Saw blade guides
There are two saw blade
guides, one each at the left
(driven) and right (drive)
wheel sides and installed
on the sawhead frame.
The left-hand (driven-side)
saw blade guide can be
moved left and right by
loosening the lock handle.
Adjust the saw blade guide
distance to suit the width of
the work to be cut, so that
the saw blade can be
guided as close as
possible to the work.

saw blade speed control dial (for the HFA-250 and HFA-250W) or saw
blade speed control handwheel (for the HFA-400 and HFA-400W) at the
right side of the machine.
NOTICE
O Never turn the saw blade speed control dial or handwheel when the saw
blade motor is stopped.
