. PRESTART CHECKLIST
Lubricating Oil: Check crankcase oil level on dipstick- fill as needed to bring level up to Full mark.
Refer to Page 2. 1 for oil specifications.
Cooling System: On closed type cooling systems, remove radiator cap or cap on water cooled exhaust
manifold, then add clean fresh water until level is just below overflow tube. 7 to 7-l/2 quarts are
required for initial fill on radiator models, 5 to 57 f/2 quarts for heat exchanger models. If freezing
temperatures are anticipated, add antifreeze to radiator cooled and heat exchanger models. On direct
water cooled models, make sure cooling system is properly installed to insure sufficient coolant.
Direct systems are of the open type and cannot therefore be protected with antifreeze.

Use priming lever on fuel pump to prime system
before initial start up. On gas fueled plants, make sure system is properly hooked up before starting.
Refer to Fuel Section for typical arrangement and preliminary adjustments.
Battery: These elect&c plants feature exciter cranking which offers higher cranking speeds for
more positive starting. When battery current is applied to the generator, it functions as a motor and
cranks the engine during starting then is autotitically switched back to its generating function after the
e’ngine starts.
A 24 volt battery is required for DC generator models and a 12 volt battery for AC generator
models. 32 volt cranking is available for marine models. Connect the positive (t) terminal of the bat-
tery to the P terminal of controller and the negative (-) battery terminal to the N terminal on controller.

‘ITo start three-wire automatic start plants, it will be necessary to center tap the 120volt battery
or use two 67volt batteries to create a difference in voltage between leads Ll and L2. Without this,
both leads have to be connected to the battery positive (t) terminal, and cranking relays in L2 will not
operate when the voltage is the same. With the center tap, lead Ll is connected to battery + terminal,
L3 to the center tap and L2 to ground which is battery negative (0).
