Every 50 Hours of Use Weekly for Institutional Users

Lubricate the chain with a teaspoon of purified mineral oil, 3-IN-ONE® oil, or 20W motor oil. Apply oil to a paper towel, and rub the paper towel along entire length of chain. Wipe off the excess. Repeat if needed. Do not clean the chain with any kind of cleaner or solvent, e.g. WD-40®.

Every 250 Hours of Use Monthly for Institutional Users

  1. Inspect the chain for stiff links. If stiff links are found, and if thorough lubrication does not help, replace the chain.
  2. Inspect the chain-handle connection for wear. If the hole has become elongated, or the U-bolt is worn halfway through, replace the entire connection.
  3. Tighten the shock cord if the handle does not return all the way to the fan enclosure. See Shock Cord Adjustment.
  4. Check screws for tightness, including those used for assembly.
  5. Loosen or tighten the nuts on the Performance Monitor arm joints as necessary. See Performance Monitor Arm Tension Adjustment.
  6. Check for dust inside flywheel with a flashlight. Vacuum if needed. See Flywheel Opening and Cleaning.
