ENGINE OPERATION
DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS.
The maximum allowable high idle speed for the
RANGER 300 is 3700 RPM, no load. Do NOT adjust
the governor screw on the engine. Severe personal
injury and damage to the machine can result if it is
operated at speeds above the maximum rated speed.
Read and understand all safety instructions included in
the Kubota instruction manual that is shipped with your
RANGER 300.
BEFORE STARTING THE ENGINE
Check the engine oil level:
See Figure D.1 for location of dipstick.
1. Be sure the machine is on a level surface.
2. Remove the engine oil dipstick and wipe it with a
clean cloth. Reinsert the dipstick and check the
level on the dipstick.
3. Add oil (if necessary) to bring the level up to the full
mark. Do not overfill.
4. Replace the dipstick.
Check and fill the engine fuel tank:
DIESEL fuel can cause fire or
explosion.
• Stop engine when fueling.
• Do not smoke when fueling.
• Do not overfill tank.
• Keep sparks and flame away from tank.
1. Remove the fuel tank cap.
2. Fill the tank approximately 4 inches (100 mm) from
the top of the filler neck to allow for fuel expansion
(observe the fuel gauge.) DO NOT FILL THE TANK
TO THE POINT OF OVERFLOW.
3. Replace the fuel tank cap and tighten securely.
NOTE: DO NOT allow the RANGER 300 to run out of
fuel. If it does, you will have to bleed the injection sys-
tem. See the Maintenance section of this manual and
the Engine Operator’s Manual for instructions on
bleeding the fuel injection system.
USE DIESEL FUEL ONLY
Purchase diesel fuel in quantities that will be used
within 30 days, to assure freshness.
STARTING THE ENGINE
Remove all loads connected to the AC power recepta-
cles and the welder before starting the diesel engine.
1. Open the engine compartment door and check that
the fuel shutoff valve located above the clear plas-
tic fuel filter housing is in the open position (lever in
the vertical position). See Figure B.3.
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 300 D/DLX TO RUN OUT OF FUEL.)
