Connecting The Battery 1/2 in ST-156 011-A / Ref. ST-188 448 / S-0756 + – Connect Negative (–) Cable Last. Tools Needed: OM-480 Page 15 4-3. Installing Muffler Pipe exh_pipe2 12/96 – ST-154 089-A / ST-154 611 / Ref. ST-188 448 Stop engine and let cool. Do not blow exhaust toward air cleaner or air intake. Top View 1/2 in Tools Needed: 4-4. Engine Prestart Checks Ref. ST-800 159-D Full 1/2 in (13 mm) Full Diesel Valve Open Check all fluids daily. Engine must be cold and on a level surface. Follow run-in procedure in engine manual. If unburned fuel and oil collect in exhaust pipe during run-in, see Section 9. Fuel Do not use gasoline. Gasoline will damage engine. Add fresh diesel fuel before starting engine the first time (see maintenance label for specifications). Fill fuel tank up to 1/2 in. (13 mm) from top to allow room for expansion. Open fuel shut-off valve. Do not run out of fuel or air enters fuel system and causes starting problems. See engine manual to bleed air from fuel system. Oil After fueling, check oil with unit on level surface. If oil is not up to full mark on dipstick, add oil (see maintenance label). Your unit may have the optional low oil pressure shutdown switch. However, some conditions may cause engine damage before the engine shuts down. Check oil level often and do not use the oil pressure shutdown system to monitor oil level. To improve cold weather starting: Keep battery in good condition. Store battery in warm area off concrete surface. Use fuel formulated for cold weather (diesel fuel can gel in cold weather). Contact local fuel supplier for fuel information. Use correct grade oil for cold weather. 4-5. Installing Ether Cylinder (Optional Ether Starting Aid) 5 4-6. Connecting To Weld Output Terminals .

Description Of Front Panel Controls (See Section 5-1) This unit has a max OCV control circuit that resets the Amperage/Voltage Control to maximum when the arc breaks. When an arc is struck, weld output control returns to the front panel or remote control setting. The Amperage/voltage Control adjusts amperage only when welding and does not adjust open-circuit voltage. 1 Ampere Range Switch Use switch to select weld amperage range. For most welding applications, use lowest amperage range possible to prevent arc outages. Do not switch under load. 2 Amperage/Voltage Control Control adjusts amperage within range selected by Ampere Range switch. Weld output would be 140 A DC with controls set as shown (50% of 90 to 190 A). 3 DC Voltmeter (Optional) 4 DC Ammeter (Optional) 5 Remote A/V Switch And Receptacle (See Section 5-3) 6 Magnetic Shutdown Switch (Optional) Use switch during start-up to bypass optional engine shutdown system.
