Safety

CAUTION: Practice safety in the operation and maintenance and use only approved

safety methods, materials and tools. Keep hands away from any pinch point or

undesignated areas; use only the provided handles for operating the elevator.

WARNING: Elevators which have experienced wear beyond established wear criteria set

by OEM, or are found to have cracks must be replaced or repaired by a BVM authorized

repair facility.

WARNING: Only original BVM parts may be used. Elevators are produced from cast

alloy heat treated steel and must not be welded in the field. Improper welding can cause

cracks and brittleness in heat-affected areas which can result in dramatic weakening of the

part and possible failure. Repairs involving welding and/or machining should be

performed only by a BVM authorized repair facility. Using an Elevator that has been

improperly welded or repaired is dangerous.

NOTE: The owner and user together with the manufacturer should jointly develop and

update inspection, maintenance, repair and remanufacture procedures consistent with

equipment application, loading, work environment, usage and other operational

conditions. These factors may change from time to time as a result of new technology,

equipment history, product improvements, new maintenance techniques and changes in

service conditions. Alternatively, BVM recommends using the Periodic inspection and

maintenance Categories and Frequencies as mentioned in API RP8B Table 1.
