What you will need:

Philips screwdriver
15 mm spanner or 6mm hex socket

Turn off the treadmill, remove the safety key and unplug the power cord
Remove the motor cover by unscrewing the 4 retaining screws

Re-tighten (clockwise) all the motor retainer bolts
Reattach the motor cover with the 4 retaining screws
