Remove the three #8 x 3/4" Screws (1) and care-
fully pivot the Motor Hood (62) off.
Locate the Reed Switch (73) and the Magnet (47)
on the left side of the Pulley (48). 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 in. (3 mm). If nec-
essary, loosen the #8 x 3/4" Truss Head Screw
(18), move the Reed Switch slightly, and then
retighten the Screw. Reattach the Motor Hood (not
shown) with the #8 x 3/4" Screws (not shown).
Reattach the #8 x 2" Screws (not shown) if neces-
sary. Run the treadmill for a few minutes to check
for a correct speed reading.
PROBLEM: The incline of the treadmill does not change correctly
SOLUTION: a. With the key in the console, press one of the Incline buttons. While the incline is changing, re-
move the key. After a few seconds, re-insert the key. The treadmill will automatically rise to the
maximum incline level and then return to the minimum level. This will recalibrate the incline system.
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 14.
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 hex key, turn both
idler roller bolts counterclockwise, 1/4 of a turn.
When the walking belt is properly tightened, you
should be able to lift each edge of the walking belt
2 to 3 in. (5 to 7 cm) off the walking platform. Be
careful to keep the walking belt centered. Then,
plug in the power cord, insert the key, and run the
treadmill for a few minutes. Repeat until the walk-
ing belt is properly tightened.
c. If the walking belt still slows when walked on, see the front cover of this manual.

Questions and answers
I purchased model PFTL59510.0 and I **** in search of a Proform treadmill similar to this one.
The ProForm treadmills similar to model PFTL59510.0 include the ProForm 415 Crosswalk Treadmill (23723.3 / 237233) and the ProForm XP 680 Crosstrainer Treadmill (24646.0 / 246460).

pro-form 400e starts but won't stay running.
The ProForm PERFORMANCE 400 treadmill may start but not stay running due to several possible reasons:
1. Safety Key Issue – If the safety key is not properly inserted or gets disconnected, the treadmill will stop.
2. Motor or Belt Problem – A faulty motor, loose drive belt, or worn-out walking belt can cause the treadmill to stop.
3. Overheating or Overload – If the treadmill overheats or detects excessive load, it may shut off as a safety measure.
4. Power Supply Issue – Inconsistent power supply, a loose power cord, or a tripped circuit breaker can interrupt operation.
5. Console or Sensor Malfunction – If the console is not detecting movement correctly, it may stop the treadmill.
To diagnose the issue, check the safety key, ensure the belt is properly aligned, confirm the power source is stable, and inspect the motor for overheating.

My motor seems to be very loud. What could cause it to run loud?
The document does not provide specific reasons for the motor of a ProForm PERFORMANCE 400 running loudly. However, loud motor noise in treadmills is commonly caused by worn motor bearings, a loose or damaged drive belt, or buildup of dust and debris inside the motor area. Regular maintenance and inspection may help identify and resolve such issues.
