Motors are especially susceptibletodust and dirt, and
restricted airflow can prevent adequate cooling that could shorten
motor life.

To

clean the motor components, you must remove the

two

Phillips head

screws that hold the motor cover

in

place. Lift the cover, and put it and the

screws aside. Use a vacuum attachment or hand vacuum

surrounding areas.

Also use a dry cloth for the areas that you canIt reach with the vacuum cleaner. If the

machine has not been used for some time or is excessively dirty, use a dry cloth to wipe
all

exposed areas. Replace the cover and screws when finished.

Four Times Per Year - Clean the belt and the deck surfaces to minimize the effect of

friction between the wood deck and the running belt. Clean the underside of the running
belt and the top of the running deck surface by wiping them with a clean dry towel.This
should be done four times per year to prevent premature wear of the deck, running belt,
and the drive motor system.

As

Needed - The running belt may become loose and slip

on

the drive roller with each

foot plant.

To

Re-tension the Belt: While holding down any key

on

the console, turn the treadmill on;

this brings you into Test Mode. Press Speed

...

to increase the belt speed to 5 mph

(8

kph). Rotate bothofthe rear roller tension bolts 1/4ofa turn clockwise. If the belt
tracks off center, to either side, the running deck will become visible. If this occurs, it will
be necessary to adjust the running belt back to the center. See Figure

1.

Figure 1

! CAUTION: Be careful not to over tighten the belt. Over tightening the belt can

create excessive tension

on the front

and

rear rollers.

To

Re-center the Belt: Use a wrench to tighten the rear roller bolt on the side of the

treadmill towards which the belt

is

moving. For example: If the belt moves to the right and
the deck becomes exposedonthe left, use a wrench to tighten the rear roller bolt on the
right side

of

the frame, tighten about 1/2 of a turn (clockwise) and wait 30 seconds. If the

belt does not move back to the center

of

the treadmill, make another adjustment to the
same bolt. Once the running belt has been adjusted closer to the center of the treadmill
use about 1/4 of a turn until the belt has been stabilized.

! CAUTION: While centering the belt choose one bolt to adjust. Do not adjust both

bolts.

After the belt has been centered, check the belt tension. Make sure the running belt tension

is
tight enough so that the belt does not slip or hesitate when stepped on. Walkonthe treadmill
at 3.5-4 mph (5.6-6.4

kph)

and every 4th to 5th step throw your weight into your step to

feel

if

the beltisslipping. If the belt does slip,

use

a wrench to equally tighten both

Check

belt

condition.

A.

Run

your hand under the beltonthe top of the deck surface. If you notice any

excessive ridges, furrowing or cracks

in

the deck or if the deck feels very rough,
the surface may have worn down to a point where it could start to cause excessive
wear to the undersurfaceofthe running belt. For running belt replacement

information see Running Belt

in

the Removal and Replacement chapter.

4.

Replace

the

side

rails and

plastic

end caps.

A. Slide the two side rails back

on

being sure to catch the rail guides.

B. Attach the plastic end caps with the Phillips screwdriver.

NOTE: For running belt replacement information see Running Belt in the Removal

and

Replacement chapter.

! CAUTION:

Do

not

use a

belts

are

specific

for

each

and

may

be

Rotating

the

Deck-You

may rotate the deck but do not flip the deck. The wax surface

is only on the top side of the deck.

Do

not rotate the belt. The belt is directional. See

Running Belt and Running Deck

in

the Removal and Replacement chapter.

Belt

and

Deck

Surfaces -

To

minimize the effect of friction between the deck and the

running belt, Cybex recommends cleaning the underside

of

the running belt and the top
on the running deck surface by wiping them with a clean, dry towel. This simple
procedure should be done approximately four times a year to prevent premature wear of
the deck, running belt and the drive motor system.
