STARTING THE ENGINE
NOTE: Remove all loads connected to the AC power
receptacles before starting the diesel engine.
1. Open the engine compartment door and check
that the fuel shutoff valve located above the clear
plastic fuel filter housing is in the open position
(lever in the vertical position). See Figure B.3.
2. Check for proper level of coolant in the plastic
reserve overflow tank. The level should be
between the full and the low marks.
3. Check for proper oil level on the oil dipstick. Close
engine compartment door.
4. Set “IDLER” switch to “AUTO”.
5. Set the “ENGINE” switch to “ON”. Observe that
both the oil pressure light and battery charger light
are on. Check the fuel gauge to make sure that
there is an adequate fuel level (NEVER ALLOW
THE RANGER 10-LX TO RUN OUT OF FUEL).
6. Press the “GLOW PLUG” button for 15
seconds (30 seconds if below 0°C/32°F)
and then press the “START BUTTON”.
7. Release both buttons when the engine
starts.
8. Check that the indicator lights are off. If not,
immediately stop the engine and investigate the
indicated problem.
9. Allow the engine to warm up at low idle speed for
several minutes before applying a load and/or
switching to high idle. Allow a longer warm up
time in cold weather.
NOTE: If the engine fails to start in 60 seconds or
stops running, the “ENGINE” switch must be switched
to “OFF” and then switched back to “ON” before
attempting to restart the engine. This resets the
engine protection circuit.
If the engine will not start, see the Trouble-
shooting section of this manual.
STOPPING THE ENGINE
1. Remove all welding and generator
power loads and let the engine cool by
running it for several minutes at low idle.
2. Stop the engine by placing the Engine Switch in
the OFF position. This turns off the fuel solenoid.
You can also stop the engine by turning off the fuel
valve located on the fuel filter housing.
BREAK-IN PERIOD
Any engine will use a small amount of oil during its
“break-in” period. For the diesel engine on the
RANGER 10-LX, break-in is about 50 running hours.
Check the oil every four hours during break-in.
Change the oil after the first 50 hours of operation,
every 100 hours thereafter. Change the oil filter at the
second oil change. For more details, see the
Maintenance section of this manual.
During break-in, subject the RANGER 10-LX to mod-
erate loads. Avoid long periods running at idle. Before
stopping the engine, remove all loads and allow the
engine to cool several minutes.
