The lower trunnion is attached to the body of
the saw by four hex headed bolts.
These may be slackened and the trunnion
slid in either direction until the blade is
centred.
After adjustment, tighten them securely.
Adjustable pointer.
This lever locks and unlocks the trunnion so
that the table may be tilted.
Having set the table so that the blade is
centred, apply a little tension to the blade
and use a set square to position the table at
right angles to it.
Lock it in position and if necessary, adjust
the pointer so that it aligns with the zero as
shown above
