Installation Procedures
II. INSTALLATION PROCEDURES
A. DETERMINE OVERALL RAIL LENGTH (Only if track did not come pre-cut to length)
Step 1: Determine obstructions that will affect the position and length of the rail, such as walls, doors, hallway
orientation, etc.
Step 2: Measure the overall length of the stairs from the nose at the top landing to the oor (nose to oor
measurement, e.g., 128", see image below).
Step 3: For a normal stairway with adequate landing space, add 7" to the nose to oor measurement. This will
provide enough rail length to allow the stair lift to be adjusted so that the oor-to-seat height will be the same at
both the top and bottom (e.g., 141").
Step 4: If the top landing has restrictions (i.e., a wall or doorway), use the chart below to determine the length of
extension needed.
Step 5: To cut the rail, use a standard 12"chop saw, with a blade designed to cut aluminum. Do not cut rail
inside the house (aluminum chips are very hard to remove from carpets).
TIP! DO NOT cut the end of the rail that contains the joint holes.
Remove the charger strips and wire harness before cutting.

Installation Procedures
B. RAIL INSTALLATION
Step 1: Open the rail box and remove the contents.
Step 2: Position the bottom rail (with end plate attached) directly on the stairs with
the end plate towards the bottom of the stairs and the plastic rack facing up. Place an
object that measures between 3/4"and 1" between end plate and the oor.
Step 3: Position the two ends of the track close together. Locate and connect the plug on the ends of the two
charger harnesses inside the two track pieces.
Step 4: With the plastic rack facing up, slide the top rail into the bottom rail and guide them together using the
pre-installed pins. Gently tap the top rail if necessary to get them close together. Be
cautious not to pinch the charger harness.
Step 5: Install two (2) joint fasteners and rmly tighten with 3/16"Allen wrench. Then
slide rack pieces down to cover joint.
Step 6: Turn over joined rails and install the remaining two (2) joint fasteners and
rmly tighten with 3/16"Allen wrench. Then slide rack pieces down to cover joint.
TIP! Use the chair box or another heavy object, like a toolbox, at the bottom to prevent the
rail from sliding down the stairs.

Step 7: Install rail brackets by loosening the screws and snapping each bracket edge into the slot, or slide the
brackets on from the top of the rail.
Step 8:
A. For double rails, tighten the rst rail bracket in place so, when it’s turned
over, the back of the bracket touches the rear of the bottom step. Place and
tighten the second and third brackets on the steps on each side of the rail
joint, again so the back of the bracket touches the rear of the step. Place the
fourth and nal bracket on the top step before the landing, again tightening
it so it touches the front of the last step.
B. Tighten the rst rail bracket in place so when turned over the back of the
bracket touches the rear of the rst step from the bottom landing. Place the
other rail on the last step before the top landing, again tightening it so it
touches the rear of the last step.
Step 9: Turn the rail right side up (plastic side facing up).
Step 10: Measure any obstruction from the wall (this may include handrails,
molding, light switches, etc.) and adjust the edge of the brackets an equal distance
from the wall. The edge of the track needs to be 7"from the wall or any obstruction.

Installation Procedures
Step 11: The underside of the rail must be at least 2"above the stair tread nose to provide clearance for the
footrest. To achieve this 2” clearance move the rail and bracket forward. Once the clearance is 2"tighten
all bracket nuts to hold the brackets in position. To maintain the 2"clearance, and hold the rail in place, secure
the bottom bracket to the rst step from the oor with two 2"wood screws, using a 3/8"nut driver on a 6-10"
extension of a cordless drill.
C. CHASSIS INSTALLATION
Step 1: Remove plastic bag from chassis box. Lift the chassis with the manual override
hole (on bottom) facing the downhill side of the stairs and gently slide the chassis
onto the rail until it makes contact with the plastic rack. DO NOT LET THE CHASSIS
FREE FALL DOWN THE RAIL.
CAUTION! Be careful not to trap ngers between the rail and the chassis.
Step 2: Remove the safety tie and turn the red “ON/OFF” switch to the “ON” position (I).
Step 3: Use the installation switch (the black switch on the top of the chassis) to move
the chassis at least two (2) feet down the rail, pushing gently on the chassis to ensure
the chassis does not pull any rack to the top.
CAUTION! Do not ride on the chassis or lift until the install is complete.
TIP! Remove two pieces of gear rack from the top end of the track
before installing the chassis.

Installation Procedures
D. FINAL RAIL INSTALLATION
Step 1: Install the remaining plastic rack pieces in the upper rail.
Step 2: Use a hacksaw or chop saw to cut the last plastic rack piece ush with
the rail end. Place something on the oor to catch debris or mark and cut the
rack outside.
The exposed, cut end of the plastic rack should face the top end of the rail
(the factory-cut side should butt against the lower rack).
Step 3: Slide the top limit cam into one of the cam slots (either side), and
tighten the pre-inserted Allen screw with a 5/64"Allen wrench. This will
be used to set the nal upper limits for the stair lift.
Step 4: Remove charging strip from the rail box. Connect charging strip connector
to the charger wire that runs through the center of the rail from the lower charging strips.
Insert the two (2) charger strips into the keyed slots at the top of the rail (while standing on
the top landing looking down). The charging strip with the red wire should be inserted into
the left slot with the metal strip facing out. The charging strip with the black wire should be
inserted into the right slot with the metal strip pointing out.
Bend the red and black wire tabs in toward the center of the rack.
Insert excess cable into the rail, leaving the pigtail with the Molex connector.
Step 5: Install the end plate to the top of the rack with the four (4) self-cutting Torx
screws using the supplied T30 Torx bit.
TIP! Too much torque applied to these screws may result in damage.
Take your time and apply grease to threads.

Installation Procedures
Step 6: Install one of the rack pre-compression screws in the threaded hole in the top
rail plate; tighten as rmly as possible by hand with a 5/32"Allen wrench.
There are three (3) kinds of pre-compression screws:
1. 1/2"for tracks under 6'
2. 3/4"for tracks between 6’ and 12'
3. 1"for tracks over 12'
Step 7: Plug in the battery charger at either end of the rail, choosing
the closest or most convenient location of a wall power supply. Minimize
wire length and intrusion.
E. FOOTREST & SEAT INSTALLATION
Step 1: Remove footrest from box and use the installation switch to drive the chassis
downward to a position about 6" clear of the oor. This provides a safe area to install
and adjust the footrest. Do not drive the unit into bottom stop.
Step 2: Turn the red “ON/OFF” switch located on the top of the chassis to the
“OFF” position (0).
Step 3: Position the footrest onto the two (2) seat-leveling bolts on the
outside of the chassis by aligning the large opening at the slot ends of the footrest.
Step 4: Ensure the footrest is fully engaged.

Installation Procedures
Step 5: Position the rear seat support onto the two (2) seat-leveling bolts on the
backside of the chassis by aligning the large opening at the slot ends of the footrest.
Secure the rear seat support to the footrest/seat support using the two (2) hex-head
bolts and washers.
Secure the rear of the slider rails to the rear seat support using the two (2) socket
bolts.
Ensure that the seat support is level and tighten the two (2) front and two (2) rear
leveling bolts.
Step 6: Connect the footrest cable to the 6-pin connector on the chassis.
TIP! When the 6-pin footrest and the 8-pin chair cables are both connected to the chas-
sis, the black installation switch on the chassis is disabled and will not function.

Installation Procedures
Step 7: Align the seat rollers with the slider rails and slide the seat half way back.
Step 8: Swivel seat approximately 45°to one side.
Step 9: Attach the swivel pin bracket with the at side towards the footrest
support using the two (2) hex head bolts and washers. Ensure that one of
the swivel pins is engaged into the slot in the swivel cam.
Step 10: Connect the seat cable to the 8-pin connector on the chassis.

Step 11: If the lift is equipped with the optional key lock, ensure that the key
switch on the armrest control is in the locked position; the key should be in
the vertical position.
Step 12: Turn the red “ON/OFF” switch located on the top of the chassis to
the “ON” (I) position. You should hear a single beep and the LED indicator
light on the armrest control should cycle through a test sequence, showing red,
yellow and green respectively. If any of the system controls or safety sensors are
engaged the LED indicator light will turn to yellow.
Step 13: If the LED indicator light is not green, check the safety senors:
1. Seat swivel sensor (seat should be in the locked position)
2. Footrest lower sensor (check by pushing in on the safety pan on the footrest)
3. Upper foot pan safety sensor (check by pushing on the safety pan on the footrest).
4. Front foot pan safety sensor (check by pushing on the safety pan on the footrest).
5. Uphill safety sensor (ensure nothing is blocking upward passage)
6. Downhill safety sensor (ensure nothing is blocking downward passage)
If the LED indicator light is still not green after testing sensors, turn the unit off and recheck all wire plugs. Turn
the unit on again and recheck the LED indicator light cycle. When the LED indicator light remains green the lift is
ready to operate.

Remote Call/Send Control Operation
III. REMOTE CALL/SEND CONTROL OPERATION
A. REMOTE CONTROL OPERATION
The key switch on the arm of the chair must be in the “ON” position to use the
remote call/send control.
STEP 1: Press and hold the appropriate directional button on the front of the hand
control. The LED indicator light will turn green when a signal is being sent.
The chair lift will operate with or without a rider. All safety sensors on the chair lift are designed to continue to
operate in their normal mode. The LED light indicator on the armrest will also display the appropriate color.
STEP 2: If the chair lift fails to respond, this may indicate the batteries are discharged and need to be replaced.
Remove the back cover of the control and replace with commonly-available AAA batteries, ensuring that the
polarity is correct.
B. REMOTE CONTROL RE-PROGRAMMING
All call/send controls are factory programmed. Re-programming is not normally necessary during installation.
In the event that the remote call/send control needs to be re-programmed, it is essential to program BOTH
controls in one programming cycle. Do so by completing the following:
1. Start with the red “ON/OFF” switch in the “OFF” position (0).
2. Disconnect the 6-pin footrest and 8-pin chair wire harnesses from the chassis.
3. Press and hold the install switch (located on the top of the chassis) in either direction.
4. Turn the red “ON/OFF” switch to the “ON” position (I), and then release the install switch.
5. The lift will begin to beep rapidly (this means the rst remote control is ready to program).
6. Press and release the “UP” or “DOWN” button of the rst remote control (the rst remote control is now
programmed).
7. Press and release the “UP” or “DOWN” button of the second remote control (the second remote control is now
programmed).
8. Upon completion, two beeps will indicate that both remote controls have been programmed.
9. Turn the “ON/OFF” switch to the “OFF” position (0).
10. Connect the 6-pin footrest and 8-pin chair wire harnesses to the chassis and then turn the red “ON/OFF” switch to
the “ON” position (I).
11. Test each remote control in both the up and down directions.

Completion Procedures
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, drill a pilot hole rst. For plywood or particle board stairs, take care 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 nal resting position and stop clear of the oor.
STEP 2: The nal 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.

866-351-2776 | www.Harmar.com | | Pinnacle HD Stair Lift Manual 15
P/N: 75403 RevB 72618
Completion Procedures
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 oor 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.

Completion Procedures
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 nal 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 nal 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 oor. 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 ash 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 FOR USE.
