http://www.P65Warnings.ca.gov
WARNING: Never allow children to use or play near this equipment. Anyone under the age of 18 must always

• It is the purchaser’s sole responsibility to properly instruct its end users and supervising personnel as to the proper
operating procedures of all equipment.
• This equipment is not intended for use by children. Keep children under the age of 14 away from the machine.
• Do not allow users to wear loose fitting clothing or jewelry while using equipment. It is also recommended to have
users secure long hair back and up to avoid contact with moving parts.
Inspection
• DO NOT attempt to use or repair any accessory approved for use with the equipment which appears to be
damaged or worn.
• DO NOT use or permit use of any equipment that is damaged and/or has worn or broken parts. For all Life Fitness
Family of Brands equipment, use only replacement parts supplied by Life Fitness Family of Brands.
• Maintain labels and name plates - Do not remove labels for any reason. They contain important information. If
unreadable or missing, contact Life Fitness Family of Brands customer service for a replacement.
• Equipment Maintenance - Preventative maintenance is the key to smooth operating equipment as well as to keep
your liability to a minimum. Equipment needs to be inspected at regular intervals.
• Before use, examine all accessories approved for use with the Life Fitness Family of Brands equipment for damage
or wear.
• Inspect the dumbbells prior to each use. Do not use a dumbbell with worn, damaged, or loose parts, fasteners or
hardware.
Safety Features and Proper Usage
• Do not use any equipment in any way other than as designed or intended by the manufacturer. It is imperative that
Life Fitness Family of Brands equipment is used properly to avoid injury.
• Injuries may result if exercising improperly or excessively. It is recommended that all individuals consult a physician
prior to commencing an exercise program. If at any time during exercise you feel faint, dizzy or experience pain,
STOP EXERCISING and consult your physician.
• Never allow the dumbbells to drop freely to the ground. Damage to the products, floor surfaces and potential

• Never allow dumbbells to forcefully strike against each other during use. Damage to the product and potential

• Never attempt to disassemble a Life Fitness Family of Brands handle for any reason. Life Fitness Family of Brands
products are not designed to be user serviced. Contact Life Fitness Family of Brands customer service directly for
service.
Page 4 of 13

• Before beginning your workout, make certain that your surroundings are free from potential interference.
• Pro 100 dumbbells are very heavy; if you are not using an optional Hammer Strength Stand, we suggest you place
the dumbbell set directly on the floor for best support.
• Removing or replacing the handle and weights from the nest must be done in a straight motion (Image 1). Turning
the handle sideways while lifting may jam the assembly (Image 2).
DANGER: Do not use if weights are jammed. Using while jammed may result in falling weights and/or injury
to you or others around the weights.
Image 1 Image 2
• The weight selector pins contain magnetic blocks. Make sure the magnetic blocks contact the round side rails. The
selector pin should be horizontal and fully engaged securely to the side rail of desired weight (Image 3). Be careful
not to cross pin (Image 4).
WARNING: Always check the selector pin to make sure it is fully inserted and completely engaged before
lifting the dumbbell to avoid injury (Image 3). If the selector pin disengages from the side rails, stop use
immediately. Place dumbbell on nearest flat surface and fully engage selector pin magnetic blocks securely
to the side rails. Failure to maintain full and correct contact between magnetic blocks in selector pin and
side rails may result in weights falling and/or injury. Do not use the dumbbell without the tether cord being
in good working condition and attached to the top side rail and selector pin. Weight selector pin may fall out
of dumbbell if used without tether cord and may result in falling weights and/or injury.
Image 3 Image 4
• Your dumbbell features a tether cord which attaches the selector pin to the weight plates on the #1 or top most
weight plate side rail. The tether cord will prevent the selector pin from being misplaced. The tether cord also
serves as a safety retainer for the weight selector pin in the event the magnetic blocks ever lose contact with the
side rails.
• Lift from center grip of handle only (Image 5).
Page 5 of 13

Image 5
• Do not strike dumbbells together during any exercise. Any contact between a dumbbell and another piece of
equipment or a body part could result in a selector pin dislodging.
DANGER: Lift from center handle only. Lifting from any other part of the dumbbell may result in falling
weights and/or injury. Striking dumbbells together could dislodge pins and result in falling weights or injury.
• Lift the handle and weights above the nest and visually inspect for correct placement of the weight selection pin
(Image 5).
• The open/close arrows on the top decal of each handle indicates the position of the Auto Lock and whether the
lock that holds the Chrome Adder Weights is engaged or disengaged. (Image 6 & 7)
Image 6 Image 7
• Because the Chrome Weights slide in/out easily, be sure to place your hand in front of the handle when unloading
them.
• Optional stands for the dumbbells contain storage ports for the Chrome Weights when not inserted in the handle.
The optional stands also offers dumbbell storage convenience and ease of weight selection.

• The Pro 100 dumbbell consists of three major components; the weight stack, handle and selector pin (Image 9).
Image 9
• The selector pin is tethered to the first weight plate/rail (Image 10). This is one of many safety features built into the
design of the product and must not be compromised.
DANGER: Do not remove selector pin from tether cord. It must remain attached to the first weight plate
(Image 10).
Page 7 of 13

Image 10
• The dumbbell uses a variable weight handle that can be 5, 7.5 or 10 lbs (Image 11). This allows the user to micro
load or "fine tune" their weight selections.
DANGER: When you choose to "open" the handle to remove Adder Weights, be sure to have the handle
pointed up as shown at right to prevent adder weights from falling out. Always keep Auto Lock in "closed"
position when out of weight stack (Image 11).
Image 11
• To remove the Chrome Weights from the handle, push the Auto Lock lever down (Image 12). Remove both Chrome
Weights to make handle weigh 5 pounds. Remove one Chrome Weight to make handle weigh 7.5 pounds. Chrome
Weights each weigh approximately 2.5 pounds.
Image 12
• Image 13 shows handle in the "open" position which enables the two Chrome Weights to come out of handle. This
allows you to "fine tune" or "micro-load" your weight adjustments. The Chrome Weights are included in the Pro 100
dumbbell handles.
Page 8 of 13

Image 13
Using the Pro 100 Dumbbells
1. Set the handle weight by either having the handle empty (5 lb), 1 Chrome Weight in the handle (7.5 lbs) or 2
Chrome Weights in the handle (10 lbs). Use the Auto Lock lever to take Chrome Weights out or put them in (Image
14).
WARNING: Be sure to always put Auto Lock lever in closed position before using, failure to do so could
result in falling weights or injury.
Image 14
2. Refer to color coded weight chart on each handle to select desired weight (Image 15).
NOTE: Weight shown is with Chrome Weights in handle.
Image 15
3. To choose/add weight plates from the nested weight stack, insert the selector pin into the colored side rail of the
weight desired (Image 16).
Image 16
Page 9 of 13

4. Lift weight straight up from center handle only (Image 17). Always check to insure that the weight selector pin is
fully inserted into the weight stack. Lift handle and weights five (5) inches above the nest and visually inspect for
correct placement of weight selector pin. If pin is improperly located, return weighted handle to weight stack and
correctly insert selector pin.
DANGER: Lift from handle only. Lifting from any other part of the dumbbell may result in falling weights
and/or injury.

Approved and Compatible Cleaners
Two preferred cleaners have been approved by reliability experts: PureGreen 24 and Gym Wipes. Both cleaners will
safely and effectively remove dirt, grime and sweat from equipment. PureGreen 24 and the Antibacterial Force
formula of Gym Wipes are both disinfectants that are effective against MRSA and H1N1.
PureGreen 24 is available in a spray which is convenient to use. Apply the spray to a microfiber cloth and wipe down
the equipment. Use PureGreen 24 on the equipment for at least 2 minutes for general disinfection purposes and at
least 10 minutes for fungus and viral control.
Gym Wipes are large, durable pre-moistened wipes to use on the equipment before and after workouts. Use Gym
Wipes on the equipment for at least 2 minutes for general disinfection purposes.
Contact Customer Support Services to order these cleaners (1-800-351-3737 or email:
customersupport@lifefitness.com).
Mild soap and water or a mild non-abrasive household cleaner can also be used to clean the display and all exterior
surfaces. Use a soft microfiber cloth only. Apply the cleaner to the microfiber cloth before cleaning. DO NOT use
ammonia or acid based cleaners. DO NOT use abrasive cleaners. DO NOT use paper towels. DO NOT apply cleaners
directly to the equipment surfaces.
Dumbbell Care
• Do Not strike Pro 100 dumbbells together and/or against other pieces of equipment.
• Do not drop the dumbbells. Dropping the weight plates from a height of more than 12 inches will void the
warranty.
WARNING: Striking Pro 100 dumbbells could dislodge pins and result in falling weights and/or injury.
Failure to replace worn parts may result in injury. Check/tighten all hardware prior to use.
