Note
In order to maintain the adjustment of the low position when replacing a lift motor, a special tool kit must be used. The kit
includes alignment fixtures. To obtain this kit, contact our Customer Service department and order part number KR0154.
Tools Required:
• Tool Kit KR0154
• Cutting Pliers
• #2 Phillips Screwdriver
• Small Regular Screwdriver
• 1/2” Combination Wrench
• Bungee Cord (or equivalent)
Note
When raising or lowering any of the litter sections, ensure that all siderails are in the highest position. Unless otherwise
indicated, refer to Figure 10, page 1-44, for reference for this procedure.
1. Install the alignment fixtures (KR0154) on both sides of the brake mechanism on the base frame, under the lower
fixed frame.
2. Lower the bed, until the lower fixed frame is completely supported by the U-shaped pieces of the fixture (see Figure
9, page 1-44).
3. Remove the mattress and the plastic litter cover (if equipped) from the foot section metal frame.
4. Raise the fowler section to about 45°, and raise the thigh section to the highest position.
5. Fold the foot section back toward the head end of the bed. Secure it using a bungee cord.
6. Unplug the power cord from the wall receptacle.
