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,

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

WARNING

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.

See the Maintenance/Lubrication Schedule for recommended applications per number of cycles.

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

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- THE LIFT®. One of our national Product Support representa- tives will direct you to an authorized service technician who will inspect your lift.
