Grounding provides a path of least

resistance for electric current should the treadmill malfunction. This treadmill comes with an electrical cord

with an equipment-grounding conductor and a grounding plug. Always plug the power cord into a surge pro-

tector, and plug the surge protector into an appropriate outlet that is properly installed and grounded in accor-

dance with all local codes and ordinances.

This product is for use on a nominal 120-volt circuit and has a grounding plug that looks like the plug illustrat-

ed in the drawing below.

Belt Adjustment

WARNING! Do not over-tighten rollers! This will cause prema-

ture roller bearing failure!

Belt adjustment and tension performs two functions: adjustment for

tension and centering. Your new treadmill comes pre-adjusted from

the factory for tension and centering. Please follow the procedures

below if the belt shifts to the left or right while walking:

WALKING BELT IS SHIFTING TO THE LEFT (Diagram 1)

First, turn treadmill on to run at 1 mph. Using the hex key provid-

ed, turn the left rear roller adjustment bolt ¼ turn in the clockwise

direction. Next, run the treadmill at 2.5 mph. You should see the belt

start to correct itself by moving back towards the center. Repeat the

above procedure until the walking belt is centered. It may be neces-

sary to set walking belt tension once you have completed this proce-

dure if the belt feels like it is slipping while walking. Refer below

to the “Walking Belt Slipping” instructions.

WALKING BELT IS SHIFTING TO THE RIGHT (Diagram 2)

First, turn the treadmill on to run at 1 mph. Using the hex key pro-

vided, turn the right rear roller adjustment bolt ¼ turn in the clock-

wise direction. Next, run the treadmill at 2.5 mph. You should see

the belt start to correct itself, moving back towards the center.

Repeat the above procedure until the walking belt is centered. It

may be necessary to set walking belt tension once you have complet-

ed this procedure if the belt feels like it is slipping while walking.

Refer below to the “Walking Belt Slipping” instructions.

WALKING BELT IS SLIPPING DURING USE (Diagram 3)

First, unplug the power cord from the surge protector. Using the hex

key provided, turn both left and right rear roller adjustment bolts the

same distance, usually a ¼ turn in the clockwise direction. Plug the

power cord back into the surge protector and run the treadmill at 2.5

mph. You should now walk on the belt to determine if the belt is still

slipping. Repeat the above procedure until the walking belt is not

slipping. The tension should be just tight enough not to slip.

Note: Turning the hex key counter clockwise brings the rear

rollers and belt towards you.

Turning the hex key clockwise pushes the rear roller and belt

away form you.

Maintenance Instructions

WARNING! Before performing any maintenance to your treadmill, always unplug the power cord from the

surge protector.

CLEANING

Routine cleaning of your HT502t Fitness treadmill will extend the life of your treadmill. WARNING! To pre-

vent electrical shock, be sure the power to the treadmill is OFF and the unit unplugged from the wall electrical

outlet before attempting any cleaning or maintenance.

AFTER EACH WORKOUT: Wipe off the console and other treadmill surfaces with a clean, water damp-

ened soft cloth to remove excess perspiration. USE NO CHEMICALS.

WEEKLY: Use of a treadmill mat is recommended for ease of cleaning. Dirt from your shoes contacts the

belt and eventually makes it to underneath the treadmill. Vacuum underneath treadmill once a week.

DECK LUBRICATION

The walking belt has been pre-lubricated at the factory. However, it is recommended that the walking board be

checked periodically for lubrication to ensure optimal treadmill performance.

Every 30 days or 30 hours of operation, lift the sides of the walking belt and feel the top surface of the walk-

ing board as far under as you can reach. If you feel signs of silicone, no further lubrication is required. If it

feels dry to the touch, follow the instructions below.

Keys Fitness recommends “Lube N Walk” for cleaning and lubricating the treadmill belt and deck. Ask your

retailer or call Keys Fitness at 888-340-0482. You may also use silicone such as “Napa 8300” (available at

most NAPA Auto Parts stores).

TO APPLY LUBRICANT TO THE WALKING BOARD

1) Position the walking belt so that the seam is located on top and in the center of the center of the walking

board.

2) Insert the spray nozzle into the spray head of the lubricant can.

3) While lifting the side of the walking belt, position the spray nozzle between the walking belt and the board

approximately 6” from the front of the treadmill. Apply the silicone spray to the walking board, moving from

the front of the treadmill to the rear. Repeat this on the other side of the belt. Spray approximately 4 seconds

on each side.

4) Allow the silicone to ‘set’ for one minute before using the treadmill.

WARNING: Do not over-lubricate the walking board. Excess lubricant should be wiped off with a clean

towel.
