and the machine and wait 5 minutes before cleaning, maintaining or repairing the machine. Place the power cord in a secure
location.
Note: The Nautilus™ T626 is used in the following images. The procedure
is the same for the Nautilus™ T624/T684/T686 and Schwinn
models.
1. Unplug the power cord from the machine and wait 5 minutes. Place the
power cord in a secure location.
2. Using a 6mm hex wrench, loosen the Walking Belt by turning the Ad-
justment Bolts found on both Rear Roller Covers. Loosen until the Walking
Belt can be slid by a hand on the belt.
Note: be sure to record the number of turns of the Adjustment Bolts it
takes to loosen the Walking Belt. This will assist with reassembly.
3. Using a #2 Phillips screwdriver, remove the indicated screw from the
Rear Roller Covers.
4. Make sure that there is safe clearance around, on and above the
treadmill. Make sure there is no object to spill or cause blockage from the
fully folded position.
Be sure there is adequate height clearance for the raised deck.
5. Using the support bar found below the rear of the walking belt, lift the
walking deck fully upward and engage the hydraulic lift. Be sure that the
hydraulic lift is correctly locked in place. You will hear an audible click
when the hydraulic lift shifts into the locked position.
Use proper safety precautions and lifting techniques. Bend your
knees and elbows, keep your back straight and pull up equally with
both arms. Make sure that your own physical strength is capable of
lifting the walking deck until it engages the locking mechanism. Use
a second person if necessary.
Do not use the walking belt or rear roller to lift the treadmill. These
parts do not lock in place and can abruptly move. Injury to you or
damage to the machine can occur.
6. Make sure that the locking mechanism is engaged. Carefully pull back
