Platform Floor Level Position Adjustment:
1. Position platform at desired floor level position
(passenger loading/unloading height).
Note: Position platform such that:
a. the inner roll stop is laying flat on the threshold
plate
b. platforrm has not begun to fold
2. Turn Lift Power switch Off.
3. Press Floor Level Set button (located between
pump housing and lift tower).
4. While pressing the Floor Level Set button, turn the
Lift Power switch On.
5. Continue pressing the Floor Level Set button until
the lift sounds three “beeps.”
6. Release the Floor Level Set button.
7. Cycle lift to verify that platform stops at the set
floor level position.
Diagnostic codes have been established in event the
lift platform floor position does not set (the lift does not
sound three “beeps” - see Step 5 above). The control
board located inside the pump housing is equipped
with an LCD screen. Remove the pump cover to access the LCD screen. The following diagnostic codes
will help resolve floor position setting problems:
91 – The platform position is out of a prede-
termined acceptable range
92 – The Bridge Microswitch is not activated
(adjust switch or lower the platform)
94 – The Outer Barrier Up switch is not
activated (adjust switch)
95 – The Outer Barrier Latched sensor is not
activated.

Maintenance and Lubrication Schedule
Proper maintenance is necessary to ensure safe,
troublefree operation. Inspecting the lift for any
wear, damage or other abnormal conditions should
be a part of a regular service program. Simple
inspections can detect potential problems.
The maintenance and lubrication procedures specified in this schedule must be performed by a Braun
authorized service representative at the scheduled
intervals according to the number of cycles.
Braun dual parallel arm lifts are equipped with hardened pins and self-lubricating bushings to decrease
wear, provide smooth operation and extend the
service life of the lift.
When servicing the lift at the recommended inter-
vals, inspection and lubrication procedures specified
in the 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 these components
are replaced, grease must be applied during instal-
lation procedures. Specified lubricants are available
from The Braun Corporation (part numbers provided
above).

intervals 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
often than specified.
Maintenance Indicator: The Lift Ready green LED
mounted on top of the pump cover will begin to blink
after every 750 cycles. The blinking LED will not affect
the functions of the lift, but is a reminder to complete
necessary maintenance and lubrication.
Once the lift has been serviced, fully stow the lift. Once
stowed, press the UP button on the hand pendant and
the Floor Level Set button on the back side of the pump
cover until the Lift Ready green LED stops blinking.
Discontinue lift use immediately if maintenance
and lubrication procedures are not properly performed,
or if there is any sign of wear, damage or improper
operation. Contact your sales representative or call
The Braun Corporation at 1-800-THE LIFT. One of our
national Product Support representatives will direct you
to an authorized service technician who will inspect
your lift.
