6. Calibrate the elevation motor.
A. The switch should be at zero elevation
before adjusting the tube nut. If necessary
connect the elevation motor, bring the
elevation up to 1% incline and then back
down to 0%.
B. Turn the tube with your fingers until it
measures 12.517" (31.8 cm) from the
center of the top hole to the center of the
bottom hole. See Figure 20.
7. Secure the elevation motor.
A. Carefully place the elevation motor in
position on the treadmill. See Figure 20.
B. Slide both bolts into the slots before
tightening. See Figure 20. NOTE: The top
bolt goes from the left to the right. It
doesn't matter which way the bottom bolt is
positioned.
C. Using a 9/16" open end wrench and a 9/16" socket wrench, securely tighten the nuts and
two bolts installed in step 7B.
D. Connect the elevation motor cable to the lower board. NOTE: The board is labeled P3 at the
elevation port. The connector can only fit in one direction.
E. Place the lower board shield in position and push the clips down. NOTE: The clips will
snap in.
F. Tie the elevation cable with the tie from step 4B so that it is clear of the motor fan. Be sure
no wires get pinched.
8. Test the elevation motor.
A. Connect the main power cord into the power outlet and turn the power switch on (I).
B. Start the treadmill in Manual Mode and raise the elevation to 6%.
C. Carefully remove the wooden blocks from under the front end assembly. This will load the
elevation assembly.
D. Lower the elevation to zero percent.
E. Stop the treadmill and turn the main power switch in the front panel to the off (O) position.
9. Secure the motor cover.
A. Lower the motor cover center into position. See Figure 2.
B. Using a Phillips head screwdriver, tighten the three screws on each side. NOTE: Be sure
the screws are catching the center motor cover's holes.
