Inner Roll Stop Occupied Sensor Adjustment
1. The optimum setting for the inner roll
stop occupied sensor adjustment nut is
to have just enough pressure to fold and
unfold the inner roll stop without triggering the inner roll stop occupied sensor.
This provides the most weight sensitive
setting while allowing the unoccupied
inner roll stop to function correctly.

2. If the weight of the empty inner roll stop
is triggering the sensor while it is folding, tighten the sensor nut 1/8 turn and
cycle the lift several times to verify correct operation. See Photo J.
3. If the lift is not reacting to weight on
the inner roll stop soon enough, loosen
the pressure adjusting nut 1/8 turn and
cycle the lift several times to verify correct operation.

continues to go off even when the inner

Maintenance and Lubrication Schedule
Proper maintenance is necessary to ensure safe,
trouble free operation. Inspecting the lift for any wear,
damage or other abnormal conditions should be a part
of all transit agencies’s daily service program. Simple
inspections can detect potential problems.
The maintenance and lubrication procedures speciÀHGLQWKHIROORZLQJVFKHGXOHmust be performed
by a Braun authorized service representative at the
scheduled intervals according to the number of cycles.

When servicing the lift at the recommended intervals,

previous sections should be repeated. Clean the components and the surrounding area before applying
lubricants. LPS2 General Purpose Penetrating Oil is
recommended where Light Oil is called out. Use of improper lubricants can attract dirt or other contaminants
which could result in wear or damage to the components. Platform components exposed to contaminants
when lowered to the ground may require extra attention. Lift components requiring grease are lubricated
during assembly procedures. When replacing these
components, be sure to apply grease during instalODWLRQSURFHGXUHV6SHFLÀHGOXEULFDQWVDUHDYDLODEOH
from The Braun Corporation (part numbers provided on
previous page).
All listed inspection, lubrication and maintenance procedures should be repeated at “750 cycle” intervals
750
Cycles
Page 12
following the scheduled
“4500 Cycles” maintenance. These intervals
are a general guideline
for scheduling maintenance procedures and
will vary according to lift
use and conditions. Lifts
exposed to severe conditions (weather, environment, contamination,
heavy usage, etc.) may
require inspection and
maintenance procedures
to be performed more

Public Use Wheelchair Lifts
Braun “Worry-Free”
Three-Year Limited Warranty
The Braun Corporation of Winamac, Indiana, warrants its wheelchair lift against
defects in material and workmanship for three years, providing the lift is operated and
maintained properly and in conformity with this manual. This warranty is limited to the
original purchaser and does not cover defects in the motor vehicle on which it is installed,
or defects in the lift caused by a defect in any part of the motor vehicle.
This warranty commences on the date the lift is put in service, providing the
warranty registration card is completed and received by The Braun Corporation within 20
days of purchase.
This warranty also covers the cost of labor for the repair or replacement of most
parts for one year when performed by an authorized Braun Representative. (A Braun labor
schedule determines cost allowance for repairs.)
This warranty does not cover normal maintenance, service, or periodic adjustments
necessitated by use or wear. The Braun Corporation will not, under any circumstances, pay
for loss of use of lift or vehicle in which it is installed or loss of time.
This warranty will become null and void if the lift has been damaged through
accident, misuse, or neglect, or if the lift has been altered in any respect.
Return Authorization Procedure
When processing any warranty claims (parts, repairs, etc.), all requests must be processed through The
Braun Corporation Product Support Department. Call 1-800-THE LIFT ® (extension 3009) during normal
working hours. Product Support will issue a Return Material Authorization (RMA) number and detail the
procedures required for processing returns and/or authorizing credit.
The lift identification information is provided on the Braun Serial No./Series No. identification tag and
the two warranty cards (shown on inside front cover). The lift identification information must be
provided when filing a warranty claim or ordering parts.
