SYSTEMS OPERATION
When the inching pedal is depressed all the way
and plunger 1 is moved 16.5 mm (0.65 in.) of its
stroke, inching spring 6 restores to free stare,
causing return spring 7 to move valve 5 to the
right.
This will completely stop oil flow to
passage 4, and passage 4 and passage 8 are
communicated to each other without being me
tered. Consequently, secondary pressure falls to
zero and the machine is brought into a complete
stop as in neutral.
In summary, the inching pedal may be used like
the clutch pedal of a direct-drive model. The
machine can be started smoothly by depressing
the inching pedal quickly all the way to the end
of its stroke and then releasing it gradually to a
position within the range of 4 to 16.5 mm (0.16
to 0.65 in.) of the stroke of plunger 1, depending
on the load, to gradually increase the pressure
acting on the directional clutch piston.
