4. Disconnect motor pigtail from extension on lift frame at quick release. Remove all wire clamps or Tywraps.
5. Disconnect push tube from recline bar by removing hair pin and clevis pin.
6. While supporting motor, remove hair pin from clevis pin, then pull clevis pin out from motor lift frame. Remove motor.

INSTALLATION

1. Align back of motor to back part of lift frame, replace clevis pin into motor and frame, then hair pin.
2. Replace wire clamps, reconnect pigtail to extension on lift frame.
3. Untape push tube from dust cover on motor assembly.
4. Plug motor power cord into wall outlet.
5. Hold push tube firmly (not dust cover), push up-switch on hand wand until push tube hole aligns with recline bar. Replace clevis pins washers and hair pin.
6. Place chair back in upright position and run chair through full cycle.

PLEASE NOTE: Minor adjustments may have to be made to achieve full recline or lift. See resetting procedure for motor assembly in this manual. Take note for black or brown frame settings.

RESETTING MOTOR ASSEMBLY PRESENTLY IN LIFT CHAIR

1. If possible have chair in its sitting position.
2. Push chair on its back and lift footrest exposing front of lift frame and push tube on motor assembly.
3. Remove hair pin then clevis pin from push tube and recline bar.
4. While holding dust cover lightly (plastic sleeve) push paddle switch towards down on hand wand until motor shuts off. Replace clevis pin in push tube only.
5. Turn push tube manually down clockwise until worm gear bumps clevis pin.
6. Once worm gear hits clevis pin, manually turn push tube 2 complete turns counter-clockwise for brown frame LM3000 Series. For black round tube frame LM4000 Series turn push tube approximately 5 complete turns counter-clockwise.
7. Remove clevis pin from push tube, firmly grasp push tube, push up switch on hand wand until hole on push tube aligns with hole in recline bar.

Chairs Mfg.: From May 1997 to Current

PREPARATION STEPS

1) Inspect motor for 2 key areas;
  A) Forkhead is fully tighten to aluminum tube
  B) Turn aluminum tube counter clockwise to tighten and then turn clockwise one complete turn to set motor.
2) Make sure chair is on side, with hand wand side up, and in full recline position.

INSTALLATION STEPS:

Use only supplied 2 1/2" Clevis or Grade 8 Bolt

1) Transformer and plug connection on the left side of motor, (downward) install lower motor to base with the 1 5/8" clevis pin (lock in with hitch pin).
2) Plug in the new motor, connect hand wand cord connection, run motor in up position to expose the aluminum tube about 3" to 4".
3) Use only 3/8 clevis pin supplied, or the 3/8 bolt, grade 8 only, gold color, insert through motor bracket with nylon washers (ref. Diagram
  B. Lock in with hitch pin, or 3/8 nut to go with 3/8 bolt (ref. Diagram B).
4) Hand wand steps, diagram C
  A. Run cord over top of motor, lock cord with loop through rubber restraint devise on side of transformer (ref. Dia. C)
  B. Run hand wand through pocket
  C. Coils start at bottom edge of pocket. Exceptions: 751 Regals, Extra Wide chairs adjust as necessary.
  D. Clamp cord to bottom of arm.
  E. Measure 12" of coil cord below hand wand and hold at this point, then pull to quick release clamp and lock in.
  F. Staple pocket.
5) Tywrap AC power cord to lower base and Tywrap hand control cord to U Bar as in (Diagram C, about half way) make sure there is slack in hand wand straight cord.
6) Set chair upright and ride chair through 2 full cycles for proper functioning.

1. If possible, raise chair, to lift position to approximately half way or more.
2. Unplug chair from receptacle.
3. Push chair forward on its footboard.
4. Disconnect motors from each other and disconnect motor pig tail from extension.
5. Disconnect push tubes from top part of lift frame.
6. While supporting motor, remove hair pin and clevis pin at rear of motor and frame. Repeat for second motor.

Installation

1. Standing behind the chair, align motor with power cord to left side of lift frame, replace clevis pin through lift frame and gear casing of motor, insert hair pin to lock clevis pin into place.
2. Install second motor to the right in the same manner.
3. Connect motors together by plugging 6 pin connectors together.
4. Then plug 4 pin connector off right motor to 4 pin connector on the lift frame (The Extension).
5. Using a dowel rod approximately 3/8 x 16 inches long, insert it through both push tubes.
6. By holding rod between motors run motors down first by pushing down button on hand control.
7. If motors don’t move or run down, press up for 5 seconds then push down on controller till motors shut off.
8. Remove rod from push tubes, insert clevis pin into the left motor assembly.
9. Turn push tube down clockwise until the worm gear inside the push tube bumps the clevis pin. Then STOP!
10. Now turn the push tube counter clockwise 4 complete turns.
11. Repeat numbers 8 through 10 for the right side motor.
12. Remove clevis pin from right motor, reinsert 3/8 x 16 inch rod through right and left motor push tubes.
13. Holding rod between both motor assemblies push up on the hand wand extending push tubes out until they meet up with the top piece assembly of the lift frame.
14. Remove the 3/8 x 16 inch rod from both push tubes.
15. Working with left motor first (Master Motor) reinsert clevis pin and nylon spacers back into the top piece and push tube of lift frame. Insert hair pin to lock clevis pin.
16. Go to right motor (Slave Motor) align clevis pin and nylon spacers with motor push tube and insert clevis pin through. Lock in clevis pin with hair pin.

Please Note:
You may run into trouble aligning the clevis pin through the left motor. It may be necessary to turn that push tube clockwise or counter clockwise.

1. Attach back gear casing of motor to lower base of lift frame.
2. Connect 4 pin pig tail off motor to 4 pin connector of extension plug
motor assembly into outlet.
3. While holding push tube on motor, run motor assembly down using the
hand control till motor shuts off. Please note if motor won’t run down, go up first, then run it down.
4. Insert clevis pin through end of push tube and turn tube down until it bumps the worn gear inside push tube. Stop!
5. Turn tube back out until it reaches 14 inches in length measuring from front of gear casing to end of push tube.
