HOW TO ... REMOVE AND REPLACE THE CHOKE
Tools Required: Phillips screwdriver, socket and wrench set
WARNING: FAILURE TO OBSERVE SAFE PROCEDURES WHEN SERVICING THIS UNIT
COULD RESULT IN INJURY FROM ELECTRICAL SHOCK.
Step 1
Turn the power OFF at the ON/OFF switch and then unplug the unit from the electrical outlet.
Step 2
Remove the MOTOR COVER (See How To...”).
Step 3
With the power to the machine OFF , hold the handrails and walk on the treadmill until the STRIDING BELT
completes at least one revolution around the rollers (this will aid in releasing any electrical charge which may be
held in the CAPACITOR). Remove the CAPACITOR CAP and
use a DC Voltmeter to check and insure that the
CAPACITOR does not hold a charge prior to proceeding to Step 4.
Step 4
Using a socket and wrench, loosen and remove the four NUTS securing the CHOKE to the STUDS on the MOTOR
PAN.
Step 5
Lift out the CHOKE and slide off each of the two CONNECTORS from the side of the faulty CHOKE and connect
them to the new CHOKE in the same locations.
Step 6
Place the new CHOKE into position and reverse Steps 1 through 5 to return all parts to their proper locations.
