Attaching the Magnet and Reed
Switch
For the electronic console displays to operate properly, a
magnet and reed switch need to be precisely installed. The
magnet is mounted to the flywheel and the reed switch is
placed on the side rail. Mounting pads indicate where you
need to mount the hardware. Be sure to follow the previous
instructions
the magnet or reed switch.
Installing the Mounting Pads
before attaching
page 14
To install the magnet and reed switch, take the following
steps:
CAUTION: To ensure the integrity of the reed switch,
lower the handrails before mounting the reed switch.
Allowing excess wire near the flywheel eliminates the
possibility that the reed switch will be pulled out of
position. If you are not sure how to lower the handrails,
refer to your Owner’s Manual.
Diagram 12
1. Remove the paper from the adhesive strip on the
flywheel’s foam mounting pad.
2. Wipe the back of the magnet with a dry clean, soft
cloth. Position it over the foam mounting pad on the
flywheel and press it onto the adhesive strip. Check
that it is securely mounted. See Diagram 12.
3. Wipe the base of the reed switch (the “base” is the
side opposite the ++) with a clean cloth.
CAUTION: Check the alignment of the +’s on the
reed switch with the magnet before adhering the
reed switch onto the side rail mount. For the
electronics to operate properly, the magnet can only
pass over one of the +’s on the reed switch.
4. To check the alignment between the magnet and reed
switch, move the flywheel slightly so that you can
place the base of the reed switch onto the foam
mounting pad. You should be able to see and read the
positive (+) signs. Position the reed switch between
the roller guard and deck so that the magnet passes
over one of the “+” markings on the reed switch.
Important: If the magnet passes over both “++” on the
reed switch, a false count or an erratic display can
appear on the electronic console.
page 15
Diagram 13
5. Remove the paper to expose the adhesive strip that is
on the foam mounting pad. Press the reed switch onto
the pad. Be sure that the reed switch is positioned so
that the wires are easily routed up the handrail. See
Diagram 13.
6. Rotate the flywheel by hand to make sure that the
magnet and reed switch are secure and are not
rubbing on each other or on the treadmill. Check that
the reed switch wire is clear of the flywheel. If the
magnet and flywheel are not correctly aligned you may
get incorrect readings on the display. Reposition the
magnet and reed switch if necessary.
7. Secure the handrails into an upright position.
page 16
8. Check the wires to be sure no excessive amount of
wire hangs down where it could cause entrapment or
injury to someone. Realign the wire and move the
C clips along the handrail if necessary.
9. DO NOT OPERATE the treadmill for a 24-hour period.
The adhesive on the mounting pads requires this
amount of time to bond properly.
