Starting/Shutdown Instructions
Starting the Engine
Be sure all Pre-Operation Maintenance has been per-
formed. Also, read the Engine Owner’s Manual.
Remove all loads connected to the AC power recepta-
cles. To start the engine, set the “Idler Control” switch
in the Automatic ( / ) position.
Use the choke control as follows:
Kohler Engine - Always pull the choke control out
when starting the engine; cold, warm or hot. Place the
“Engine” switch in the “ON” position.
Push the “START” button and crank the engine until it
starts. Release the button as soon as the engine
starts. Do not push the “START” button while the
engine is running because this will cause damage to
the ring gear and/or starter motor. After the engine
has started, slowly return the choke control to the full
“in” position (choke open).
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 WELD-
MARK 225 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 ( 5 ) HRS:
The oil filter is to be changed at the second oil
change. Refer to the Engine Owner’s Manual for more
information.
