PROBLEM: The power turns off during use

SOLUTION: a. Check the circuit breaker located on the treadmill frame near the power cord (see 1. c. above). If the circuit breaker has tripped, wait for five minutes and then press the switch back in.

b. Make sure that the power cord is plugged in.

c. Remove the key from the console. Reinsert the key fully into the console. (See step 1 on page 8.)

d. If the treadmill still will not run, please call our toll-free HELPLINE.

PROBLEM: The displays of the console do not function properly

SOLUTION: a. Check the batteries in the console. See BATTERY INSTALLATION on page 8. Most problems are the result of drained batteries.

b. Remove the six screws from the hood. Carefully re- move the hood. Locate the Reed Switch (86) and the Magnet (87) on the left side of the Pulley (85). Turn the Pulley until the Magnet is aligned with the Reed Switch. Make sure that the gap between the Magnet and the Reed Switch is about 1/8”. If nec- essary, loosen the Screw (35) and move the Reed Switch slightly. Retighten the Screw. Re-attach the hood, and run the treadmill for a few minutes to check for a correct speed reading.

PROBLEM: The walking belt slows when walked on

SOLUTION: a. Use only a single-outlet surge suppressor that is UL 1449 listed as a transient voltage surge sup- pressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules. The surge suppressor must be electrically rated for 120 volts AC and 15 amps.

b. If the walking belt is overtightened, treadmill perfor- mance may decrease and the walking belt may be permanently damaged. Remove the key and UN- PLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjustment bolts counterclock- wise, 1/4 of a turn. When the walking belt is properly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened.
