Lift Operating Instructions

Before lift operation, park on a level surface, away from vehicular traffic. Place the vehicle transmission in “Park” and engage the parking brake.

Vehicle engine must be running.

If your lift does not function as intended or a visual or audible warning signal is activated, review the FMVSS 403/404 Certification

Checklist.

Refer to the Manual

Operating Instructions to manually operate lift. An NL Series lift is depicted in photos below. Operating procedures are applicable for other lift models.

Maintenance and Lubrication Schedule

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 specified in this schedule must be performed by a Braun authorized service representative at the scheduled intervals according to the number of cycles. Braun dual parallel arm 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 specified in the previous sections should be repeated. Clean 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 assembly procedures. When these components are replaced, grease must be applied during installation procedures. Specified lubricants are available from The Braun Corporation (part numbers provided above).

All listed inspection, lubrication and maintenance 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, contamination, heavy

WA

damage.

RNING

Maintenance and lubrication procedures must be performed as specified by an authorized service technician. Failure to do so may result in serious bodily injury and/or property usage, etc.) may require inspection and maintenance procedures to be performed more often than specified.

Cycle Counter: NL-2 Series lit models are equipped with a cycle counter located on the top of the pump module. This cycle counter allows the lift attendant/ operator 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

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.
