Hubbell Lift Chair Motor Installation

This is how we install Hubbell motors into liftchairs:

Put the chair in the full reclined position and tip it over upside down on the carpet.
(Stretch it out so it is fully out flat in the fully reclined position)
Take your old motor out and save the cleavis pins, spacers, and hair pins to use over.

Plug in your new motor and run it down as short as it will retract. Then hand tighten the stroke tube all the way down until it bottoms out against the gear box cover. Then bring it back out 4 full turns. ( I usually stick one of the cleavis pins back in so I can count 4 full turns).

Then attach the motor base to the lift chair base. You will find that the stroke tube will almost be lined up just right with the holes in the bracket on the recline bar where you reattach it. (This is because you have the chair stretched out as far reclined as it goes)

Then you hold the stroke tube so it does not turn and power it until it lines up with the holes on the recline bar where you reattach the new motor. (Be careful not to hurt your fingers, hold the tube firmly so the tube extends as the screw turns.)

Then turn your chair over and run it all the way up carefully and make sure the limit switch turns the motor all the way off automatically when it is in the full lifted position.

Then run the chair carefully down to the full reclined position and make sure the limit switch turns the motor all the way off automatically when it is in the full reclined position.

DO NOT LET THE MOTOR KEEP RUNNING IN EITHER THE FULL UP OR FULL RECLINE POSTION IF IT DOES NOT CUT OFF AUTOMATICALLY.

IF IT TRYS TO KEEP RUNNING YOU NEED TO MAKE SURE YOU STARTED WITH IT IN FULL RECLINE, MOTOR RETRACTED FULLY, AND STROKE TUBE BROUGHT OUT 4 FULL TURNS.

MAKE SURE THAT IN BOTH THE UP AND DOWN POSITION YOU DO NOT NOTICE EXCESSIVE STRAIN ON THE MECHANISM BEING PULLED TO TIGHT.

You can adjust the cam on the motor, to adjust the limit switches, if you have to do so, but, most likely you will not have to adjust it.
