Guide rails, except those of elevators equipped with: oller or other type guiding members. not requiring lubrication, should be kept well lubricated; but an excess of lubricant should be avoided. Rails on which a lubricant is used should be cleaned down at least once a year. Where necessary, a non-flammable or high-flash-point solvent should be used to remove excess lubricant, lint, and dirt which will accumulate on them, and which presents a hazard in case of fire in the hoistway. Where sliding-type safeties are used it is important that guide-rails lubricant, or prelubricated or impregnated guide-shoe gibs where used, be of a type recommended by the manufacturer of the elevator which will not reduce the holding power of the car safety (See Part II, Section 205, Rule 205.16.) Rust-preventive compounds such as paint, mixtures of graphite and oil, and similar coatings should not be used as they may interfere with and in many cases will prevent proper operation of the car safety. Some substances may even cause complete failure of the safety to function. If it is considered necessary for any reason to use any of these substances, the manufacturer of the elevator should be consulted before applying it. 1000.1d - Oil Buffers
