Test Safety Stop Switches; Additional System Check - Harmar Mobility PINNACLE SL300 Series Installation & Service Manual

TEST SAFETY STOP
SWITCHES
1. 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)
2. Safety stop is located in the footrest providing
protection from obstructions and trapping
hazards on the stairs.
3. A safety stop switch is part of the swivel
seat mechanism and prevents the lift from
operating when the swivel is in use.
4. 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)
5.
In each of the above cases the unit should come to
an immediate halt and should beep intermittently.
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.
7. Repeat the above tests while driving the lift in the
opposite direction.
8.
If any safety condition does not function properly,
carefully review all installation instructions, reset
the "On/Off" switch. Repeat the above tests.
9.
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.

ADDITIONAL SYSTEM
CHECK
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
pressed continuously, the lift should gently
decelerate and then stop at the top of the rail.
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.
3. Drive the lift to the bottom, keeping the
control switch pressed all the time, and check
that the lift gently decelerates and stop so the
footrest pan is clear of the floor. If necessary
adjust the limit cams with a 5/64" Allen wrench.
4. Move the lift about 3' from either the top
of bottom of the rail. After 30-seconds the
beep indicating that the lift is not positioned
on a charge point. The beep will stop after
30-seconds.
5. Test the seat swivel at the top using the levers
and swiveling the seat towards the landing
and stop the seat at 35� and 85�. 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 pressed. Return the seat to its
normal position and the lift will now operate
normally.
