Loosen the valve (2), remove the grease, and tighten the
valve (2).

Do not loosen the valve more than one turn. Other-
wise the valve may fly out due to the high internal
pressure of the grease.

fuel control dial at MIN (low idle) position, and move the
machine slowly forward by length of track on ground, then
stop the machine.
