5.5 HEAD SECTION
LIMIT SETTING – HEAD MOTOR
Required Tools:
Standard Screwdriver 5/16” Nut Driver 7/16” Open End Wrench
7/16” Socket
Procedure: (This procedure will take approximately 30 minutes)
1. Remove litter access panels 1 and 2 (see page 93).
2. Remove the motion interrupt panel (see page 95).
3. Run the head section down electrically until flat (0).
4. Lightly tap the Fowler down button until the bolt and bushing (E) are centered in the slot.
5. Unplug the power cord from the wall socket.
6. Using a 5/16” nut driver, loosen the two screws (A) on the cam (B).
7. Slide the cam toward the head of the bed just until the microswitch is activated (the switch will make a click-
ing noise).
NOTE
Check that the cam ”bump” is on the ”head” side of the switch actuator.
8. Tighten the two screws (A).
CAUTION
Be sure the head section stops when the ball nut bracket (C) is approximately 3/4” from panel (D). If not,
damage to the unit could result.
9. Run the head section fully up (60) electrically until it stops. If the upper limit is above 60, adjust the
cam guide (B) toward the foot end of the bed until 60 is achieved (the 3/4” space between (C) and (D)
must be maintained). If the lower limit is below 60, adjust the cam guide toward the head end of the bed
until 60 is achieved (the 3/4” space between (C) and (D) must be maintained).
10. Re–install the litter access panels removed in step 1.
