Winter is the time of year we receive calls regarding static electricity primarily on treadmills. In fact, many of the OEMs state they expect a certain amount of static, especially during this time of year.
Listed below are some of the sources which may be responsible for the static problems:
Items that gyms have control over:
- Worn motor brushes
- Worn belt/deck
- Lubrication maintenance
- Lack of humidity in the air
- Dusty climate
- Bad ground
- The unit should not be on the carpet
Suggested Solutions:
- If motor brushes are worn, replace
- If belt/deck are worn, replace
- Always keep belt/deck lubricated
- Run humidifiers in the gym
- Keep equipment as clean and dust-free as possible
- Check ground of machine (power outlet, power cord, drive motor)
- Install a rubber treadmill mat
Items that gyms have NO control over:
- Dehydration of user
- Dry skin of the user
- Wool or synthetic materials (nylon, spandex, polyester)
- The run pattern of the user (shuffling feet vs. smooth stride)
- Shoes
Suggested Solutions:
- Encourage users to drink more water to avoid dehydration (which results in dry skin)
- Encourage users to use lotion and drink more water (less friction with hydrated skin)
- Suggest users wear clothing of natural fibers (cotton)
- Suggest change in the run pattern
- Encourage wearing well-fitting shoes (old shoes may be too worn causing friction) and shoes without nylon mesh
It has also been recommended users spray themselves with a product such as Static Guard or mist themselves with a mixture of water and fabric softener to avoid static buildup. Allow for sprayed areas to thoroughly dry before using the treadmill.
