IV. COMPLETION PROCEDURES
A. TEST ARMREST CONTROL SWITCH
STEP 1: Ensure that the unit travels correctly by operating the armrest control switch while standing in front of the unit.
STEP 2: Depress the switch in the upstairs direction to move up. The lift will beep, wait three (3) seconds and begin to smoothly accelerate upwards. The lift will continue to move upwards as long as the switch is depressed.
STEP 3: Release the switch and the lift will come to an immediate stop.
STEP 4: Depress the switch in the downstairs direction to move down. The lift will beep, wait three (3) seconds and begin to smoothly accelerate downwards.
STEP 5: Release the switch and the lift will come to an immediate stop.
STEP 6: Run the chair all the way up and down the rail to ensure that the top of the seat back has at least a 1/2” clearance from the wall and any obstructions.
CAUTION! Do not ride on the chassis or lift until the install is complete.
B. TIGHTEN BRACKETS
STEP 1: Install and fully tighten the rail bracket mounting screws (four (4) screws per bracket). For hardwood stairs, a pilot hole should be drilled first. For plywood or particle board stairs care must be taken to prevent stripping.
C. SET UPPER AND LOWER TRAVEL LIMITS
STEP 1: Test the lower travel limit by operating the lift downward, keeping the switch depressed. The unit should begin to decelerate about 3” from its final resting position and stop clear of the floor.
STEP 2: The final stopped position can be adjusted to accommodate the height of the user by repositioning the limit cam located in a slot in the rail.
STEP 3: Use a 5/64” Allen wrench to loosen the set screw in the limit cam. Adjust the limit cam up or down and retighten the set screws. Repeat the above steps until the lift stops in the desired position.
Pinnacle Stair Lift manual | | www.Harmar.com | 866-351-2776 13
STEP 4: Repeat the above steps to set the upper limits. For safety, the footrest should be set at least level with the upper landing.
STEP 5: The optimum position is met when the seat height above the floor is the same at the top and bottom of the stairs.
D. TEST SAFETY STOP SWITCHES
STEP 1: Safety stop switches are located in both the upward and downward ends of the chassis providing protection from obstructions on the rail.
STEP 2: Safety stop switches are located in the footrest bottom pan providing protection from obstructions and trapping hazards on the stairs.
STEP 3: A safety stop switch is part of the swivel seat mechanism and prevents the lift from operating when the swivel is in use.
STEP 4: Test all the safety stop switches by driving the lift down and touching the downward end of the chassis, the lower edge of the footrest, and the underside of the footrest in both its folded and unfolded positions.
STEP 5: In each of the above cases the unit should come to an immediate halt. The LED indicator light on the armrest control should turn to orange and the unit should beep intermittently.
STEP 6: When the control switch is released, the unit should NOT be able to be driven in the direction that the lift initially engaged the obstacle. Test this condition.
STEP 7: Test to ensure that the lift can only be driven away from the obstruction. The LED indicator light will turn to green and stop beeping indicating a safe operating condition.
STEP 8: Repeat the above tests while driving the lift in opposite direction.
STEP 9: If any safety condition does not function properly, carefully review all installation instructions, reset the “ON /
OFF” switch and check that the LED indicator light is green. Repeat the above tests.
STEP 10: If any safety stop switch fails to immediately stop the lift and/or a red LED indicator light appears, remove the key to prevent further use of the lift and immediately call the manufacturer for assistance in diagnosing and repairing the problem. DO NOT USE THE LIFT.

E. ADDITIONAL SYSTEM CHECKS
STEP 1: After the successful testing of all safety switches, sit on the lift and operate to the top of the stairs.
Keeping the control switch depressed continuously, the lift should gently decelerate and then stop at the top of the track.
STEP 2: As a final adjustment, sit on the lift and do two (2) complete up trips and stop with the chair at the bottom. Then tighten the compression screw in the top end plate, then run the chair to the top and again tighten the compression screw. Run the chair to the middle and do a final tightening of the compression screw.
STEP 3: Drive the lift to the bottom, keeping the control switch depressed all the time, and check that the lift gently decelerates and stops so the footrest pan is clear of the floor. If necessary adjust the limit cams with a 5/64” Allen wrench.
STEP 4: Move the lift about three (3) feet from either the top or bottom of the rail. After 30 seconds the armrest
LED indicator light will show orange and beep indicating that the lift is not positioned on a charge point. The beep will stop after 30 seconds, but the armrest LED indicator light will continue to flash orange.
STEP 5: Test the seat swivel at the top by using the levers and swiveling the seat towards the landing and stop the seat at 35 and 85 degrees. The seat swivel levers will release into a locked position at each of these angles.
The lift will not operate in any of these positions if the control switch is depressed, and the LED indicator light will turn orange. Return the seat to its normal position and the LED indicator light will turn green and the lift will now operate normally.
STEP 6: Drive to the top or bottom and check the battery charging light. If the light is orange or red, the batteries are being charged.
THE LIFT IS NOW READY TO FOR USE.

V. FOLDING RAIL INSTALLATION
te!
A. RAIL INSTALLATION PREPARATION
TOOLS REQUIRED
The following is a suggested list of basic tools to have on hand during installation.
Wrenches
High torque drill
Allen wrenches (standard SAE set)
Carpenter’s square
Pencil
Tape measure
INCLUDED PARTS
Before beginning folding rail installation, please inspect and check the box contents. Please note that the Pinnacle
Parts Box is omitted on new units since these parts are factory installed on the stair lift. Report any damage to
Harmar or the freight carrier.
Rail Box:
• Assembled Folding Rail
Track Bracket Box:
• Two (or more) assembled short track brackets, rack pieces, two adjustable feet
Pinnacle Parts Box:
• Folding track side-plate
• Screw
• Modified front and rear Pinnacle safety switch bumpers. For new units, this box is
omitted and these parts are already installed on the stair lift.
16 Pinnacle Stair Lift manual | | www.Harmar.com | 866-351-2776
B. FOLDING RAIL INSTALLATION PROCEDURES
STEP 1: Orient the two track brackets onto the folding rail as shown at right, with the nuts on the same side as the folding mechanism (for either left or right folding).
STEP 2: Expand and snap the two brackets over the track, so the top is in the bracket-groove.
STEP 3: Tighten partially the two whiz nuts that position these on the track, using a ½ wrench (deep socket preferred), so they won’t slide when you’re test-fitting the position.
STEP 4: Place the track onto the stairway with the bottom bracket on the second step, as shown. Note that the bottom feet should approximately rest on the floor with the rail straight, but they will be adjusted later. If you’re adding the folding rail to an existing stairway, run the Pinnacle all the way to the top of the stairs so it is out of the way. Note that the track brackets install with the roundhead of the carriage bolts facing the stairs, the nuts are toward the wall. In this position, they are designed to lean the track slightly toward the wall.
STEP 5: Measure to verify that the underside of the rail is more than 2 inches from the stair noses, both at the second step bracket and at the upper bracket. If not, reposition the brackets as needed. This clearance is required for the stair lift footrest. In some installations, you may not be able to get 2 or more inches with the standard stair-bracket. Contact Harmar to get higher brackets.
Bottom bracket 2+ inches
STEP 6: Retrofits: FIT THE RAIL: If this is a new-install, the upper rail will be pre-cut at the factory to the correct length. If this installation is a retrofit to an existing stair lift, use a carpenter’s square to match-mark from the top of the folding rail to the point on the existing rail where it will have to be cut to splice.
Upper folding rail 2+ inches
Pinnacle Stair Lift manual | | www.Harmar.com | 866-351-2776 17
folding rail installation
STEP 7: Retrofits to existing stair lifts, measure how much you’ve marked to cut from the upper section, but don’t cut it at the splice because you’ll need to keep the countersunk holes. Instead, remove the very top cap and cut it from the top of the very top track piece.
Loosen the remaining brackets and slide the tracks all up so the new cut part is at the top where the old part was.
Measure from bottom, cut from the top
Don’t cut off these holes!
STEP 8: Retrofit to existing track, saw the track following the usual procedure, described in the installation manual.
STEP 9: Measure from the side of the rail to the wall. The minimum clearance that will work with a folding stair lift rail is 3 inches. Set the folding section of the stair lift rails to a distance of 3 inches from the wall or more. This will leave about 1/2 inch of clearance at the ball of the gas-spring.
STEP 10: Fasten down the near corner of the lower bracket using a drill that has extensions at least ten-inches long and a 3/8” socket.
STEP 11: Measure from the side of the rail at the upper bracket of the folding rail.
Also set this at 3 inches or more. Screw down one corner of the bracket.
Measure and set to three inches.
STEP 12: Install new or join to existing upper rail, following regular procedures
(this procedure is detailed in the Pinnacle Installation Manual (not shown). This procedure includes plugging the battery charging wire harness for the folding rail into the charging harness from the upper track. The charger itself can be plugged into either the top rail (for the top of the stairs), or to the charge plug from the folding rail, which comes out just higher than the folding mechanism for the bottom of the stairway.
STEP 13: Fasten down the other three bolts of both track brackets using the power drill and long extension with the 3/8” socket.

folding rail installation
STEP 14: Install and adjust the height of the two feet using a 9/16 open end wrench.
Set them so that both rest on the floor with the rail fully straight. The foot farther from the wall should be set a little taller than the inside one to get it to seat flat on the floor, since the Pinnacle track brackets intentionally lean the track toward the wall just a little.
STEP 15: If you’re installing the feet onto carpet, you may want to screw-down a piece of wood or metal to make the feet seat reliably. Otherwise, you can set the lift at the bottom of the rail and let it compress the carpet for a day, and then re-adjust the feet.
STEP 16: Carefully move the fork with your hand (don’t get pinched!) To make sure it operates smoothly. Watch it go to the floor. Make sure both feet sit fully on the floor. Make sure the hinge-joint is going fully straight.
STEP 17: Follow the normal procedure for installing track brackets and tightening them. This procedure (not shown here) is detailed in the Pinnacle Installation Manual.
STEP 18: Begin to install the folding rail parts onto the Pinnacle chassis. Shown here is just a bare Pinnacle chassis, to make the pictures more clear.
First, with a 5/16” Allen wrench, remove the two large black cap screws from the wall-side of the unit, then install the folding rail side-plate, but don’t tighten them yet.
STEP 19: Install the #8 screw, then tighten it and the two Allen head bolts. If your
Pinnacle stair lift is still installed on the track, you’ll have to use a short wrench and maybe a right-angle screwdriver.
Pinnacle Stair Lift manual | | www.Harmar.com | 866-351-2776 19
folding rail installation/folding rail Conversion
STEP 20: Remove both the front and the rear ‘bumpers’ from the Pinnacle chassis.
Switch them for the ones in the parts box. They both are attached with Phillips screws.
STEP 21: Test ride the unit a couple of times to verify that the folding rail is operating properly.
STEP 22: This completes this procedure. We recommend you use a household cleaner and paper towels to clean it before turning it over to the end user.
NOte!
The new Harmar folding rail for Pinnacle is designed so that all of the parts are ous’ and can be switched from one side to another in about 15 minutes by a skilled technician. Also, these pictures show the changes to the Pinnacle being made to a chassis that are not installed on a rail. There’s no reason that these changes cannot be made on a Pinnacle that is already mounted on a rail, but you may have to remove more items than are shown her ou encounter any problems or questions, call
