Calculating weight:
Each handles weigh 5 lbs empty and 10 lbs with the two locking screws. To determine the weight of your
dumbbell, simply count the weight plates on one end of the dumbbell and multiply by the plate weights. Dou-
ble this number and add 10 lbs for the handles and locking screws.
Example:
A Quick
-
Lock Dumbbell with four 5 lb plates and one 2 ½ lb plate on each end = 22 ½ lbs of
plates on one end. 22 ½ lbs x 2 = 45 lbs + 10 lbs = 55 lbs total dumbbell weight. See illustration.
Safety:
1.
Do not attempt to use more plates than the locking screws are designed to hold. The maximum number of
plates with the standard included locking screws is six 5 lb plates plus one 2.5 lb plate on each end (75 lbs
total dumbbell weight).
2.
Although the locking system is simple and safe, it is good practice to check the tightness of the locking
screws between sets. The screws may actually lock any where from the 2 o’clock position to 10 o’clock. This
is normal. They will not release the weights unless the arrows are lined up with the notches in the 12 o’clock
position. It is recommended to re
-
check the locking screw tightness after each use between sets. Do not
over
-
tighten the screws or use tools. It is not necessary and only makes it more difficult to open them later.
3.
The Quick
-
Lock dumbbells are strong and durable for normal dumbbell exercise use. The dumbbells can
be dropped without damage if done carefully. Do not intentionally throw them or drop from excessive heights.
Dropping the dumbbells at an angle or on the corners may result in some bending. If dropping is necessary, it
is recommended to drop on the side horizontally or on the ends vertically.
4.
Keep children away from this equipment. Weight plates or dumbbells can cause injury. Do not let anyone
climb on the dumbbell stand.
5.
It is important that the optional dumbbell stand be placed on a level firm surface and the table top is level.
You may adjust the table level with the rubber feet on the bottom of the rack if necessary. This helps to in-
sure the weight plates will not fall over during weight changes. They are designed with tapered edges so they
will always fall into the handles. Use care if the dumbbells are set down on other surfaces.
6.
Weight lifting can be dangerous. Use caution and control when lifting and be sure to consult a physician
to be sure it is safe to engage in free weight training prior to use.
