Nautilus T9 Series Treadmills

Daily

• Inspect the power cord and wal[king belt for wear,
, Check the position of the walking belt. Verify it does not rub against the frame, Evenly space the be,It on the deck

within 0.25inches of each side rail. Adiust the bek if necessary.

• Check the optional side hand rails. Fastenthem securely.
, Remove potential hazards from the treadmill area.

Cleaning

Clean the treadmill on a regular basis he_psto improve operation and increase component _ifespan.

Da ily

• Keep the treadmi_ arid controller free of du_ and debris. Use a damp sponge to wipe the exteriors and walking bek.
Do not soak sudaces. DWall surfaces thoroughly.

Dry mop the deck under the belt onl[y.Do not add any lubricants--adding lubricants can ruin the proprietary friction-
control sudace. Do not use detergents or cleaning agents on any par of the deck. Do not let liquid enter the treadmill

or controller, if it does, have a NautiBs ÷ approved technician inspect and test the equipment for safety by a before
using it again.

WeeMy

• Elevate the treadmill to maximom incline and vacuum the floor under it. This prevents excess dust and di_ from
interfering with operation.

If using the magnetic key, check it for rust: If you see rust, replace the magneL Rust en the magnetic key causes
power-up problems.

Treadmill Integer

_ angerous voltages are present under the treadmill hood:. Use caution when performing service to the e]ectrica_

components under the hood.

Depending upon the treadmill environment, dust and or lint can accumu_ate under the hood. Clean the interior of the

treadmill by doing:

1. Turnthe treadmill circuit breaker off. Unplug the treadmill power cord.

2. Remove the two screws on the treadmill hood.

S.Lift off the hood,

4. Cban inside the unit.

5, Reinstal_the hood and the _o screws,

6. Plug in the trea@nill power cord end switch on the trea@ni_[circuit breaker.

Do not ove_ighten the walking heft. Be not torque adj_stment screws beyond _ in@s {9 N-M}. 0ve_ightening
reduces the beff life and may damage the rolbr bearings.

Adjusting Belt Tension

Adiust the heft tension whenever the heft s_ipsor moves
unsteadily during operatiom

1.Loosen the _o adiustment bolts (See Rgore 1}.

2.With the w'a[k#_gbek loose, place two marks 35inches

(89 cm} apa_ on each side of the heft near the edge,
The belt must be loose enough for you to move it from
side-to-side on the front or rear ro_ler(See Figure 2}.

3. Turn the adiusting bolts cbckwise in equa_amounts
until the marks are be_een S5o_q6inches and 35°d16

inches a£art, Proper tension for the walking heft is
between .5%-.6%. This equaB six fu]_turns of each

adiustment heft from the point where the belt begins to

stretch.

NOTICE: #o not exceed 35o5/16inches,

4.Test the belt by running on the belt at about 4 mph.
Hold the handrail lightly arid resist the belt movement

with your feel

Figere 1

Bo not ose a_lyour weight to resist the beff movement.

Too much resistance applied too bng (more than two

seconds) may shut down the system. {Various error
messages show on the display if this occurs, Cycle

power to resume normal operation.)

5. ff you feel the boutslip on the,front rotle_, increase

the tension of each adjo£ment bolt by 1/2turn.
Then rete£. If you fee_the holt sli_ agai_s,check the

tensioner adiustmenL

Figure 2

Oonotcutthebe_t.Doingso can cause the rear rol_er to fall and snap the alignment pins on the end c:ap.

Adjusting Belt Tracking

Adiust the be_ttracking whenever the belt moves to one side
or the other. Stay off the bek when adiu_ments.

1.Sta_ the treadmill at minimum speed and grade.

2,Increase speed to 6 m#h. Make the following

2=1 If the belt moves to the right: turn the right

adia_ment bok 1/4-tam c_ockwise.

2=2 If the belt moves to the left: turn the _efl

adiu_ment bok 1/4°turn clockwise.

3. Run the treadmill for 5 mim_tes after making the initia_
adiustmenL Observe how the belt tracks. # the belt

Chat:king the Battery Charge

Using your multimeter, touch the red lead to the positive termina_ of the battew and the black lead to the negative

terminal.

2. If the voltage level is less than 6.1 VDC, charge the battery.

Rechargi N the Batt÷W Back-Up

The CommerciaF Series U916 and R916 bikes are both self-powered (cordless)with a rechargeable batteW back-up.
Typically, the bike can be operated without Nugging in the battery charger. If, however,, the console flickers during

o#eration or the console disNay does not _igN u# while using the machine, then use the battew charger to recharge the

batteW back-up.

The bakery charger is suf_Nied with the unit and plugs into a standard 115 volt, 15 amp outlet, or a 220 volt, 15 amp outlet.
{A[[ maior voltage Nugs are available.} The Nug-in for the battery charger is located

in the front of the machine at the base.

NOTE: If in.ailing the optiona_ LCD Monito5 refer to the NV915 installation manual at

this time.

Plug the wail pack battew charger into the connector and charge the bakery for
approximatNy 24 hours and then recheck it. it is okay to use the machine while the

battery charger is connected.

When the bike is net connected to an external power source, the console will power
on as the user starts to pedal machine, and wil_ stay lit for up to 60 seconds in pause

mode. The consNe wil_ power off a_er 60 seconds of stopping exercise.

If the bike is connected to an externa_ power source, the console will power on automatically and stay on until power is

disconnected.
