How To... Adjust Striding Belt Tracking
Tools Required: Hex key wrench set
IMPORTANT: It is CRITICAL that the treadmill
be correctly leveled prior to any tracking
adjustments. An unstable unit can cause
Striding Belt misalignment. To level and
stabilize the unit, refer to instructions on
"How To...Replace The Leveler Assembly" in
this section.
Step 1
After the treadmill has been installed and leveled,
the belt must be checked fo confirm proper
tracking. First, plug the power cord into an
appropriate outlet and turn the treadmill ON.
Step 2
Refer to the SPEED AUTOMATIC test procedure under MOTOR TEST MODULE in DIAGNOSTICS: SYSTEM
TEST to achieve a 4.0 mph (6.4 kph) motor speed.
Step 3
With the belt running, note its tracking. If the belt
moves to the right, turn the right tensioning bolt
1/4 turn counterclockwise to bring the belt back to
center. If the belt moves to the left, turn the left
tensioning bolt 1/4 turn clockwise and then turn
the right tension bolt 1/4 turn counterclockwise to
bring the belt back to center.
If the STRIDING BELT has moved to the right,
turn the right TENSION BOLT 1/4 turn clockwise
and the left TENSION BOLT 1/4 turn counter-
clockwise to start the STRIDING BELT tracking
back to the center of the REAR ROLLER.
Step 4
Repeat this adjustment until the striding belt appears centered. Allow the unit to operate for several minutes to see
that the belt remains centered.
NOTE: During the adjustment above, DO NOT exceed one full turn of the adjusting screws in either direction.
