The E5 SI is an elliptical exercise machine distributed by NordicTrack. It is designed to be a low-impact alternative to treadmills, simulating walking and running with less stress to joints. While some elliptical models work only the lower-body, most modern designs, including the E5 SI, work both upper- and lower-body. A study by the University of Idaho suggests that an elliptical trainer can affect a larger group of muscles than traditional treadmills, jogging and walking. Regular inspection and maintenance can help keep the NordicTrack E5 SI in safe operating condition.
Things You'll Need
- Soft cloth
- Allen wrench
- 1.5V "D" batteries, four
Replace the batteries if the console display is dim or malfunctions. Unsnap the battery cover on the top of the console. Insert four 1.5V "D" alkaline batteries according to the directional insertion arrows within the console. Re-attach the battery cover, pressing firmly until it snaps back into place.
Clean the hand-grip pulse sensors if the unit fails to detect a heartbeat. Wipe the metal contacts of the hand-grips with a soft cloth. Never use alcohol, abrasives or chemicals on the hand-grips.
Loosen the bolts on top and below the shield if the discs are rubbing together. Locate the two 25 mm bolts on top of the shield and loosen them a quarter-turn with an Allen wrench. Locate the two 19 mm screws on the base below the shield and loosen them a quarter-turn with a screwdriver.
