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 speci￿ed 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 speci￿ed 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.

Speci￿ed 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 Indicator: A Lift Ready green LED is mounted on the hand-held

pendant storage bracket. The green LED 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 perform necessary maintenance and lubrication procedures.

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.
