MAINTENANCE and LUBRICATION

Maintenance and Lubrication Introduction

Proper maintenance is necessary to ensure safe, trouble-free operation. Inspecting the ramp for any wear, damage or other abnormal conditions should be a part of all transit agencies daily service program (preventive maintenance). Simple inspec- tions can detect potential problems.

A generic Daily Preventive Maintenance Sched- ule is provided in this manual for transit agency use. The form can be tailored to your particular application. Preventive maintenance visual inspec- tions do not take the place of the procedures speci- fied in this schedule.

The maintenance and lubrication procedures speci- fied in this schedule must be performed by a Braun authorized service representative at the scheduled intervals according to the number of cycles or elapsed time, whichever comes first.

RA500 ramps are equipped with hardened pins and self-lubricating bearings to decrease wear, provide smooth operation and extend the service life of the ramp.

Clean the components and the surrounding area before applying lubricants. LPS2 General Pur- pose 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. Ramp com- ponents exposed to contaminants when lowered to the ground may require extra attention. Specified lubricants are available from The Braun Corporation (part numbers provided on page 30).

Recommended Intervals: These intervals are a general guideline for scheduling maintenance pro-

cedures and will vary according to ramp use

and conditions. Transit agencies operating vehicles equipped with ramps that are not monitored by cycles may choose to have the ramp system main- tained on the same schedule as the vehicle (routine maintenance). Doing so ensures the ramp is being main-

tained regularly.

When servicing the ramp at the consecutive recom- mended intervals, inspection and lubrication proce- dures specified in the previous sections should be performed (repeated). All listed inspection, lubrication and maintenance procedures should be repeated at “8 Weeks or 200 Cycles” intervals following the scheduled “1 Year or 1250 Cycles” maintenance.

Lifts exposed to severe conditions (weather, environ- ment, contamination, heavy usage, etc.) may require inspection and maintenance procedures to be per- formed more often than specified.

Discontinue ramp 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 ramp.
