Tighten Brackets; Set Upper And Lower Travel Limits; Test Safety Stop Switches - Harmar Mobility SL600 Installation & Service Manual

PINNACLE STAIR LIFT: SECTION 5
COMPLETION PROCEDURES

TIGHTEN BRACKETS

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.
SET UPPER AND LOWER
TRAVEL LIMITS
1. Test the lower travel limit by operating the lift
downward, keeping the switch pressed. The
unit should begin to decelerate about 3" from
its final resting position and stop clear of the
floor.
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.
3. Use a 5/64" Allen wrench to loosen the set
screw in the limit cam. Adjust the limit cam
up or down and re-tighten the set screws.
Repeat above steps until the lift stops in the
desired position.
4. Repeat the above steps to set the upper limit.
For safety, the footrest should be set at least
level with the upper landing.
5. The optimum position is met when the seat
height above the floor is the same at the top
and bottom of the stairs.

Safety stop switches are located in both the
upward and the downward ends of the chassis
providing protection from obstructions on the
rail. (Folding rail model)
Safety stop is located in the footrest providing
protection from obstructions and trapping
hazards on the stairs.
A safety stop switch is part of the swivel
seat mechanism and prevents the lift from
operating when the swivel is in use.
Test all 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. (Folding rail model)
In each of the above cases the unit should come to
an immediate halt and should beep intermittently.
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.
Repeat the above tests while driving the lift in the
opposite direction.
If any safety condition does not function properly,
carefully review all installation instructions, reset
the "On/Off" switch. Repeat the above tests.
If any safety stop switch fails to immediately stop
the lift, immediately call Harmar for assistance in
diagnosing and repairing the problem. Do not use
the lift.
