Nautilus® Sport Series Treadmill Service Manual
IMPORTANT SAFETY PRECAUTIONS
13. Never position the treadmill with the back end (direction of 
belt travel) facing a wall or any other objects such as furniture 
or other pieces of fitness equipment. Failure to do so can 
prevent safe exit of the treadmill in an emergency situation 
such as falling. Allow a minimum of 79 inches (2 meters) 
behind the treadmill and 20 inches (.5 meters) on each side. 
14.  Before each use of this equipment, check the power cord, 
plug, plug receptacle and outlet for signs of damage. If any of 
them appears frayed, loose, worn, or otherwise faulty, or if 
the insulation appears worn or cracked, do not operate the 
machine. Position the treadmill so that the wall plug is visible 
and accessible. If the power cord is damaged, it must be 
replaced with a power cord from Nautilus, Inc. 
15.  To avoid potential safety and electrical problems, replace with 
manufacturers’ specified parts only. 
16. Always disconnect the treadmill from the power outlet before 
cleaning, maintaining, servicing, or removing the motor cover. 
17. This equipment is classified Class I, Type B, ordinary 
equipment. Not protected against fluid ingress. Rated for 
continuous operation. Do not operate this equipment in the 
presence of flammable anesthetic mixtures.
18.  Do not let liquid enter the display or motor/controller area. If 
liquid enters either area, the area(s) must be inspected and 
tested for safety by an approved technician before it can be 
used again. Do not place the treadmill near water or outdoors. 
Do not use the machine in damp or wet conditions.
19.  Increased risk due to leakage of electrical current may result if 
this equipment is not grounded properly. 
20. The treadmill must be on an appropriate, dedicated electrical 
circuit carrying 15 amps (110 Volt model) or 7 amps (220 Volt 
model). Nothing else should be connected to the circuit.
21.  Do not stand on treadmill motor cover or front trim cover.
22.  Parents and others in charge of children should be aware that 
children, because of  their natural play instinct and fondness for 
experimenting, may be tempted to situations and behavior for 
which the equipment is not intended, with resulting damage to 
the equipment and injury to the children or others. Children’s 
access to the equipment should therefore be controlled, and 
they should be instructed about the potential for personal injury 
and damage if they play with the equipment.
Failure to follow the conditions set forth below shall limit, to the 
extent allowed by law, Nautilus

reliability, and performance of this equipment.
