⇒ HEARTRATE MODE OPERATION
Start with the Life Fitness Model 5500HR Treadmill turned OFF at the ON/OFF switch.
Power up the unit while holding the INCLINE DOWN KEY ∇. The Display Console will read Test Mode.
Upon initial entry into the test mode, the left column of the program profile window will have one to two LED’s lit.
The first three LED’s (from the top) of the left column are related to jumpers which are not applicable to any of the
test modes.
The fourth LED from the top indicates the condition of the Opto Speed Sensor. (Normal function of the LED is
that it flashes ON and OFF as the Drive Motor turns during operation).
The fifth LED from the top will inform you if the unit is a 120V or a 220V unit. (When the LED is OFF, the unit is
120V. When the LED is ON, the unit is 220V).
The sixth LED from the top indicates the elevation (Home Switch). When the LED is OFF, the Home Switch is
engaged and the unit is at Zero elevation. When the LED is ON, the Home Switch is disengaged and the unit is
at a non-zero elevation.
The Bottom LED is the Emergency Stop Switch condition. When the LED is ON, the Emergency Stop Switch
is engaged and the unit will operate. When the LED is OFF, the Emergency Stop Switch is disengaged and the
unit will not run.
To test the ELEVATION.
Start with the Treadmill at zero elevation and turned OFF at the ON/OFF switch.

TENSIONING BOLTS are accessible from the holes provided in the END CAPS.
Step 2
Enter the Manual program and run unit for five minutes at 5.0 mph (8.0 kph). DO NOT run on the BELT.
Step 3
Using the speed decrease button ∇, bring the STRIDING BELT speed down to 2 mph (3.2 kph). While walking on
the belt, tightly grasp the HANDRAILS and attempt to stall the STRIDING BELT. If the STRIDING BELT slips,
continue to Step 4. if it does not slip, the tension is correct.
Step 4
Stop the treadmill and alternately turn the STRIDING BELT TENSIONING BOLTS 1/4 turn clock-wise to tension,
NOT exceeding one full turn. (See Tracking (Centering) an Existing or New Striding Belt on previous page.
Repeat Step 3.)
Adjusting/Setting Proper Tension for a New Striding Belt
Step 1
After installation but before tensioning, place two pieces of tape exactly 38 1/2 (38.5) inches apart on both right
and left edges of the striding belt.
Step 2
Alternately tighten the right and left tensioning bolts 1/4 turn
clockwise each until the distance between the tape is 38 3/4
(38.75) inches. This is the equivilent of .65% stretch.
Step 3
Adjust tracking.
NOTE: IT IS EXTREMELY IMPORTANT THAT THE TREADMILL BE CORRECTLY LEVELED PRIOR TO ANY
TRACKING ADJUSTMENTS. AN UNSTABLE UNIT MAY CAUSE STRIDING BELT MISALIGNMENT.
Tracking (Centering) an Existing or New Striding Belt
Step 1

MAINTAIN AN IDEAL BELT TENSION AT THE PIVOT POINT.
CAUTION: DO NOT OVER TIGHTEN THE TENSIONING BOLTS WHILE MAKING BELT ADJUSTMENTS.
OVER TIGHTENING OF BOLTS MAY OVER-STRETCH AND DAMAGE THE STRIDING BELT AS WELL AS
PLACE AN UNNECESSARY LOAD ON THE REAR ROLLER BEARINGS.
If the STRIDING BELT has moved to the right,
turn the right TENSION BOLT 1/4 turn clock-wise
and the left TENSION BOLT 1/4 turn counterclockwise to start the STRIDING BELT tracking
back to the center of the REAR ROLLER.
If the STRIDING BELT has moved to the left, turn
the left TENSION BOLT 1/4 turn clock-wise and the
right TENSION BOLT 1/4 turn counter-clockwise to
start the STRIDING BELT tracking back to the
center of the REAR ROLLER.
Step 3
Repeat adjustments until the STRIDING BELT appears centered. Allow the machine to continue running for
several minutes to observe if the tracking remains stabilized.
