How To...Adjust the Lift Actuator
Special Service Tools Required: NONE
1. Verify that the home switch is functioning. Enter into
Diagnostics (see Section 2). Select Incline Manual. A “0”
should appear in the lower right corner of the Profile
Window when activated. Also the Wax/Lift LED 4 and 5 will
be lit when home switch is activated. If not, then proceed to
next step.
2. Drive the Lift System down until the actuator's internal limit
switch stops the lift function. Disconnect power from the
treadmill.
3. Measure and record the space between the top of the lift
wheels and bottom of the unit frame.
4. Turn the treadmill over on its side.
5. Remove the 3/8-16 nut and bolt from the Lift Arm
Weldment.
6. Turn the actuator tube clockwise (in towards the motor) in
half-turn increments to approximately equal the space
measured in Step 3. One-half turn of the actuator tube
shortens the operating length by 1/16”. Make sure the bolt
holes align.
Example: If the space between the top of the wheel and the
bottom of the frame is 3/16”, turn the actuator tube 1-1/2 turns
clockwise (in towards the motor). If the space is 5/32”, turn the
actuator tube 1 turn clockwise.
IMPORTANT: Be careful not to turn the actuator screw while
turning the actuator tube.
7. Install the Actuator tube back into the Lift Arm weldment and
secure with nut and bolt.
8. Verify orientation of switch so that the terminal connector is
facing toward the Frame Tag PCB. If backward, remove and
reinstall to proper orientation as shown.
9. Turn the treadmill over and restore power.
10. Test the lift function in a user program. Note: If necessary,
balance the unit and adjust striding belt tracking.
