3.6 Leveling the machine cast iron table
IMPORTANT! Leveling the machine table is a complicated operation.
Ensure that this operation is necessary before beginning any adjust-
ments.
The machine table is already leveled from factory, but the table can have changed its
position by rough handling during transport or by the machine being subject to impact.
INDICATIONS THAT THE MACHINE TABLE IS NOT LEVEL
The upper cutter cannot be adjusted so that it is parallel to the machine table
The crank for raising and lowering the table is difficult or impossible to turn.
The chain that connects the trapezoidal threaded bars that holds the machine table
has come off or has moved incorrectly on a sprocket.
LEVELING THE MACHINE
1. Set the both bearing housings of the upper cutter in their lowest position. (See Initial
setup of upper cutter.)
2. Place an absolutely level block on the machine table directly head (not against the knives
or the knife slots).
3. If possible, turn the machine table crank until the block comes very close to the cutter. If it
is impossible to raise the table, you later have to take the measurement between the table
and the cutter head instead of using the block. This operation is slightly more difficult.
4. Loosen the chain for the machine table by opening the chain lock (take the opportunity to
clean and lubricate the chain).
5. Turn each of the threaded bars until the cutter head touches the block along its entire
length (alternatively, measure between the table and the cutter head). Each threaded bar
has to be turned a little at a time to avoid the table getting locked due to angular misalign-
ment. Do not use force.
6. When you are satisfied with the table’s lateral position, check the table’s position length-
wise in the machine by measuring its height against the upper edge of machine frame,
and level the table in this direction as well.
7. Ensure that all the threaded bars are easy to turn. If any of the threaded bars is difficult to
turn, it is due to angular misalignment of the table. Adjust this by slightly turning the diffi-
cult bar, even if this results in the table being not completely level. This deviation is taken
care of by fine-tuning the position of the upper cutter. (See Initial setup of upper cutter.)
