MAINTENANCE
DANGER
ALWAYS SHUT OFF THE FAN AND UNPLUG IT FROM ITS POWER SOURCE TO PREVENT ACCIDENTAL STARTING
AND THE POSSIBILITY OF ELECTRICAL SHOCK AND/OR ELECTROCUTION. BE SURE THE FAN BLADE HAS
STOPPED ROTATING BEFORE PLACING ANY OBJECTS OR FINGERS NEAR THE FAN GRILL.
I. Visually check all fasteners and individual components for loose or broken parts. Tighten or replace items as required, with
genuine, factory approved replacement parts only.
2. Keep the Fan blade clean from debris. Accumulation of dust, dirt, paint, etc. on the Fan blade will throw the blade rotation
out of balance resulting in damage. To clean the Fan blade, be sure the plug is disconnected and the blade has stopped
rotating. Remove one grill and wipe blade and interior shell housing clean of debris with a damp cloth and mild liquid soap.
Dry all parts thoroughly. DO NOT PRESSURE WASH THE FAN. Replace grill prior to next operation.
DANGER
DO NOT OPERATE THE FAN WITHOUT THE INLET AND OUTLET GRILL PROPERLY IN PLACE.
3. Contact Schaefer directly for Fan maintenance or repair not described in this manual (or if you are unsure whether
maintenance is required.) at Tel# (320) 251-8696 or at www.schaeferfan.com.
