OPERATION
CHECK OIL LEVEL IN POWER TRAIN CASE, ADD OIL
1. Remove dipstick (G), and wipe the oil off with a cloth.
2. Fully insert dipstick (G) into filler pipe, then remove it.
3. Check that the oil level is between the H and L marks on
dipstick (G).
If the oil level is below the L mark, add oil through oil filler (F).
The dipstick has two sides for checking the oil level: COLD
STOP for use when the engine is stopped and the oil
temperature is low; and HOT IDLE for use when the engine is
idling and the oil temperature is high.
REMARK
When checking the oil level with the engine stopped before
starting operations, check the oil level with the side marked COLD
STOP. It is also possible to check the oil level even after starting
operations when the power train oil temperature is high,
but in this case, run the engine at idling and use the side marked
HOT IDLE.
4. When hydraulic oil is above the H level, remove drain cover (1)
on the left side of the power train case bottom, take out drain
plug (2), drain excess oil by loosening drain plug (3) and then
check the oil level again.
5. If the oil level is correct, tighten the oil filter cap securely.
REMARK
When inspecting, if the machine is at an angle, move it to a level
place to carry out the check.
