bolts. Install and tighten the 4 #8-32 nuts to the bolts until the motor is
firmly seated to the guard.
3. Slide the propeller onto the motor shaft with the hub side of the prop fac-
ing the motor as shown in Figure 1. Do not tighten the screws. To center
the propeller between the front and rear guards, temporarily place the
front guard in its proper position. Center the propeller between the front

cised during installation, operation and maintenance. OSHA ap-
proved guards must be installed when fan is within reach of people
or within 8 feet (2.5 meters) of working level or when deemed advis-
able for safety. Guards currently installed on HAF12A4, Do not
