8. Make sure that there is safe clearance around, on and above the tread-
mill. 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.
9. 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.
10. Make sure that the locking mechanism is engaged. Carefully pull
back on the walking deck and make sure that it does not move. When
you do this, keep clear of movement path in case the treadmill lock is not
engaged.
Do not lean against the treadmill when it is folded. Do not put items
on it that could cause it to become unstable or fall.
11. Remove the Base Shrouds from the Base Assembly.
