ELECTRICAL CONNECTIONS AND WIRING
The electrical system of the hydraulic shapers consists of a motor for driving the main hydraulic pump, a motor to
power the table traverse and rail elevation, together with suitable push button station and magnetic switches for starting
the motors.
A wiring diagram shows the wiring which is considered standard; however, for your individual machine use only the
wiring diagram furnished for that machine.
When connecting the line wires to the control panel, jog the motors slightly to see that they run in the direction
indicated by the arrows attached to them. Remember that as yet the hydraulic system has no oil in it, therefore any more
than a slight jogging of the motor will be courting injury to the pump.
HYDRAULIC OILS
The oil used in the hydraulic system must be of a type proven suitable for the purpose. It should not foam nor
emulsify under constant agitation, should have high resistance to oxidation, and must be free from lint, chips, water,
sludge, and all other foreign substances. In addition it should meet the following specifications:
Viscosity Index ........................... 73 Min.
Viscosity ..................................... 300 S. S. U. at 100 F.
Pour Point................................... 10 F. Max.
Flash........................................... 355 F. Min.
Fire ............................................. 405 F. Min.
