5. Using a #2 Phillips screwdriver, remove the two indicated screws (with
arrows) from the Deck Wheel Shroud.
6. Using a 13mm wrench and a 6mm hex wrench, remove the hardware
indicated (by the oval) from the Deck Wheel.
7. Re-install all remaining parts that were removed in reverse order.
8. 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.
9. Make sure there is no object on or around the treadmill to spill or cause
blockage from the fully unfolded position.
10. 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 console.
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.
11. 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.
12. Final Inspection
Inspect your machine to ensure that all hardware is tight and components
are properly assembled.
Do not use until the machine has been fully assembled and
inspected for correct performance in accordance with the
Owner's Manual.
