12. Using a 6mm hex wrench, remove the hardware from the Left Upright.
Be prepared to support the Upright when the hardware is removed.
13. Using a 6mm hex wrench, remove the hardware from the Right Up-
right. Slightly remove the Right Upright from the Base Assembly exposing
the Input/Output (I./O) Cables. Disconnect the I/O Cables and remove the
Right Upright.
Note: do not crimp cables.
14. Make sure there is sufficient space to lower the walking deck.
Keep a minimum clearance behind the machine of 2 m (79") and
0.6 m (24") on each side. This is the recommended safe distance
for access, movement and emergency dismounts from the
machine.
15. Make sure there is no object on or around the treadmill to spill or
cause blockage from the fully unfolded position.
16. Slightly push the walking deck forward toward the console. With your
foot lightly push the top part of the hydraulic lift forward until the locking
tube releases and you can pull the walking deck away from the con-
sole. Hold up the rear of the walking deck, and move to the side of the
machine.
Keep clear of the movement path of the walking deck.
17. The hydraulic lift is set up to drop gradually. Hold onto the walking
deck until approximately 2/3 of the movement down. Make sure that
you use proper lifting technique; bend your knees and keep your back
straight. Be aware that the walking deck can possibly drop quickly in the
last part of the movement.
