1. After you remove the dumbbell from its protective packaging, inspect the products and packaging material for damage.
2. Pushdown slightly on the handle assembly to make sure it is fully seated in the base. Rotate the adjustment knob several full rotations to make sure it turns freely in both
directions. Make sure there is a click at each weight increment of the adjustment knob. This click will help you align the knob correctly to make a weight selection.

Note:
The weight increments range from 4 to 45 lbs (1.8 kg to 20.4 kg) on the adjustment knobs.
To make a weight selection, turn the adjustment knobs until that number is aligned with the line (L1) on the top surfaces of the handle (Fig. 1). For example, to set
the weight to 20 lbs (9 kg), align the number 20 with the line on the handle.
3. After you make sure that the adjustment knob turns correctly, turn the knob so that the number 4 is aligned with the line on the handle (Fig. 1).
4. Withthe adjustment knobs set to 4, pull the handle straight up from the dumbbell. This will remove only the handle from the base, and let all of the weight plates stay in
the base (Fig. 2). The handle without plates gives the initial weight of 4 lbs (1.8 kg).
NOTICE: When you remove the dumbbell from the base or return it to the base, use a vertical motion, perpendicular to the base. Do not tilt the
dumbbell or move it laterally (parallel to the base) until it is fully clear of the unselected weight plates.
Note:Note:
Note:
The dumbbell handle and weight plates are symmetrical. When you put the dumbbell back into the base, the ends of the handle can
point in either direction.

Fully understand the function of this mechanism and do tests of the mechanism regularly to make sure it operates correctly.
The locking mechanism supplies two key functions:
1. The mechanism will only let the adjustment knobs turn when the dumbbell handle fully engages the dumbbell base. The mechanism prevents deselecting (dropping)
weight plates from the dumbbell when it is NOT in the dumbbell base.
2. The mechanism will lock the dumbbell handle to the base if the adjustment knobs do not fully engage the weight plate selection. The mechanism prevents partial
selection of the weight plates in which the locking pin is not fully engaged and does not fully hold the plates.
