To reduce the risk of electrical shock or unsupervised usage of the equipment, always unplug the power cord from the
!
wall outlet and wait 5 minutes before cleaning, maintaining or repairing this machine. Place the power cord in a secure
location.
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
indicated Adjustment 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 securing screw just below
the Adjustment Bolts 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, push the
Deck Release Handle and 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
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.
