CONCEPT AND MAIN APPLICATIONS
Models LH1040 and LH1040F have been
developed as multi-purpose miter saws.
Installation of a table on Model LS1040
has enabled miter saw and table saw to be
packed in one tool for great versatility.
LH1040F features LED built-in job light
for accurate tracing of ink line in dark places.
