STARTING THE ENGINE

WARNING

•Do not touch electrically live parts of electrode with skin or wet clothing.

•Keep flammable material away.

•Insulate yourself from work and ground. Wear eye, ear, and body protection.

•Keep your head out of the fumes.

• Use ventilation or exhaust to remove fumes from breathing zone.

Be sure all Pre-Operation Maintenance has been per- formed. Also, read the Engine Owner’s Manual before starting for the first time.

Remove all loads connected to the AC power recepta- cles. Use the choke control as follows:

KOHLER ENGINE - Always pull the choke control out when starting the engine; cold, warm or hot.

Turn the engine switch to the “start”position and crank the engine until it starts. Release the switch as soon as the engine starts, slowly return the choke control to the full “in” position (choke open),

and turn the switch to the Auto Idle( / ) position. Do not turn the switch to the “start” position while the engine is running because this will cause damage to the ring gear and/or starter motor

After running at high engine speed for 10-14 seconds, the engine will go to low idle.

Allow the engine to warm up by letting it run at low idle for a few minutes.

STOPPING THE ENGINE

Remove all welding and auxiliary power loads and allow engine to run at low idle speed for a few minutes to cool the engine.

Stop the engine by placing the Engine switch in the

“OFF” position.

A fuel shut off valve is not required on the Ranger® 250 GXT because the fuel tank is mounted below the engine.

bREAK-IN PERIOD

It is normal for any engine to use a greater amount of oil until the break-in is accomplished. Check the oil level twice a day during the break-in period (approxi- mately 50 running hours).

IMPORTANT: IN ORDER TO ACCOMPLISH THIS bREAK-IN, THE UNIT SHOULD bE SUbJECTED TO MODERATE LOADS, WITHIN THE RATING OF THE MACHINE. AVOID LONG IDLE RUNNING PERIODS. REMOVE LOADS AND ALLOW ENGINE TO COOL bEFORE SHUTDOWN.

The engine manufacturer’s recommendation for the running time until the first oil change is as follows:

KOHLER

CH23S

5 HRS

The oil filter is to be changed at the second oil change. Refer to the Engine Owner’s Manual for more information.
