4 SERVICE AND TECHNICAL DATA

4.1 PREVENTATIVE MAINTENANCE TIPS

Use a vacuum cleaner or a slightly damp cloth to remove dust from the treadmill periodically.

WARNING: Do not use any solvents on the deck or running belt, as these can reduce lubrication.

Also, fold up the treadmill and vacuum the floor beneath and around it periodically to prolong the life of the unit.

4.2 WHEN AND HOW TO OBTAIN PRODUCT SERVICE

IDENTIFYING PROBLEMS

In the event of an electrical failure, the treadmill shuts down immediately.

Generally speaking, if the console’s displays or programs do not function properly, try switching it off and on. Doing

so often clears problems by resetting the treadmill computer’s memory. If restarting the treadmill does not eliminate

the problem, call Customer Support.

• No signal on the monitor LCD windows: It is often possible to correct this problem by restarting the tread-

mill. If not, check the communication cable between the monitor and motor controller, and make sure that the

cable isn’t pinched or damaged.

• Displayed “ERROR 1-SPEED SENSOR ERROR”: This indicates that the computer is not picking up the

motor speed signal. Note whether the belt moves at all when the START key is pressed. If so, note whether the

motor stops at low speeds, such as 0.5 mph to 1 mph (1.0kmh to 1.5 kmh) or high speeds, such as 6 mph to

8 mph (10kmh to 12 kmh). These details are important in helping Customer Service diagnose and solve the

problem.

• Displayed “ERROR 2-OVER SPEED ERROR”: This problem actually is a safety function referred to as “run

away protection”. When the belt speed exceeds the computer’s speed detection range, the treadmill motor

shuts down, and the MESSAGE CENTER displays the Error 2 message. In this case, simply restart the

treadmill. If the MESSAGE CENTER displays this message before the unit is ever used, or if the MESSAGE

CENTER displays this message at speeds within the detection range, the mechanism is damaged.

• Displayed “ERROR 3-SAFETY KEY TETHER ERROR”: This indicates that the Emergency Stop Key is not

correctly inserted into the keyholder. Make sure that the key is properly inserted.

• Displayed “ERROR 5-INCLINE ERROR”: This indicates that the incline motor, which creates workout ele-

vations, is not functioning properly. It may be over-loaded or over-heated. To test this, wait until the motor

cools down, and try working out again. Other sources of the problem may be that the sensor connection

cable is defective, the sensor itself may be damaged, or the incline motor itself is damaged.

• Displayed “ERROR 11-COMMUNICATION ERROR”: It is often possible to correct this problem by restart-

ing the treadmill. If not, check the communication cable between the monitor and motor controller, and make

sure that the cable isn’t pinched or damaged.
