f. Move to the opposite side of the treadmill to install the left handrail.
Place the remaining leather pad (rough side facing the side rail
mount) onto the rod and slide the handrail mount onto the rod. See
Diagram 9.
g. Make sure that the 2 washers and 1 thrust bearing are on the T-knob
that you set aside in step 3. To assure proper operation, the thrust
bearing (the one that looks like a washer with ball bearings in it)
must be between the two flat washers. See Diagram 9. Insert the
T-knob and washers into the end of the rod and turn the T-knob so
that it screws into the rod.
Important: If the thrust bearing is not placed between the two flat
washers, the handrail resistance will loosen rapidly during a workout.
With the thrust bearing in its proper position, the resistance between
the T-knobs remains balanced and the handrails maintain a smooth
operation.

tightening the T-knob until you feel an appropriate amount of
resistance when you move the handrail back and forth.
i. Take the remaining locking pin (D) from the hardware kit and place
the wire loop over the T-knob. Align the locking pin hole in the
handrail mount with the side rail and insert the locking pin. See
