Maintenance and Lubrication Schedule

Maintenance and 
lubrication procedures 
must be performed as 
speci

fi

ed by an 

authorized service 
technician.  Failure to 
do so may result in 
serious bodily injury 
and/or property 
damage.

WARNING

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 the transit agency daily service program.  Simple 
inspections can detect potential problems.  

The maintenance and lubrication procedures speci-

fi

ed in the following schedule must be performed by a 

Braun authorized service representative at the sched-
uled intervals according to the number of cycles.  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 speci

fi

ed in the 

previous sections should be repeated.  Clean com-
ponents and the surrounding area before applying 
lubricants.  LPS2 General Purpose Penetrating Oil is 
recommended where Light Oil is called out.  Use of im-
proper lubricants can attract dirt or other contaminants 
which could result in wear or damage to the compo-
nents.  Platform components exposed to contaminants 
when lowered to the ground may require extra atten-
tion.  Lift components requiring grease are lubricated 
during assembly  procedures.  When replacing these 
components, be sure to apply grease during installation 
procedures.  Speci

fi

ed lubricants are available from 

The Braun Corporation (part numbers below).

All listed inspection, lubrication and maintenance 
procedures should be repeated at 750 cycle intervals 
following the scheduled 4500 cycle maintenance proce-

dures.  These intervals 
are a general guideline 
for scheduling mainte-
nance procedures and 
will vary according to 
lift use and conditions.  
Lifts exposed to severe 
conditions (weather, 
environment, contami-
nation, heavy usage, 
etc.) may require 
inspection and main-
tenance procedures 
to be performed more 
often than speci

fi

ed.

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 but-
ton (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 
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.  One of our national Product 
Support representatives will direct you to an autho-
rized service technician who will inspect your lift.
