OPERATION MANUAL
TABLE ROTATION
The table rotates 45° left or right (Fig.5.4)
To rotate the table:
1. DISCONNECT MACHINE FROM POWER!
2. Remove as many items from table as possible.
This makes rotating the table easier.
3. Loosen the four hex nuts that secure table to
knee (see Fig. 5.4).
Note:
There are two hex nuts behind the table as
well.
4. Using the angle scale on knee as a guide,
rotate the table to desired position.
5. Retighten the four hex nuts that secure the
table to knee before resuming operation.
HEAD TILT
(HM-51B)The head tilts 90° left or right at the end
of the ram.
(HM-54GV) The head tilts 45° left or right at the
end of the ram.
To tilt the head:
1. DISCONNECT THE MACHINE FROM POWER!
2. Using a spanner, loosen anticlockwise the 3
hexagon nuts located at the rear of head end
of the overarm as shown in Fig.5.5
Please note that these
3 nuts must only be loosened one quarter to
one half (1/4-1/2) of a turn maximum to avoid
possibility of the head disengaging from its tilt-
ing mechanism and so dropping under its own
weight.
