INSPECTING THE FUEL LEVEL
WARNING
• Do not smoke or permit open flames
while handling fuel or working on the
fuel system.
• Never remove the fuel cap or add fuel
when the engine is running or still hot.
Do not spill fuel on the hot surface of
the machine.
• Fill the fuel tank in a well ventilated
place.
• Clean up spilled fuel immediately.
• Do not fill the fuel tank to capacity.
Allow room for oil expansion.
• Securely tighten the fuel filler cap.
• Use the correct grade of fuel for the
operating season.
1. Check the fuel level using the sight gauge
(1).
2. If the level is low, add fuel from the fuel
port (2) while watching the sight gauge (1).
Refer to “Fuel filler port” on page 2-5.
INSPECTING THE HYDRAULIC OIL TANK
LEVEL AND REPLENISHING
WARNING
Oil may spurt out if caps or filters are
removed or pipes are disconnected
before releasing the pressure in the
hydraulic system.
• Gradually loosen the vent plug to relieve
tank pressure.
Inspection
The oil level changes with the oil
temperature. Inspect the oil by maintaining
the machine at posture shown in the figure at
the next.
• Machine posture for inspecting the
hydraulic oil level
1. Start the engine and run it at low speed.
2. Fully offset the boom to the left.
3. Fully retract the cylinders (arm and
bucket), and lower the bucket to the
ground.
4. Lower the dozer blade, and then stop the
engine.
5. Inspect the oil level using the sight gauge
(4).
When the oil temperature is about 20°C
(68°F):
The level should be between the upper
limit (H) and the lower limit (L).
If it is below the lower limit (L), replenish.
When the oil temperature is about 50 to
80°C (122 to 176°F):
The level should be slightly below the
upper limit (H).
