Further Notes on Lubrication
Although a specific manufacturer’s brand of oil is listed in the Consumable Maintenance Materials
list (see
Consumable Maintenance Materials on page 47), similar oil by other manufacturers may be
used. Use the recommendations below for guidelines. Also, consult the oil manufacturer to ensure
your exact application needs are fulfilled.
Cold weather operation requires special oil considerations. Viscosity should not exceed 7500 SSU
(1620 CS) at lowest startup temperature. Continuous operation should range between 60-1000 SSU
(10.5 - 216 CS) for all temperature ranges.
Electrical System
The electrical system consists of numerous components connected by generic harnesses. Proximity
switches provide safety lockouts and work in conjunction with the operational controls located in the
control panel. The electrical control system activates air solenoid valves that in turn provide control
air pressure to the main hydraulic directional valve. In other words, the system may be described as
“electric over air over hydraulic”.
