Service Instruction

!WARNING: All maintenance activities shall be performed by qualified personnel. Failure to do so could result in serious injury.

These activities should be performed at the recommended intervals listed in the Service Schedule in the Preventive Maintenance chapter:

Measure the motor brushes and replace worn motor brushes Rotate, flip and replace the running deck.

Replace the running belt Check the current draw

Measure motor voltage at maximum speed, with no load

See the detail procedures for each of these maintenance activities below.

Motor Brushes

!WARNING: Motor brush removal and replacement should be performed by a qualified service technician.

Cybex treadmill motors are of the DC variety, and thus have brushes in them to transfer power to the motor's armature. These brushes are made of a graphite / carbon compound not too unlike pencil lead. They do wear with use, and should be inspected at 15,000 miles (16898 km) and every 15,000 (16898 km) after (or sooner if your didn’t replace them at the last inspection). Measure the length of the brush itself, and don't include the spring, cable, or spring mount post on the top of the brush. Brushes should be replaced when they are measured to be 7/16” (11mm) or less.

NOTES: Motor brushes are wear items that will periodically need to be replaced. Both drive motor brushes must be replaced as a pair. This will ensure even commutator contact and brush wear. However, the negative brush will wear 20% faster than the positive brush. Therefore, always measure the negative brush length to determine whether you should replace the pair. The negative brush has a white lead and is facing the floor. You should still check the positive brush for cracks or chips.

It is not necessary to remove the drive motor in order to reach the motor brushes. You can get at the lower brush from underneath the treadmill.

Tools Required

•Phillips head screwdriver (or hex key for some models)

•Large flat head screwdriver (or brush cap tool, part number FS-12263)

•Tape measure
