Regular Maintenance Activities
Preventative maintenance activities must be performed to maintain normal operation of this equipment.
Keeping a log sheet of all maintenance actions will assist you in staying current with all preventative
maintenance activities.
WARNING: Equipment found to have worn or damaged components must be removed
from service until repair(s) is made. Failure to do so could result in injury.
Daily
1. Clean upholstery.
Weekly
1. Inspect all nuts and bolts for looseness. Tighten as required.
2. Check for worn handles, and worn warning labeling. Replace all worn parts immediately.
2 - Exercise
Intended Use
The intended use of this equipment is to aid or improve general physical fitness and exercise. For Comercial use.
Before you workout
Prior to starting a training program, get a complete physical exam to make sure your physician agrees that you are
ready. Always warm-up your muscles before a workout.A 5 - 10 minute cardio warm-up followed by slow stretching
(no bouncing) is recommended. Continue with a lighter set (50% of normal) of intended exercises. Start your program
conservatively. Choose weights you can easily lift in the first weeks. Always perform the full range of motion unless
you have an injury, then consult a professional trainer. Know the terms. A “repetition” (rep) is defined as one complete
movement through an exercise, returning to the start position. A “set” is a continuous series of reps usually between
6-15.
During your workout
The number of reps you perform in a set depends on your goal. To build muscle and strength, do fewer reps
(6 - 8) with heavier weight. To build endurance, do more reps (12-15) with lighter weight. Never “cheat” by shortening
the range of motion, bouncing the weight, or shifting your posture. This may allow you to lift more weight, but it is
dangerous and less effective. Catch your breath between sets, then continue. When “circuit training” move briskly
to the next exercise; when doing multiple sets on one exercise, rest 45 - 90 seconds before the next set. Work up to
three sets per exercise. When you can perform the desired reps and sets for any exercise, increase the weight by a
half or full plate.
Designing your workout
Circuit training is a good way to start. This involves doing one set per exercise, then moving to the next exercise,
pausing only briefly between them (to keep your heart and breath rate up) until completing a balanced “circuit” of 8 -
10 exercises for your entire body. Then repeat the circuit.After several weeks, you can move into multiple sets (3 in
a row) per exercise if you choose. For both of these, exercise the complete body every other day, up to three times a
week. NOTE: A full day’s rest, plus proper nutrition and hydration are required for optimum muscle-building or toning.
Alternatively, work out half your body one day (e.g., the upper body) and the other half the following day (e.g. the
lower body). At the end of your workout, cool down in a similar way to your warm-up.

Damaged Parts
Materials damaged in shipment should not be returned for credit. Shipping damages are the responsibility of the carrier
(UPS, Federal Express, trucking companies, etc.)
Apparent Damage - Upon receipt of your shipment, check all items carefully. Any damage seen with a visual check must
be noted on the freight bill and signed by the carrier’s agent. Failure to do so will result in the carriers refusal to honor your
damage claim. The carrier will provide you with the required forms for filing such claims.
Concealed Damage - Damage not seen with a visual check upon receipt of a shipment but notices later must be reported
to the carrier as soon as possible. Upon discovery of the damage, a written or phone request to the carrier asking them to
perform an inspection of the materials must be made within ten days of the delivery date. Keep all shipping containers and
packing materials as they will be needed in the inspection process. The carrier will provide you with an inspection report
and the necessary forms for filing a concealed damage claim. Concealed damage claim is the carrier’s responsibility.

2. With a flat blade screwdriver, carefully pry off foot glide.
3. Carefully place rubber feet (supplied with machine) on each foot of the frame.
