ProForm 1200 Interactive Trainer Treadmill, User Manual

With the help of a second person, carefully raise the
Upright Base (97) as shown. Carefully pivot the Hood
(123) off.

Locate the Reed Switch (22) and the Magnet (19) on
the left side of the Pulley (18). Turn the Pulley until the
Magnet is aligned with the Reed Switch. 

Make sure

that the gap between the Magnet and the Reed
Switch is about 1/8”.

If necessary, loosen the Screw

(23) and move the Reed Switch slightly. Retighten the
Screw. Reattach the Hood, and run the treadmill for a
few minutes to check for a correct speed reading.

PROBLEM: The walking belt slows when walked on

SOLUTION:

a. Use only a single-outlet surge suppressor that meets all of the specifications described on page 8.

b. If the walking belt is overtightened, treadmill perfor-

mance may decrease and the walking belt may be-
come damaged. Remove the key and 

UNPLUG THE

POWER CORD

. Using the allen wrench, turn both

rear roller adjustment bolts counterclockwise, 1/4 of a
turn. When the walking belt is properly tightened, you
should be able to lift each side of the walking belt 2 to
3 inches off the walking platform. Be careful to keep
the walking belt centered. Plug in the power cord, in-
sert the key, and run the treadmill for a few minutes.
Repeat until the walking belt is properly tightened.

c. If the walking belt still slows when walked on, please call our Customer Service Department.
