7. Make sure that all parts are properly tightened before you use the treadmill. Keep the included allen
wrench in a secure place. The allen wrench is used to adjust the walking belt (see page 27). To protect the
floor or carpet from damage, place a mat under the treadmill.

6. Insert two Handrail Bolts (104) with Handrail Washers
(105) and Handrail Bushings (106) into the right Upright
(99) and the right Handrail Spacer (116). Turn the
Handrail Bushings so they fit against the Upright (see the
inset drawing). Lift the right Handrail (83) slightly and
align the Bolts with the holes in the Handrail. Loosely
thread the Bolts into the Handrail. Do not tighten the
Bolts yet.
See the inset drawing. Remove the Handrail Bolt (104)
used in step 4. Place the other Handrail Spacer (116) on
the left Upright (99), with the cutout toward the treadmill.
Reach inside the left Upright and spread the tabs on the
Grounding Bracket (115) to allow a Bolt to pass through
the Grounding Bracket. Attach the left Handrail (83) as de-
scribed above. Make sure that the Handrail Bushings
(106) are turned properly and that the Bolt goes through
the Grounding Bracket. Tighten all four Handrail Bolts.
Press an Upright Endcap (118) into each Upright.

5. Pull the Upright Wire Harness (119) up through a
Handrail Spacer (116). Place the Handrail Spacer on the
right Upright (99) as shown, with the cutout toward the
treadmill (see inset drawing A).
Connect the Upright Wire Harness (119) to the wires ex-
tending from the Console Base (80). Insert the connec-
tors and the Upright Wire Harness into the hole in the
Console Base (see inset drawing B).
Set the Handrail (83) on the Handrail Spacer (116), being
careful not to pinch the Upright Wire Harness (119).

4. See drawing 4a. While another person holds the
Handrails (83), thread Handrail Bolts (104) two to three
turns into the indicated holes in each Handrail. Then, re-
move the Handrail Bolts.
See drawing 4b. Pinch the tabs on the Grounding Bracket
(115) so that the tabs will fit into the indicated hole in the
left Upright (99). Then, insert the Grounding Bracket into
the hole as far as possible.
Note: It may be helpful to set the Handrails (83) on the
Uprights (99) and loosely thread a Handrail Bolt (104)
into the left Upright and the left Handrail. Tip the
Handrails, if necessary, to thread in the Bolt. Have an-
other person support the Handrails while you complete
the remaining steps. 99
