3. Use the 

⁵⁄₁₆-inch hex key to turn the wheel lock adjustment key 

clockwise ¼ turn. Refer to Diagram 12. This process realigns the 
center wheel inside the top rail. Leave the 

⁵⁄₁₆-inch hex key in 

place while you tighten the adjustment screws with the 

³⁄₁₆-inch 

hex key.

4. Remove the hex keys and check that the seat no longer rocks 

side-to-side. If the rocking movement continues, you need to 
repeat steps 2 and 3.

If you purchase the optional power adapter, you must also purchase 
the internal cable kit. The kit supplies the cable, bracket, and 
fasteners that connect the power adapter to the lower electronics 
board.

CAUTION: The internal cable kit must be installed by authorized 
service personnel. Do not attempt installation on your own as 
you could void the Precor Limited Warranty. For more 
information, refer to Obtaining Service.

Once the internal cable kit is installed, you can plug the optional 
power adapter into the unit as shown in Diagram 13. Plug the 
opposite end into the appropriate power source for your unit (110/
120v or 220/240v).
