BEFORE STARTING THE ENGINE
Check the engine oil level:
See Engine manual 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 the Oil Bath Air Cleaner:
With normal operating conditions, check the oil level in
the air cleaner daily. Refer to the engine manual for
the oil grade and other servicing information.
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 6-8 inches (150-200
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.

6. Check that the charge indicator light is off and that the oil
pressure gauge indicates that there is sufficent oil pres-

minutes before applying a load and/or switching to high
idle. Allow a longer warm up time in cold weather.
STOPPING THE ENGINE
1. Remove all welding and auxiliary power loads and let the
engine cool by running it for several minutes at low idle.
2. Stop the engine by pulling the stop cable and hold it ‘out’
until engine has stopped. A fuel shut off valve is not
required on the RANGER 8+ DIESEL because the fuel
