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.

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 all transit agencies’s daily service program.  Simple 
inspections can detect potential problems.  

The maintenance and lubrication procedures speci

fi

ed 

in this schedule 

must

 be performed by a Braun autho-

rized service representative at the scheduled intervals 
according to the number of cycles.  

Braun dual parallel arm lifts are equipped with hard-
ened 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

 the 

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.  Speci

fi

ed lubricants are available from 

The Braun Corporation (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 Cycles” mainte-
nance.  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, contamina-

tion, heavy usage, etc.) may require inspection and 
maintenance procedures to be performed more often 
than speci

fi

ed.

Cycle Counter:

  NCL-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 opera-
tion.  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.
