Electronics Course    
     
The Oilgear Company has conducted electronics courses as a service to our customers for many years. Under the guidance of experienced engineers and technicians, using modern teaching methods, many people have been instructed in the operation and application of Oilgear electronic modules; studied complete servo systems; and have been given recommendations on preventative maintenance, adjustment, trouble shooting, and repair.
 

Oilgear electronic modules are designed and built for many years of precise and reliable service. Each component is carefully assembled, inspected and tested under meticulous quality control. However, performance and long service life can be impaired by misapplication, improper installation and improper adjustment.

By applying instructions received in The Oilgear Electronic Course, operating and maintenance personnel can correct or eliminate malfunction and premature failures while using Oilgear equipment to their best advantage. We strongly recommend The Oilgear Fluid Power Course be completed before taking The Oilgear Electronic Course (which assumes a good background in hydraulics).

Employees of companies using Oilgear equipment, original equipment manufacturers, and personnel of prime contractors associated with Oilgear may apply for the Course. Each student must be sponsored by his employer. Class sizes are limited and reservations are necessary. Students must pay their own transportation, hotel, and living expenses. Lunches and snacks will be provided by The Oilgear Company during school sessions.

Friday afternoon a special period is set aside to aid our customers with special electronic circuit applications or problems. To conduct this special help period, we require advance notice, the Oilgear drawing number for the circuit and a short description of the help required. (Additional form provided).

Since parts of this course involve shop work, students should wear appropriate clothing. Our safety rules (for touring the manufacturing area) require shoes that have hard soles, low heels and not have a webbed type top, open-toed, or tennis/basketball types.
