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 the transit agency daily service program.  Simple 

inspections can detect potential problems.  

The maintenance and lubrication procedures specified 

in this schedule must be performed by a BraunAbil

-

ity authorized service representative at the scheduled 

intervals according to the number of cycles.  

BraunAbility dual parallel arm lifts are equipped with 

hardened pins and self-lubricating bushings to de

-

crease 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 

components and the surrounding area before apply

-

ing 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 installation 

procedures.  Specified lubricants are available from 

BraunAbility (part numbers provided on previous 

page).

All listed inspection, 

lubrication and main

-

tenance procedures 

should be repeated 

at 750 cycle intervals 

following the scheduled 

4500 cycle maintenance 

procedures.  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, contami

-

nation, heavy usage, etc.) may require inspection and 

maintenance procedures to be performed more often 

than specified.  

Cycle Counter:

  NL-2 Series lift models are equipped 

with a cycle counter located on the top of the pump 

module.  This cycle counter allows the lift attendant/op

-

erator to easily track the number of cycles during daily 

inspections of the lift.  

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 

BraunAbility at 1-800-946-7513.  One of our Aftersales 

representatives will direct you to a BraunAbility autho

-

rized service technician who will inspect your lift.
