Correct Track Adjustment
Never visually inspect the vent holes or valves to see if grease or oil is coming out of them. Make sure the vent holes are clean before the tension is released on the track. Watch the cylinder to see that it moves.
Torque for adjustment and relief valves ... 35 7 N m (25 5 lb ft)For the correct track adjustment, use the procedure that follows: The track adjustment procedure should be performed under the same conditions in which the machine is used. Packing must NOT be removed from the track, if packing condition exist
