The machine, equipped with a quick-fit tool, remark-
ably facilitates the tools unit extraction/rotation opera-
tions. Here follows the description of these operations:
TOOL ROTATION
To rotate the tool head (
Fig. 22 - 23 ref. 1
) (both in
lower position (
Fig. 23 ref. 2
) and in upper position
(
Fig. 22 ref. 3
)) just push the unlocking lever (
Fig. 22
- 23 ref. 4
) towards the tool arm. When the new work-
ing position of the head is reached (
Fig. 22 - 23 ref. 1
)
the lever (
Fig. 22 - 23 ref. 4
) automatically inserts
locking its rotation.

IN WORKING POSITION, THE COU-
PLING LEVER (FIG. 1 REF. 23)
MUST BE CORRECTLY HOOKED
HOOKED TO THE TOOL CAR-
RIAGE CLAMPING PROFILES (SEE
FIG. 21).
When the tool holder arm is in “off-work” position, it
can be laterally shifted in manual mode in one of the
two pre-set positions on the carriage, so that it can
better positioned (according to the operations to be
performed afterwards) before it reaches “working”
position again.

To shift from “work” position to “off-work” position
and vice versa, the tool holder arm moves by pushing
the pedal provided (

) .
When the tool holder arm is in “off-work” position, it
can be laterally shifted in manual mode (
NAV41.13N,
NAV41T.13N, NAV41.13EI
and
NAV41T.13EI
) or
in automatic mode (through an hydraulic cylinder)
(
NAV41.13SA
and
NAV41T.13SA
) in one of the
two pre-set positions on the carriage, so that it can
better positioned (according to the operations to be
performed afterwards) before it reaches “working”
position again.
