Step1.
Gingerly remove the motor back cap. Unscrew the x4 screws holding it to the frame while holding onto
the front motor cap and blade/cage assembly so that it does not fall forward. After the x4 screws are
removed, you may need to pull forward the front cap assembly a 1/4” to pull off the motor back cap. DO
NOT MOVE THE MOTOR HEAD ASSEMBLY SIDE TO SIDE, DOING SO WILL STRIP OSCILLATION
MOTOR GEARS. When the back motor cap is fully removed, replace one of the just-removed screws
back into the front motor cap and frame assembly temporarily to hold the front motor cap and blade/cage
in place while you grease your oscillation mechanism.
Matthews Fan CO Atlas brand oscillation fans are mechanical and
so, depending upon the amount of use your new fan receives and
the climate in which it is installed, it may need its oscillation
mechanism greased approximately every 6 months or as needed if
oscillation noise occurs.
Step2.
Use a lithium based grease on all moving parts and joints of the oscillation mechanism - the push arm
and cam of the oscillation motor.
Step3.
To replace the motor back cap, hold onto the front motor cap and blade/cage assembly. Remove the
temporary screw and align the screw holes between the front and back caps. Replace and tighten the x4
screws.
