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 0.25 inches of each side rail. Adiust the bek if necessary.
• Check the optional side hand rails. Fasten them securely.
, Remove potential hazards from the treadmill area.
Cleaning
Clean the treadmill on a regular basis he_ps to improve operation and increase component _ifespan.
Da i ly
• 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. DW all 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. Turn the 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#_g bek loose, place two marks 35 inches
(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_q6 inches 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 35o5/16 inches,
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
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 bout slip on the,front rotle_, increase
the tension of each adjo£ment bolt by 1/2 turn.
Then rete£. If you fee_the holt sli_ agai_s,check the
tensioner adiustmenL

Adjusting Belt Tracking
Adiust the be_t tracking 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

Lubrication
There are nine componentsthat need periodic lubrication: the drive chain, the

the pedal arm bushings,the leveling arm bushings,the spring pulley shafts,
the pedal shafts and the leveling arm pins. Thesepars are shown in Figure 11,
page 74. Removethe bottom coverto get to the components.If you have a
