Pride and workmanship go into every product to provide
our customers with quality products. It is possible, however,
that during its lifetime a product may require service.
Products should be serviced only by a qualified service
technician who is familiar with the safety procedures
required in the repair and who is equipped with the proper
tools, parts, testing instruments and the appropriate service
manual. REVIEW ALL SERVICE INFORMATION IN THE
APPROPRIATE SERVICE MANUAL BEFORE
BEGINNING REPAIRS.
Only personnel that have been trained to install, adjust,
service, maintenance or repair (hereinafter, "service")
