kBox4 manual v 8.7
Personal injuries may occur if these precautions are not observed
Please read and understand user manual and warning labels prior to use.
Inspect the machine including the drive belt before use.
 Damaged or worn parts and
warning labels must be replaced. See user manual for how to change and cut the drive
belt. Do not modify the machine or repair it with non OEM parts.
Never step off the kBox while the flywheels are moving. Make sure flywheels come to a
complete stop before you end the exercise, disconnect or step off.
The kBox can deliver a supramaximal* workload. Do not exercise at an intensity you
cannot manage.
Workout at a submaximal** intensity until you are familiar with the equipment.
Don’t let the pulley block hit the kBox, absorb the eccentric load BEFORE it hits the kBox.
If you feel dizzy or experience pain, stop exercising immediately. 
Exxentric takes no responsibility for any injuries that may occur.
Keep away from moving and rotating parts.
This machine and accessories are intended for strength training only. Do not use in any
other way.
Exercising at maximum intensity may cause temporary staggering and uncontrolled
body movements due to fatigue. Exercise caution to prevent falling.
The machine might get slippery when wet. Use clean shoes and dry machine with a
cloth if it is wet. Shoes with spikes, dirt, stones can damage the rubber surface of the
kBox.
Never stop an exercise in top position.
Both feet have to be placed on the kBox during exercise if it’s not fixed to the ground.
Always place the kBox on a leveled surface.
If you have balancing problems, be sure to have support by a spotter or fixed object like
a wall.
Always make sure children and pets cannot access the machine when in use.
*) Supramaximal means higher than maximal. This means higher loads than your
muscle can produce themselves in a shortening (concentric) action.
**) submaximal means below maximal. In this case, we would recommend below 75% of
max intensity.
