OPERATION
CHECK OIL LEVEL IN HYDRAULIC TANK, ADD OIL
When removing the oil filler cap, oil may spurt out, so stop the engine
and wait for the oil temperature to go down, then turn the cap slowly to
release the internal pressure before removing the cap.
If oil has been added to above H mark, stop the engine and wait for the
hydraulic oil to cool down. Then remove drain plug (P), loosen drain
valve (1), and drain the excess oil.
1. Put blade on the ground and stop the engine. Wait for 5
minutes before checking oil level. Oil level should be between
the H and L in sight gauge (G).
If the machine is equipped with a ripper, put ripper point on the
ground, too.
NOTICE
If the oil level is above H line, do not add oil. Doing so may lead to damage
to the oil pressure circuit and spouting out of oil.
2. If the level is below L mark, add oil through oil filler port (F).
3. After adding oil, be sure to screw on the oil filler cap and lock
it with the key.
REMARK
When checking the oil level, if the machine is inclining, make it level
before performing the check.
