METHOD FOR CHECKING BEFORE STARTING
Always check the items in this section before starting the engine each day.
METHOD FOR DRAINING WATER AND SEDIMENT FROM FUEL TANK
1.
Place a container to catch the drained oil under the drain
valve at the lower part of the fuel tank.
2.
Loosen the drain valve to drain all the sediment and water
accumulated at the bottom together with fuel.
3.
When only clean fuel flows out, close the drain valve.
METHOD FOR CHECKING LOOSENESS OF WHEEL HUB BOLTS, RETIGHTEN-
ING BOLTS
Check the wheel hub bolts (1) for breakage or looseness.
If any wheel hub bolt (1) of a wheel is broken, replace all the
wheel hub bolts (1) for that wheel.
If any bolt is loose, retighten it.
Tightening torque: 1519 to 1852 Nm {155 to 189 kgm}
Insert a socket wrench in a pipe, then apply a force of 1685 N
{172 kg} at point 1 m from the fulcrum. This will give a tighten-
ing torque of 1685 Nm {172 kgm}.
When the hub bolts are tightened after the tires are replaced,
drive the machine for 5 to 6 km, and check the tightening tor-
que to ensure that there are no loose bolts.
METHOD FOR CHECKING OIL LEVEL IN TRANSMISSION CASE, ADDING OIL
NOTICE
• The oil level changes according to the oil temperature, so check the oil level after completing the
warming-up operation. If the machine is used under the condition that the oil level was checked
when the oil temperature was low, the components may be damaged.
• Be sure to check the oil level while running the engine at low idle and after completing the warming-
up operation. Consider the oil level check when the engine is stopped only as a guide.
