Maintenance and Lubrication
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 specified in
the following schedule must be performed by a Braun au-
thorized service representative at the scheduled intervals
according to the number of cycles. NHTSA NUVL Series
lifts are equipped with a cycle counter (digital display built
into the electronic control board).
NUVL Series 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 intervals,
inspection and lubrication procedures specified in the pre-
vious 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 as-
sembly procedures. When replacing these components,
be sure to apply grease during installation procedures.
Specified lubricants are available from The Braun Corpora-
tion (part numbers below).
All listed inspection, lubrication and maintenance proce-
dures should be repeated at “750 cycle” intervals following
Maintenance and lu-
brication procedures
must be performed
as specified by an
authorized service
technician.
Failure to do so may
result in serious
bodily injury and/or
property damage.
the scheduled “4500 Cy-
cles” maintenance. These
intervals are a general
guideline for scheduling
maintenance procedures
and will vary according to
lift use and conditions. Lifts
exposed to severe condi-
tions (weather, environ-
ment, 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 change color to yellow after every 750 cycles.
The yellow 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, press the CYCLE button
(located below LCD display on the control board) until the Lift
Ready LED changes back to green. The CYCLE button also
clears the lift cycle count (since last service) but not the lifetime
cycle count.
Discontinue lift use immediately if maintenance and lubrica-
tion 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-
