MAINTENANCE AND TROUBLE-SHOOTING
Inspect and tighten all parts of the PROFORM
¨
775s
regularly. The 775s can be cleaned with a soft, damp
cloth. To prevent damage to the console, keep liquids
away and keep the console out of direct sunlight.
BATTERY REPLACEMENT
If the console does not function properly, the batteries
should be replaced. To replace the batteries, refer to
assembly step 8 on page 6.
HOW TO ADJUST THE REED SWITCH
If the console does not display correct feedback, the
reed switch should be adjusted. In order to adjust the
reed switch, the Left Side Shield (6) must be
removed. First, using an adjustable wrench, turn the
Left Pedal (45) clockwise to remove the Pedal from
the left arm of the Crank (29).
Remove all Screws (21, 22) from the bottom of the
Left Side Shield (6). Grasp both Side Shields at the
top and gently pull them apart. Make sure that the
arm of the Crank (29) is in the position shown in the
drawing above. Hold the Left Side Shield at the rear
and pull it gently away from the frame. Work the Left
Side Shield forward off the arm of the Crank and
remove it.
Next, locate the
Reed Switch (13).
Loosen, but do not
remove, the M4 x
16mm Screw (22).
Slide the Reed
Switch slightly
toward or away from
the Magnet (57) on
the pulley. Retighten
the Screw. Turn the Crank (29) for a moment. Repeat
until the console displays correct feedback. When the
Reed Switch is correctly adjusted, reattach the left
side shield.
HOW TO ADJUST THE DRIVE BELT
If the you can feel the pedals slip when you are exer-
cising, especially when the resistance knob is turned
to the maximum setting, the Drive Belt (19) may need
to be adjusted. To adjust the Drive Belt, both side
shields must be removed. Refer to the instructions at
the left to remove the left side shield. Remove the
right side shield in the same manner.
Loosen the M8
Flanged Hex Nut
(36) on each side of
the Flywheel (42).
Tighten the M6 Nut
(39) on each M6
Eyebolt (37) until the
Drive Belt (19) is
tight. Be sure that
you tighten each
M6 Nut an equal
amount. Once the
Drive Belt is tight,
tighten the M8 Flanged Hex Nuts (36). Reattach the
side shields.
CRANK ADJUSTMENT
If the arms of the
Crank (29) become
loose, they should
be tightened in order
to prevent excessive
wear. Loosen the
Crank Nut (35) on
the left arm of the
Crank. Place the
end of a standard
screwdriver in one
of the slots in the
Slotted Bearing Nut
(33). Lightly tap the screwdriver with a hammer to turn
the Slotted Bearing Nut counterclockwise until the
arms are no longer loose. Do not overtighten the
Slotted Bearing Nut. When the Slotted Bearing Nut
is properly tightened, tighten the Crank Nut.
STORAGE
When storing the exercise bike, remove the batteries
from the console. Keep the exercise bike in a clean,
dry location, away from moisture and dust.
