SYMPTOM: The walking belt slows when walked on

a.  

Use only a surge suppressor that meets all of the 
specifications described on page 15.

b.  

If the walking belt is overtightened, incline trainer 
performance may decrease and the walking belt 
may become damaged. First, adjust the incline to 
40%. Then, remove the key and 

UNPLUG THE 

POWER CORD.

 Using the hex key, turn both idler 

roller screws (A) 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 
3 to 4 in. (8 to 10 cm) off the walking platform. Be 
careful to keep the walking belt centered. Then, 
plug in the power cord, insert the key, and walk on 
the incline trainer for a few minutes. Repeat until 
the walking belt is properly tightened.

c.  

The incline trainer features a walking belt coated 
with high-performance lubricant. 

IMPORTANT: 

Never apply silicone spray or other substances 
to the walking belt or the walking platform 
unless instructed to do so by an authorized 
service representative. Such substances may 
deteriorate the walking belt and cause exces-
sive wear. 

If you suspect that the walking belt 

needs more lubricant, see the front cover of this 
manual.

d.  

If the walking belt still slows when walked on, see 
the front cover of this manual.

SYMPTOM: The walking belt is off-center or slips 
when walked on

a. 

 If the walking belt is off-center,

 first adjust the 

incline to 40%. Next, remove the key and

THE POWER CORD.

If the walking belt has 

shifted to the left,

 use the hex key to turn the 

left idler roller screw clockwise 1/2 of a turn; 

if the 

walking belt has shifted to the right,

 turn the left 

idler roller screw counterclockwise 1/2 of a turn. Be 
careful not to overtighten the walking belt.

Then, 

plug in the power cord, insert the key, and walk on 
the incline trainer for a few minutes. Repeat until 
the walking belt is centered. 

b. 

 If the walking belt slips when walked on,

 first 

adjust the incline to 40 percent. Next, remove the 
key and

of a turn. When the walking belt is correctly tight-
ened, you should be able to lift each edge of the 
walking belt 3 to 4 in. (8 to 10 cm) off the walking 
platform. Be careful to keep the walking belt cen-
tered. Then, plug in the power cord, insert the key, 
and walk on the incline trainer for a few minutes.
