SAFETY & USAGE
Taking Care of your SPX Reformer

Carriage Stopper
The carriage stopper position determines how close the carriage
slides in toward the wooden standing platform and dictates the
range of motion required of the body's joints. The hole closest
to the wooden standing platform is referred to as position #1;
the next hole is position #2, etc.
Adjusting the Carriage Stopper
Do not sit on carriage while adjusting.
w
Remove all springs from gearbar.
w
Insert carriage stopper in one of six positions.
w
Be sure carriage stopper is completely
w
inserted in the hole and is not loose.
The carriage stopper position should usually be selected so that
when lying supine (on your back), with heels on the footbar,
there is a 90° angle of flexion at the hip joint when the carriage is
against the carriage stopper. If injury, disease or other limitations
restrict flexion at the hips or knees, adjust the carriage stopper
by placing it farther out. Adjustments can also be made for the
exercise being performed.
NOTE: The carriage stopper must be inserted in one of the
six positions AT ALL TIMES. Using the Reformer without the
carriage stopper may cause damage to the gearbar assembly,
rollers or spring holder.

Gearbar
The gearbar position determines the amount of initial tension
on the springs. The slot closest to the wooden standing platform
is position #1; the next is position #2; the next is position #3.
Lower position numbers provide higher spring tension.
Adjusting the Gearbar
Do not sit on carriage while adjusting.
w
Remove all springs from gearbar.
w
Place gearbar in desired position.
w
Ensure gearbar slides fully into slots.
w
Ensure concave indentations face toward footbar.
w
Position gearbar relative to the carriage to create initial tension
on the springs, i.e. the gearbar should not be in position #3 if the
carriage stopper is in position #1 or #2 as there will not be any
spring tension.
Springs
Replace all Springs every 24 months.
The number of springs attached to the gearbar determines the
total amount of resistance. SPX Reformers are equipped with
®
four 100%-tension springs, and one 50% spring.
Adjusting Springs
Take care when attaching and detaching springs from gearbar..
w
For safety, place one hand on gearbar.
w
Firmly grasp spring (not the ball on the spring) and
w
stretch it to hook to or unhook from gearbar.
Ensure ball end rests securely in concave indentations
w
of gearbar.
