4100PT Placement
Right hand vs. Left hand
References to the right hand (RH) and left hand (LH) side of
the machine are based on the final user position facing the
console.
Placement
Your 4100PT StairClimber may be placed on either hard
flooring or low carpet.
We recommend placing a rubber mat or other protective
material under your stepper to prevent grease and oil from
damaging your flooring.

- 8 -
4100PT Placement
Moving
Your 4100 StairClimber is easily movable. Verify the two
transport wheels are secure with cotter pins. Then grasp
the siderails just below the console, with a foot resting
against the front frame leg, tilt the machine towards you so
it is balancing on two transport wheels. Push or pull
machine to the desired location and gently set the rear of
the machine back down to the floor.
For added convenience, the width of your 4100 is only
29.5”, narrow enough to fit through most residential
internal doorways.
CAUTION: Your 4100 StairClimber weighs approximately130
pounds, Always use care when moving equipment and ask for
additional assistance if necessary.
Leveling
The four hexagonal leg caps at the end of the front and
rear legs are used for leveling. The caps are asymmetric,
numbered 1-4 with 1 being the thinnest wall and 4 being the
thickest. To adjust, slide the caps off the ends of the legs
and rotate to the desired thickness and slide back over the
leg. The caps fit snuggly to the frame and some force may
need to be applied.

Exercise guidelines
For Healthy Aerobic Activity
As published by the American College of Sports Medicine
Fitness Goals: An Important step in developing fitness program is setting
your individual fitness goals. Some common exercise goals include:
•Weight loss
•Improve body tone and muscular strength
•Increase energy
•Increase cardiovascular endurance
•Reduce stress
The more specific and measurable your goals, the easier it will be to track
your progress. If you have very long-term goals, break them down into
smaller short-term goals to make them easier to achieve. Success breads
success! One of our goals at StairMaster is to help you succeed in
achieving your fitness goals!
Frequency: Exercise 3 to 5 days each week.
Warm up: 5 to 10 minutes before aerobic activity. When exercising, your
body needs more oxygen to fuel your muscles. This increase demand for
oxygen is what causes your heart rate, breathing rate and blood flow to
increase. Your warm-up activity should be progressive and involve all the
muscles you plan to use during your workout. A warm up should involve a
very gradual increase in intensity and range of motion. Your overall
fitness and type of workout will help determine the length of your warm-up,
5-10 minutes is normally recommended. Your warm-up should leave you with
a slightly increased heart and breathing rate but should not leave you
feeling fatigued.
Duration: Maintain your exercise intensity for 30-45 minutes. If weight
loss is a major goal, recommendations are to maintain at least 30 minutes 5
days a week.
Cool Down: Gradually decrease the intensity of your workout, The
opposite of the warm up is what is accomplished during the cool down. Your
muscles have been consuming large quantities of oxygen and a gradual
decrease in your intensity if best for your body. Again, the type of workout
and overall fitness will determine the length of your cool down but 5-10
minutes is recommended. The goal of the cool down is to gradually
decrease intensity and range of motion the same muscles used during your
workout. This will allow your heart and breathing rate to return to near
normal levels gradually. then stretch to cool down during the last 5 to
10 minutes.
