afety Information

nd workout recommendations for each piece of Tuff Stuff quipment prior to use.

) Consult with your physician before beginning any xercise program.

) Use proper discretion when children are present.

) Frayed or worn cables can be dangerous and may cause

jury. Periodically check these cables for any indication of ear.

) Inspect machine for any sign of parts or hardware ecoming loose.

Maintenance Information

1) Lubrication of all moving parts is essential to the longevit and optimal performance of your Muscle IV Home Gym. Initial lubrication of some parts of your gym have been done at the factory, but the weight stack guide rods must be lubricated at the time of assembly. We recommend a clear aerosol, silicone or Teflon spray.

Note: Do not use oil based lubricants as they will attract dust,dirt, and grime and will eventually gum up and erode bushings and sealed bearings.

2) All pulleys and bushings should be checked regularly for signs of wear.

3) Check and adjust tension on cables periodically as it will maintain proper anatomical function.

4) Periodically check all moving parts, upholstery and grips for wear. If replacement is necessary, please contact your local Tuff Stuff retailer or call our Customer Service Department.

5) As needed, upholstery may be cleaned with a mild solution of soap and water. Regular use of a vinyl treatment will add to the life and appearance of your upholstery.

6) All chrome plated surfaces should be cleaned regularly to prolong the life and luster of the finish. Wipe machine down with a damp cloth and dry thoroughly each day. At least once a week your chrome equipment should be polished with a commercial grade or automotive type chrome polish.

Tool Requirements

1) Two 3/4” Open-end wrenches

2) Two 9/16” Open-end wrenches

3) One rubber mallet

4) Needle nose pliers
