DISCONNECT POWER AND BATTERIES BEFORE PERFORMING ANY MAINTENANCE OR REPAIR TO THE
ACTUATORS
MAINTENANCE - Inspect the screw-drive gears for lubrication, debris and cleanness at least once a year. For
actuators installed in areas where dirt and dust are a concern, maintenance should be done at shorter intervals.
Keep the screw-drive lubricated using BFT grease I101115. Do not apply grease if gears are dirty. If necessary,
clean with solvent before applying.
