to access the lubrication nipple.
a = Cover
2. Raise the machine with the equipment by activating
the command lever.
3. Loosen the greaser.
4. Let the grease escape so that the track will extend.
WARNING
Do not loosen the greaser by more than one turn.
If it is loosened suddenly, the high pressure grease
inside may escape or the valve may be ejected,
which may cause serious injury.
When you check whether the grease has escaped, do not look inside the greaser but
check that the track is released. Do not place your face, hand, legs or body in the direc-
tion of the greaser.
It is very dangerous to remove the grease using procedures other than those described
here. If the track cannot be relaxed, ask your YANMAR dealer to intervene.
